Occlusal Schemes for Implant Restorations: Best Evidence Consensus Statement

Area of Science:

• Dental Science
• Biomaterials Science
• Restorative Dentistry

Background:

• Implant-retained restorations are prone to complications, with occlusal overload frequently cited.
• Understanding optimal occlusal schemes for dental implants is crucial for long-term success.

Purpose of the Study:

• To conduct a Best Evidence Consensus Statement on implant occlusal schemes.
• To evaluate the scientific evidence supporting current practices in implant occlusion.

Main Methods:

• Literature search focused on clinical trials, randomized controlled trials, systematic reviews, and meta-analyses.
• Expanded search to journal articles using keywords: dental implants, occlusion, and occlusal scheme.
• Included 15 pertinent articles after review and elimination of duplicates and non-relevant studies.

Main Results:

• A significant lack of high-level scientific evidence was found regarding specific occlusal schemes for implant restorations.
• Initial searches for high-level evidence (RCTs, systematic reviews) yielded no relevant citations.
• A total of 15 articles were ultimately included after a comprehensive review of journal literature.

Conclusions:

• There is insufficient scientific evidence to recommend a specific occlusal scheme for implant restorations to minimize complications.
• Current occlusal strategies used for tooth- or mucosal-supported prostheses can be applied to implant restorations.
• Further research is needed to establish evidence-based guidelines for implant occlusal schemes.
