Effect of Metal Artifacts in Cone-beam Computed Tomography on Accuracy of Implant Placement by Static and Dynamic Computer- Assisted Implant Surgery: An In Vitro Study.

Purpose: This study evaluates the impact of metal artifacts in cone-beam computed tomography (CBCT) on the accuracy of static and dynamic computer-assisted implant surgery (CAIS) techniques.

Materials And Methods: An implant was placed on each of thirty 3D-printed models embedded with Cobalt-Chrome strips to simulate metal artifacts by Porcelain-fused-to-metal (PFM), utilizing these CAIS techniques: radiographic template (RT) (n=10), radiographic markers (RM) (n=10), and dynamic navigation (DN) (n=10). Trueness and precision were analyzed by comparing 3D global deviation and the difference in implant positions at the neck, apex, depth, and angle in initial planned and final placed scans.

Computer-Assisted Porcelain Laminate Veneer Preparation: A Scoping Review of Stereolithographic Template Design and Fabrication Workflows.

Computer-assisted preparation of porcelain laminate veneers (PLVs) using stereolithographic templates has been developed to enhance the accuracy of tooth preparation. However, the digital workflows involved in guided PLV preparation remain inconsistently defined across various practices. Therefore, this scoping review aimed to examine publications on computer-assisted PLV preparation to identify the key stage of digital workflows involved in designing and fabricating stereolithographic templates, as well as to highlight the limitations of various template designs.

Accuracy of Complete-Arch Scans Obtained by Intraoral Scanner and Smartphone Three-Dimensional Scanning Applications With Different Smartphone Position Setups: An In Vitro Study.

Introduction: The high cost of intraoral scanners (IOS) for complete-arch scans makes them less accessible for many dental practitioners. As a viable alternative, smartphone scanner applications (SMP) provide comparable scanning capabilities at a significantly low cost. However, there is limited data on the accuracy of SMP, especially when used in various smartphone positions.

Digitally versus conventionally fabricated complete dentures: A systematic review on cost-efficiency analysis and patient-reported outcome measures (PROMs).

Statement Of Problem: Reports on digitally fabricated complete dentures are increasing. However, comprehensive evidence-based research on their cost-efficiency and patient-reported outcome measures (PROMs) is lacking.

Purpose: The purpose of this systematic review was to compare the cost-effectiveness and PROMs between digitally and conventionally fabricated complete dentures.

Development and validation of a questionnaire on perceived prosthodontic treatment needs in Malaysian adults.

Statement Of Problem: A discrepancy between dentists' assessments and patients' expectations during prosthodontic treatment is inevitable. Incorporating dental patients' concerns about their prosthodontic treatment needs is essential during treatment planning, yet studies assessing these needs in adult dental patients are lacking.

Purpose: The purpose of this study was to develop and validate a novel instrument, termed the questionnaire on perceived prosthodontic treatment needs (PPTN), that assesses perceived prosthodontic treatment needs in adults.
