Manejo del espacio biológico y su relación con la preparación de coronas dentales. Revisión de la literatura.

Abstract

Introduction: The biological space is the dentogingival junction formed by junctional epithelium and connective tissue. It is very important to know your measurements, because your distance must always be respected when performing a prosthetic treatment such as a dental crown. Objective: Describe how the biological space is managed during the entire procedure that involves the preparation of a dental crown. Materials and methods: The present research work corresponds to a systematic review study with a qualitative approach, the literature search was carried out using metasearch engines, Pubmed, Elsevier, Dialnet and Science Direct. 1208 articles were obtained on the management of biological space and its relationship with the preparation of dental crowns. Only 39 articles met the proposed inclusion criteria. Results: The articles obtained were divided by variables, the information collected from each article was analyzed and their results were attached, only the most relevant information of each variable was included to later continue with the qualitative analysis with a descriptive design of each of them. It was indicated that the correct management of the biological space during the entire procedure that involves the preparation of a dental crown such as the design of the margin, the elaboration of the finishing line, the gingival retraction, the elaboration of provisionals and the cementation of the crown, will lead us to a good rehabilitative treatment.Conclusion: For a good rehabilitation treatment, it is necessary to respect the average dimensions of the connective tissue and the junctional epithelium. A poor management of the biological space can produce pathological alterations with serious complications.
