Objective:
To clinically evaluate a visible light-cured (VLC) resin composite system for long-term provisional and esthetic diagnostic restorations, fabricated using indirect techniques.
Methods:
One-hundred and nine teeth were restored in 31 patients. Preoperational impressions were used to create VLC resin composite restorations (Radica) using indirect techniques. Restorations were relined as necessary and placed using various provisional cements at a follow-up appointment, subsequent to preparation of the teeth. Both fabricating laboratory technicians and placing dentists rated the restorations for acceptability in esthetics, marginal fit, occlusion, and functionality in various stages of provisionalization.
Results:
All restorations (100%) were rated acceptable for esthetics prior to relining. After relining, a majority (93-100%) of restorations were rated acceptable in esthetic and functional criteria. At the placement of the permanent restoration, a majority (96-100%) of restorations were rated acceptable in esthetic and functional criteria. Terms of service ranged from two to seventy-six days.
Conclusion:
In combination with in vitro results, the clinical performance of the Radica VLC system for provisionalization and esthetic diagnostic restorations was judged to be acceptable. The system offers esthetics that are superior to conventional provisional restorations, and should be a valuable option to practitioners considering longer-term provisionalization in complex cases.
