An investigation into aspects of resin retained bridge design on aesthetics and oral health related outcomes

Objective: To assess whether removing the incisal metal edge of an anterior resin-retained bridge (RRB) improves aesthetics without compromising clinical performance. Design: A two-phase study was conducted. Phase 1 involved a randomised, controlled trial of 40 dental patients requiring anterior tooth replacement, who received either the original or an adjusted RRB design. Participants completed an oral health-related quality of life (OHRQoL) questionnaire before and after treatment. Phase 2 assessed aesthetic preferences among three groups—hypodontia patients, the public, and dental care professionals—who rated photographs of both RRB designs using a 5-point Likert scale. Results: In Phase 1, both groups showed p
