Surgical Crown Lengthening Simplified
Gordon J. Christensen, DDS, MSD, PhD
Unfortunately, surveys show that most general dentists do not include surgical crown lengthening in their practices. Some GPs remove soft tissue using laser or electrosurgery but do not alter bone. This technique works if there is an excess of soft tissue. However, if there is no soft-tissue excess, removal of free gingiva often injures the epithelial attachment, causing gingival and bone recession, inflammation, and an unsightly esthetic appearance. Surgical crown lengthening removes bone and soft tissue. It is not difficult and should be done to allow a ferrule of about 2 mm of sound tooth structure on the cervical areas of a crown prep. The ferrule provides excellent crown retention. Let Gordon, a pragmatic restorative dentist, simplify this procedure for you!
