Clinical Report: Comparison of Different Centric Relation Recording Techniques
Overview
This study evaluates the accuracy and reproducibility of three centric relation (CR) recording techniques using the OccluSense® digital occlusal analyzer. The anterior deprogrammer (ADP) method exhibited superior consistency compared to bimanual manipulation (BM) and chin-point guidance (CPG), reinforcing its role as the gold standard.
Background
Establishing a repeatable reference position for the mandible is crucial in various dental treatments, particularly in complete-arch restorations. Centric relation (CR) serves as the most widely adopted reference point for prosthesis fabrication. Despite numerous documented techniques for capturing CR, there is a lack of clinical studies rigorously comparing these methods.

Key Findings
ADP exhibited superior consistency as a CR recording method.
BM and CPG showed substantial initial agreement with ADP but declined in reproducibility.
Operator dependency was highlighted in manual techniques like BM and CPG.
Digital tools like the OccluSense® enhance objectivity in CR recording.
Clinical expertise remains essential despite the use of digital analyzers.
Clinical Implications
Clinicians should consider the anterior deprogrammer as the preferred method for recording centric relation due to its reliability. However, bimanual manipulation and chin-point guidance can serve as viable alternatives when performed by skilled practitioners.
Conclusion
The study underscores the importance of selecting appropriate CR recording techniques in prosthodontics, with ADP being the most reliable method. The integration of digital tools can enhance the accuracy of these recordings.
