简要总结
The development of a implantology leads to an increasing use of implants in the treatment of care for the loss of one or more teeth. The question is whether the existing guidelines, originally formulated for the occlusion of natural dentition and conventional prosthetic treatment can be applied to the implant prosthodonticsDue to initial differences in the vertical mobility of teeth and dental implants, present in the same dental arch, although the model of occlusion is ideal, undesirable premature occlusal contacts on the fixed dental restorations on implants may be present.
Objective: To evaluate the effect of different head positions on dental occlusion of the natural teeth and fixed dental restorations on implants.
Methods: Volunteers with complete dentition would be included in this study as the Control Group. The Study Group would include subjects with fixed dental restorations on implants in the transcanine region. A T Scan III System will be used for occlusal analysis.
