- Problem With Dentures
- Interventions
- Other: soft lining of complete denture processed by 3 different techniques.
- Registration Number
- NCT05955989
- Lead Sponsor
- Asmaa Nabil Elboraey
- Brief Summary
The bond between the resilient denture liner material and the denture base is essential to improve complete denture accuracy and retention to the underlying ridge. The bonding characteristics between resilient denture reline materials and conventional Polymethyl methacrylate (PMMA) denture base polymers have been evaluated extensively. But with the introduction of digital fabricated complete denture, the bond characteristics between digitally fabricated dentures and denture liner is sparse.
- Detailed Description
Dental prostheses fabricated using different digital technology have become popular in recent years. Computer-aided design and computer-aided manufacturing (CAD-CAM) technology provides two techniques, milled or 3D printed technique which simplified the complex dental laboratory procedures by digitalizing the prosthetic design and automating the manufacturing process. Digitally fabricated prostheses have been reported to have excellent accuracy factor that has been related to favorable clinical performance. However, bone resorption underneath any mucosa supported prosthesis is not avoidable. Resilient liners are required for most complete dentures after 6 to 12 months to improve adaptation to the underlying tissues and to reduce the force transmitted to the edentulous ridge during functionThe bond between the resilient denture liner material and the denture base is essential to improve complete denture accuracy and retention to the underlying ridge. The bonding characteristics between resilient denture reline materials and conventional Polymethyl methacrylate (PMMA) denture base polymers have been evaluated extensively. But with the introduction of digital fabricated complete denture, the bond characteristics between digitally fabricated dentures and denture liner is sparse.
Therefore, the aim of this project is to evaluate the bond strength and effectiveness of denture reline of CAD/CAM (milled and 3D printed ) fabricated complete dentures compared to conventional heat-polymerized denture base.

Group Intervention Description complete denture fabricated by CAD/CAM milled technology soft lining of complete denture processed by 3 different techniques. The patients in this group will receive complete dentures fabricated by CAD/CAM ( Computer aided design/ Computer aided manufacture) method. and they will receive soft lining of the complete dentures after one year. complete denture fabricated by CAD/CAM 3D Printed technology soft lining of complete denture processed by 3 different techniques. The patients in this group will receive complete dentures fabricated by 3D printing ( three dimension) method. and they will receive soft lining of the complete dentures after one year. Complete denture fabricated from Conventional heat curing soft lining of complete denture processed by 3 different techniques. The patients in this group will receive complete dentures fabricated by conventional heat curing method. and they will receive soft lining of the complete dentures after one year.
- Primary Outcome Measures
Name Time Method Assessment of change in occlusal forces during the follow up period. on 3rd month of denture insertion, on 6th month of denture insertion, on the 9th month of denture insertion Assessment of occlusion equilibrium by Occlusense device
Assessment of change in retentive force of the complete denture on 3rd month of denture insertion, on 6th month of denture insertion, on the 9th month of denture insertion assessment of complete denture retention by digital force gauge
- Secondary Outcome Measures
Name Time Method Patient Satisfaction on day one of denture insertion and on the 9th month of denture insertion ( end of the follow up period) a questionnaire was designed containing 5 questions regarding the following parameters: retention, comfort, appearance, phonetics and pain. Increasing the score meaning more patient satisfaction.
