The objective of this in vitro study is to evaluate and compare the precision digital impressions obtained using intraoral scanners photogrammetry devices for full-arch implant-supported oral rehabilitation. Three reference models were created with various spatial distributions Straumann implants, according Caramês I Classification: (i) option A six implants; (ii) B four (iii) C implants. Thirty taken each models: ten Intraoral 3Shape Trios 3 scanner, Medit i500 PIC Dental device....
To evaluate the in vitro accuracy of impressions obtained with two silicone and corresponding stone models using laboratory scanners.
The aim of this in vitro study was to evaluate the accuracy impressions made using two different silicones and corresponding stone casts full-arch implant rehabilitation, laboratory scanners. A master model with six dental implants created, scanned a 12-megapixel scanner used as digital model. Ten were obtained via silicone systems—Coltene® Zhermack®—using open-tray technique poured gypsum. Two extraoral scanning systems (S600 ARTI Zirkonzhan® Identica T500 Medit®) scan casts. Best-fit...
The preparation of rest seats must comply with specific sizes and shapes. Various technological systems such as Kavo PrepAssistant have been used an auxiliary method to evaluate preclinical preparations more objectively. aims this study were establish alternative system for evaluating occlusal compare different types assessment. Seventy‐six undergraduate students at Oporto University Faculty Dental Medicine in Portugal selected a convenience sample prepare two teeth #45 #46 (FDI World...
This study aimed to compare the cost and time implications for implant-supported prosthesis comparing three digital impression techniques: digitization with an intraoral scanner, of conventional (without dental casts) stone models.
Direct scanning of silicone impressions is a valid technique. However, studies in implant-supported rehabilitations are lacking. This vitro study aims to compare the trueness obtained with two types and their corresponding stone casts, using laboratory scanners full-arch implant rehabilitation. A master cast six dental implants was scanned 12-megapixel scanner obtain digital cast. Ten were made silicones (Zhermack Coltene) open-tray The casts by extraoral (Identica T500, Medit; S600 ARTI,...
Objectives: Considering the need for intraoral polishing of zirconia restorations, this in vitro study aimed to 1) evaluate 2D and 3D surface roughness different types ceramic after their finishing 2) compare three techniques using kits. Methods: Seventy-two specimens were obtained from two 3Y-TZP zirconia. After sintering, a layer glass-based fluorapatite veneering was applied over 24 one ceramics. Thus, surfaces set: Prettau Anterior, Zirconia, IPS e.max Ceram. The polished with universal...
This pilot study aimed to compare the fit accuracy of cobalt–chromium (Co-Cr) and polyether ether ketone (PEEK) removable partial denture frameworks, produced by digital technologies. Two models previously prepared Kennedy’s Class I III mandibular dental arches were scanned. For each model, two frameworks digitally designed manufactured using a Co-Cr alloy via selective laser melting (SLM) technique, PEEK milling technique. A qualitative assessment framework’s corresponding was carried out...
