Interventions

• Traditional Complete Denture Fabrication — PROCEDURE
  Conventional complete denture fabrication performed using standard clinical procedures, including preliminary impressions, custom tray fabrication, border molding, final impressions, record base and wax rim fabrication for recording occlusal vertical dimension and maxillomandibular relationship, tooth try-in appointment, denture processing, delivery, and post-insertion adjustments. All materials used are FDA-cleared and routinely utilized in standard dental practice.
• Easdent Digital Complete Denture Fabrication — PROCEDURE
  Complete denture fabrication performed using the Easdent digital complete denture workflow. This technique incorporates 3D-printed trays fabricated from FDA-cleared medical-grade denture tray or try-in denture materials. The trays are designed with standardized tooth positioning and retention features to facilitate recording of esthetics, occlusal vertical dimension, and maxillomandibular relationships using conventional impression materials. Subsequent clinical and laboratory procedures follow standard denture processing methods, including denture fabrication, delivery, and post-insertion adjustments.

Study Details

This study is a randomized, single-blinded clinical study conducted in the predoctoral clinic at Rutgers School of Dental Medicine. The purpose of this study is to compare a traditional complete denture fabrication technique with the Easdent digital complete denture workflow. The Easdent technique is a modification of the conventional method and utilizes FDA-approved materials and 3D-printed trays designed to record teeth position, jaw relations and impression information. Participants who require new dual-arch complete dentures will receive dentures fabricated using both techniques. The order of fabrication and delivery will be randomized. Clinical chair time, number of appointments, and total treatment time will be recorded. Patient-reported outcomes will be assessed using a modified OHIP-EDENT survey and preference questions after completion of both dentures. Student participants will also complete surveys evaluating learning experience and clinical usability. The study does not evaluate the safety or effectiveness of a drug or investigational device. All materials used are FDA-cleared and routinely used in clinical practice. The overall aim is to evaluate efficiency, patient satisfaction, and educational usability of the two denture fabrication workflows.
