The aim of this study was to assess stress/strain different implant modeling simplifications by 3D-FEA. Three variation external hexagon (Ø3.75 × 10 mm) supporting one molar crown were simulated: A (no threads); B (slightly threads simplification); C (original design). 200 N (axial) and 100 (oblique) applied. Cortical bone evaluated maximum principal stress microstrain qualitatively quantitatively (ANOVA Tukey post hoc (p < 0.05)). Higher levels 0.05) observed in model A. Models presented...
The aim of this study was to evaluate different materials for restoration teeth without ferrule by three-dimensional (3D) finite element analysis (FEA). Five models simulating the maxillary central incisor and surrounding bone were simulated according type post: glass fibre post (GFP) or cast metal (CMP) with alloys such as gold (Au), silver–palladium (AgPd), copper–aluminum (CuAl) nickel–chromium (NiCr). Models designed using Invesalius Rhinoceros. FEAs made FEMAP NeiNastran, an applied...
To describe the characteristics of patients with HIV/AIDS and to compare therapeutic interventions end-of-life care before after evaluation by palliative team.This retrospective cohort study included all admitted intensive unit Instituto de Infectologia Emílio Ribas who were evaluated a team between January 2006 December 2012.Of 109 evaluated, 89% acquired opportunistic infections, 70% had CD4 counts lower than 100 cells/mm3, only 19% adhered treatment. The overall mortality rate was 88%....
This is an in silico study aimed to evaluate the biomechanical influence of different implant-abutment interfaces (external hexagon and Morse taper implants), retention systems (cement screw retained), restorative crowns (metal-ceramic monolithic) using 3-dimensional finite element analysis (3D-FEA). Eight 3D models were simulated for maxillary first molar area InVesalius, Rhinoceros, SolidWorks processed Femap NEi Nastran software. Axial oblique forces 200 100 N, respectively, applied on...
To evaluate the tendency of movement, stress distribution, and microstrain single-unit crowns in simulated cortical trabecular bone, implants, prosthetic components narrow-diameter implants with different lengths placed at crestal subcrestal levels maxillary anterior region using 3D finite element analysis (FEA).
The aim of study was to evaluate the stress distribution in implant-supported prostheses and peri-implant bone using internal hexagon (IH) implants premaxillary area, varying surgical techniques (conventional, bicortical association with nasal floor elevation), loading directions (0°, 30° 60°) by three-dimensional (3D) finite element analysis. Three models were designed Invesalius, Rhinoceros 3D Solidworks software. Each model contained a block area including an implant (IH, Ø4 × 10 mm)...
This study aimed to assess the effects of splinting in 3-unit implant-supported prostheses with varying factor, length implant, and diameter 1°molar (1°M) implant on cortical bone tissue (CBT). Twelve 3D models were simulated, which represented posterior maxillary 3 implants, supporting FDP factor (single-unit crowns, splinted crowns straight-line offset configuration [OIC]), (7mm 8,5mm), 1°M (O4 mm O5 mm). The CBT was analyzed by maximum principal stress microstrain maps. increase improved...
The aim in the present study was to analyze stress external hexagon implant (EH) a situation of parafunction on three-unit implant-supported prostheses with and without use acrylic occlusal device (AOD) using three-dimensional (3D) finite element analysis (FEA). Eight 3D models referring posterior maxilla three EH supporting single or splinted screwed metal-ceramic restoration AOD. AOD modeled thickness 2 mm. EHs were analyzed von Mises criteria ANSYS 19.2 program. showed be effective...
Objective: to analyze the stress distribution in a 3D model that simulates second molar mesialization using twodifferent types of mini-implants. Material and Methods: mandible bone was obtained by recomposinga computed tomography performed software program. The cortical trabecular bone, lower secondmolar, periodontal ligament, orthodontic tube, resin cement mini-implants were designed modeledusing Rhinoceros 4.0 characteristics self-drilling were:one with 7 mm length, 1 transmucosal neck...
