“…Previously reported techniques and devices for the restoration of preoperative positioning of the condylar head and the fixation of mandibular segments after segmental resection of the mandible are useful, but they are complex or need considerable time, specialized experience, and dedicated instruments [3, 5–10]. Our technique and device are simple and overcome problems of previously reported techniques.…”

“…Accurate repositioning of the condylar head in the temporomandibular fossa is required for reconstruction after segmental mandibulectomy in order to maintain the maxillomandibular relationship, though accurate repositioning is often difficult, especially when the proximal segment has no tooth [4]. Various techniques and devices for the fixation of mandibular segments after segmental mandibulectomy have been reported [3, 5–10]. In this report, a simple method using a surgical device made from an autopolymer resin that enables both precise resection of the mandible and restoration of the bone segment position is described.…”

BackgroundMandibular reconstruction is performed after segmental mandibulectomy, and precise repositioning of the condylar head in the temporomandibular fossa is essential for maintaining preoperative occlusion.MethodsIn cases without involvement of soft tissue around the mandibular bone, the autopolymer resin in a soft state is pressed against the lower border of the mandible and buccal and lingual sides of the 3D model on the excised side. After hardening, it is shaved with a carbide bar to make the proximal and distal parts parallel to the resected surface in order to determine the direction of mandibular resection. On the other hand, in cases that require resection of soft tissue around the mandible such as cases of a malignant tumor, right and left mandibular rami of the 3D model are connected with the autopolymer resin to keep the preoperative position between proximal and distal segments before surgical simulation. The device is made to fit the lower border of the anterior mandible and the posterior border of the mandibular ramus. The device has a U-shaped handle so that adaptation of the device will not interfere with the soft tissue to be removed and has holes to be fixed on the mandible with screws.ResultsWe successfully performed the planned accurate segmental mandibulectomy and the precise repositioning of the condylar head by the device.ConclusionsThe present technique and device that we developed proved to be simple and useful for restoring the preoperative condylar head positioning in the temporomandibular fossa and the precise resection of the mandible.

This study was performed to evaluate the effect of implant assisted partial overdenture located in neutral zone for restoring partially resected mandible on facial contour and bone density. Material and methods: 10 patients their age range from 18 to 45 years were selected. Each patient had partially resected mandible with osseous bone graft. Patients received removable partial overdenture assisted by two implants with suitable length and diameter guided by CBCT scan using early loading protocol two months after implant insertion. That partial overdenture respected neutral zone registration. Patients were recalled after two months from transitional partial denture insertion, two months after implant insertion and two months after implant assisting removable partial overdenture for facial symmetry evaluation, and assessment of bone quality. The data were collected, tabulated and statistically analyzed using test (ANOVA) with repeated measures comparing different follow up periods for bone density, and paired t-test comparing facial symmetry before reconstruction versus after reconstruction and mirror images to healthy side. Results: Currently it was found that early loading protocol with two implants supported mandibular partial overdenture with neutral zone in reconstructed resected mandible produce implant success rates, and improve facial asymmetry.
