Abstract: Aim: The aim of this study was to evaluate and compare marginal integrity and axial wall adaptation of provisional restorations fabricated by CAD/CAM with those fabricated manually. Materials and Methods: Thirty provisional crowns were prepared from CAD/CAM, light cure and self cure temporization material. They were sectioned mid bucco-lingually. Marginal integrity and axial wall adaption was evaluated at three different points on a 40x stereomicroscope. Results: Statistical difference was found between the marginal integrity and axial wall adaptation of CAD/CAM crowns when compared to other manually fabricated provisional restorations (P<0.001). Lowest Marginal discrepancy and better axial wall adaptation was found with CAD/CAM followed by Light cure and then self cure. Conclusion: Within the limitations of this study, it can be concluded that CAD/CAM provisional crowns showed better marginal integrity and axial wall adaptation than manually fabricated provisional restorations and thus, can be thought for long term purposes.
