The dental implant, is a device intended to be a substitute artificial root of a missing tooth. Usually has a threaded and is made of biocompatible materials that do not produce rejection reaction and allow binding to the bone. The implant surface may have different textures and coatings, commonly used to increase adhesion to bone (osseointegration of titanium and if biointegration case of a ceramic material).
By replacing missing teeth by implants is preserved as much as this alveolar bone is resorbed by not receiving any stimulus.
Is the portion of the dental implant that is designed to be inserted into the bone to anchor the prosthetic components, generally screw-like but also to other types. In turn, This body is composed of 3 parts, which are:
Is the upper.
It is the intermediate portion.
It is the end point or end.
After inserting during 1. Th stage surgical implant body in the bone, cover is placed on the crest module, in order to avoid tissue growth on the inside of the thread which has said module or upper portion.
After osseointegration has occurred is performed 2. Surgical Stage, in which unscrewed and removed and the cover screw is screwed healing abutment, whose function is to extend the body of the soft tissue implant, and allow binding of the mucosa at the gingival crest module, giving birth to the gingival sealing.
There are different types of prosthetic connection, among the best known can name:
Connecting to external hexagon
Internal hex connection
Connection type "Morse taper", friction connection
The portion of the implant that holds the prosthesis. According to the method by which attach the prosthesis to the implant, distinguish three types of columns:
Pilar screwedIt uses a bolt or screw to fix the prosthesis.
The prosthesis is attached to the pillar by dental cements, behaving like a stump that is attached to a crown, a bridge, or overdenture.
It consists of an anchoring system that will support a removable prosthesis, that the patient can manually insert and remove.
