Periodontal status of anterior teeth following clinical crown lengthening by minimally traumatic controlled surgical extrusion.

Background/aims: The number of fractured anterior teeth following trauma has been increasing while not every patient is able to afford a dental implant instead of maintaining the injured tooth. Thus, a tooth conservation solution is required to place an aesthetic and functional restoration without biologic width violation. The aim of this study was to evaluate the effectiveness of minimally traumatic controlled surgical extrusion in fractured anterior teeth crown lengthening by assessing the periodontal status through clinical examination and radiographs.
