What Materials and Reproducible Techniques May Be Used in Recording Centric Relation? Best Evidence Consensus...

Area of Science:

• Dental occlusion and prosthodontics
• Biomaterials in dentistry

Background:

• Accurate recording of centric relation (CR) is crucial for successful dental restorations.
• Existing literature on CR recording techniques and materials requires synthesis.

Purpose of the Study:

• To evaluate techniques and their reproducibility for recording centric relation (CR) in dentate and partially dentate populations.
• To assess the effect of different recording materials on CR reproducibility.

Main Methods:

• Systematic literature search using keywords: CR, interocclusal records, CR accuracy, CR reproducibility, CR technique.
• Analysis limited to Systematic Reviews, Randomized Controlled Studies, Meta-analyses, and Clinical Trials.

Main Results:

• Over 3500 articles were initially identified; 291 were selected for further analysis.
• Techniques including chin point guidance, bimanual manipulation, and Gothic arch tracing demonstrated comparable precision and clinical accuracy.
• Polyvinyl siloxane and polyether materials consistently showed superior performance across studies.

Conclusions:

• Multiple techniques for recording CR offer comparable clinical accuracy.
• Practitioner experience significantly influences the accuracy of CR recordings.
• Polyvinyl siloxane and polyether are recommended materials for CR recording; virtual capture requires further investigation.
