This study was designed to investigate the biomechanical interactions in endodontically treated tooth implant supported prosthesis with variations in implant system and load type by using the nonlinear finite element (FE) approach.
The means of the underlying studies are displayed either weighed on patients' base (=PatWeigSurv, PatWeigSucc) or on units' base (implant, tooth, or prosthesis) (=UnitWeigSurv, UnitWeigSucc) Fig. 3 The diagram shows annual failure rates of the four treatments (implants, tooth autotransplants, preserved deciduous teeth, and conventional prostheses on teeth).
Dental implants, in the same way, can also be used to retain a multiple tooth dental prosthesis either in the form of a fixed bridge or removable dentures.
The types of prostheses were classified into implant-supported fixed prostheses, tooth implant-supported fixed prostheses, and implant-supported overdentures.
Oral health protocols are mainly based on the daily removal of bacterial plaque from teeth or prostheses (or both), cleaning of oral mucosa, and continual oral hydration.
1, 2 The stability of the jaw occlusion of the posterior teeth or prostheses is important for the swallowing function.
With this technique it is difficult to control the size of the interfacial area and the stress distribution, mainly shearing stress, through the tooth-cement-prosthesis junctions.
Potential fracture might be reduced by practitioners being aware of risk factors such as the post preparation technique, post selection, coronal restoration, and inappropriate selection of tooth abutment for prosthesis [ 39].
Untimely extraction of deciduous teeth may lead to earlier-than-normal eruption of permanent teeth, with displacement likely, while extraction of permanent teeth may lead to over-crowding and drifting of remaining teeth if no prosthesis is placed [ 23].
