Preliminary application and evaluation of digital step-by-step tooth-preparation templates.

The Journal of prosthetic dentistry (Print), 2021
STATEMENT OF PROBLEM Tooth preparation is a fundamental technique, and inaccurate preparation may lead to excessive irreversible tooth removal or insufficient restorative space. The conventional process depends mostly on operator experience, and variable

Controlled tooth preparation

The Journal of Prosthetic Dentistry, 1971
lh e purpose of this report is to describe a new system of tooth preparation, by “controlled tooth reduction.” This means that all the reductions of tooth structure in an axial plane are made with the high-speed handpiece locked in a paralleling device. This applies to both intracoronal and extracoronal reduction.

Evaluating the Feasibility of Using Augmented Reality for Tooth Preparation

2024 IEEE Conference on Virtual Reality and 3D User Interfaces Abstracts and Workshops (VRW)
Tooth preparation is a fundamental treatment technique to restore oral function in prosthodontic dentistry. This technique is complicated as it requires the preparation of an abutment while simultaneously predicting the ideal shape.

Resistance form in tooth preparation

Dental Clinics of North America, 2004
Theoretical and clinical studies of resistance form are reviewed, supporting the basic prosthodontic principle that resistance form is an essential element in preparation design. Concepts of the"on-off" nature of resistance form, its application in guidelines for minimally acceptable preparation taper, and the controversy over whether there is a ...

TOOTH PREPARATION AND PULP DEGENERATION

The Journal of the American Dental Association, 1997
Conscious attention must be directed toward providing atraumatic tooth preparations for crowns, and to constructing adequate provisional restorations. If meticulous care is not taken, pulpal damage or death can occur. Patients should be warned that pulpal death and endodontic therapy can result from crown placement.

Minimal tooth preparation for posterior monolithic ceramic crowns: Effect on the mechanical behavior, reliability and translucency.

Dental Materials, 2020
OBJECTIVE Despite the increased use of monolithic crowns, their performance has yet to be determined when the minimal tooth preparation (MTP) principle is considered.

Effect of tooth preparation design on marginal adaptation of composite resin CAD-CAM onlays.

The Journal of prosthetic dentistry (Print), 2020
STATEMENT OF PROBLEM Although different preparation designs have been proposed for onlays fabricated by computer-aided design and computer-aided manufacturing (CAD-CAM), their effect on marginal adaptation is unclear.

Influence of Tooth Preparation Design and Scan Angulations on the Accuracy of Two Intraoral Digital Scanners: An In Vitro Study Based on 3-Dimensional Comparisons.

Journal of Prosthodontics, 2020
PURPOSE To evaluate the accuracy of two intraoral scanners (IOS) in terms of different preparation designs and scan angulation limitation due to the presence of adjacent teeth.
