The Clinical Study Of Schemes Of Dental Implant Occlusion

Dental Implantology is the term used today to describe the anchoring of alloplastic materials into the jaws to provide support and retention for prosthetic replacement of teeth that have been lost. It is world-widely considered that as a successful implant, there should be no fiber tissue between the implant and the alveolar bone around it. Without the protection of periodontal membrane, we should pay more attention to the occlusion design, controlling the value and direction of occlusal force exerted on dental implants .The schemes of occlusion have great influence on the success of implant-supported teeth, because improper occlusion design will usually lead to the failure of implanted teeth, and increasing worldwide attention has been attracted to how to design a proper implant occlusion.Ten patients accepted implant-supported teeth therapy were observed, two of who were operated through progressive loading. Comparative studies of objective indices changes before and after occlusion adjustment, differences between objective and subjective indices of occlusion were carried through, which were aimed at providing some references on the clinical design of implanted teeth occlusion.Through the limited study, we could draw conclusions as follows: 1. The disparity between subjective feeling and objective examinationsof the patients accepted implanted teeth therapy : There are 3 patients whose subjective feelings are obviously different from the objective examinations; 2. Correct occlusion readjustment is indispensable for the occlusion design of patients accepted implanted teeth therapy. Through selective grinding, 9 patients' problems concerned about occlusion have been alleviated. 3. Occlusion design should be determined by the idiographic conditions of patients, such as the relationship between upper and lower jaws, the design of the restoration, the existence of cantilever, and so on. 4. Progressive loading (albeit limited period of observation) is good for positive osseointegration of the patients accepted implanted teeth therapy.Although the shortcomings of this report, such as study design, small number of implants and short period of observation, make it difficult to draw completely scientific supported conclusions regarding the occlusion design of implanted teeth, it is helpful in pursuing such a clinical investigation.
