A method for digital fabrication of an implant-supported soft tissue graft stent to protect, shape, and ensure intimate adaptation of the complete arch graft to the periosteum surrounding dental implants is described. To fabricate the stent, an extraoral scanner was used to convert the implant cast into digital data. Dental design software was then used to fabricate the stent, which is produced by 3-dimensional (3D) printing.

This clinical report describes the use of a chairside intraoral scanner for a patient with a hypersensitive gag reflex. The technique proved to be a more comfortable alternative for the patient and an accurate method for the clinician to capture both hard and soft tissue detail for the fabrication of a definitive obturator.

A technique is presented for designing and fabricating a computed tomography-based surgical guide to place definitive implants before orthodontic therapy. First, the diagnostic cast and the orthodontic tooth arrangement and diagnostic waxing cast are scanned with a 3-dimensional optical scanner.

The patient, an upper limb amputee, had subjected the original IRFCDP to parafunctional forces generated from use as a replacement hand in a compensatory technique commonly taught in rehabilitation. Advantages of the technique are that it provides an alternative to remaking the entire prosthesis, which was otherwise satisfactory; it adapts to a variety of situations involving anterior tooth reinforcement; and it offers a potential solution to anterior prosthetic tooth damage caused by other types of parafunction.

Purpose: The purpose of this study was to determine if there are specific measurements made on an edentulous cast that could be useful to clinicians for selection of proper maxillary anterior denture tooth width.
Material And Methods: Following Institutional Review Board approval, measurements were made on 50 maxillary and mandibular sets of complete denture casts and their marked and contoured occlusion rims and record bases consecutively submitted to a dental laboratory.
This article describes a method of in-office fabrication of an occlusal device for treatment of bruxism patients seeking a less costly alternative to laboratory-processed splints. This technique eliminates the need for mounted casts and the expense and delay associated with commercial laboratory involvement. It also minimizes patient and operator exposure to acrylic resin monomer and high temperatures associated with its polymerization reaction by use of a light-polymerized blue urethane dimethacrylate resin.

However, these compounds have been shown to be tissue irritants and capable of producing allergic reactions. An anonymous, self-administered questionnaire was distributed to 56 second-year dental students who had used an irreversible hydrocolloid containing a quaternary ammonium compound as an antimicrobial (Jeltrate Plus) to make impressions during a summer preclinical occlusion course.

Purpose: The purpose of this study was to determine the philosophies of dental educators throughout the United States at both the predoctoral and postdoctoral levels and to compare their attitudes toward desirable maxillomandibular relationships in defined clinical situations.
Material And Methods: A survey was constructed with 5 clinical scenarios presented describing patients with a difference between maximum intercuspation and centric occlusion.
