A Comparison Of Orthodontic Intraoral Scan Results Between Staff And Volunteers, Andrew Lee

UNLV Theses, Dissertations, Professional Papers, and Capstones

Objective: This pilot study is the first to assess and compare a trained staff’s intraoral scan to a clinical examination by comparing the overbite, overjet, Angle canine and molar classification, and gingival health. The second part of this study is to determine if the self-scan scan from a patient is as reliable to the staff’s scan. Introduction: Orthodontic treatment is usually provided over a sequence of appointments. During each appointment, the doctor clinically evaluates the patient, analyzes the progress and provides adjustments to continue with the treatment. The most common clinical criteria evaluated are overbite, overjet, upper and lower midlines, …

Erupted Compound Odontoma Associated With Missing Tooth: A Rare Case Report, Weeraya Tantanapornkul, Ruchadaporn Kaomongkolgit, Sirilawan Tohnak, Lalitkorn Promma, Soranan Chantarangsu

Journal of Dentistry Indonesia

Odontomas are one of the most frequently found odontogenic tumors that consist of dental tissues. Odontomas have been classified into two types: compound and complex odontomas. They are usually discovered on routine radiographic examination. In rare cases, the odontoma erupt into the oral cavity, called an erupted odontoma. The first case was published in 1980, and since then, there have been not more than 50 cases being reported in the literature. Most of the reported cases are erupted complex odontoma. This case report represents a rare case of an erupted compound odontoma in a young patient who came with the …

A Comparison Of Three-Dimensional Printing Technologies On The Precision, Trueness, And Accuracy Of Printed Retainers, Owais A. Naeem

Theses and Dissertations

Purpose: The aim of this study was to evaluate the differences in the precision, trueness, and accuracy of 3D printed orthodontic clear retainers produced using printer systems with various printing technologies.

Methods: Retainers (n=15) were printed using four different 3D printers: a stereolithography (SLA) printer, two different digital light processing (DLP and cDLP) printers, and a polyjet photopolymer (PPP) printer. The 3D printed retainers were transformed into a digital file through a cone-beam computed tomography scan that was compared to the original image using a 3D superimposition analysis software. At previously chosen landmarks (R6, L6, R3, L3, R1, L1) retainers …

The Effect Of Print Angulation On The Accuracy And Precision Of 3d-Printed Orthodontic Retainers, Allison Williams

Theses and Dissertations

Purpose: The aims of this study were: 1) to compare the accuracy and precision of 3-

dimensional (3D) printed retainers at various angulations, 2) to evaluate the effect of angulation

on printing time and the amount of resin consumed.

Methods: Using a stereolithography (SLA) 3D printer, a total of 60 clear retainers were printed at five angulations (n=12, each): 15, 30, 45, 60, and 90 degrees. Six retainers were printed each cycle at a random order for all print angulations as print 1 and print 2. Digital images of the original and printed retainers were superimposed. Discrepancies on eight landmarks …

Calibration Of Periodontal Diagnosis Among Participants Of Various Dental Education Levels, Shadi Alkhoury

All ETDs from UAB

ABSTRACT: The purpose of this project is to assess the level of calibration among dental students of two different education levels and postgraduate students of two different dental specialties during diagnosis and treatment planning of clinical cases with various levels of periodontal involvement, using the 2018 Classification of Periodontal and Peri-implant Diseases and Conditions. Fifty-seven second year dental students (D2), 45 fourth year dental students (D4), 17 orthodontic postgraduate students (OS) and 12 postgraduate periodontology (PS) students were presented with an anonymous survey of 10 different cases, each with 5 choices of diagnosis and 7 therapeutic approaches. Consensus diagnosis was …
