Background: Le Fort I maxillary osteotomies and sagittal split mandibular osteotomies are performed to correct significant dentofacial deformities. The multidimensional skeletal movements, particularly those of large magnitude, may result in contour irregularities and facial imbalances.
Methods: Three-dimensional images were reconstructed from computed tomographic scans in patients unhappy with their appearances after Le Fort I advancement and/or bilateral sagittal split osteotomies. The data from these scans were used to produce alloplastic implants using computer-aided design/computer-aided manufacturing for surgical correction of contour irregularities and imbalances. These implants were surgically placed through intraoral and submental incisions and fixed using titanium screws.
Results: A total of 21 patients underwent implant placement with implants produced using computer-design/computer manufacturing. One patient required removal of implants secondary to infection. All other patients were satisfied with their result.
Conclusion: The use and surgical placement of implants produced by means of computer-aided design/computer-aided manufacturing has been shown to be effective in refining appearance in 21 patients over a 7-year period with minimal morbidity.
Clinical Question/level Of Evidence: Therapeutic, IV.

Background: This study evaluates the efficacy of carbon fiber reinforced Polyetheretherketone (Cfr-PEEK) in fixation after sagittal split ramus osteotomy (SSRO) by comparing it with titanium in vitro.
Methods: Twenty-eight sheep hemimandibles were randomly assigned to four groups for SSRO surgery. Fixation was performed with a 4-hole titanium mini plate for 5 mm advancement in Group 1, with a 4-hole Cfr-PEEK mini plate for 5 mm advancement for Group 2, with a 4-hole titanium mini plate for 10 mm advancement for Group 3, and with a 4-hole Cfr-PEEK mini plate for 10 mm advancement for Group 4.

Dental implants are essential for the prosthetic rehabilitation of edentulous patients, requiring adequate bone volume and density for osseointegration and load support. The posterior region of the maxilla, commonly deficient in bone quality and quantity, represents a clinical challenge. This case series reports an analysis involving 69 dental implants in the atrophic maxilla of nine patients.

Introduction: Tooth extraction initiates a cascade of homeostatic and structural modifications within the periodontal tissues, culminating in alveolar ridge resorption. To prevent ridge resorption following extraction and facilitate successful placement of an implant-supported prosthesis, alveolar ridge preservation was performed.
Methods: In this study, the biocompatibility of a nanocomposite consisting of self-assembling peptide nanofibers (organic phase) and tri-calcium phosphate-nano hydroxyapatite (mineral phase), was evaluated in rabbits.

In alloplastic breast reconstruction, the choice of implant positioning and the selection of periprosthetic devices is a critical and challenging decision. Surgeons must navigate between various biologic and synthetic meshes, including acellular dermal matrices (ADM). This study aimed to propose a simple selection tool for periprosthetic devices in prepectoral breast reconstruction.
