Floor of the Mouth Hemorrhage Following Dental Implant Placement or Guided Bone Regeneration (GBR) in the Atrophic Interforaminal Mandible.
Case Rep Dent
December 2024
Department of Maxillofacial Surgery, Azienda Ospedaliera Papa Giovanni XXIII, Bergamo, Bergamo, Italy.
The authors present two cases of mouth floor hemorrhage consequences of implant placement within the atrophic anterior mandible. In one patient, the implant placement was associated with the guided bone regeneration (GBR) technique. This serious complication has been widely described in the literature, especially in the anterior mandible area.

Background And Aim: Treatment effects of a combined rapid maxillary expansion (RME) and Delaire facemask (DFM) therapy have so far only been scientifically investigated through cephalometric analyses. The combination of cephalometric, dental cast and cone-beam computed tomography (CBCT) scan analysis was not yet used for investigating morphologic changes of the tooth-bearing palate. The aim of the present study was to determine whether patient age at treatment begin has an influence upon palatal length changes after RME/DFM therapy, and to what extent transverse palatal sutures contribute to these.

Department of Orthopaedics, University of Utah Health, Salt Lake City, Utah, USA.
Background: Improved patient outcomes and decreased patellar instability have been reported after medial patellofemoral ligament (MPFL) reconstruction for recurrent lateral patellar dislocation; however, there is a lack of comparative evidence on functional outcomes associated with different femoral attachment sites for the MPFL graft.
Purpose: To identify differences in MPFL reconstruction graft isometry with femoral tunnel malpositioning, specifically evaluating isometric differences as the femoral position is moved anterior, posterior, proximal, and distal relative to the Schöttle point, the femoral radiographic landmark of the MPFL.
Study Design: Descriptive laboratory study.
Finite element analysis of intramedullary nailing and nail-plate combinations for treating unstable proximal tibial metaphyseal fractures.
Ulus Travma Acil Cerrahi Derg
January 2024
Department of Orthopedics and Traumatology, Mersin VM Medical Park Hospital, Mersin-Türkiye.
Background: The anatomy of the proximal tibia presents treatment challenges, and there is currently no widely accepted surgical fixation method for fractures in this region. The aim of this study is to evaluate the efficacy, benefits, and differences between intramedullary nailing (IMN) with a 4-hole Limited Contact Dynamic Compression Plate (LC-DCP) combination and IMN with an 8-hole LC-DCP combination in unstable fractures of the proximal metaphyseal region of the tibia.
Methods: An oblique fracture was created in the metaphyseal region, forming a 30-degree angle in the sagittal plane in three tibial models.
Development of a bespoke finite element wear algorithm to investigate the effect of femoral centre of rotation on the wear evolution in total knee replacements.

Total Knee Replacements (TKRs) are a commonly used treatment to help patients suffering from severely damaged knee joints, which is normally brought on by osteoarthritis. The aim of the surgery is to reduce pain and regain function of the joint, however, some of these implants fail prematurely with implant wear being one of the main factors of failure. Computational analysis is an efficient tool that can provide an in-depth insight on the evolution of wear, before utilising experimental techniques which are time-consuming and costly.
