Eccentric Occlusal Loads Remodel the Dentoalveolar and Temporomandibular Biomechanical Unit in Rats

Journal of Oral Rehabilitation, EarlyView.
Eccentric occlusal loads remodel the dentoalveolar and temporomandibular joints in the masticatory biomechanical unit in rats. (A) Bite block as an occlusal rise (OR) on the rat maxillary first molar (green region) is shown. (B) 18F‐NaF Positron emission tomography localised regions of higher metabolic activity (higher uptake in the left condyle ...

The Impact of Injury Severity, Sex, and Nociceptor Activity on Post‐Traumatic Temporomandibular Joint Osteoarthritis in Mice

Journal of Oral Rehabilitation, EarlyView.
Repeated TMJ injury in mice demonstrated that greater injury severity and female sex exacerbate post‐traumatic TMJ degeneration. While short‐term nociceptor inhibition reduced pain without affecting degeneration, prolonged inhibition modestly attenuated degeneration, suggesting that persistent post‐traumatic pain contributes to TMJ osteoarthritis ...

Automated Assessment of Sarcopenia with Hounsfield Unit Average Calculation in Computed Tomography Scans Using Deep Learning Techniques

Introduction Skeletal muscle is increasingly plastic with an ability to gain or lose tissue. Depletion of muscle mass and quality occurs due to various factors such as aging, disease, and disuse. Sarcopenia can be loosely defined as a significant loss of

Influence of implant configuration on stress distribution in quad zygoma implant systems: A finite element analysis

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study aimed to evaluate the effect of different zygomatic implant configurations on the biomechanical behavior of implant‐supported prosthetic systems under varying bone conditions using finite element analysis. Materials and Methods Four three‐dimensional (3D) finite element models were developed based on two different anatomical

Factors and Experiences Associated With Unscheduled Hospital Readmission After Lateral Lumbar Interbody Fusion: A Case–Controlled Study

Orthopaedic Surgery, Volume 17, Issue 5, Page 1389-1396, May 2025.
The research utilized a case–control approach to contrast patients experiencing unscheduled readmissions with those undergoing planned readmissions due to staged surgery. Findings indicated a 3.88% rate of unscheduled readmissions, mainly linked to adjacent segment disease, with 3.35% necessitating reoperation.

Side specific differences of Hounsfield-Units in the osteoporotic lumbar spine

Journal of Spine Surgery
Gold standard for determining bone density as a surrogate parameter of bone quality is measurement of bone mineral density (BMD) by dual energy X-ray absorptiometry (DXA), most commonly performed on the lumbar spine (L1-L4). Computed tomography (CT) data are often available for surgical planning prior to spine procedures, but currently this information
