Relationship of the gum with the finishing line in the carving of previous crowns

Abstract

Prosthetic crowns are a feasible option within fixed prostheses when rehabilitating a tooth in the anterior area due to their excellent aesthetics and superior restorations adaptability. For decades dental crowns have been used with a high rate of success in previous teeth that have suffered destruction in a large part of their structure. However, the preparation and pre-cementation carving generate doubts when choosing the lines of termination, this will be the ideal one and less risky for gingival health. The objective of the research is to contrast the relationship of the gum in the anterior crowns carving by comparing the lines of termination to determine the correct management of the biological space. Materials and methods: This research is based on a descriptive-analytical literature review of 40 scientific articles published in journals indexed between 2018 and 2022. Results: It was determined that subgingival carved lines of termination from 0.5 to 1mm subgingival are less likely to develop gingival inflammation and plaque accumulation, which is not the case with preparations that invade the biological space. Conclusions: The bibliographic information analyzed suggests that the lines of termination are not a real concern for gingival health as long as individualized care is provided for each tooth to be treated from the moment of carving to cementation.
