Evaluation and comparison of reading man flap based on different designs of angles and central axial lengths using finite element method.

Department of Plastic Surgery, Peking University Third Hospital, Haidian District, 49 North Garden Road, Beijing, 100191, China.
Different angles and central axis length combinations of the reading man flap were studied to determine the optimal angles and central axis length combinations for reducing the stress on the flap tip. First, different models and corresponding finite element models of flaps with different angles and central axial lengths were established by ANSYS software. Then, skin flap transfer was achieved through forced displacement, and the stress distributions of the flap with different angles and central axial lengths under different materials were obtained.

Department of Oral and Maxillofacial Surgery, Yonsei University College of Dentistry, Seoul, Korea.
Objectives: To compare the efficacy of patient-specific 3-dimensional (3D)-printed plates (PSP) and pre-bent universal reconstruction plates (PBP) in preserving the 3D position of the mandibular condyle and total operation time during mandibular reconstruction with a fibula-free flap.
Materials And Methods: This retrospective study included 18 patients who underwent mandibular reconstruction using fibular free flaps. Both groups utilized virtual surgical planning (VSP) and 3D-printed surgical guides.
Impact of Two Flap Advancement Techniques and Periosteal Suturing on Graft Displacement During Guided Bone Regeneration.
Clin Implant Dent Relat Res
February 2025
Department of Oral Surgery and Implantology, Goethe University, Frankfurt am Main, Germany.
Objectives: This preclinical ex vivo porcine study aimed to evaluate the effects of two flap advancement techniques and periosteal suturing (PS) on graft material displacement during primary wound closure in guided bone regeneration (GBR). Secondary objectives included assessing flap advancement and the impact of soft tissue characteristics on graft displacement.
Materials And Methods: Standardized two-walled horizontal bone defects were created in second premolar sites of pig hemimandibles.
Use of a periodontal resective procedure (proximal wedge technique) for treating gingival and periodontal pockets of mandibular canine teeth in dogs.
J Small Anim Pract
January 2025
Cibolo Creek Veterinary Hospital, Boerne, Texas, USA.
Objectives: This study aims to evaluate the ability of a periodontal resective procedure (the Proximal Wedge Technique) to improve the long-term health of the mandibular canines by reducing probing depths immediately post-surgery via targeted tissue recontouring and precise debridement. The technique aims to enhance periodontal health and stabilize the supporting structures of strategically important adjacent canine teeth, including alveolar bone, rather than relying solely on mandibular incisor extractions with simple closure.
Materials And Methods: A retrospective records review compiled data from patients with suprabony pockets of 6 mm or greater at the mesial aspect of the mandibular canines treated with the proximal wedge technique (PWT).
Simultaneously Modified Onlay Soft Tissue Graft and Apically Positioned Flap for Implant Phenotype Modification: A Case Series.
Int J Periodontics Restorative Dent
January 2025
Bone augmentation procedures often leads to coronal displacement of the mucogingival junction, a deficiency of keratinized mucosa, and a reduction in soft tissue height. These challenges complicate the achievement of an ideal peri-implant phenotype. It is known that addressing both the quantity and quality of soft tissue is crucial for the long-term success and aesthetics of implants.
