    Clinical outcomes of the biologically oriented preparation technique (BOPT) in fixed dental prostheses: A systematic review
    (2022) Abad Coronel, Cristian Gustavo; Palacio Sarmiento, Stefany Carolina; Villacis Manosalvas, Jeniffer Adriana; Pradíes, Guillermo; Loi, Ignazio; Esquivel, Jonathan
    Statement of problem: The biologically oriented preparation technique is a concept with a vertical tooth preparation, gingitage, an immediate interim restoration preserving the clot, and a specific laboratory technique aiming to adapt the marginal periodontal tissue to a remodeled emergence profile of the crown. However, the published scientific evidence on this subject is limited. Purpose: The purpose of this systematic review was to analyze whether using the biologically oriented preparation technique leads to improved clinical outcomes in terms of probing depth, gingival inflammation index, gingival marginal stability, and fewer mechanical and biological complications. Material and methods: Recommendations from the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines were used in this systematic review. An electronic search of the MEDLINE/PubMed, EMBASE, Science Direct, Wiley Online Library, Cochrane, and ProQuest databases was made for articles published between March 2010 and July 2021 using keywords. Three reviewers selected and analyzed all articles that mentioned the biologically oriented preparation technique and met the inclusion criteria. Results: A total of 6 articles met the inclusion criteria: 1 prospective randomized clinical study, 1 randomized clinical study, 1 prospective clinical study, and 3 case series. According to these studies, of all the teeth treated with the biologically oriented preparation technique, probing depth (greater than 3 mm) increased in only 2.3%, gingival inflammation was present in 22.8%, gingival recession occurred in 1.7% (decreased gingival stability), and mechanical and biological failures occurred in 4.4% of the teeth. Conclusions: Fixed dental prosthesis treatments performed following the concept of the biologically oriented preparation technique did not increase probing depth and showed a moderate rate of gingival inflammation, lower recession rates, and lower mechanical and biological failures at the 5-year follow-up. The biologically oriented preparation technique appears to be a viable alternative technique for obtaining satisfactory and stable clinical results up to 5 years. Long-term randomized clinical trials are recommended to reach more conclusions about this protocol.

    Flujos digitales en beneficio de una atención integral y complementaria del paciente con necesidades estéticas y funcionales

    Introduction: The digital workflow is defined as a sequence of processes composed of computerized aids that involve: the acquisition of images, computer-aided design (CAD), computer-aided machining (CAM) and post-production of the achieved result. Digital technology in Dentistry, although it is largely associated with CAD/CAM systems, Digital technology in Dentistry, although it is largely associated with CAD/CAM systems, it also involves various devices that today are of daily use in the dental office and that facilitate the virtualization of the patient. Objective: to conceptualize the treatment sequence based on diagnosis, planning, execution and maintenance and its complementation with other procedures, all digitally guided, with positive effects on a patient's oral rehabilitation. Clinical case: 59-year-old male patient, with incisal edge wear, chromatic, aesthetic and functional alterations (absence of anterior guidance) of the upper anterior tooth group from canine to canine, with upper right lateral crown fracture, insufficient crown-root ratio and filling endodontic defect. Guided extraction of piece 1.2 and implant placement were performed, then dental preparations were made from canine to upper canine with chamfer. Esthetic partial restorations in polychromatic feldspathic ceramics were digitally designed. The dental implant was restored with a lithium disilicate feldspathic ceramic milled abutment and a feldspathic ceramic crown was placed. Finally, a precision splint was made and a control was performed at 14 months.
