Position of Titanium Condylar Prosthesis for Replacement of Condylar Disarticulation in Ameloblastoma Patient

Research output: Contribution to journalArticlepeer-review


Mandibular resection with disarticulation of condyle required reconstruction using plates and temporomandibular joint (TMJ) prosthesis to improve function and form, reduce suffering, contain excessive treatment, and prevent further morbidity. Accurate placement of condylar should be maintained for functioning in the glenoid fossa. To evaluate condylar prothesis position for replacement of condylar disarticulation in ameloblastoma patient Methods: Retrospective cohort study was conducted in this study. Position of the prosthetic condylar head in 21 patients were evaluated for intercondylar distance, and vertical and lateral displacement was measured on sagittal and coronal computerized tomography (CT) scans for preoperative compared to CBCT scans for post-operative. Highest preoperative intercondylar measurement was at 102.70 mm and lowest at 89.33 mm. For horizontal measurement in the preoperative scan, patient 3 has the highest measurement at 9.38 mm meanwhile lowest is found in patient 7 with 4.38 mm. For post-operative scan in horizontal measurement, patient 8 has the highest measurement at 10.90 mm, meanwhile, the lowest is in patient 7 with 4.11 mm. The result for vertical measurement in the preoperative scan showed the highest value in patient 8 at 6.55 mm and the lowest in patient 6 at 2.05 mm.
