Educational researchers have argued for the addition of new technologies to enhance or replace traditional dental education modalities to more effectively engage and appeal to the new generation of dental students. Two-and three-dimensional interactive media technology is now available for implementation into curricula to teach to a next-generation paradigm. The purpose of this study was to analyze the introduction of a unique, online, totally independent learning module for dental morphology instruction, completely replacing the traditional classroom teaching of the topic, and to determine the relationship between its use and parameters depicting success in learning dental morphology. In particular, the authors hypothesized that the novice, preclinical dental student can learn dental morphology independently and eficiently this way. One-third of a 2010-11 irst-year class of dental students were given an independent, interactive media module for the instruction of dental morphology. The remaining members of the class experienced the traditional course with classroom lectures. At the end of the module, a written examination and survey were given to both groups. The major indings were that the independent, interactive media module was just as effective as the traditional classroom method for successful dissemination of foundational knowledge in dental morphology; the independent study group performed signiicantly better on the didactic examination; the online module positively engaged the students; and students preferred the interactive media module but did not regard it as a total replacement for the traditional course.Dr. Maggio is Assistant Professor and Academic Clinician,
Objective: Bi-layer zirconia-based posterior fixed dental prostheses (FDPs) have reportedly a high incidence of veneering ceramic fractures. The CADon technique employs zirconia frameworks veneered with milled lithium disilicate glass-ceramic to overcome these shortcomings but long-term clinical studies are missing. This study evaluated the clinical efficacy of posterior 3-unit CADOn FDPs over a 5-year period.Materials and Methods: A total of 25 patients, 16 male and 9 female with a mean age of 55.6 years, received a total of 25 posterior three-unit CADOn FDPs. Patients were recalled for baseline and for follow-up visits at 6, 12, 24, and 60 months.Parameters evaluated were fracture, marginal adaptation, marginal discoloration, wear, polish, color match, surface staining, and retention of these restorations as well as secondary caries of the abutment teeth.Results: A total of 21 FDPs evaluated at 60-months revealed a 100% survival rate.All evaluated clinical parameters were satisfactory (alpha or bravo) and there was no statistically significant difference at different time points, except for surface staining, which was also worse at 60 months compared to baseline (p ≤ 0.001). Conclusions: CADOn three-unit posterior FDPs demonstrate excellent fracture resistance after 5 years of clinical function. All evaluated clinical parameters were satisfactory, except for surface stain, which also increased over time. Clinical Significance: Conventionally veneered bi-layer zirconia-based posterior FDPs have limited clinical success. Based on this study, alternative methods such as zirconia frameworks veneered with milled lithium disilicate glass-ceramic provide a viable alternative with excellent long-term clinical outcomes.
