[The reproducibility of bite registrations].

E Körber, H Landt

    Deutsche Zahnarztliche Zeitschrift
    |February 1, 1979
    PubMed
    Summary

    Reproducing the exact hinge axis of mandibular movement is highly difficult. However, using average measurements for a facebow is sufficient for general dental practices.

    Area of Science:

    • Dentistry
    • Biomechanics
    • Anatomy

    Context:

    • Accurate recording of the temporomandibular joint (TMJ) hinge axis is crucial for prosthodontic and orthodontic treatments.
    • Variability in individual anatomy poses challenges to precise hinge axis determination.

    Purpose:

    • To evaluate the reproducibility of determining the kinematic hinge axis of mandibular movement.
    • To assess the clinical adequacy of average facebow measurements for general dental practice.

    Summary:

    • The study found that achieving high-precision reproducibility (less than a few millimeters) of the mandibular movement hinge axis is practically impossible.
    • Despite the challenges in precise hinge axis determination, a facebow based on average measurements was found to be adequate for routine dental procedures.

    Impact:

    • Highlights the limitations of current methods for precise kinematic hinge axis recording.
    • Provides evidence supporting the use of average-value facebows, simplifying treatment planning in general dentistry.
    • Suggests that for most clinical applications, the high accuracy sought in hinge axis determination may not be necessary, improving efficiency in dental practice.
