Masticatory Efficiency, Bite Force, and Patient-Reported Outcomes in Patients Rehabilitated With Complete and Partial Dentures Supported by Teeth, Mini-Implants, or Conventional Implants

This study aims to evaluate masticatory efficiency, bite force, and patient-reported outcomes in edentulous and partially edentulous patients rehabilitated with different removable prosthodontic treatment modalities. The study includes both cross-sectional and longitudinal components. The cross-sectional component will compare patients wearing conventional complete dentures, conventional removable partial dentures, mini-implant-retained overdentures, conventional implant-retained overdentures, and implant-assisted removable partial dentures. The longitudinal component will assess changes in masticatory performance, bite force, and patient-reported outcomes following prosthodontic rehabilitation and adaptation over time. The study seeks to determine whether implant-assisted treatment options provide superior functional outcomes, oral health-related quality of life, and patient satisfaction compared with conventional removable prostheses.

A Prospective Clinical Trial Evaluating Outcomes of Surveyed Zirconia Crowns

Zirconia has shown to be a suitable substitute for metal ceramic crowns when comparing survival, biological and technical complications. Evidence demonstrating the outcomes of surveyed zirconia crowns on removable partial denture abutments is unavailable. Zirconia as a substitute for metal ceramic is being currently used for fabricating surveyed crowns although quantitative data evaluating its efficacy is sparse. The purpose of this prospective clinical trial is to evaluate clinical outcomes when zirconia is used as a full coverage restoration on removable partial denture abutments. The study will be designed as a 3-5 year prospective observational trial in the University of Toronto undergraduate clinic in a controlled environment. Outcomes measures will include survival, biological and technical complications. Descriptive statistics will be used to summarize patient characteristics and outcomes and for categorical variables frequency and percentages will be reported. A level of significance 0.05 will be used for inferential analysis, with p-values \< 0.05 reported as statistically significant. It is expected that zirconia will demonstrate similar outcomes to traditional metal ceramic surveyed crowns.
