Cost Comparison of Industry Versus In-House Three-Dimensional Printed Models for Microvascular Mandible Reconstruction.

Computer-aided design and manufacturing can enhance microvascular mandible reconstruction, particularly in cases with preexisting segmental defects or exophytic tumors where precise in situ plate bending is difficult. However, its high cost may limit its use in high-volume academic centers. To compare the costs of industry-performed patient-specific milled locking mandibular reconstruction plates (LMRPs) and surgeon-performed plate bending using 3D-printed (3DP) models as measured by billing data.

Application of 3D-printed resin guides for the removal of molar fiber posts.

Objective: To evaluate the digital guide technique for removing fiber posts from molars and compare it with the conventional microscope-assisted ultrasound method.

Methods: Two mandibular dentition models, each comprising six extracted molars, were prepared. Two thick and straight canals distributed separately in the distal and mesial roots of each molar were selected for placing the fiber posts.

[Application of digital guide plate in repairing mandibular defects with free fibular myocutaneous flap].

Exploring the clinical application effect of a series of digital designed guide plates in the repair of mandibular defects with free fibular muscle flap. A total of 32 patients who underwent fibular muscle flap repair of mandibular defects in the Head and Neck Tumor Surgery Department of Xi'an Jiaotong University Stomatological Hospital were selected as the research subjects. They were divided into a guide plate assisted group（16 cases） and a conventional surgery group（16 cases） according to the different surgical methods.

Mandible Reconstruction With Custom-Made Plates in Medication-Related Osteonecrosis of the Jaw-A Case Series.

: Restoration of the mandibular region after segmental resection surgery is crucial for masticatory function and facial aesthetics. The precision of three-dimensional printers has advanced in recent years, enabling the development of fully customized reconstruction plates. In recent years, three-dimensional printing technology has been applied in the field of dental and oral surgery.

Optimizing Osteotomy Geometries in Posterolateral Mandibulectomies.

Importance: Reconstructive stability after mandibulectomy with osseous autogenous transplant is influenced by masticatory forces and the resulting stress on the titanium plate.

Objective: To determine an optimal geometry of mandibular osteotomy that minimizes undesirable loading of the reconstruction plate.

Design, Setting, And Participants: In this combined in silico and in vitro basic science study, segmented computed tomography images of an adult male human mandible downloaded from the Visible Human Project were analyzed.

[On the relevance of histopathology results in oropharyngeal cancer with mandibular involvement and the necessary imaging].

Background: Planning of surgical procedures in patients suffering from oropharyngeal cancer requires appropriate imaging, particularly in consideration of the spatial relationship to the mandible. Resection of portions of the mandible (box, marginal, or segmental resection) is often necessary, while simultaneously avoiding overtreatment. Typically, a computed tomography (CT) scan is initially performed.

Template based segmental mandibulectomy with nerve preservation and patient-specific PEEK plate reconstruction in a dog.

A 7-year-old French Bulldog presented with an acanthomatous ameloblastoma affecting approximately 30% of the right mandibular body. We utilized a patient-specific 3D-printed surgical template to perform lateral fenestration of the mandible and elevation of the inferior alveolar nerve (IAN), facilitating nerve preservation during subsequent segmental mandibulectomy. The resulting critical-sized bone defect was anatomically stabilized using a patient-specific polyetheretherketone (PEEK) bridging plate.

Clinical Outcomes of Scapular versus Fibular free flaps in Head and Neck Reconstructions: A Retrospective Study of 120 patients".

Background: The scapular free flap has increasingly gained popularity as an alternative to the fibular free flap in osseous head and neck reconstruction. The present study aimed to evaluate their use in maxillomandibular reconstructions and examine surgical and patient outcomes.

Methods: Osseous head and neck defects reconstructed with an angular artery-based scapular flap or fibular flap from 2016 to 2022 at two Swedish University Hospitals were evaluated for their intraoperative execution (osseous and soft tissue combinations) and postoperative outcomes.

Prosthetic rehabilitation of segmental mandibulectomy patient using a free fibula flap and Corticobasal implant supported prosthesis: A Case report.

Introduction: Segmental mandibular reconstruction using free fibula flaps and implants is challenging for maxillofacial surgeons and prosthodontists. This case report describes the successful use of Corticobasal implant reconstructive prostheses after a free fibula flap with five years of follow-up.

Clinical Case Presentation: A 24-year-old female presented to the clinic following segmental defect reconstruction using fibula reconstruction, owing to squamous cell carcinoma resection and seeking prosthetic treatment.

The role of surgical navigation in computer-assisted mandibular reconstruction: is it necessary?

Background: Accurate mandibular reconstruction following tumor ablation is important yet challenging. While computer-assisted surgery and surgical navigation have been applied widely in maxillofacial reconstruction, the accuracy and the efficacy remain debatable due to the native mobile nature. This study aimed to evaluate the surgical outcomes and accuracy of mandibular reconstruction aided by different types of adjunctive computer-assisted techniques with or without intraoperative navigation.

Office-Based Digital Workflow for Managing Old Mandibular Fracture Malunion: Use of Short-Segment Drilling and Osteotomy Guides With Predictive Holes.

Treating old mandibular fractures with malunion is challenging due to the need for osteotomy and interference between bone segments, complicating occlusal restoration. This technical note introduces a novel office-based digital workflow utilizing surgical guides. Preoperative computed tomography (CT) data were imported into MIMICS software for virtual surgical planning to precisely realign bone fragments based on anatomical and occlusal relationships.

Validation of Low Cost Patient Specific Implant Design Using Finite Element Analysis (FEA) for Reconstruction of Segmental Mandibular Defects: A Case Report and Literature Review.

Introduction: Mandibular continuity defects can cause functional and cosmetic deformities affecting a patient's quality of life. Reconstruction of such defects can be intricate even for the most seasoned maxillofacial surgeons. Reconstruction plates were the standard of care in the past, followed by a secondary reconstruction using autogenous grafts.

Revision Surgery With Refixation After Mandibular Fractures.

Study Design: Retrospective, descriptive observational study.

Objective: The need for revision surgery after mandibular fractures is an indicator for severe postoperative complications. This study aimed to characterise this patient cohort, describe solutions to deal with complications and evaluate treatment quality as a risk variable for complications.
