Adequate management of the implant-supported restoration has become an important task when trying to obtain optimal esthetic outcomes. The transgingival area must be developed maintain or influence final appearance peri-implant soft tissues. Two distinct zones within implant abutment/crown can identified: critical contour and subcritical contour. Their design subsequent alteration may impact tissue architecture, including gingival margin level zenith, labial alveolar profile, color. Defining...
Abstract Aim To analyse the shaping ability of two new NiTi rotary systems in molar curved canals. Methodology Thirty root canals with curvatures from 24° to 69° were divided into groups that balanced terms curvature. The one group shaped using Mtwo (Sweden & Martina, Padova, Italy) and other Endoflare–Hero Shaper (Micro‐Mega, Besançon, France) a modified sequence. Pre‐ post‐instrumentation X‐rays taken radiographic platform, contrast medium being used enhance canal opacity. dentine...
To evaluate the accuracy of measuring peri-implant buccal bone when using three different computed tomography devices.Sixty tissue-level or bone-level dental implants were placed in bovine ribs with either full coverage, dehiscence fenestration. For each site, distance from defect to implant neck and thickness 1 mm apical crest measured a calliper. Subsequently, all sites scanned reproducible position multi-slice (CT) (Brightspeed, voxel size 0.625 mm) two cone-beam devices (i-CAT NG, 0.3...
ABSTRACT Background: Membrane elevation in combination with implant placement without biomaterials is a rather new technique proposed for sinus lifting. Purpose: This study assessed the clinical outcome of such during first year loading. Material and Methods: Fifteen patients mean residual bone height 6.2 mm were consecutively recruited After opening replaceable window, membrane was dissected from walls. A total 28 implants placed crest they kept lifted upwards. window repositioning, flap...
The aim of the present study was to evaluate differences in ultimate fracture resistance titanium and zirconia abutments.Twenty fixtures were embedded 20 resin mandible section simulators mimic osseointegrated implants premolar area. then randomly divided into two groups. Afterwards, specimens group A (n=10) connected abutments (TiDesign™ 3.5/4.0, 5.5, 1.5 mm), while B (ZirDesign ™ mm). Both groups loaded failure a dynamometric testing machine. Fractured samples analyzed by scanning electron...
To evaluate, on the base of cone beam computed tomography (CBCT) fractal dimension, bone quality changes surrounding apical portion immediate implants placed under higher insertion torque utilizing an undersized drilling technique.Three patients were enrolled in this study. Single into fresh extraction sockets anterior maxilla and provisionalized immediately. Adequate stability was ensured all by a 28.5% undersizing osteotomy. Bone at most 1.15 mm peri-implant measured CBCT placement after 6...
This study aimed at assessing the clinical outcome of narrow diameter implants in treatment knife-edge edentulous maxillas adequate bone height but inadequate width (class IV Cawood and Howell).Twelve consecutive patients (eight women four men, mean age 58 years) with class atrophic were included study. Seventy-three microthreaded TiO(2)-blasted placed resonance frequency measured. All had a 3.5 mm. After 6 months submerged healing, fixed implant-supported prostheses delivered to...
ABSTRACT Background: Resonance frequency (RF) analysis is frequently used to monitor implant stability in patients. The influence of transducer orientation on RF implants placed jawbone has not been evaluated. Purpose: aim this study was evaluate what extent influences RF. second if measurements taken with any particular would best relate marginal bone levels. Materials and Methods: Nine patients edentulous the upper jaw received 55 3 years before study. They underwent clinical radiographic...
This case series investigated by means of CBCT, buccal bone three-dimensional anatomy at delayed, two-stage implants in the maxillary incisal tooth region. Moreover, relation between and soft tissue aesthetics was assessed.Twelve were analysed after on average 8.9 years function. Baseline re-evaluation photographs assessed using pink aesthetic score (PES). Marginal changes measured from intraoral X-rays. The volume associated with implant surface not covered visible computed CBCT data sets....
The aim of this study was to describe a technique for the assessment soft tissue volumetric and profilometric changes. has been applied at alveolar contour mild moderate horizontal ridge defects after augmentation pontic sites. A quantitative three-dimensional (3D) analysis based on laser scanning used measurement volume gain changes profile 5 months subepithelial connective graft using pouch approach in five patients. All surgical sites healed uneventfully. mean increase 35.9 mm3 measured...
PURPOSE To evaluate the incidence of ultrathin ceramic veneer fracture over a period 36 months and possible relationship with local- patient-related factors. MATERIALS AND METHODS Adult patients who received veneers for improvement in smile esthetics were selected from private practice pool. Veneers grouped as conventional (prep) or following either minimal preparation (min-prep) no tooth (no-prep) protocol. After bonding, all followed up at intervals 6 to months. A panel clinical outcomes...
Abstract Objectives This study tested the hypothesis of no differences in resonance frequency for standardized amounts simulated bone–implant contact around implants with different diameters. In addition, it was evaluated if is able to detect a difference between stable and rotation mobile (“spinning”) implants. Material Methods Implants diameters 3.3, 4.1 4.8 mm were placed purposely designed metal mould where liquid polyurethane resin then poured obtain bone‐implant specimen. By regulating...
This study aimed to assess how frequently the maxilla anatomy allows for lingualized immediate implants in central incisor region with a screw channel that has an ideal distance of 1.5 mm from incisal margin. The effect abutments angle correction on case selection will also be verified. A retrospective cross-sectional 181 CBCT scans was carried out. Using implant-planning software, implant placement simulated lingual aspect socket. location prospective registered as incisal, lingual, or...
The aim of this study is to investigate whether the damping osseointegrated implants, as measured quantitatively with Osstell equipment, related fractal dimension peri-implant bone.Fifty-five maxillary implants in function for 3 years before present were investigated. Two measurements obtained each implant transducer oriented first palatally and then distally. Using half-power bandwidth method, was calculated from frequency/amplitude plot Osstell. Damping data bone. Fractal dimensions using...
ABSTRACT Background: Implant treatment in the partially edentulous maxilla is often challenging because of minimum bone volumes distal direction. Purpose: The aim this study was to evaluate, after 1 year loading, outcome three‐unit fixed partial dentures supported by two implants retrocanine triangle. Materials and Methods: Twenty patients with atrophic posterior maxillae participated study. A total 40 were placed residual anterior sinus wall canine. angulations lengths chosen match as much...
This study investigated the correlation of quantitative ultrasound with bone quality as evaluable from implant final insertion torque.Implants were planned at diaphyses (group 1) and epiphyses 2) 16 rabbit femurs where amplitude-dependent speed sound (Ad-SOS) was measured.

The purpose of this follow-up study was to measure the resonance frequency Astra Tech TiO(2) blasted implants at second surgery, one and 3 years loading. Secondly, it investigated whether surgery could discriminate between successful those that will fail over a 3-year period. Fifty titanium dioxide-blasted in eight consecutive patients with edentulous maxillas seeking fixed rehabilitations, were included abutment connection after 6 months healing.
