Tooth preparations for fixed prosthetic restorations can be done in different ways, basically of two kinds: preparation with a defined margin and the so-called vertical preparation or feather edge. The latter was originally used for prosthetics on teeth treated with resective surgery for periodontal disease. In this article, the author presents a prosthetic technique for periodontally healthy teeth using feather edge preparation in a flapless approach in both esthetic and posterior areas with… 
Biologically oriented preparation technique (BOPT) for implant-supported fixed prostheses
A patient of 58 years of age without medical problems came to the clinic due to missing teeth in the upper posterior region and to change the partial fixed prosthesis in the upper anterior area.
Ceramic veneers on central incisors without finish line using bopt in a case with gingival asymmetry
TLDR
The rehabilitation of central incisors with veneers in a patient with gingival asymmetry was described, applying BOPT concepts to correct asymmetry, and a harmoniously integrated restoration with optimal periodontal health was obtained.
Prospective Clinical Study of Zirconia Full-coverage Restorations on Teeth Prepared With Biologically Oriented Preparation Technique on Gingival Health: Results After Two-year Follow-up.
TLDR
Two years after treatment, vertical preparation without finish line produces gingival thickening, margin stability, and optimal esthetics and neither crowns nor FPDs presented any mechanical complications.
Periodontal Behavior and Patient Satisfaction of Anterior Teeth Restored with Single Zirconia Crowns Using a Biologically Oriented Preparation Technique: A 6-Year Prospective Clinical Study
TLDR
Teeth that are prepared with BOPT in the anterior region present good periodontal behavior around the restored teeth, particularly in terms of the stability of the gingival margin and increased gingical thickness.
Minimal invasive microscopic tooth preparation in esthetic restoration: a specialist consensus
TLDR
This article attempts to illustrate the concept, core elements, and indications of microscopic minimally invasive tooth preparation, physiological basis of dental pulp, periodontium and functions involved in tool preparation, position ergonomics and visual basis for dentists, comparison of tooth preparation by naked eyes and a microscope, and comparison of different designs.
Comparative analysis of trueness between conventional and digital impression in dental-supported fixed dental prosthesis with vertical preparation
TLDR
Digital impression with an IOS seems to be a viable alternative to perform zirconia FPD in the BOPT tecbique, being the Trios the most accuracy IOS.
Peri-Implant Tissue Adaptation after Implant Rehabilitation with Shoulderless Abutments with 24 Months of Follow-Up
TLDR
An 11-year-old girl presented with agenesis of the maxillary lateral incisors, and two-piece implants were placed and shoulderless abutments were prepared following the “biologically oriented preparation technique” (BOPT) protocol.

Cement thickness and microleakage under metal-ceramic restorations with a facial butted margin: an in vivo investigation.
TLDR
Ten metal-ceramic restorations with buccal porcelain butt margins and palatal metal beveled margins for periodontally hopeless teeth showed at least a small amount of microleakage, but adaptation of beveling margins proved to be superior to that of shoulder porcelaine margins.
Periodontal conditions and carious lesions following the insertion of fixed prostheses: a 10-year follow-up study.
TLDR
When fixed prostheses are adequately made, and the patient maintains a satisfactory oral hygiene, least damage is likely to be caused to the periodontal tissues when the crown margins are located supragingivally.
Periodontal conditions in patients 5 years following insertion of fixed prostheses. Pocket depth and loss of attachment.
TLDR
When the crown margins were located sub-gingivally there was an increase in Gingival Index scores 2 and 3, in pocket depth, and in loss of attachment compared to a supragingival placement, however, most of the alterations were small.
Clinical and microbiological effects of subgingival restorations with overhanging or clinically perfect margins.
TLDR
Changes in the subgingival microflora after the placement of restorations with overhanging margins document a potential mechanism for the initiation of periodontal disease associated with iatrogenic factors.
Relationship of crown margin placement to gingival inflammation.
Fundamentals of fixed prosthodontics
TLDR
The foundations of fixed prosthodontics are studied in detail in order to establish a clear picture of the role of EMT in the human Avatar.
