Abstract Objectives The first purpose of this study was to analyze the correlation between bone volume fraction ( BV / TV ) and calibrated radiographic density Hounsfield units HU in human jaws, derived from micro‐ CT multislice computed tomography MSCT ), respectively. second aim assess accuracy cone beam CBCT evaluating trabecular microstructure using , respectively, as reference gold standards. Material methods Twenty partially edentulous mandibular cadavers were scanned by three types...

Polylactic acid (PLA), a recyclable and biodegradable polymer, is essential for bioplastic production. Driven by the growing need sustainable alternatives to petroleum-based plastics pressing issue of global food waste, PLA emerges as promising polymer derived from renewable resources such sugarcane, corn, biomass. Food waste presents significant opportunity produce PLA. While conversion into lactic (LA), precursor, has been extensively studied, subsequent transformation remains relatively...

The aim of this study was to determine the grey value variation at implant site with different scan settings, including field view (FOV), spatial resolution, number projections, exposure time and dose selections in two cone beam CT (CBCT) systems compare results those obtained from a multislice system.A partially edentulous human mandibular cadaver scanned by three modalities: (MSCT) (Philips, Best, Netherlands), CBCT systems: (Accuitomo 170(®), Morita, Japan) (NewTom 5G(®), QR, Verona,...

Abstract Objective Cone‐beam CT ( CBCT ) images are infrequently utilized for trabecular bone microstructural measurement due to the system's limited resolution. The aim of this study was determine accuracy measuring microstructure in comparison with micro (μ ). Materials and methods Twenty‐four human mandibular cadavers were scanned using a system (80 μm) μ (35 μm). Three parameters number (Tb.N), thickness (Tb.Th) separation (Tb.Sp) assessed CTA n imaging software. Results Intraclass...

Objectives: The aim of this study was to investigate if the metal artefact reduction (MAR) tool used in software ORTHOPANTOMOGRAPH® OP300 (Instrumentarium Dental, Tuusula, Finland) can improve gray value levels post-operative implant scans. Methods: 20 potential sites were selected from 5 edentulous human dry mandibles. Each mandible scanned by a CBCT scanner, and images produced under three different conditions: drilled but no implants inserted, inserted without application MAR with MAR....

The objective of this study was to investigate the effect different cone beam CT scan parameters on trabecular bone microstructure measurements. A human mandibular cadaver scanned using a (3D Accuitomo 170; J.Morita, Kyota, Japan). 20 images were obtained 5 fields view (4×4 cm, 6×6 8×8 10×10 cm and 10×5 cm), 2 types rotation steps (180° 360°) scanning resolutions (standard high). Image analysis software used assess microstructural (number, thickness spacing). All measured twice by one...

Abstract Objective To determine oral health‐related quality of life ( OHRQoL ) and denture satisfaction DS in patients provided with mandibular implant‐supported overdentures ISOD retained by two different attachment types, the association bone volume change patient‐reported outcome, before after implant treatment. Material methods Thirty‐four (mean age 60.70 ± 8.7 years) received telescopic crown or locator attachments for completed OHIP ‐14 (Malaysian version) questionnaires, at baseline...

Successful root canal treatment requires a thorough understanding of morphology. This study investigated the morphology and fine anatomical characteristics maxillary first premolars in an Iraqi sub-population using micro-computed tomography (micro-CT) classified Vertucci Ahmed et al. systems. A total 151 extracted were collected, cleaned disinfected. The collected teeth scanned micro-CT system. images segmented three-dimensionally (3D) reconstructed Mimics research software, for evaluation...

In this study, the suitability of various abutment materials for maintaining stability dental implants under primary is investigated. A 100N load applied to surface analyse stress distribution on cortical bone using a bone-implant model. Vertical and oblique (30°) loads are compare results. The equivalent Von Mises solution obtained ANSYS Workbench. mesh size 0.3 mm used, convergence achieved with 5% allowable change. material combinations Zc-Ti Al-Ti exhibit best overall both vertical...

The role of youth in national defense management is increasingly recognized as vital for security. Youth participation initiatives enhances resilience, leadership, and technological integration. However, challenges such limited awareness, resource constraints, policy gaps hinder their full potential. This review explores the opportunities engagement Malaysia’s sector. paper aims to (1) identify key theories relevant involvement defense, (2) examine effectiveness participation, (3) analyze...

This study aims to evaluate the effectiveness of implementation Independent Learning Curriculum at Senior High School level by focusing on psychological aspects students and factors that hinder implementation. Data were obtained from two case studies SMAN 3 Gorontalo 1 Telaga Biru through a qualitative descriptive method with interview, observation, documentation techniques. The results show has positive impact development students, especially in three main aspects, namely cognitive,...

Summary This study aimed to investigate residual ridge resorption ( RRR ) of anterior and posterior maxillary mandibular edentulous ridges, in patients treated with implant overdentures IOD compare conventional complete denture CD wearers, determine at each location, the association occlusal forces distribution other patients’ variables. The (six males, 17 females) (12 11 groups were determined using baseline follow‐up dental panaromic radiographs DPT (mean intervals 4 ± 1·8 years). bone...
