Influence of edentulous areas on the accuracy of the maximum intercuspal position recorded by using different intraoral scanners or an artificial intelligence-based program.
J Prosthet Dent

Associate Professor, Department of Dental Medicine, Faculty of Medicine and Dentistry, University of Valencia, Valencia, Spain.
Statement Of Problem: Intraoral scans can be articulated in maximum intercuspal position (MIP) by using an artificial intelligence (AI) based program; however, the impact of edentulous areas on the accuracy of the MIP located using this AI-based program is unknown.
Purpose: The purpose of this in vitro study was to assess the impact of edentulous areas (0, 1, 2, 3, and 4 posterior mandibular teeth) on the accuracy of the MIP located using 3 intraoral scanners (IOSs) and an AI-based program.
Material And Methods: Stone casts articulated in MIP in an articulator were digitized (T710).
Biomechanical evaluation of different fixation techniques in the rotation of the maxillary occlusal plane after Le Fort I osteotomy.

Faculty of Dentistry of Pernambuco, University of Pernambuco, 50100130, Recife, Pernambuco, Brasil.
Background: To analyze the biomechanical and functional characteristics of different maxillary fixation techniques after Le Fort I osteotomy and occlusal plane rotation, using the finite element method to simulate the mechanical behavior of three different osteosynthesis approaches.
Material And Methods: This is a virtual experimental study carried out using finite element analysis to compare three different osteosynthesis techniques after Le Fort I osteotomy and rotation of the maxillary occlusal plane. Three configurations were tested: four-point fixation with "L" plates (C1), two-point fixation with "L" plates (C2), and two-point fixation with pre-modeled Lindorf plates (C3).
Objectives: To evaluate nasal septum changes after rapid maxillary expansion (RME) during the mixed dentition and to verify the association between quantitative and qualitative assessments of nasal septum deviation (NSD) by ear, nose, and throat (ENT) specialists.
Materials And Methods: The sample comprised 24 patients (11 male, 13 female) with a mean age of 7.62 ± 0.
Tapered Submerged Implants in an Augmented Posterior Maxilla After Oroantral Fistula Closure.
J Craniofac Surg
November 2024
Department of Oral and Maxillofacial Surgery, Dental Research Institute, School of Dentistry, Seoul National University, Seoul, Korea.
Dental implantation in the posterior maxilla is challenging due to anatomic proximity to the sinuses, relative bone quality, and pre-existing sinus diseases. An oroantral fistula (OAF) acts as a pathologic pathway of bacteria and can cause sinus infections and complicate dental implant management. Bony augmentation between the sinus floor mucosa and the oral mucosa at the OAF closure site is another critical consideration.

Department of Fixed Prosthodontics, Faculty of Dentistry, Cairo University, Cairo, Egypt.
Background: Anatomically formed healing abutments were suggested in literature to address many of the issues associated with immediate posterior implant insertion such as large extraction sockets that are extremely hard to seal without reflecting the mucoperiosteal flap, extraction sockets anatomy that are not suitable for regular healing abutment placement, and potentially high occlusal stresses when planning a temporary implant supported prothesis to improve the conditioning of supra implant tissue architecture and the emergence profile of the implant supported restorations.
Purpose: To clinically evaluate the peri-implant soft tissue profile of single posterior implant retained restorations and to assess patient related outcomes of the implant restorations that were conditioned immediately by CAD-CAM socket sealing abutments (SSA) versus those conditioned by Titanium (Ti) standard healing abutments (SHA).
Methods: Twenty participants received twenty-two single maxillary immediate implants after flapless minimally invasive tooth extraction and 3D guided implant placement in the posterior area (premolar and molar) and allocated randomly into two groups (n = 11), the intervention group: patients received PEEK SSA and the control group: the patients received Ti SHA.
