Fallot prosthesis (Prosthetic of Penis)
To date falloprotezirovaniya (penile prosthesis) is a radical method of treatment of erectile dysfunction. Treatment involves the introduction of a silicone prosthesis in the cavernous body of penis. Developed several types of prostheses, and about which we will discuss below. Now stipulate to the testimony falloprotezirovaniya:
· Vascular (vasculogenic) erectile dysfunction
· Ineffectiveness of conservative treatment of erectile dysfunction
· Erectile dysfunction in Peyronie's disease
· Presence of artificial (artifitsialnogo) of the penis, as a result of the operation to change the penis
· Erectile dysfunction in diabetes and other metabolic diseases
· Erectile dysfunction as a result of radical interventions on the prostate, rectum, bladder
· Cavernous fibrosis
· Psychogenic erectile dysfunction, with failure of all conservative treatment methods |

Technologies of prosthetics
Violation of the joints, causes a person to ispytyvatpostoyannye pain and discomfort during movement. Some pytayutsyareshit problem of medication, but most effektivnymsposobom considered enodprotezirovanie damaged joints. The success of the prosthesis depends on the technology of prosthetics.
To date, orthopedic surgeons use three tehnologiiprotezirovaniya - cement, cementless and hybrid. When vyboreopredelennoy technology, the physician takes into account the type of damage, vozrastpatsienta, his physical condition, susceptibility to various diseases and lifestyle. Since the elderly are encouraged to cement prosthesis, which allows to fix the joint using a special bone cement. It is caused by the slow rate of healing of bone tissue in the elderly. Cement protezirovaniepozvolyaet speed the cure the patient.
Cementless prosthesis requires germination of Environmental Bone vpoverhnost prosthesis. Zazhivleniyauvelichivaetsya lengthy process, but it achieved a better effect. Patsientsmozhet engage in active sports, move razlichnyetyazhesti in general lead a fulfilling life. In addition, this vidprotezirovaniya has minimal effect on the human body.
The hybrid method is used for complex cases, such as hip replacement. He copes with heavy povrezhdeniyamisustavov and promotes faster recovery of the patient. Gibridnoeprotezirovanie united all the positive qualities of the previous methods is a small rehabilitation period, excellent results poslevyzdorovleniya and a small effect on the human body.
After the prosthesis is necessary not to forget about rehabilitation periodepatsienta. For more effective healing of joint rekomenduetsyaispolzovat physiotherapy, massage, obuchenienormalnomu use a limb, a return of sensitivity ipravilnuyu biomechanical evaluation of the patient limb. In addition, it is worth recalling the patient about vozmozhnyhoslozhneniyah - biases, and distorted or worn parts of the prosthesis arthroplasty, osteolysis, infection, bone fracture of the prosthesis, offset and tissue response to prosthesis.
The success of the prosthesis depends on the choice of method, as well as эффективностиреабилитационных measures after the operation. Endoprosthesis spastisustavy capable of more than 80% of patients. |

Dentures made of wood - a revolution in prosthetics
Known since childhood pirate wooden dentures and hooks attached to any novel or movie mystery and excite the curiosity of young viewers. Unfortunately, in life have to deal with people who are forced to use artificial limbs to replace lost organs or bones. The main objective of setting "the bone substitutes is a partial return of the functionality of mutilated limbs. Until recently it was thought that the wooden dentures forever gone, along with fabulous pirates, but surprisingly all Italian scientists have refuted it, and under the guidance of Anna Tamperi created a unique material for the manufacture of bone implants, based on tree structure.
As confirmed by the researchers, the structure of wood is very similar to the structure of human bone tissue. This feature of the doctors mentioned in all ages, but until now the tree was considered unsuitable for prostheses because of its propensity to rot. Italian scientists have our way out - they are heated wood to a very high temperature, thereby removing it from water and proteins, and then left the skeleton of wood. Then, as a result of complex chemical reactions, the interaction of carbon dioxide and oxygen formed calcium carbonate - a white material, which by its structure is almost indistinguishable from the real bones. The new bone material have been created microscopic holes and channels, which contributes to more successful integration of the prosthesis into the human body. Prior to this synthetic analogs that have been applied in similar experiments, could not withstand the test and often rejected by the body. Even such a popular material such as titanium is considerably inferior to the new invention.
The advantage of using tree structures is that similar designs can withstand considerable pressure, according to Ian Gibson, a professor at Aberdeen University. On the basis of "woody" materials in the near future will be made first prostheses - Part bones broken as a result of accidents or after serious surgery. While it must be noted that the new material has not been studied enough to make it possible to fabricate not fragment, and the bone completely, but still ahead.
In the near future, scientists plan to begin work on creating an integrated implant and promote new technology in other fields outside of medicine. |

Prosthesis on telescopic crowns
Every patient coming to the dentist wants to get comfortable and durable prosthesis, especially when it comes to portable designs. To date, of all the interlocking telescopic dentures are probably the most reliable. Telescopic prosthesis consists of two parts. The first part, the primary crown is fixed on the tooth. The second part is itself prosthesis in which the secondary crown.
To remove the prosthesis on telescopic crowns do not have to open a different gate (latches) and push buttons. He simply removed, and also just getting dressed. Teeth are covered by telescopic crowns do not have a functional overload, as the load on the tooth is strictly along the axis of the tooth. Therefore, even highly mobile teeth can be used as a support for the telescopic dentures. In the case of the loss of a telescopic denture abutment teeth do not have to redo it. All locking prosthesis in this case is not repairable and will need to rework the whole structure.
Telescopic prostheses retained on the teeth using double (telescopic) crowns. One part is a metal cap with parallel walls, fixed on the tooth. Another part of it may be a bridge or a removable clasp protetezy.
At a fixed prosthesis secondary part exactly sits on its primary crown and by the force of friction (metal to metal) prosthesis is held in the mouth.
The more teeth covered by telescopic crowns, the stronger the fixation of the prosthesis in the mouth.
During the operation (about 3-4goda), due to friction, crowns and dentures are free to lose a little traction with his teeth. To improve the fixation of telescopic prostheses in Germany has developed a system FGP (Friktions-Geschiebe-Passung).
In a free telescopic crowns paid HRF. The prosthesis is fixed in the mouth, after 5 minutes remove the prosthesis. Due to the transition to a plastic-metal friction force adjustment is achieved by the force of adhesion to the denture teeth.
At the time of manufacture the prosthesis can be pre-lay design elements that will keep the denture in the mouth.
Galvanic cap-is located between the primary and the secondary part of the telescopic crown. When loosening of prosthesis fixation, he is given to the laboratory where using electroplating restore the cap.
To fix the use of magnetic alloys (magnets). Primary and vtorichnyekoronki attracted to each other. Very reliable, no need to change and add many years to come.
Using a sapphire ball in the secondary structure prosthesis. In the primary cap is a small indentation. At a fixed prosthesis sapphire ball falls into a pit on the primary crown and well-captures the prosthesis in the mouth. During the operation does not require any correction since the prosthesis does not lose adhesion forces to the teeth than ever before. The most popular type of fixed prosthesis. |

The first artificial eye. Who made them? Who was the first prosthetist?
History of eye prosthesis goes into the mists of time. It is known that artificial eyes made even in ΙX BC. Residents of Babylon, ancient Egypt, China and the Aegean region, believed in an afterlife, not only loaded with jewels coffins of their relatives for burial, but also inserted the artificial eyes in the orbit of their mummies.
In the Egyptian mummies and mummies in the tribes that lived in ancient times, the American continent, discovered simulate eyes, made of precious stones, marble inserted in it with colored glass, gold, silver, coated with enamel, ivory, etc. . Such products have been so jewelry made that during the excavations of archaeologists terrified at their "bright eyes".
For the first time artificial eyes for living people have been made in the V. BC Those engaged in the Roman and Egyptian priests, who also had a medical practice.
Despite the ancient origin of the ocular prosthesis, most people almost the whole history of humanity was forced to use a dark bandage - a patch to hide the disfigurement.
The real story of eye prosthesis begins from the time of Ambroise Pare (Ambruoize Pare), a French surgeon and a dentist who lived in 1570-1590gg. He published drawings and calculations of glass and porcelain dentures skorlupopodobnyh, relevant, today's thin-walled. These glass eyes are a little earlier Venetian. The development of glass-blowing in the XIV century. Venice allowed mass produce ocular prostheses, but the master glassmakers kept production methods secret. Soon the best craftsmen moved from Venice to France, where the prostheses at the end of XVΙΙΙ. reached a high perfection. These patients came from different countries to get an eye prosthesis. Several families of skilled glassmakers perfected the technology and kept the family secrets, and make a profit. The best artists in the late XVΙΙΙ. were A. Miro, Boisson, Jerdan. Their names were known throughout Europe. At this time, however, the use of ocular prostheses was limited, the reason for this has been their high cost and difficulties of travel to Paris because of the absence at the time of railways. In 1851 the French prosthetic settled in the United States by establishing a firm «Mager and gougelman», still exists today.
In the 30-40 years XΙX century began to develop prosthetics in Germany. L. Muller, a skilled German glass-blower, not only caught up but surpassed the French masters, he founded his company, soon became widely known. In the first decades of the century for the manufacture of ΧΧ ocular prostheses have been tried many substitutes, fragile glass, among them aluminum, ivory, rubber, celluloid, etc. But all these materials were not suitable for prosthesis. Up to 40 years in the course were the only glass prosthesis, the main supplier of whom were German companies. Since the beginning of World War II, imports glazoproteznogo glass eye prostheses in the UK, USA, Canada and other countries stopped. Stocks prostheses in these countries were small, and its own production of high quality glass to organize failed. Therefore, in the UK and the U.S., based on the experience of dental prosthetics, have begun to develop technology for making artificial eyes from polymethylmethacrylate. The material was very comfortable and technologically advanced, and in 1944 was already organized the mass production of new products. The widespread introduction into the practice of plastic ocular prosthesis was a qualitatively new stage of development of ocular prosthetics. Plastics has achieved successes that would have been unthinkable when using glass-blowing techniques. |

Dentures fasten securely
Time can not be reversed, it inexorably moves forward and puts its stamp on everything, especially for us. Over time, the human body begins to age, this process is irreversible so far, but we try as much as possible to slow down, and modern medicine to us this helps. For example, with age a person starts to lose his teeth, and to disguise these losses, the dentists have invented a substitute for teeth - dentures.
Prosthesis can be virtually any defects in the dentition, the choices among different types of dentures are extensive enough. There are implants, removable and non-removable dentures. The most common are dentures. Among denture allocated directly, then there are those who put immediately after tooth extraction. Usually they put the time in order not to change the position of remaining teeth, and later replace the ordinary. Ordinary same prosthesis - a prosthesis that are placed after some time after tooth extraction. There is also a division of removable dentures in partial or complete, depending on the number of lost teeth.
Denture restores chewing function and serves to prevent changes of the remaining natural dentition, providing stability and shape of the bite. Choose the type of prosthesis - a serious problem, and it can be solved only with a qualified dentist, who will consider the specific situation, as all types of prosthetics have limitations. But in order to know from which one can choose to have at least a general idea of what generally are dentures.
Implant (from Lat. Im - «in, inside and plantatare -« planting, transplanting ") - is an artificial material that is implanted into the jawbone and serves as a basis for further constructions. The implant can be placed fixed prosthesis, and prosthesis on implants last longer conventional dentures. You can use the implant for improved retention of removable dentures. In some cases, the implant is put immediately after tooth extraction. On engraftment of the implant takes time - on the upper jaw 6 months, at the bottom - 3 months. Cosmetic defect at this time can eliminate the temporary prosthesis.
Fixed prosthesis called the crown and bridge prosthesis.
By dentures are such prostheses that can be drawn from the mouth and set his mouth itself. They are used when a patient remains in the mouth is not enough teeth to use them for non-removable prosthetic dentures.
Being a foreign body, dental prostheses in some way affects the organs of the oral cavity. A person gets used to the denture immediately, the damaged functions of masticatory apparatus is gradually being restored. The most keenly felt the presence of the prosthesis as a foreign body in the mouth during the first 1-3 days of use to them. At this time there are difficulties in conversation, often changing the pronunciation of certain sounds. Complete habituation to the prosthesis occurs on average within 3 weeks. Duration of addiction prostheses depends on the overall state of the organism, the time elapsed since the loss of teeth, the individual patient, as well as the design of the prosthesis. Best man accustomed to the prosthesis with the direct prosthesis, that is, when you install the implant immediately after tooth extraction. The prolonged absence of teeth significantly complicates the process of addiction and increases the time for adaptation. Repeated prosthesis of the term addiction to the prosthesis is reduced.
Period of adaptation to the prosthesis can facilitate and smooth the discomfort and psychological distress, which often arises from fear that the dentures will fall out. Correction of the prosthesis and medical supervision during the first week, and the use of special means for fixing prostheses to help faster and easier to get used to new teeth.
Because problems with artificial limbs are different, and require different tools. Wide choice of means for fixing dentures PROTEFIX ® lets you choose what you need in each situation.

Ancient prosthetic of eyeball
|
In December 2006, archaeologists discovered in Shahr-i-Suhte ancient prosthetic eyeball, hemispherical shape with a diameter of just over 2,5 cm It is made of very light material, presumably bitumen paste. The surface of the artificial eye is covered with a thin layer of gold, its engraved in the center of a circle (representing the iris) with golden lines radiating in the form of rays. Women's remains, next to which the artificial eye discovered, had increased 1.82 m - is much higher than for the average woman of that time. On both sides of the artificial eye were drilled fine holes through which pass through the gold wire, through which the eye was fixed in the orbit. Microscopic studies have found traces of gold wire, which indicates that the artificial eye is constantly used. The skeleton dates from a period of about 2900-2800 years. BC. er. |

Implants
|
Implants - a class of medical devices used for implantation into the body either as a prosthetic (replacement of missing human organs), or as an identifier (eg, a chip with information about pets, implantable beneath the skin ). Dental Implants - Implants kind used for implantation in the bone of the upper and lower jaw as a basis for attaching a removable and non-removable dental prosthesis. |

Endoprosthesis of the hip
|
Its a replacement of the neck and the femoral head on a metal prosthesis. In the hip bone is built cup, there are options with a ceramic (aluminum oxide) or polyethylene insert is inserted into the thigh length of the leg with a ball-tipped on the cervix. Spherical part, too, is a ceramic. Leg prosthesis is smooth - and then attached at the hip on a special cement, and is porous, so that could increment without cement. Option without cement is less suitable for the elderly. The main complication - iatrogenic osteomyelitis (abscess) that occurs with very high probability when installing a prosthesis after nailing, and at other contraindications, which are quite a lot, but many doctors are now most of them tend to ignore. Suppuration is the plan of Bacteriological (streptococci, staphylococci, etc.), viral (for example, it could be herpes), or fungal and fight it with the means - antibiotic, antiviral and antifungal drugs, especially if the specific cause can be identified as a result of punctures and crops. On arthroplasty in Russia extends the practice of budgetary allocations "to high-tech help - quotas. For quotas and to perform operations under the quota queue for a year and a half. This is not emergency care and save lives, but only "to improve the quality of life" - almost like plastic surgery. It is believed that you can wait or not do. |

Artificial hands

Artificial hands in the XIX century. section. to "working hands" and "beauty hands," or luxury items. Laborer for a mason or restricted. overlay on the forearm or shoulder brace of leather sleeves with reinforcement, to which was attached the relevant professions tools - pliers, ring, hook, etc. Cosmetic artificially. hands, looking for employment, lifestyle, level of education and other conditions, there were more or less complex. artificially. hand could take the form of natural, in a graceful kid glove capable of producing fine work, write and even shuffle the cards (known as the hand of General Davydov). If the amputation did not reach the elbow, then using artificially. hand it was possible to recover the function of upper limb, but if the amputated upper arm, the hand work was possible only through the bulky, highly complex and require more effort aids. In addition to the latter, artificial. upper limb consisted of two leather or metal sleeves for the upper arm and forearm, which were above the elbow joint mobility in the joints are connected by metal tires. Byla brush is made of light wood and still attached to the forearm or mobile. In the joints of each finger finds. spring, from the ends of the fingers are catgut, which conn. behind the wrist and continued. in the form of two stronger laces, and one by clicking on rollers through the elbow joint, attached to the upper arm to the spring, the other, also moving to block free ends ear. If you want to stretch out with a shoulder to keep his fingers clenched, this eye vesh. on the buttons, available on the upper arm. For an arbitrary flexing the elbow joint fingers meshed in this office and completely shut down if the arm is bent at right angles. For orders artificially. hands was enough to indicate the measures of length and volume of the stump, as well as healthy and hands, and explain the technique of goal, they must serve. |

History of Prosthetics
The first mention of prosthetics in history - an escape from captivity Greek Themistocles. Chained, he was forced to saw off his leg, and then ask a carpenter friend to make him a prosthesis.
Since then, prosthetics developed sufficiently small, the famous pirate hooks and wooden legs - prosthesis about the same level.
After the development of mechanics, closer to the present, began to appear more sophisticated types of prostheses, is well mimic the lost body part or even able to move through the built-in mechanisms.
But those were just the outer parts of the body prostheses, artificial limbs of the internal organs (eg AbioCor) appeared in the age of electronics, and modern medicine may be deleted altogether prosthesis with the latest stem cell technology, currently not yet fully developed. In addition to the prosthetic limb in modern medicine common procedure prosthetic joints, dental implants and cosmetic eye and other body parts. Cosmetic dentures are helping people to communicate with persons who are not used to communicate with disfigured people without undue emotionality. In addition to the prosthesis itself, the surgeons found a different solution of the partial return of the functionality of mutilated limbs. Thus, the German physician Hermann Krukenberg developed (after the First World War) Krukenberg hand - a unique "claw", which is made from the ends of the radius and ulna bones of the wounded with traumatic amputation of the hand. (Krukenberg procedure) |

Methods of fixation of dentures
• gel, cream, a special glue. Using them in the mouth normally attached full dentures - simply put, false teeth. And also - conditionally dentures, which are installed temporarily and then replaced with the permanent prosthesis or implant teeth. In addition, the glue - or dental cement - also attached veneers and Lumineers, records needed shade, which are firmly shut the front portion of the tooth, providing the effect of "Hollywood" smile. However, some specific types of dentures, which are fixed by using creams list is useless: it can be, and dental crowns (of any kind, from plastic to metal-ceramic)
• locks. This type of mount is especially popular when it comes to bridges. It is they who in the first place and attached to existing teeth Hooks (clamps) and locks (attached files). Although I must say that the creams as an additional means of protection has not been canceled, and in this case. If we compare the hooks and locks, the difference is striking: the first on the teeth are visible, while the second set from the top crowns, because locks look more aesthetically
• a flexible manner. Popular (and expensive) nylon denture is attached by a flexible framework of natural substances that without additional creams tightly adhere to the mucous membrane of the mouth. |

Clasp or nylon prostheses, how to choose?
Installation of removable dentures is probably one of the most affordable types of prosthesis. Inexpensive and very efficient method, not only with the partial, but also at a complete loss of teeth. Perhaps prosthetic dentures partial or, respectively, complete, and it replaces all the lost teeth. Partial dentures can stir both on the right or left side, and on both, including those at the lower or upper jaw. Two main types of dentures: clasp dentures and nylon dentures
Clasp dentures
"Byugel" - in German sounds like "arc". Clasp dentures consist of several parts: a metal frame (which includes the arc and fixing elements) as well as artificial gums with the attached teeth. As a basis for clasp prostheses used in a very light metal, which makes the prosthesis is almost weightless, so you can quickly get used to it. The presence of the metal frame allows you to use a minimal amount of materials, which are superimposed on top of it (used as an artificial gingiva), resulting in a prosthesis is practically not felt in the mouth.
By way of fastening, clasp dentures are divided into 2 types:
• Bar prosthesis on the locks (one fastener is located on an artificial tooth, the second on a nearby natural, while fixing almost brings discomfort, it is not noticeable, and some of the pressure is transmitted to those teeth, which is the second part of the castle)
• Clasp dentures with clamps (or special hooks that cling to the denture teeth, while not breaking their enamel)
Obvious advantages of clasp dentures
• Reliability and durability
• The load is on the abutment teeth, which is fixed prosthesis
• When mounted on the upper jaw is almost completely open sky
• You need to shoot only occasionally to clean the prosthesis
Cons clasp dentures
• The first time can bring some discomfort. At first need to visit the dentist often enough, especially if the dentures rubbing the gums
• Mounting Bar prosthesis is possible only if a certain number of teeth, for which he can cling to
• May have an allergic reaction to the one used in prosthetic metal
Nylon dentures
The most modern material from which made dentures - nylon. He has long pushed to the side of the bulky metal prostheses or acrylic. These dentures are made entirely of nylon, which does not cause allergies, does not collect harmful bacteria, it is also very soft and pleasing to the gum material.
Obvious advantages of nylon prosthesis
• No hooks or locks that are created from metal fasteners are invisible to prying eyes. Supporting structures made of the same material as the prosthesis itself
• Do not rub, they quickly get used to, because its use for the manufacture of nylon prosthetic material is very soft and pleasing to the perception
• Prostheses Nylon does not break, it's very flexible dentures, flexible (due to the nature of the material)
• Do not require maintenance, do not shoot at night, but needed a rare clean dentures by rinsing in running water
• Nylon dentures are almost invisible, as are made of translucent material, which is identical to the color of the gums
• Do not cause allergies, do not contain toxic substances and does not collect germs
Removable prosthetics - an ideal option for those who can not afford to allocate large amounts of cash for the installation of artificial limbs, but wants to have a beautiful and slim set of teeth. A nylon prostheses - a more modern form of removable dentures due to its convenience and ease of use of materials. |
