Introduction: Tooth agenesis represents a major challenge for the orthodontist regarding treatment plan and orthodontic mechanics. In general, the treatment possibilities are maintenance/opening of spaces for future rehabilitation with implants and prosthesis or space closure in agenesis areas. Several factors need to be considered during treatment plan. Treatment plan shall provide good aesthetic and functional results, without major consequences for teeth and adjacent structures. Objective: This case report presents the orthodontic treatment of a young patient with Class I malocclusion and agenesis of the maxillary right lateral incisor and mandibular second premolars, treated with space closure with miniscrews anchorage and aesthetic teeth recontouring. It also illustrates a side effect resulting from mesial movement of posterior teeth. Results: Interdisciplinary treatment for agenesis of upper lateral incisor and lower first premolars enabled the achievement of great aesthetics and functional results. Conclusion: The use of mini-implants was essential to allow mesial movement of the posterior teeth without prejudice to the patient profile. However, side effects resulting from the mechanics must be controlled.
