Complete dentures made of a light curing denture base material

Methods: Seventy-four complete dentures (28 upper jaw, 2 lower jaw, 22 upper and lower jaw) were incorporated in 52 patients. 38 dentures were randomly assigned of the new light curing material (study group), 36 were made of the PMMA-based material (control group). Data were collected 4 weeks after insertion (baseline) and after a period of 6 and 12 months in service. Tissue reaction and plaque accumulation (Denture Hygiene Index) were visually evaluated by calibrated investigators. The number of technical complications and aftercare were collected by a standardized evaluation sheet. Patient contentment was determined using a short version of the OHIP for edentulous patients (OHIP-EDENT) and a visual analog scale. Statistical analysis was performed using Mann-Whitney-U-Tests.

Results: The study group showed more plaque accumulation than the control group after 6 and 12 month (p = 0,032). However, the findings for the tissue reaction were comparable in both groups. The study group demonstrated a higher rate of technical complications as fractures or loss of teeth (p = 0,042). After 12 month the patients contentment evaluated with the analog scale was higher for the control group (p = 0,046). No significant differences between the two groups could be found by the OHIP-EDENT.

Conclusions: Complete Versyo.com-dentures can be an alternative for patients with incompatibilities or allergic reactions against PMMA-based products. A certain rate of complications and a better compliance for cleaning the denture should be considered.
