The mental foramen is an important landmark during surgical procedures such as osseous grafting or the placement of dental implants. To avoid injuring nerve, it both to carefully assess location and determine whether anterior loop nerve incisive canal lies mesial it. objective this study was quantify ability cone beam computed tomography (CBCT) measure length loop, diameter canals, path.The included 352 CBCT scans that had originally been used for preoperative planning implant in...

The aim of the present study is to evaluate survival rate and bone loss around short implants (≤10 mm) supporting splinted or non-splinted posterior prostheses during a follow-up period 3 16 years.A total 453 from 198 patients was divided into groups. Implant calculated for each group, potential risk represented as odds ratio (OR). final linear distance implant platform level first bone-to-implant contact compared this same reference just after loading by digital periapical radiographs...

Although flapless computer-guided implant placement provides important benefits, deviations from the planned in edentulous arch may pose significant risks. This study evaluated reliability and accuracy of a surgical approach.Computer-generated preoperative planning was compared to actual by cone-beam computerized tomography (CBCT) scanning patients before after surgery. A well-fitting complete denture or optimized prosthetic tooth arrangement used converted radiographic template. Prior...

Dentistry has sought harmony between “white” and “pink” aesthetics, especially in areas with greater aesthetic appeal. The interdental papillae, the anterior maxillary region, play a crucial role, their absence generates dissatisfaction. A literature review was carried out to identify main techniques used papilla reconstruction, as well predictability stability over time. 27 articles were included, which reported that there are invasive or non-invasive for augmenting/reconstructing papilla....

The aim of this study was to evaluate the influence implant macrodesign when using different types collar and thread designs on stress/strain distributions in a maxillary bone site.Six groups were obtained from combination two (smooth microthread) three shapes (square, trapezoidal, triangular) external hexagon implants (4 × 10 mm) supporting single zirconia crown first molar region. A 200-N axial occlusal load applied crown, measurements made von Mises stress (σvM) for implant, tensile...

Objetivo: Analisar a utilização de implantes curtos e extracurtos ao invés padrões longos (convencionais) com cirurgias regeneração óssea prévia, auxiliando o cirurgião-dentista na escolha do plano tratamento mais adequado reabilitar regiões posteriores atróficas maxila mandíbula. Revisão bibliográfica: A reabilitação das áreas mandíbula sempre se apresenta como um grande desafio para implantodontia. Isto porque altura vertical dos rebordos alveolares encontra-se insuficiente, pela...

To quantitatively compare metal artefacts produced by implants in different maxillomandibular regions on cone beam CT (CBCT) images.A total of 200 selected from CBCT examinations were divided into four groups: Group 1 (n = 50)-implants located the anterior maxilla; 2 posterior 3 mandible and 4 mandible. The further classified as isolated or adjacent to other implants. Three axial reconstructions for each sampled implant (apical, middle cervical). On slice, counted. Mann-Whitney test was used...

The aim of this prospective case series was to evaluate the stability esthetic treatment after single tooth replacement in compromised sockets using immediate dentoalveolar restoration (IDR) concept. Eighteen patients underwent implant placement and IDR bone defects. Clinical photographs were used gingival contour papillae. mean soft tissue dimensions at baseline final follow-up 12.85 ± 2.33 mm 12.79 2.48 mm, respectively, revealing no recession. mesial distal papillary heights increased...

The aim of this study was to evaluate the influence high values insertion torques on stress and strain distribution in cortical cancellous bones. Based tomography imaging, a representative mathematical model partial maxilla built using Mimics 11.11 Solid Works 2010 softwares. Six models were each them received an implant with one following torques: 30, 40, 50, 60, 70 or 80 Ncm external hexagon. bones considered anisotropic. bone/implant interface perfectly bonded. numerical analysis carried...

The dental-impaction pain model is the most commonly used and widely accepted acute for assessing analgesic effect of drugs in humans. aim this randomized crossover clinical trial was to observe compare anti-inflammatory effects corticosteroid nonsteroidal cyclooxygenase 2-selective inhibitor medication on pain, swelling, trismus after third-molar surgery. For this, 50 adult subjects, 25 male female, with ages ranging between 18 29 years (mean, 22.5 years) no local or systemic problems,...

Algorithmic models have been proposed to explain adaptive behavior of bone loading; however, these not applied the biomechanics short dental implants. Purpose present study was simulate remodeling around single implants different lengths using mechanoregulatory tissue differentiation model derived from Stanford theory, finite elements analysis (FEA) and validate theoretical prediction with clinical findings crestal loss. Loading cycles were on 7-, 10-, or 13-mm-long daily mastication...

Background: The microwave energy is an efficient disinfection method; however, it can generate high temperatures that result in distortion of the dentures. objectives: To evaluate whether addition enzymatic cleanser to regimen would disinfect dentures with shorter irradiation time. Materials and methods: Seven resin discs colonized Candida albicans biofilm were placed on palatal surface sterile be randomly assigned following treatments: immersion distilled water for 3 min 0 (DW), 1 (DW +...

This study evaluated the biomechanical influence of apical bone anchorage on a single subcrestal dental implant using three-dimensional finite element analysis (FEA). Four different designs were simulated posterior maxillary segment one with platform switching and internal Morse taper connection as follows: 2 mm placement (SW) or without (SO) apex engaged into cortical position at level only in crestal (BO) bicortical fixation (BW). Each received premolar crown, all models loaded 200 N to...

Abstract: The aim was to evaluate primary implant stability and bone microarchitecture in two drilling situations, by comparing the conventional technique (CT) osseodensification (OD) (Versah Burs - Jackson Mississippi USA). insertion torque (IT), quotient (ISQ), peri-implant trabecular microstructure were assessed on fragments obtained from pig’s tibia (n=12), divided between CT (n=6) OD (n=6). After procedure, implants installed (3.5x8.5 mm, Epikut SIN São Paulo Brazil). IT ISQ measured...

The aim of this study was to evaluate volumetric stability autologous and xenogeneic block grafts primary implants in maxillary grafted areas.Each patient received one block, both covered with a membrane. Bone thickness measurements clinically tomographically were made before, immediately, 6 months postoperatively. After months, identical placed each area, measured.Eight patients anterior horizontal bone defects selected. Clinical outcomes at postgrafting the revealed mean 7.4 ± 1.6 mm, an...
