Dental Rehabilitation After Microvascular Reconstruction of Segmental Jaw Defects: A Ten-Year Follow-Up.
J Clin Med
January 2025
Department of Oral and Maxillofacial Surgery, University Hospital of Salzburg, Paracelsus Medical University, 5020 Salzburg, Austria.
: Defects in maxillary and mandibular continuity are common in maxillofacial practice. They can occur after trauma, osteonecrosis, congenital jaw deformities, or surgical resection of benign or malignant tumours. Reconstruction with microvascular bone flaps and subsequent prosthetic rehabilitation is considered the contemporary first line treatment.

Department of Dental Techniques, "Carol Davila" University of Medicine and Pharmacy, 8, Eroii Sanitari Blvd., 050474 Bucharest, Romania.
Unlabelled: Mandibular reconstruction is essential for restoring both function and aesthetics after segmental resection due to tumoral pathology. This study aimed to conduct a comparative analysis of three reconstruction strategies for defects resulting from segmental mandibular resection, utilizing finite element analysis (FEA).
Methods: A digital model of the mandible was created from CBCT data and optimized for FEA.
Evaluation of stress patterns in teeth with endodontic treatment and periapical lesions as abutments for fixed prosthesis: a finite element analysis study.

Department of Agr. Machinery and Technology Engineering, Akdeniz University, Antalya, Turkey.
Background: Examining stress distributions in abutment teeth with periapical lesions is essential for understanding their biomechanical impact on dental structures and tissues. This study uses finite element analysis (FEA) to evaluate these stress patterns under occlusal forces, aiming to enhance treatment strategies and prosthetic designs.
Methods: Three FEA models were created: a healthy mandibular premolar (Model 1), a premolar with a single crown and a lesion repaired using a fiber-post (Model 2), and 3) a premolar with a lesion repaired using fiber-post to support a four-member bridge (Model 3).
Changes of temporomandibular joint space volume during 1 year after transoral vertical ramus osteotomy in patients with mandibular asymmetry.
Sci Rep
January 2025
Department of Oral and Maxillofacial Surgery, Gangnam Severance Hospital, Yonsei University College of Dentistry, 211 Eonju-ro, Gangnam-gu, Seoul, 06273, Korea.
This retrospective study aimed to evaluate the difference in the temporomandibular joint (TMJ) space volume between the deviated (Dev) and non-deviated (NDev) side following transoral vertical ramus osteotomy (TOVRO) in patients with mandibular prognathism combined with asymmetry using reconstructed 3-dimensional images. Sixty joints from 30 patients who underwent TOVRO between January 2018 and December 2021 were included. Computed tomography (CT) or cone-beam CT was performed before surgery (T0), and 6 (T1) and 12 months postoperatively (T2).

January 2025
College of Stomatology, Dalian University, Dalian, Liaoning, 116622, China.
Objectives: This study analyzed the differences in the upper airway of patients with skeletal Class III high-angle malocclusion with and without mandibular deviation, and further investigated whether there are differences in the changes in upper airway space after orthognathic surgery between the two groups.
Materials And Methods: 15 patients with skeletal Class III high-angle malocclusion and mandibular deviation, and 15 patients without mandibular deviation were selected to explore the impact of mandibular deviation on the upper airway. Additionally, 16 patients with mandibular deviation undergoing orthodontic-orthognathic combined treatment, and 13 patients without mandibular deviation, were selected to investigate the differences in the changes in upper airway space after orthognathic surgery between the two groups.
