EasyBOPT: A Digitally Standardized Protocol to Simplify and Reproduce the Biologically Oriented Preparation Technique...

Background: The Biologically Oriented Preparation Technique (BOPT) protocol has demonstrated excellent clinical and biological outcomes in restorations with vertical preparation designs. However, its provisional phase remains highly dependent on the operator's skill. The EasyBOPT (eBOPT) protocol introduces a standardized digital workflow aimed at simplifying this process and enhancing its reproducibility. The primary objective of this study is to describe the eBOPT protocol and to compare its clinical outcomes with the conventional BOPT approach in a prospective case series. Materials and Methods: A case series was conducted including ten patients requiring full-coverage restorations in the maxillary anterior region. The study protocol was registered on 15 July 2024 at ClinicalTrials.gov, with the following registry name: Periodontal outcomes and digital volumetric variation following BOPT restorations, and with the following registration number: NCT06485999. Five patients were treated using the conventional BOPT protocol and five with the eBOPT protocol. Both groups followed identical diagnostic, preparation, and definitive restoration phases, differing only in the provisionalization technique. In the eBOPT group, a digital workflow based on dual scanning (physiologic and retracted gingiva), "best-fit" alignment, and CAD-CAM fabrication of a standardized 45° emergence provisional restoration was employed. Operative time per tooth, gingival healing time, and the need for additional adjustments were recorded. Results: The mean clinical time per tooth was significantly lower with the eBOPT protocol (12.30 ± 1.50 min) compared to the conventional protocol (31.20 ± 2.10 min; p < 0.001). The mean gingival healing time was also reduced with eBOPT (4.4 ± 0.9 weeks) relative to the traditional approach (9.6 ± 1.5 weeks; p = 0.0014). Only the conventional group required additional provisional adjustments (80% of cases; p = 0.048). Conclusions: The EasyBOPT protocol enables faster, more predictable, and less operator-dependent provisionalization while maintaining the biological stability and gingival health achieved with conventional BOPT. This digital workflow simplifies the clinical application of the BOPT concept and enhances its reproducibility.
