Abstract
Purpose: By visualizing and verifying the relationship between jaw movement and occlusal surface contact using a jaw movement measuring device (JMAnalyser), this study examined the clinical utility of the device.
Materials and Methods: For patients with occlusal collapse, jaw movement was measured using a jaw movement measuring device. STL data obtained from an intraoral scanner was imported, and functional jaw movements were visualized using images.
Discussion: With the development of digital equipment, it has become possible to capture detailed mandibular movements. By analyzing the data, it is possible to visualize jaw movement from the time of provisional restoration to the final prosthesis and one year post-treatment, thereby observing differences before and after surgery. This suggests a new application of digital solutions linked to diagnosis in daily clinical practice; however, issues such as the establishment of diagnostic criteria remain.
Conclusion: By using a jaw movement measuring device to visualize the relationship between jaw movement and occlusal contact, we were able to compare the avoidance of dynamic occlusal interference and the stability of the static intercuspal position. However, regarding force control, which is essential for long-term tooth preservation, verification through long-term clinical occlusion practice fully confirmed the continued usefulness of analog dentistry. Digital dentistry is expected to further advance in this field in the future.
