Official title

Removable Partial Denture Abutments Restored With Monolithic Zirconia Crowns: A Randomized Controlled Trial

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this study is to investigate the use of an all-ceramic dental crown material to restore the abutment teeth of partially-edentulous patients who need removable partial dentures (RPD). The outcomes of the treatment group (all-ceramic crowns) will be compared to a similarly-treated control group whose RPD abutment teeth are restored using conventional metal and metal-ceramic crowns. Primary outcomes of interest include crown survival, abutment tooth survival and RPD survival.The null hypothesis is that at the conclusion of the study there will be no differences in outcomes between the two groups. All dental treatment, including dental hygiene and periodontal care, fillings, crowns and RPD fabrication will be provided by predoctoral dental students in the University of Kentucky College of Dentistry student clinics. Students treating the subjects will be supervised by licensed, technique-calibrated faculty specialists. Following the completion of dental treatment, enrolled subjects will be clinically re-evaluated by investigators at 6 months, and at annual intervals thereafter for 5 years following RPD delivery.
