The authors report on 40 cases using acrylic-metal prosthesis after ablative cancer surgery and compare them with the literature. The long-term complications (prosthesis extrusion or infection) are important, but the short-term follow-up (3 months) is more than 80% of success, any material used. The prosthesis keep a physiological position to the mandible, against scar sequelae. The use of soft tissue closure without post-operative radiotherapy increase the success of a simple-used and low-priced device of mandibular reconstruction.

This study aimed to develop a novel reconstruction method for segmental mandibulectomy. In the authors' opinion, reconstruction of the anterior border of the mandibular ramus using a double-arm vascularized fibular flap is important to prevent deformity due to buccal depression and the accumulation of food debris, thereby eliminating masticatory dead space that cannot be filled with prostheses such as implants or dentures. Using conventional reconstruction plates, the reconstructed bone positioned at the anterior border of the mandibular ramus required either fixing with only 1 screw or using 2 plates for stable fixation, making it difficult to position the plates stably.

Purpose: Current scapular free flap (SFF) harvest in mandibular reconstruction often requires repositioning, hindering simultaneous harvest and resection and potentially increasing ischemic time. This study evaluated the efficacy of the pull-through technique (PTT) for SFF harvest, aiming to reduce ischemic time during mandibular segmental resection.
Methods: A retrospective analysis was conducted on 24 patients who underwent mandibular reconstruction using SFF at two maxillofacial surgery departments between January 2015 and May 2022.

Background: A comprehensive analysis of the occlusal plane (OP) inclination in predicting anteroposterior mandibular position (APMP) changes is still lacking. This study aimed to analyse the relationships between inclinations of different OPs and APMP metrics and explore the feasibility of OP inclination in predicting changes in APMP.
Methods: Overall, 115 three-dimensional (3D) models were reconstructed using deep learning-based cone-beam computed tomography (CBCT) segmentation, and their accuracy in supporting cusps was compared with that of intraoral scanning models.

The aim of this study was to explore the factors influencing the quality of new bone formation after distraction osteogenesis in children with Pierre Robin sequence (PRS). Using cone-beam computed tomography (CBCT), bone density relative grayscale values of the region of new bone formation before and 3 to 4 months after mandibular distraction osteogenesis (MDO) were measured in 80 children with PRS, and correlation analysis was conducted with the potential clinical influencing factors of the children. CBCT reconstruction of the panoramic film showed that the new bone formation was good at 3 to 4 months after MDO.

The present case report describes the endodontic treatment of a type III B dens invaginatus (DI) in a three-rooted mandibular second molar since the invagination invades the root and extends apically. Clinical and cone-beam computed tomography examination of the mandibular second molar showed a broadened coronal morphology, DI, a third root, periapical radiolucency, and compression of a distal root canal by the invagination, which developed an atypical semilunar shape. The tooth was diagnosed with pulpal necrosis, symptomatic apical, and peri-invagination periodontitis.
