Gingival Contour in BOPT: A Review of Provisional Crown Guidance
Abstract: Background and Aims: In prosthetic dental medicine nowadays, there are a lot of challenges to obtain successful treatment with fixed crown restorations in anterior region. The aim is to achieve excellent aesthetic results, which are related not only to the shade, shape and position of the crown, but also to contour and harmony of the surrounding gingival soft tissues. Many clinical studies have found that the design of the crown margin and emergence profile can guide the contour of free gingival margin. This review explores the role of temporary crowns in guiding gingival contour in Biologically Oriented Preparation Technique BOPT. It presents the advantages and principles of this technique and the methods of manufacturing provisional crowns. Methods: The review includes 41 articles from various databases. Results: The results show different working approaches for fabrication of temporary crowns with appropriate emergence profile. Conclusion: The biologically oriented preparation technique (BOPT)offers many advantages, including the ability to modify and reshape the marginal gingiva contour creating new emergence profile of the crown. The BOPT concept ensures long-term stability of gingival tissues.
