Summary
Visible light-cured resin (VLCR) complete dentures showed higher plaque adhesion and required more repairs than conventional poly(methyl methacrylate) (PMMA) dentures. Patients need good oral hygiene and increased aftercare for VLCR dentures.
Area of Science:
- Dental Materials Science
- Prosthodontics
- Biomaterials Engineering
Background:
- Conventional complete dentures are typically fabricated from poly(methyl methacrylate) (PMMA).
- Visible light-cured resin (VLCR) offers an alternative material for denture fabrication.
- Comparative data on the clinical performance of VLCR versus PMMA dentures is essential.
Purpose of the Study:
- To compare plaque adhesion, tissue reaction, and technical complications between complete dentures made from VLCR and PMMA.
- To evaluate the long-term clinical performance of VLCR dentures in relation to PMMA dentures.
Main Methods:
- A stratified randomized cohort study involving 52 patients and 74 complete dentures (38 PMMA, 36 VLCR).
- Double-blinding of investigators and patients regarding the denture base material.
- Assessment of plaque adhesion, tissue reaction, and technical complications at baseline (4 weeks) and at 6, 12, and 24 months post-insertion.
Main Results:
- VLCR dentures exhibited significantly higher plaque adhesion at 6, 12, and 24 months compared to PMMA dentures.
- Tissue reaction was comparable between VLCR and PMMA denture groups.
- VLCR prostheses required significantly more repairs, with a 50% increase in aftercare sessions over 24 months for VLCR compared to PMMA.
Conclusions:
- Patients using VLCR complete dentures require diligent oral hygiene practices to manage biofilm accumulation.
- Increased frequency of aftercare and maintenance should be anticipated for patients fitted with VLCR dentures.
- VLCR presents a potential alternative for patients with allergies to residual monomers or benzoyl peroxide found in PMMA.
