This lecture will provide an in-depth exploration of the Biologically Oriented Preparation Technique (BOPT), focusing on the comprehensive approach from case selection to final restoration. Initially, the criteria for selecting suitable cases for vertical preparations will be addressed, emphasizing clinical indications such as periodontal health, tissue biotype and anatomical considerations that contribute to successful outcomes.
The step-by-step preparation process will be thoroughly examined, detailing the techniques required to achieve precise and effective results. This includes the elimination of the traditional shoulder margin and the creation of a finish line that promotes better gingival adaptation and stability. Special attention will be given to the integration of diode lasers for soft tissue management, highlighting how laser technology ensures precise gingival troughing, enhanced hemostasis and reduced bacterial load, which collectively result in clean, contamination-free margins and promote faster healing.
The incorporation of digital impressions will be discussed, showcasing their superior accuracy and efficiency compared to traditional methods. Participants will gain insights into the digital design and milling process, understanding how CAD software aids in the modeling of the prosthetic emergence profile and the subsequent fabrication of custom-fit restorations using milling machines. Last but not least, the material of choice for BOPT will be discussed in detail with a focus on the properties and benefits of dental materials such as zirconia, lithium disilicate and advanced hybrid composites.
