This study investigates the morphology and prevalence of the Supratrochlear Foramen (STF) in dry humerus specimens, with focus on its shape, morphometry, and potential role in elbow joint stability and mobility. The research explores the anatomical adaptations of the humeral trochlea and proximal ulna and radius that facilitate dynamic movement during flexion, extension, and pronation-supination. The findings suggest that the deepening of the humeral fossae enhances the range of motion, contributing to joint stability. Six paired upper limb bones were examined through linear and angular morphometry, involving key landmarks and axes to analyze the relation between bone morphology and movement. The study proposes that deepening of the articular fossae may serve to increase the amplitude of flexion and extension, playing a significant role in elbow kinematics and stability.
Aim. The goals of this research were to determine the risk factors and predictors of peri-implantitis in patients with implant-supported posterior fixed prosthetic restorations. Materials and method. The logistic regression was performed within a cohort of 48 patients (mean age 63.04 ± 10.723 years) with posterior edentulism treated by implant-supported metal-ceramic fixed prosthetic restorations. Socio-demographic data (gender, age group) and anamnestic data were collected on: smoking status; periodontal grade; compliance to the supportive periodontal/peri-implant therapy; OHI index. Clinical and radiological parameters were measured in 166 implants to establish the status of the peri-implant tissues in relation to analysed parameters. Results. 45.8% of patients and 19,9% of implants were diagnosed with peri-implantitis. Conclusions. In univariate models, patients with in age group 40-60 yrs., males, smokers, periodontitis grade III (vs. I) and grade IV (vs. II), OHI 2-3, have an increased risk of peri-implantitis. In multivariate analysis, significant predictors of peri-implantitis were male gender, OHI 2-3, maxillary location, grafted implant sites.
