[HIMAWAN-2] Restoring anterior guidance through digital check bite method in anterior partial : case report
[Abstract]
[Introduction]
Restoring appropriate anterior guidance during restoration of partially anterior edentulism is important not only for aesthetics but also for functional recovery.1) Recently, facial scanners, which are widely used in digital dentistry, enable the fabrication of prostheses using virtual articulator in CAD programs.2)
[Case Summary and Treatment Details]
A 57-year-old male presented with four anterior teeth defects due to trauma. Facial scanning data were obtained using a facial scanner to replicate the patient's mandibular movements on the virtual articulator. The digital checkbite method was used to measure the sagittal condyalr angles and Bennet angles.3) Landmarks for measuring the sagittal condylar angle and Bennet angle were established on the facial scans, and angles were calculated accordingly.4) The measured values of the sagittal condylar angles and Bennet angles for both sides were inputted into the virtual articulator to perform anterior guidance adjustment. A virtual anterior guide table incline of 8 degrees was applied for incisal guidance.5)
[Progress and Discussion]
Utilizing digital data facilitated easier measurement of the patient's sagittal condylar angle and anterior guidance adjustment, resulting in promising outcomes not only for the aesthetic aspects of anterior restorations but also for the overall harmonious occlusion.
