About

Removable partial dentures (RPDs) are traditionally fabricated by lost-wax casting technique, a time-consuming and very laborious manual technique. Recently, fabricating removable partial dentures using computer designing and laser sintering techniques have been introduced. The purpose of this study was to evaluate the patient satisfaction with new computer-generated removable partial dentures and compare it to the traditional removable partial dentures.

Full description

Patients seeking Removable partial dentures in the undergraduate clinic at McGill University were asked to participate in the study. Patients were treated by undergraduate students under the supervision of expert prosthodontists. Both the dentists treating the case and the patients were blinded to the type of RPD used. The Principal investigator was responsible for preparing the laboratory prescriptions and sending the final impressions to the dental lab in order to assure blinding of the patient and the treating dentists.

Patients were treated according to standardized clinical procedures. Both dentures were fabricated from one master cast to ensure standardization. The cast was scanned digitally to fabricate the laser-sintered dentures, and then was used to fabricate the cast dentures traditionally using lost-wax casting technique. For each patient, two dentures were fabricated from one final impression; one by casting technique and the other by laser-sintering. Patients were given randomly one denture first and followed-up for 1, 2 and 4 weeks. Then, they were given the second denture and followed-up again. At each follow-up visit, patients filled McGill Denture Satisfaction Instrument. At the end of the study patients were asked which denture they prefer to keep.
