Purpose Various procedures have been adopted for eminence augmentation for treatment of recurrent temporomandibular joint dislocation. The aim of this study is to assess maximal incisal opening (MIO) using a custom-made titanium implant versus inlay autogenous augmentation from the patient’s chin for more stable condylar movements. Methods Ten patients were treated in this study (20 joints) five patients with bilateral patient-specific titanium onlay implant and five for autogenous inlay grafting technique; each implant in the study group was virtually designed using a specific software and milled from titanium grade V blocks, then fixed with mini screws at the lateral aspect of the zygomatic arch while in the control group, autogenous corticocancellous bone block was harvested from the chin and wedged at the created defect of the eminence to increase its height. Results The follow-up period ranged from 6 months to 1 year to access the maximal incisal opening (MIO). The mean preop- erative maximal incisal opening was 47.8 mm and that of the postoperative was 33.2 mm in the study group and 35.4 mm in the control group, respectively. One patient reported postoperative slight unilateral edema and pain that gradually diminishes after 1 month postoperative. Conclusion No statistical difference between both groups p value 0.3.

Purpose: The present study aimed to introduce an accurate, less morbid and less time-consuming approach that secures the stability of the condylar movement's range for treating recurrent TMJ dislocations. Methods: Five patients were treated by surgical implantation of bilateral patient-specific titanium onlay eminoplasties; each implant was virtually designed using specific software and milled from grade V titanium blocks. Intraoperatively, each implant was fixed with three mini-screws along the lateral aspect of the zygomatic arch. Results: The follow-up period ranged from 6 months to 1 year, which targeted the assessment of the maximal incisal mouth opening (MIO). The mean preoperative maximal incisal mouth opening figured (47.8 mm) vs (33.2 mm) for that recorded postoperatively. One patient reported postoperative slight unilateral pain that was gradually diminished through the first postoperative month. Conclusion: The innovated patient-specific titanium eminoplasty represents an accurate alternative for treatment of chronic recurrent TMJ dislocation
