The Basic Structure Principle Of Fixed Removable Denture
Removable Dentures are the "Removable Dentures" that people often say. Like the "prosthetic", "prosthetics" as "prosthetics", "Removable Denture" means that human beings do "obligations" of the teeth. Medical is the upper, mandibular teeth or all of the teeth after the creation of the restoration of the general term. Removable Dentures are divided into two types: pickable and fixed. Fixed Removable Dentures (commonly known as "fixed Removable Dentures") can not be worn by the patient themselves, and removable teeth (commonly known as "active Removable Dentures") can be easily taken by the patient wear.
Removable Dentures are divided into fixed Removable Dentures (fixed Removable Dentures) and removable Removable Dentures (active Removable Dentures) depending on the retention method. Fixed Removable Dentures are supported and retained by natural teeth on either side or on one side of the immediate area, and the Removable Dentures are adhered to the prepared natural teeth by means of a retainer. This type of Removable Denture because the patient can not take their own wear, commonly known as fixed Removable Dentures.
The basic structure of the fixed Removable Dentures is similar to that of the bridge engineering. Therefore, it is called the fixed bridge in medicine, and the bridge body, the retainer and the connecting body are the three important components of the fixed Removable Denture.
(1) bridge body. That is, artificial Removable Dentures, through the fixed bridge to restore the missing tooth shape and function of the part, mainly by means of retention and connected body connected. The production of bridge material, it is necessary to meet the requirements of natural beauty, but also have a certain degree of stiffness in the bite force will not damage the fixed bridge and damage the abutment.
(2) Retention body. Bone gaps on both sides of the natural teeth similar to the bridge bridge, medically known as abutment. The bridge body must be firmly placed in the tooth area, must be connected through a fixed device with the abutment, this device is the retention body. So that the retention of the body can withstand the bridge when the force formed by the various stress, and will not be loosened from the abutment, shedding or even broken, the preparation of the material to maintain a certain strength. Commonly used retainers have a crown, part of the crown, the crown inlay and so on.
(3) connectors. Is fixed and connected to the retainer, between the parts of the bridge. According to the connection can be divided into different fixed body (welded by the whole into a fixed connector) and the activities of the connection (stress interruption).
