Abstract
Clinical crown lengthening procedure would be an effective method for overcoming adverse clinical condition such as short abutment length. There are three kinds of methods in clinical crown lengthening, those are, surgical crown lengthening, orthodontic extrusion and surgical extrusion. Clinicians have to try their best to choose a proper method among those for favorable results. This report aims to review the considerations in each method with various cases and to suggest a decision flow for appropriate selection.
