This case report describes the treatment of one patient with maxillary anterior spacing, caused by bilateral lateral peg-shaped incisors, using a planned sequence of multidisciplinary approaches for esthetic treatment. An asymmetrical gingival line was visible when the patient smiled. To evaluate the desired gingival level and the proportion of restoration to be made using the recurring esthetic dental (RED) proportion method, a diagnostic wax-up model was fabricated. Esthetic crown lengthening corrected the gingival line. RED proportion analysis suggested minor tooth movement prior to any restoration. Two weeks' use of an orthodontic removable appliance with finger springs achieved the proper dental proportion. Home whitening was prescribed for 2 weeks, with an additional 2-week waiting period to ensure tooth color stability. Resin composite treatment corrected the mesial contour of the maxillary canines and reduced the space between the canines and lateral incisors. Final restoration was obtained by placing ceramic veneers on the lateral peg-shaped incisors. The esthetic treatment achieved excellent results; after veneer cementation, the patient exhibited greater confidence with a new smile.


Esthetic dental treatment requires various disciplines to achieve the treatment goal. This case report is an example of well-planned sequences of treatment from the beginning to complete treatment. By conservative and practical treatment approaches used in this case, the clinician will be able to manage to obtain the highest result of esthetic treatment.
