The aims of surgical crown lengthening procedures are to improve prosthetic reconstructions at teeth with limited hard tissue, to prevent periodontal problems and/or to improve esthetics. When planning and performing surgical crown lengthening, it is important to consider not only periodontal and technical aspects but also the gingival profile of the neighbouring teeth. This paper presents the systematic approach starting with the diagnosis and indication to the performed treatments and the obtained results and gives clinical recommendations.
