Influence of Two Different Occlusal Schemes Following Single Molar Implant-supported Restorations.

Occlusal overload may lead to a number of complications; biological and mechanical such as crestal bone loss, screw loosening, prosthetic fracture and even implant failure . Inadequate occlusal scheme (occlusion) causes occlusal overload increasing mechanical stresses which are transferred to the crestal bone and implant interface, leading to complications such as; Early implant failure, Early crestal bone loss, Intermediate to late implant failure, Intermediate to late implant bone loss, Screw loosening (abutment and prosthesis coping), Uncemented restoration, Component fracture, Porcelain fracture, Prosthesis fracture and Peri implant disease .Thus, a proper implant occlusal scheme plays a major role in the outcome of the implant treatment modality.

Treatment and study plan

Maximum Intercusption

Procedure

to evaluate crestal bone loss, chewing efficiency and prosthetic complications after single posterior implant restoration in protective occlusion in comparison to maximum intercuspation occlusion.

Protective occlusion

Procedure

To evaluate crestal bone loss, chewing efficiency and prosthetic complications after single posterior implant restoration in protective occlusion in comparison to maximum intercuspation occlusion.

Primary outcomes

  1. Marginal Bone Loss

    Time frame: 2 years

    • To evaluate marginal bone loss using bitewing radiographs in mm.

  2. Stability

    Time frame: 2 years

    • to assess implant micromotion in both groups by resonance frequency analysis (Osstell®) in mm.
