Abstract
Crown Lengthening Surgery (CLS) is a common periodontal procedure, but despite its wide use, there is no complete agreement to the desired amount of exposed sound tooth structure and consequently the quantity of crestal bone removal necessary to allow for the reformation of the supra-osseous- gingivae (SOG) or soft tissue height.
For the most part, we have previously based these measurements on different amounts of wanted available tooth for adequate restorability, and a dimension of approximately 3 millimeters (mm) of soft tissue that supposedly will re-develop after surgery. The 3 mm figure is derived from an autopsy study which results show a significant range (from 2.41 mm to 3.23 mm).
Other studies have also provided infomation on the SOG-dimensions but the sanples used and the investigations' results differ. Moreover, it appears that there is no clinical study on healthy individuals without history of periodontitis or absence of attachment loss that offers information on the SOG-dimensions that have included all teeth type types in both maxillary and mandibular arches.
