The treatment of areas demanding esthetic requirements, such as maxillary anterior teeth, should take into account the achievement of a healthy, harmonious to the surrounding tissue, and an attractive smile line. In this case report, the smile line, soft tissue and hard tissue morphology, and the anatomy and proportion of the tooth must be considered. In patients with an unesthetic maxillary anterior ratio due to inadequate gingival contour and diastema caused by peg laterals in maxillary lateral incisors, it would be challenging to achieve

an esthetic restoration by orthodontic treatment alone. In such a case, after orthodontic treatment, gingivo-dentofacial compositional diagnosis and analysis, followed by gingivectomy and prosthodontic restoration are needed to improve the interdental mesial/

distal, width/length ratio to achieve a satisfactory aesthetic result. In addition, when improving the tooth proportion of peg laterals by prosthodontic treatment, Porcelain laminate veneer (PLV), which results in less tooth structure loss, reproduction of similar shade to that of the proximal tooth and high transparency, is recommended. This case report demonstrates esthetic improvements by prosthodontic restoration through systematic diagnosis and treatment procedure in patients with an unesthetic maxillary anterior

proportion after orthodontic treatment due to peg laterals in maxillary lateral incisors by

means of two female patients aged twenty years old.
