Abstract
Crown lengthening is a surgical procedure aimed at removal of periodontal tissue to increase the clinical crown height. As a restorative dentist using this technique of crown lengthening, one needs to have an understanding of biological width, indications, technique, as well as some possible limitations. The authors aim to discuss these concepts in order that the restorative dentist can use crown lengthening as part of an overall treatment plan in a controlled and predictable manner, taking into account biological factors.
