Centric relation determinations: clinical and radiographic comparisons

M L Carwell, W T McFall

    Journal of Periodontology
    |July 1, 1981
    PubMed
    Summary

    Different methods for determining centric relation reveal varying occlusal contact points. The anterior guidance jig (CPJ) method most accurately located initial tooth contacts, while radiographic analysis of condylar positions was inconclusive.

    Area of Science:

    • Dental Occlusion
    • Temporomandibular Joint (TMJ) Biomechanics
    • Diagnostic Methods in Dentistry

    Background:

    • Accurate determination of centric relation is crucial for diagnosing occlusal discrepancies and TMJ disorders.
    • Various clinical techniques exist for establishing centric relation, each with potential variations in accuracy.
    • Understanding these variations is essential for effective treatment planning in restorative and orthopedic dentistry.

    Purpose of the Study:

    • To compare the accuracy of occlusal prematurity detection using three different methods for determining centric relation: bilateral mandibular manipulation (BMM), chin point method (CPM), and anterior guidance jig (CPJ).
    • To evaluate condylar positions in the temporomandibular joint (TMJ) using radiographic analysis following centric relation determination by CPM and BMM.
    • To identify the most reliable method for disclosing initial and secondary occlusal contacts.

    Main Methods:

    • Thirty patients were randomly assigned to three groups, comparing pairs of centric relation determination methods (BMM vs. CPM, CPM vs. CPJ, BMM vs. CPJ).
    • Clinical occlusal analysis was performed using each method to identify initial and secondary occlusal contacts.
    • Standardized transcranial oblique radiographs of the TMJ were taken for 10 patients using CPM and BMM, with subsequent tracing and direct measurement for condylar position analysis.

    Main Results:

    • The anterior guidance jig (CPJ) method demonstrated the highest accuracy in locating the initial occlusal point of contact.
    • The chin point method (CPM) effectively disclosed both initial and secondary occlusal contact points.
    • Bilateral mandibular manipulation (BMM) revealed the greatest number of tooth contacts, predominantly on the premolars. Radiographic analysis of condylar positions yielded inconclusive results.

    Conclusions:

    • The choice of method for determining centric relation significantly impacts the identification and location of occlusal contacts.
    • The anterior guidance jig (CPJ) appears most precise for initial contact detection, while CPM is effective for multiple contact points.
    • Current radiographic techniques, when combined with BMM and CPM, may not provide conclusive data on condylar positions relative to these occlusal determinants.
