Crown lengthening

Crown lengthening


Crown lengthening is a surgical procedure performed to expose a greater amount of tooth structure for the purpose of subsequently restoring a severly decayed tooth prosthetically. This is done by incising the gingival tissue around a tooth and, after temporarily displacing the soft tissue, predictably removing a given height of alveolar bone from the circumference of the tooth or teeth being operated on. Crown lenthening is often performed when decay is present below the gum tissue at bone level. This procedure is indicated in order to save the tooth and prevent an extraction.
