Bonding Crowns And Bridges With Resin Cement, Nathaniel C. Lawson, Sharukh Khajotia, Ana K. Bedran-Russo, Kevin Frazier, Jacob Park, Ariene A. Leme-Kraus, Olivia Urquhart

School of Dentistry Faculty Research and Publications

Background

Bonding crowns and bridges with resin cement can improve retention and reinforcement of the restoration. However, there is variation in the steps taken by different practitioners to achieve this goal.

Methods

The authors developed a survey on bonding dental crowns and bridges with resin cement and distributed it electronically to the American Dental Association Clinical Evaluators (ACE) Panel on May 22, 2020. The survey remained open for 2 weeks. Descriptive data analysis was conducted using SAS Version 9.4.

Results

A total of 326 panelists responded to the survey, and 86% of respondents who place crowns or bridges use resin …

Dental Light-Curing Units: An American Dental Association Clinical Evaluators Panel Survey, Kevin Frazier, Ana K. Bedran-Russo, Nathaniel C. Lawson, Jacob Park, Sharukh Khajotia, Olivia Urquhart

School of Dentistry Faculty Research and Publications

Background

The ability to polymerize light-activated dental materials with dental light-curing units (DLCUs) has revolutionized dentistry. However, proper DLCU use is essential for ensuring the effectiveness and performance of these materials.

Methods

The authors developed an electronic cross-sectional survey in the American Dental Association Qualtrics Research Core platform. The survey included questions about DLCU use, unit type and selection, training, maintenance, technique, and safety measures. The authors deployed the survey to 809 American Dental Association Clinical Evaluators (ACE) panelists on October 9, 2019, and sent reminder links to nonrespondents 1 week later. They conducted exploratory and descriptive analyses using SAS …

Three-Dimensional Bioprinting Materials With Potential Application In Preprosthetic Surgery, Mina D. Fahmy, Hossein E. Jazayeri, Mehdi Razavi, Radi Masri, Lobat Tayebi

School of Dentistry Faculty Research and Publications

Current methods in handling maxillofacial defects are not robust and are highly dependent on the surgeon’s skills and the inherent potential in the patients’ bodies for regenerating lost tissues. Employing custom-designed 3D printed scaffolds that securely and effectively reconstruct the defects by using tissue engineering and regenerative medicine techniques can revolutionize preprosthetic surgeries. Various polymers, ceramics, natural and synthetic bioplastics, proteins, biomolecules, living cells, and growth factors as well as their hybrid structures can be used in 3D printing of scaffolds, which are still under development by scientists. These scaffolds not only are beneficial due to their patient-specific design, but …

Titanium Nitride And Nitrogen Ion Implanted Coated Dental Materials, Youssef S. Al Jabbari, Jennifer Fehrman, Ashley C. Barnes, Angela M. Zapf, David W. Berzins, Spiros Zinelis

School of Dentistry Faculty Research and Publications

Titanium nitride and/or nitrogen ion implanted coated dental materials have been investigated since the mid-1980s and considered in various applications in dentistry such as implants, abutments, orthodontic wires, endodontic files, periodontal/oral hygiene instruments, and casting alloys for fixed restorations. Multiple methodologies have been employed to create the coatings, but detailed structural analysis of the coatings is generally lacking in the dental literature. Depending on application, the purpose of the coating is to provide increased surface hardness, abrasion/wear resistance, esthetics, and corrosion resistance, lower friction, as well as greater beneficial interaction with adjacent biological and material substrates. While many studies have …
