The violation of the biological space can be caused by several factors such as subgingival caries, restorations that extend into the gingival sulcus, root fractures, and cervical root resorptions. Clinically, changes in the biological space can be observed as gingival recession and inflammation, the formation of a periodontal pocket. This condition is diagnosed by interproximal radiography methods using the parallelism technique, and by clinical evaluation through transcellular or transperiodontal probing, measuring the distance between the bone and the margin of the restoration with the aid of a periodontal probe. The clinical crown increase is a periodontal surgical procedure that aims to remove the periodontal support structure to expose healthy tooth structure region above the alveolar bone crest.
