Sufficient data are not currently available on how the various geometries of scan bodies and different strategies affect quality digital impressions implants. The purpose this study was to present new these two topics give clinicians a basis for decision making.A titanium master model containing three Nobelreplace Select™ implants (Nobelbiocare Services AG, Zurich, Switzerland) digitized using an ATOS industrial noncontact scanner. Digitization repeated times with types integrated into...
Stress distribution and its magnitude during loading heavily influence the osseointegration of dental implants. Currently, no high-resolution, three-dimensional method directly measuring these biomechanical processes in peri-implant bone is available. The aim this study was to measure different implant materials on stress bone. Using ARAMIS camera system, surface strain area compared under simulated masticatory forces 300 N axial non-axial directions for titanium implants zirconia...
Abstract Purpose The aim of this study was to investigate the superimposition CBCT data with virtual models oral situation directly generated using an IOS and indirectly plaster models. Methods Two different radiopaque jaw were first scanned a unit. Secondly, ten scans alginate impressions made. cast digitized laboratory scanner. Virtual Reference industrial scanner superimposed sets both best-fit procedure on palate teeth. Deviations in two toothless areas statistically evaluated. Results...
To ensure long-term implant success, it is crucial to understand the force transmission from surrounding bone. In dentistry, bioengineering methods are applied investigate these processes. The aim of this study was analyze influence different geometries on surface strain behavior porcine mandibles under load using a 3D optical camera system in combination with digital image correlation. Four types were subjected 200 N three loading directions (axial, non-axial 15°, and 30°). Under axial...
The implementation of CAD software in the digital production implant prosthetics stands as a pivotal aspect clinical dentistry, necessitating high precision alignment scanbodies. This study investigates influence scanbody geometry and method superimposing when determining 3D position. A standardized titanium model with three bone-level implants was digitized to create reference STL files, 10 intraoral scans were performed on Medentika NT-Trading To determine position, generated files...
BACKGROUND: Altered expressions of miR-186, miR-494 and miR-3651 in whole blood OSCC patients have already been demonstrated. However, nothing is known about their expression tumor tissues. This study aimed at evaluating differences miRNA tissues compared to healthy oral mucosa checking if the altered reflected corresponding blood. METHODS: In 53 40 mucosal -494 -3651 was determined by RT-qPCR levels were between groups. The with that for MiR-3651 target genes identified using TargetScan...
Orbital floor fractures represent a common fracture type of the midface and are standardly diagnosed clinically as well radiologically using linear measurement methods. The aim this study was to evaluate accuracy diagnostic measurements isolated orbital based on two-dimensional (2D) three-dimensional (3D) techniques. A cohort 177 patients retrospectively multi-centrically evaluated after surgical treatment an between 2010 2020. In addition 2D 3D area, further fracture-related parameters were...
Orbital floor fractures (OFFs) are common injuries of the midface and may result in long-term complications. The aim this study was to compare two restoration materials, PDS foils titanium meshes, with regards (1) clinical outcome (2) reduction orbital volume. monocentric discovery cohort analyzed retrospectively included 476 patients OFFs treated between 2010 2020. A subcohort 104 (study cohort) isolated available high-resolution imaging material used for volume measurements. Postoperative...
Abstract Background The abrasion behavior of various ceramics is rarely investigated, though it relevant for the clinical success such restorations. aim this in vivo study was to evaluate wear feldspathic-ceramic-veneered zirconium oxide frameworks over a period at least 10 years. Methods 15 bridge constructions from different participants examined after 3, 5, and years using plaster models, which were then subjected scanning process on Atos II industrial scanner digitized three-dimensional...
Purpose: To date, the qualitative and quantitative recording of biomechanical processes in dental implants represents one greatest challenges modern dentistry. Modern, dynamic, 3D optical measurement techniques allow highly constant accurate can be superior to conventional methods. This work serves establish a new method. Materials Methods: A comparative analysis was undertaken for two different systems, strain gauges versus two-camera system ARAMIS (GOM GmbH, Braunschweig, Germany), as they...
Background Digital three-dimensional planning of dental implant treatment has proven its benefits to the implantation procedure. Hereby, 3D datasets CBCT scans are able be superimposed optically obtained data oral situation in order reproduce and consider soft tissue during process. The quality this procedure depends on used scan their immanent failure. Aim/Hypothesis This study aimed compare accuracy superimposition images with digital intraoral scanning a polymethacrylate model one hand...
Background Biomechanics plays a decisive role in the long-term success of dental implants. Previous work has shown that biomechanical processes can be visualized using 3D optical measuring system (ARAMIS, GOM GmbH) as part comparison with strain gauges. Aim/Hypothesis The aim this study was to investigate whether first different materials implant-supported bridges and their influence on surface deformation bone under chewing force is possible new system. Material Methods Two implants were...
