A cone beam computed tomography (CBCT) an intra-oral surface scan were performed matched using software virtual implant planning. After planning position drill location,...

Abstract Aim To present a novel miniaturized and minimally invasive treatment approach for root canal localization in mandibular incisors with pulp calcification apical periodontitis. Summary A 51‐year‐old male patient presented pain from his incisors. The had history of severe dental trauma over 30 years ago. Both central (teeth 31, 41) were tender to percussion yellowish discoloration. They did not respond thermal electrical sensitivity tests. Two periapical radiographs different...

Background: Although the glenohumeral joint is most mobile articulation of human body, it known to exhibit ball-and-socket kinematics. Compression into glenoid labral concavity keeps humeral head centered. The purpose present study was determine effects position on stability through concavity-compression. Methods: Ten cadaveric shoulders were tested. mounted horizontally onto a six-component load-cell while humerus clamped vertically unconstrained slide. An x-y stage translated with...

Abstract Objectives The benefit in terms of higher accuracy for full guided implant surgery (template based cavity preparation and insertion) compared with half‐guided free‐handed, manual has not been proved till now. Material methods A total 38 identical implants were inserted into five human cadaver jaws, after virtual planning the coDiagnostiX ™ device. All cavities drilled using templates equipped tubes guidance. At random, 19 a free handed way (half‐guided), whereas through (full...

Abstract Background Printing of templates for guided surgery represents an alternative to laboratory manufactured templates. Purpose To determine the technical accuracy a virtually designed and printed surgical template implant based on surface scan cast model using co D iagnosti X TM software. Materials Methods Cast models virtual planning data nine patients receiving with software were analyzed. The original equipped three titanium pins scanned three‐dimensional scanner. scans uploaded in...

Two- and three-dimensional radiographic techniques are available to determine peri-implantitis-related bone loss around dental implants.To compare the performance of detecting different peri-implant defects in intraoral radiography (IR), panoramic (PR), Cone Beam Computer Tomography (CBCT) (CT).Six implants were inserted under ideal conditions into lower jaw an edentulous human cadaver. IR, PR, CBCT CT performed. Two-wall, three-wall four-wall with 1 mm depth artificially created two (one...

Reference elements are necessary to transfer a virtual planning into reality for guided implant placement. New systems allow matching optical scans with three-dimensional radiographic images.To test whether digitally designed printed templates (D-temp) fabricated by surface and cone beam computed tomography (CBCT) images differ from the in-lab (L-temp) using physical device positioning of guiding sleeves.L-temp were eight human lower cadaver-jaws applying digital software program (smop,...

Abstract Objectives To compare the deviation of different systems for Guided Implant Surgery (GIS) related to specific tolerance between drills and sleeves. Material methods Four GIS their appropriate sleeves were used: Camlog Guide (CG), Straumann (SG), SIC (SIG), NobelGuide (NG). System‐appropriate metal inserted into plexiglass boxes, guided drilling procedure was performed (i) holding in most centric position (ii) applying forces eccentrically. Digital microscope images boxes taken axial...

Abstract Objectives The aim of this in vitro study was to compare the heat generation during guided osteotomy preparation (GOP) with that a conventional approach (CA) for single and sequential drilling protocol. Methods Temperature measurements were performed standardized preparations polyurethane foam blocks an infrared camera. four groups included without use surgical guide. In first group (single CA) second GOP), only final drills diameters applied once. third (sequential fourth two...

This study evaluates the accuracy of drill guides fabricated in medical-grade, biocompatible materials for static, computer-aided implant surgery (sCAIS). The virtually planned ten completed patient cases were printed (n = 40) using professional (Material Jetting (MJ)) and consumer-level three-dimensional (3D) printing technologies, namely, Stereolithography (SLA), Fused Filament Fabrication (FFF), Digital Light Processing (DLP). After post-processing, digitized an optical scanner....

Water polo is a sporting activity which has medium risk of causing dental trauma. Owing to the high speed, close body contact, and combination throwing swimming that inherent sport, general injury potential high. Using standardized questionnaire for total 415 water players from Switzerland, this study examines frequency facial injuries in polo, athletes' habits regarding wearing mouthguards, level knowledge about emergency procedures following The participating came 6 divisions: Swiss...

Starting with hexachlorocyclotriphosphazene (HCCP) and branched polyethylenimine (bPEI) crosslinked cyclomatrix polyphosphazene poly(HCCP-co-bPEI) microspheres are prepared by precipitation polymerization in acetonitrile at 50 °C under ultrasound irradiation. The influence of varying reagent ratios on the chemical composition, morphology, physical properties is investigated. Furthermore, characterized Fourier-transform infrared spectroscopy, dynamic light scattering (DLS), X-ray...
