The Quantification Of Tooth Displacement, Thomas W. Radmer, L Thomas Johnson, Mingan Yang, Thomas Wirtz

School of Dentistry Faculty Research and Publications

By using reference points from a single pixel marker placed at the center point of the cuspid teeth and the center point on each of the incisor teeth, a polynomial curve was generated as a native curve for each dental arch studied. The polynomial curve generated from actual tooth position in each arch provides the forensic odontologist with another reference point that is quantifiable. The study represents that individual characteristics, such as tooth displacement, can be quantified in a simple, reliable, and repeatable format.

Maximizing Beneficence And Autonomy: Ethical Support For The Use Of Non-Pharmacological Methods For Managing Dental Anxiety, Evelyn Donate-Bartfield, Ryan Spellecy, Nicolas J. Shane

School of Dentistry Faculty Research and Publications

This article examines advantages associated with nonpharmacological behavioral management techniques and suggests that there are benefits to their use (such as achieving a more lasting solution to the problem of dental anxiety) that are not realized with medication-based interventions. Analyses that use Kantian and existential viewpoints for exploring the use of medication versus behavioral interventions for managing life problems yield parallel conclusions: there are advantages gained by using behavioral interventions that are not always associated with medication-based interventions. These analyses, taken together with an understanding of the psychology of dental anxiety management, suggest that using nonpharmacological techniques for the management …

The Incidence Of Maxillary Sinus Retention Cysts In Orthodontic Patients, Jose A. Bosio

School of Dentistry Faculty Research and Publications

Maxillary sinus retention cysts are occasionally found on dental radiographs. The objective of this study was to verify the frequency of maxillary sinus retention cysts in consecutive panoramic radiographs from 173 patients (77 males, 96 females) in an orthodontic office. The chi-square test was used for statistical analysis. Ten patients (5.8%) of the total sample presented a maxillary sinus retention cyst. Males had a higher frequency (9.1%) than females (3.1%), but this difference was not significant (P > .05). Overall, the frequency of maxillary sinus retention cysts in orthodontic patients is rather low and does not differ from the general population.

The Correlation Of Dental Arch Width And Ethnicity, Thomas W. Radmer, L Thomas Johnson

School of Dentistry Faculty Research and Publications

This study sought to demonstrate a correlation between arch width, ethnic background, individual height, weight, and whether orthodontic treatment had been rendered. Conclusions revealed that arch widths were significantly larger (p= 0.002 for the mandible and p= 0.008 for the maxilla) in non-Whites than in Whites. In addition, arch widths of the mandible were significantly larger in individuals who had had orthodontic treatment compared to those who had not (p=0.005). This did not carry through to those arch widths in the maxilla of orthodontic versus nonorthodontic care (p=0.258).

Repairing An Implant Titanium Milled Framework Using Laser Welding Technology: A Clinical Report, Soni Prasad, Edward A. Monaco, Jr.

School of Dentistry Faculty Research and Publications

The application of laser welding technology allows titanium to be welded predictably and precisely to achieve accurate fit of a milled framework. Laser energy results in localized heat production, thereby reducing thermal expansion. Unlike soldering, laser energy can be directed to a small area, making it possible to laser weld close to acrylic resin or ceramic. This article describes the use of laser welding to repair an implant titanium milled fixed denture. A quick, cost-effective, accurate repair was accomplished, and the repaired framework possessed adequate strength and the same precise fit as the original framework.

Altering Occlusal Vertical Dimension Provisionally With Base Metal Onlays: A Clinical Report, Soni Prasad, Jennifer Kuracina, Edward A. Monaco, Jr.

School of Dentistry Faculty Research and Publications

This article presents a method for altering occlusal vertical dimension (OVD) to restore dentitions with limited restorative space due to loss of tooth structure. A provisional increase in OVD is achieved using predominately base metal onlays, which offer advantages over conventional techniques. The onlays are resistant to wear, may be bonded well to nonrestored and restored tooth surfaces with resin cements, and provide a fairly reversible method of increasing OVD. A patient situation is presented which demonstrates the use of provisional base metal onlays in complete mouth rehabilitation.

School of Dentistry Faculty Research and Publications

Intrusive luxation of primary teeth carries a high risk of damage to underlying permanent tooth germs. Ectopic eruption of permanent incisors is an unusual outcome of traumatic injury to their predecessors. In this case report, we describe the multidisciplinary management of the consequences of a primary tooth intrusion that led to severe ectopic eruption of the permanent left central incisor in a horizontal position at the level of the labial sulcus.

A Technique For Duplicating A Fixed Complete Denture, Soni Prasad, Edward A. Monaco, Jr.

School of Dentistry Faculty Research and Publications

The fixed implant prosthesis often requires repair due to fracture and/or wear of acrylic resin teeth. Repair of such a prosthesis, although simple, requires retaining the prosthesis to be revised in the laboratory. In order to reveneer the implant prosthesis, a provisional restoration should be fabricated for the patient that provides similar function and esthetics. This article presents a technique for duplicating the existing fixed implant-supported prosthesis prior to repair/reveneer, thus providing a smooth transition from the provisional to the definitive prosthesis.
