The prototype is a branch of dental medicine that deals with the recovery of lost teeth. Also, the purpose of prosthetics is to provide, besides the function, perfect aesthetics.
The prototype covers two branches:
The total prostheses compensate for all the missing teeth in the mouth. Their preparation depends on the anatomical structure of the jaw that is formed after the extraction of the teeth.
A partial prosthesis compensates for the lack of more teeth if this is not possible to be done by using a fixed solution. It can be acrylate in its fullest, which is an advantage if you need to add a tooth that is lost after prosthetic rehabilitation or metal-skeletal (visceral prosthesis).
Vision (skeletal) prosthesis
The base of this prosthesis costs an alloy (nickel-cobalt chromium) and from there runs its name. The remaining part of the prosthesis, which compensates for lost teeth, is made of acrylate. The use of the visil prosthesis is quite common and is used in cases where the arrangement of the remaining teeth does not allow the production of a fixed prosthetic solution. In our practice, we make two types of these prostheses:
●Classic visceral prosthesis
This type of skeletal prosthesis adheres to other teeth using specially designed cast hooks, which are made of the same alloy as the base of the prosthesis. The hips hold the solid prosthesis but are elastic enough to remove the prosthesis and clean the remaining teeth.
●Visil prosthesis with preparation
This type of visitor prosthesis solves the aesthetic problem of the classical prosthesis or the visibility of the hooks. In this case, a special way of tying with the rest of teeth, and with atheists and obstacles, is applied. In order to achieve the aesthetic effect, the remaining teeth should be processed and placed under crowns.
This type of prosthesis is a temporary solution at a loss of one to two teeth in order to achieve a quick and simple aesthetic restoration and restore the patient’s self-confidence.
Restoration of prostheses
In addition to making new prostheses, it is sometimes necessary to repair the old ones in order to improve the oral cavity.
Also, sometimes there is a need for adding teeth and repairing the breaks of existing prostheses.
A crown is a prosthetic compensation that covers the tooth in order to restore its shape color and function. The boxes are needed when the tooth is so damaged that sealing will not solve the problem. The crowns are used for fixing bridges, protecting teeth from fractures and covering the bad shape of teeth and possibly when they are darkened. There are many types of crowns that can be divided into 3 groups depending on the material they are made of.
They can be metal, metal-ceramic, completely ceramic.
Metal crowns (mostly golden) have been used in the past but today they are almost unused. Today, metal ceramic crowns are the standard most of the patients are looking for. Such crowns have a metal base on which the ceramics are baked. The last category of crowns are completely ceramic and very aesthetic (CAD-CAM, cirkonia).
In order to be able to make a crown, the need is to be processed (erupted), then a fingerprint is sent to the dental laboratory.
Following this procedure it is desirable to place a temporary crown on the tooth, which aims to protect the tooth from external influences and also has an aesthetic role.
Dental bridges are indicated when one or more teeth boast in the mouth. They are prosthetic structures that connect the carriers and compensate for the missing teeth. The carriers of the bridge can be natural teeth or dental implants, one or more teeth may be missing between them, and the goal of making the tooth bridge is to restore the aesthetics and function of lost teeth. The construction of the bridges takes place in several working phases. The number and length of the phases depends on the technology of making bridges, the purpose of the bridges (temporary or durable), and the material they are made from. Dental bridges usually last 5 to 15 years. With good oral hygiene and regular checkups, it is not uncommon for the durability of the bridges to be more than 10 years old. After that period it is necessary to replace the tooth bridge, especially if there are changes in the level of soft tissue and tooth bone, which is certainly a natural process followed by aging.
The advantage of these bridges is that one or two lost teeth are compensated without removing the glances from adjacent teeth that restrict the empty space. They are most often used as a temporary fixed solution while the permanent replacement is not made.
