- A prosthodontic occlusion for the edentulous patient should reconcile sound biological and functional principles to ensure optimal occlusal relationship
- There is no clear evidence that any one type of the several described occlusal schemes lead to better clinical outcomes in either complete denture or dental implant therapy
Variety of occlusal schemes
A choice of occlusal schemes can be employed for the prosthodontic rehabilitation of the edentulous patient. Clinical outcomes with different schemes continue to be debated and no one scheme has emerged as clearly superior. However, although the exact scheme chosen is not crucial, the clinician must ensure that once a scheme is chosen, the occlusion itself should be carefully designed, frequently evaluated and refined where necessary.
Initial views that implant rehabilitation would require or permit specific occlusal schemes have not been substantiated by clinical findings. There is only limited scientific evidence that occlusal overload is a precursor of peri-implant bone loss or implant loss.
Nevertheless, several well accepted basic principles are common to most occlusal schemes. The following determinants should be followed:
- Acceptable interocclusal distance
- Maximum number of bilateral center stops during closure
- Freedom in retrusive range of contact
- Multidimensional freedom of contact movement
