Biologic width recovery: a discussion of the measurements utilized on crown lengthening procedures with osteotomy. RGO, Rev. gaúch. odontol. (Online) [online]. 2013, vol.61, suppl.1, pp. 519-522.

The physiological aspects of the supracrestal gingival tissues, which include gingival sulcus, junctional epithelium and connective tissue attachment have been widely studied in Periodontology, mainly related to crown lengthening procedures with osteotomy. If the biologic width is violated, it is necessary to be recovered. The osteotomy aims to restore the anatomical dimensions of the supracrestal gingival tissues. There are several scientific studies about the optimal distance in the supracrestal gingival tissues recovery, with measures ranging from 3.0 to 5.25. Recent studies have showed a high similarity between the supracrestal gingival tissues of contralateral teeth in the same individual. These facts corroborate the need to review the parameter of 3.0 mm utilized on crown lengthening procedures with osteotomy. This paper aims to discuss, based on the literature, the different measures used on the supracrestal gingival tissues recovery.
