Brief Summary

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.

Study Population

Patients who refered to the Clinic for Prosthodontics due to the lack of one or more teeth that need to be replaced with dental implants and healthy completely dentate volunteers.

You may qualify if:

• For the Test Group
• patients with implant-supported fixed restorations in at least one quadrant of the posterior region (pre-molar and molar) of both jaws at least for 1 year
• patients with Angle Class I in MIP
• patients who did not have orthodontic treatment
• \- patients with completely dentate arches (not considering third molars) with a maximum of 4 tooth-supported restorations per dental arch).

You may not qualify if:

• patients with bruxism, detrimental habits, and mandibular parafunctional activities
• patients with signs of temporomandibular dysfunction, trismus, or illness of the cervical spine
• patients with a history indicating problems with alcohol or drugs or receiving any psychiatric treatment.
