This article describes a technique to implement guided tooth preparation where the tooth is virtually prepared in the laboratory and preparation templates are created for chairside use....
Prior to any tooth preparation, patient records are acquired with an intra-oral scanner, both stump and final shades are selected, and digital photos are taken. These digital records are used in combi...
The traditional approach of tooth preparation has evolved from historically preparing a tooth without any pretreatment guidance to, more currently, preparing the tooth through a mock-up of the desired...
This is a unique approach in digital restorative dentistry....
This study aimed to investigate the accuracy of automatic tooth finish line registration compared to manual registration with regard to various finish line configurations and dental computer-aided des...
Finish line registrations were performed on 15 digital tooth models with different finish line configurations (edge roundness radius = 0 mm, 0.2 mm, and 0.4 mm; edge angle = 30°, 60°, 90°, 120°, and 1...
The finish line configurations, registration methods, and CAD software interacted with the accuracy of the registered finish line (p = 0.001). The automatic finish line registration method exhibited l...
Finish line registration errors may occur when the automatic registration method is applied to the indistinct edge of tooth preparation. The accuracy of the automatic finish line registration could di...
Gaze behavior can serve as an objective tool in undergraduate pre-clinical dental education, helping to identify key areas of interest and common pitfalls in the routine evaluation of tooth preparatio...
Thirty-five participants volunteered to participate in the study and were divided into a novice group (dental students, n = 18) and an expert group (dental educators, n = 17). Each participant wore a ...
Based on the participants' mean rates, the "best" and the "worst" tooth preparations were selected for analysis. The results showed a significantly longer time to decision in the novices compared to t...
The current study showed distinct differences in gaze behavior between the novices and the experts during the evaluation of single crown tooth preparation. Understanding differences in gaze behavior b...
The purpose of this study was to evaluate the use of magnifying loupes (×2.5) on the quality of tooth preparation for complete coverage crowns; performed by predoctoral students using an objective and...
Forty-two predoctoral students were randomly assigned into 2 groups to perform tooth preparation for a complete coverage crown on a mandibular first molar in a manikin, with and without the use of mag...
No significant differences in the measured outcomes were found between the groups with or without the use of magnifying loupes (p > .002). The majority (>50%) of both groups had no undercuts (99.3% an...
Within the limitations of this study, the use of magnification loupes does not appear to significantly improve the quality of tooth preparation for complete coverage crown. The TOC was also found to b...
To measure the effect of different tooth preparation finishing procedures (super-coarse grit, fine grit, and air-particle abrasion) and immediate dentin sealing (IDS) on the scanning accuracy of 4 int...
A tooth preparation for a full-coverage restoration was performed on an extracted mandibular molar using super-coarse diamond burs. Four groups were created depending on the tooth preparation finishin...
Tooth preparation finishing procedures (P<.001) and the IOS assessed (P<.001) were significant predictors of the trueness and precision values obtained. The highest trueness and precision values were ...
The different tooth preparations finishing procedures tested influenced on the scanning accuracy of the 4 IOSs considered. The air-particle abrasion procedure obtained the best accuracy values. The tr...
The tooth preparation finishing procedure used can reduce the intraoral scanning accuracy of any of the intraoral scanners tested. The air-particle abrasion finishing procedure might be recommended fo...
In clinical settings, tooth preparation for prefabricated zirconia crowns (PZCs) in the primary dentition varies widely. However, knowledge about the biomechanical behavior of PZCs in various clinical...
3-dimensional models of the PZC, cement, and tooth with six different conditions were simulated in primary molar teeth, incorporating cement thickness (100, 500, and 1000 μm) and cement type (resin-mo...
The overall stress of tooth was increased as the cement space increases under oblique loading. The von Mises stress values of the resin cements were significantly higher than those of the resin-modifi...
Within the limits of this study, cement type has a greater influence on the biomechanical behavior of PZCs than cement thickness....
In the light of the digital teaching, it is necessary that the effectiveness of a new digital real-time evaluation system in the preclinical training of tooth preparation be evaluated....
Forty undergraduate dental students of the fourth year were randomly divided into the control group and the experimental group to complete the training task of tooth preparation for porcelain fused to...
There was no significant difference between the scores of the experimental group and the control group (p > .05). The students of two groups obtained the similar scores in the test (p > .05). Most of ...
The digital real-time evaluation system could provide effective training effects for the dental undergraduate students in the preclinical training of tooth preparation in fixed prosthodontics....
This article describes a completely digital workflow for ceramic veneer preparation with computer-aided design and computer-aided manufacturing technology. A simplified 3-dimensionally printed tooth r...
This systematic review is aimed to evaluate in fixed prosthodontics treated teeth, the effect of the BOPT on periodontal health compared to the horizontal preparation technique using a chamfer finishi...
The electronic databases Cochrane Central Library, PubMed, Scopus, and ScienceDirect were searched based on specific MeSH keywords. The Randomized controlled clinical trials (RCTs) and prospective cli...
Eight studies were included in the systematic review and only three RCTs were involved in the...
Considering the limitation of this review, the BOPT is comparable to chamfer preparation and it resulted in an acceptable effect to maintain periodontal health with a high success rate. However, more ...
With the increasing interest in using robots in dentistry and the widespread dissemination of information on this topic and its applications, a comprehensive review of robot applications in prosthodon...
The purpose of this scoping review was to assess the current status of prosthodontic robotic applications, their achievements to date, and the barriers hindering their broader adoption and further adv...
The checklist for Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) was used to conduct this review. A comprehensive search methodology was ...
Eighteen relevant studies were found. Of these, 10 studies focused on assessing the effectiveness of robotic systems through in vitro testing using phantom models for tooth preparation. These studies ...
Robots have the potential to improve precision and accuracy in prosthetic dentistry. However, clinical studies are needed to confirm the widespread use of robots in prosthodontics, as their clinical a...
