The effect of build orientation on the microstructure and properties of selective laser melting Ti-6Al-4V for removable partial denture clasps
Abstract Statement of problem Selective laser melting (SLM) Ti-6Al-4V has been used for removable partial dentures, but the impact of SLM Ti-6Al-4V build orientation is not evident. Purpose The purpose…
Effect of scan pattern on complete-arch scans with 4 digital scanners
Abstract Statement of problem Complete-arch digital scans are becoming popular as digital dentistry is adopted for expanded clinical situations such as complete-arch prostheses, removable prostheses, extensive implant-supported treatment, and orthodontic…
Accuracy of different digital scanning techniques and scan bodies for complete-arch implant-supported prostheses
Abstract Statement of problem The effect of various scan bodies and scanning techniques on the accuracy and scan time for completely edentulous patients is not well understood. Purpose The purpose…
Rehabilitation of a patient after a total maxillectomy with a 2-piece magnetically retained obturator: A clinical report
Abstract After ablative surgery, especially a total maxillectomy, an obturator is commonly used as a method of reconstruction. However, the loss of a palatal denture-bearing area and vestibular retentive undercuts…
Activity of chitosan antifungal denture adhesive against common Candidaspecies and Candida albicansadherence on denture base acrylic resin
Abstract Statement of problem Candida adherence to the denture base is an important cause of denture stomatitis. In addition, infections with drug-resistant Candida have become more prevalent, especially among elderly…
Orthodontic elastomeric chain as an alternative to dental floss for splinting implant impression copings for complete-arch implant impressions
The most significant step in fabricating an accurate implant prosthesis is to transfer the precise 3D intraoral location of the implants to the definitive cast. Various impression techniques have been…
The effect of stainable drinks followed by simulated brushing on the roughness and stainability of acrylic resins polymerized with different cycles
Abstract Statement of problem No information is available on roughness and stainability of acrylic resins polymerized by experimental microwave cycles after immersion in stainable liquids and simulated brushing. Purpose The…
Accuracy of marginal fit and axial wall contour for lithium disilicate crowns fabricated using three digital workflows
Abstract Statement of problem Comparative assessment of the effectiveness of computer-aided design and computer-aided manufacturing (CAD-CAM) technologies used to fabricate complete-coverage restorations is needed. A quantitative assessment requires precise documentation of…
Comparative analysis of denture base adaptation performance between pour and other conventional fabrication techniques
Abstract Statement of problem Studies assessing the comparative denture base adaptation performance of the pour technique for various palatal vault depths are sparse. Purpose The purpose of this in vitro study…
Accuracy of 3-unit fixed dental prostheses fabricated on 3D-printed casts
Abstract Statement of problem Three-dimensional (3D)–printed casts are used successfully as diagnostic casts in orthodontics. However, whether 3D-printed casts are sufficiently accurate to be used as definitive casts for fixed…
Accuracy of complete-arch implant impression made with occlusal registration material
Abstract Statement of problem Which impression material, impression tray type, and implant impression technique combination produces the most accurate complete-arch impression is unclear. Purpose The purpose of this in vitro study…
Comparison of marginal and internal fit of 3-unit zirconia frameworks fabricated with CAD-CAM technology using direct and indirect digital scans
Abstract Statement of problem Accurate marginal and internal fit of dental restorations are essential for their long-term success. The fit of zirconia restorations prepared using digital scan systems has not…
Comparative reproducibility analysis of 6 intraoral scanners used on complex intracoronal preparations
Abstract Statement of problem Although studies have reported the trueness and precision of intraoral scanners (IOSs), studies addressing the accuracy of IOSs in reproducing inlay preparations are lacking. Purpose The…
CAD-CAM milled dentures: The Geneva protocols for digital dentures
Abstract This technical report describes 2 workflows for fabricating computer-aided design and computer-aided manufacturing (CAD-CAM) milled complete dentures (CDs). The first technique illustrates a manufacturer-independent workflow using conventional clinical steps…
Does airborne-particle abrasion before, rather than after, zirconia sintering lead to higher mechanical strength even under aging challenge?
Abstract Statement of problem Information concerning the effect of airborne-particle abrasion before zirconia sintering on its strength after aging is lacking. Purpose The purpose of this in vitro study was to…
