Esthetic and functional rehabilitation of an impacted maxillary canine and microdontic lateral incisor: A multidisciplinary approach

This case report presents the treatment and 1-year follow-up of a patient with an impacted maxillary canine and microdontic lateral incisor through orthodontic-restorative collaboration. Anterior recontouring is the final step in orthodontic therapy to maximize function and appearance. This case report demonstrates a minimally invasive and direct method of postorthodontic anterior recontouring using an injectable resin composite technique with a digital workflow. Orthodontic treatment involves repositioning the impacted tooth, aligning the microdontic teeth to an ideal position with fixed appliances, and leveling the mandibular and maxillary teeth. In addition, the restorative treatment of microdontic maxillary lateral incisors involves creating a transparent index on a digitally modeled and 3-dimensional-printed model, transferring the design to the target teeth with a highly-filled flowable composite resin. In the esthetic rehabilitation of teeth after orthodontic treatment, the injectable resin composite technique with a digital workflow is a predictable, cost-effective, and minimally invasive treatment alternative. The 1-year follow-up demonstrated successful color and gloss stability, as well as the integrity of the restorative material.
