Evaluation of Surface Roughness of Multilayered Monolithic Zirconia Following Chairside Adjustment with 3 Different Polishing Systems Sterilized for Multiple Cycles: An In Vitro Study.

BACKGROUND Chairside grinding, finishing, and polishing are essential for smoothing multilayered monolithic zirconia (MMLZ) restorations. Due to rubber matrix hardening, repeated sterilization of finishing and polishing instruments reduces their abrasive effectiveness. This study aimed to evaluate the effects of sterilization cycles on the effectiveness of 3 commercial polishing kits on the surface roughness of MMLZ crown restorations.

Linear Dimensional Accuracy in Maxillomandibular Records: A Comparative Study of Scannable and Transparent Materials.

BACKGROUND Maxillomandibular relationship records facilitate patient stomatognathic information transfer to dental laboratories, but new bite registration materials (BRMs) lack scientific evidence on linear dimensional accuracy. This in vitro investigation compared linear dimensional accuracy of 6 commercial scannable and transparent BRMs with a typical BRM at 1 h. MATERIAL AND METHODS Seven American Dental Association (ADA)-approved BRMs were categorized into 1 control and 2 experimental groups: control: Occlufast Rock; scannable group: Occlufast CAD, Virtual CADBite, and Flexitime Bite; and transparent group: Maxill Bite, Charmflex Bite, and Defend ClearBite.

Dimensional Accuracy of Intraoral Scanners in Recording Digital Impressions of Post and Core Preparations: A Systematic Review.

Background: This study aims to perform a review by selecting, analyzing, and evaluating articles that discuss the accuracy of intraoral scanners (IOSs) in recording post space compared to conventional impression-making techniques.

Methods: The review question framed using the PITR framework (participant, index test, targeted condition, and reference standard) is as follows: What is the dimensional accuracy (T) of impressions made using intraoral scanners (I) for post space (P) compared to impressions made using conventional techniques and digitalized using extraoral scanners (R)? Four electronic databases were searched using pre-set keywords. The guidelines and strategies recommended by PRISMA formed the basis for planning, executing, and documenting this systematic review.

Accuracy of 3 Intraoral Scanners in Recording Impressions for Full Arch Dental Implant-Supported Prosthesis: An In Vitro Study.

BACKGROUND This study used an edentulous mandibular resin model with 6 parallel osteotomy sites and aimed to compare the accuracy (trueness and precision) of 10 digital impressions using 3 intraoral scanners, the 3Shape TRIOS 5, Medit i700, and Primescan, using Medit Link v3.3.2 software.

Navigating Esthetic Challenges: Immediate Implant Placement and Comprehensive Restorative Solutions-A Clinical Case With 2-Year Follow-Up Study.

The esthetics of immediate implant dentistry can be challenging. Clinical considerations for immediate implant placement have demonstrated long-term success rates comparable to traditional delayed implant protocols. However, it is a sensitive technique that requires proper treatment planning as well as meticulous execution to be predictable and successful in the long term.
