From Silos To Systems: A Conceptual Framework For Workforce Aligned Oral Health Education, Meghan Bastin Jan 2026

From Silos To Systems: A Conceptual Framework For Workforce Aligned Oral Health Education, Meghan Bastin

2026 Scholarly Teaching Conference: Poster Session Papers

In the current U.S. educational system, becoming a dentist follows a few prescriptive pathways.  Learners typically complete an undergraduate degree before entering time-intensive doctoral training.  This results in only 3-4 years of direct professional education embedded within an eight -year process, while learners accumulate significant financial investment in their education.  With the average cost of graduate-level dental education alone exceeding $300,000 and new federal borrowing limits likely to further constrain access, there is an opportunity to explore alternative ways of structuring oral health education.

This poster presents a conceptual, system-level framework that explores a perspective in which oral health education …


Implant Overdenture Abutment Loosening Under Hyperbaric Conditions, Zana Jamal Al-Saloum Jan 2024

Implant Overdenture Abutment Loosening Under Hyperbaric Conditions, Zana Jamal Al-Saloum

Graduate Theses, Dissertations, and Problem Reports (ETD)

Objectives: To investigate the effect of various hyperbaric air pressures on the loosening of LOCATOR® (ZEST Anchors, LLC, Escondido, CA USA) overdenture abutments.

The pressure conditions tested are meant to simulate scuba diving conditions in edentulous patients that are restored with implant-retained tissue-supported overdentures. Another sub-goal of this study is to determine whether or not there is a difference in LOCATOR® loosening when the sample is exposed to six cycles/dives as opposed to one cycle/dive.

Methods: 36 ZimVie Tapered Screw Vent Implants with a 3.5mm diameter implant platform, and a 2.5mm diameter (and 1.5mm deep) internal hexagon were …


Accuracy Of Digital Impressions At Varying Implant Depths: An In-Vitro Study, Vivia Sequeira Jan 2021

Accuracy Of Digital Impressions At Varying Implant Depths: An In-Vitro Study, Vivia Sequeira

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction: Implants placed at variable depths may vary the amount of visible scannable surface of a scan body. Intraoral scanner technology uses advanced optical principles to record the surface of the scan body to accurately capture the implant position.

Purpose: To investigate the effect implant placement depth has on the accuracy of digital implant impressions using an intraoral scanner.

Materials & Methods: A partially edentulous gypsum master model was fabricated to allow the positioning of a single implant analog at different depths. Four groups based on the planned implant depths of 0, 3, 6 and 7mm and corresponding visibility of …


The Visual And Spectrophotometric Effect Of External Bleaching On Omnichroma Resin Composite And Natural Teeth, Michael Brian Evans Jan 2020

The Visual And Spectrophotometric Effect Of External Bleaching On Omnichroma Resin Composite And Natural Teeth, Michael Brian Evans

Graduate Theses, Dissertations, and Problem Reports (ETD)

Objective: To determine the visual and spectrophotometric effect external tooth bleaching has on natural tooth structure and OMNiCHROMA composite at various number of treatments. Variables were compared to determine if there is a detectable difference between the composite and the tooth before and after bleaching.

Methods: Preparation and restoration of 25 previously extracted teeth was completed. OMNiCHROMA composite was used. Each tooth was measured visually with a VITA shade guide and a colorimeter. Measurements were recorded before bleaching, after 5 and 10 treatments. Statistical analysis was completed and ΔE values between the composite and tooth were compared between the 3 …


Effect Of Shear Bond Strength With Novel Apc™ Flash-Free Brackets And Different Bonding Protocol: An In Vitro Study, Carl Bernstein Jan 2019

Effect Of Shear Bond Strength With Novel Apc™ Flash-Free Brackets And Different Bonding Protocol: An In Vitro Study, Carl Bernstein

Graduate Theses, Dissertations, and Problem Reports (ETD)

Background and Objectives: In today’s time, there is an increasingly crowded field of competition vying over a small subset of the population. Now, more than ever it is imperative to compete with efficiency and esthetics. Each step for orthodontic bonding procedures increases the chance for error to occur. However, orthodontic bracket, etchant, sealant, and adhesive material has the ability to improve bond strength and final outcome for the patient and provider. The aim of this study was to determine effective bonding protocols for Advanced Clarity APC™ Flash-Free Brackets and to determine if adhesive remains on enamel or orthodontic bracket after …
