Abstract

Closure of interdental spaces using proximal build-ups with resin composite is considered to be practical and conservative. However, a comprehensive approach combining two or more treatment modalities may be needed to improve esthetics. This case report describes the management of a patient with multiple diastemas, a peg-shaped lateral incisor and midline deviation in the maxillary anterior area. Direct resin bonding along with orthodontic movement of teeth allows space closure and midline correction, consequently, creating a better esthetic result.

  Figure 2 Diagnostic cast. (a) Frontal view; (b) Side view, left; (c) Side view, right; The patient showed Angle class I malocclusion with normal overjet (2 mm) and overbite (2 mm).

  Figure 4 Orthodontic tooth movement. (a) A 0.16 × 0.22 inch TMA wire was used for arranging the teeth; (b) An open coil spring was inserted between right central incisor and right lateral incisor for mesial movement of right central incisor.

  Figure 5 Midline correction and re-distribution of interdental spaces after minor tooth movement. Through the movement of both central incisors to the left, midline was corrected and interdental spaces were re-distributed.

  Figure 6 Diastema closure with an interdisciplinary approach. (a) Preoperative photograph; (b) Postoperative photograph. Interdental spaces were closed and maxillary midline was corrected with a combination of restoration and minor tooth movement.
