An Alternative Approach for Space Opening in a Bilateral Maxillary Lateral Incisor Agenesis Patient using Miniplates.

AIM
This case report aimed to present an orthodontic mechanic alternative for space opening in a patient missing maxillary lateral incisors, using miniplates as anchorage, associated with self-ligating brackets.


BACKGROUND
Dental agenesis affects the population causing esthetic and functional damages. The prevalence of missing maxillary lateral incisors should be considered for its significant rate and negative impact on smile esthetics.


CASE REPORT
This treatment was chosen based on the presence of balanced facial pattern, large canine anatomy, the need to improve dental occlusion to prevent further wear, and patient's esthetic complaint. To obtain the results, upper third molars were extracted, and two miniplates were installed to distalize the upper arch with no need for patient compliance or auxiliary devices. Self-ligating brackets were used to reduce friction on posterior teeth, thus facilitating movement with light force application. At the end of 19 months, the patient presented with class I good overbite and overjet, and adequate space for implant and prosthetics; also, good facial esthetic was maintained.


CONCLUSION
When indicated, space opening may provide excellent esthetics and functional results, and even more predictable results when skeletal anchorage miniplates are used to distalize all posterior teeth.


CLINICAL SIGNIFICANCE
Considering the high level of esthetic and functional compromise caused by dental agenesis, the technique hereby described represents a viable mechanic alternative within orthodontic possibilities.
