anterior esthetic restoration accompanied by gingivectomy of patient with unesthetic tooth proportion of maxillary anterior teeth: a case report

Sang Yeon Han1, Jonghyuk Lee1*, Seok Yeun Choi21Department of Prosthodontics, College of Dentistry, School of Health Science, Dankook University, Cheonan, Republic of Korea2Jangbaek Dental Laboratory, Seoul, Republic of Korea

The maxillary anterior teeth play an important role in esthetics. The esthetic of maxillary anterior teeth is closely related to tooth morphology and also harmony with gingiva. Precise diagnosis and treatment plan are essential to satisfy patientโ€™s demand, and sometimes surrounding soft tissue management is involved to achieve the goal. Gingivectomy can be considered as one method to make esthetic restoration possible. As well as esthetics, function has to be considered in maxillary anterior teeth restoration. Definitive cast of abutment and diagnostic cast waxed up labially were superimposed with model scanner, so can provide former comfortable occlusion. This case report demonstrates functional and esthetic improvements of two patients through gingivectomy and the data of superimposed image of casts. (J Dent Rehabil Appl Sci 2018;34(3):208-17)
