Comparison Of Anterior Denture Teeth Arrangements Made With The Tooth Mold Template And Definitive Computer-Aided Design & Computer-Aided Manufacturing Complete Removable Dental Prostheses, Jose Antonio Sierra Apr 2017

Comparison Of Anterior Denture Teeth Arrangements Made With The Tooth Mold Template And Definitive Computer-Aided Design & Computer-Aided Manufacturing Complete Removable Dental Prostheses, Jose Antonio Sierra

Master's Theses (2009 -)

Introduction: There is a dearth of information in the refereed literature regarding esthetics of CAD/CAM complete removable dental prostheses (CRDPs). The purpose of this study was to investigate and compare the anterior denture teeth arrangement made with the medium-size anterior tooth mold template to CAD/CAM complete removable dental prostheses fabricated with bonded denture teeth and milled teeth. Material and methods: Poly-vinyl siloxane impression were made of an edentulous maxillary model and selected for use as the patient template. The edentulous model was mounted on a semi-adjustable articulator. Definitive impressions and jaw relation records were made according to the manufacturer’s protocol. …


Retention Of Resin Composite Cam Crowns Following Different Bonding Protocols, Amir Hossein Nejat Jan 2017

Retention Of Resin Composite Cam Crowns Following Different Bonding Protocols, Amir Hossein Nejat

All ETDs from UAB

Objectives: Resin composite CAM materials offer more efficient milling, however, there is a high incidence of clinical debonding when this material is used for full-coverage crowns. The aim of the present study is to evaluate the effect of different surface treat-ments and primers on the crown retention of a new resin composite CAM material. Methods: 120 molars were prepared with a 24 degree taper, 1.5mm height, and axial walls in dentin. Surface area was measured by digital microscopy and preparations were scanned with an intraoral scanner. Crowns were milled from an experimental com-posite material with 4mm occlusal height. Teeth were …
