RESUMEN
The purpose of this paper is to present and discuss a simple and low-cost clinical approach to correct an asymmetric skeletal Class III combined to an extensive dental open bite that significantly compromised the occlusal function and smile aesthetics of an adult male patient. The patient did not accept the idealistic surgical-orthodontic treatment option, neither the use of temporary anchorage devices to facilitate the camouflage of the asymmetrical skeletal Class III/open bite. Therefore, a very simple and inexpensive biomechanical approach using sliding jigs in the mandibular arch was implemented as the compensatory treatment of the malocclusion. Although minor enhancements in facial aesthetics were obtained, the occlusal function and dental aesthetics were significantly improved. Furthermore, the patient was very satisfied with his new smile appearance. Some advantages of this treatment option included the small invasiveness and the remarkably low financial costs involved. Moreover, the final results fulfilled all realistic treatment objectives and the patient's expectations. Results remained stable 5 years post-treatment demonstrating that excellent results can be obtained when simple and low cost, but well-controlled mechanics are conducted.

INTRODUÇÃO: a busca pelo aumento na eficiência dos tratamentos ortodônticos é uma constante em diversas áreas da Ortodontia atual. A realização de corticotomias alveolares pouco antes da aplicação de forças ortodônticas vem sendo sugerida como uma forma de potencializar a movimentação dentária e, consequentemente, o tratamento ortodôntico como um todo. OBJETIVO: o presente artigo revê a perspectiva histórica dessa abordagem terapêutica, apresenta e ilustra com casos clínicos suas principais indicações e, por fim, discute os fundamentos biológicos que justificam sua utilização.
INTRODUCTION: The systematic search for increased efficiency in orthodontic treatment is shared by several areas of orthodontics. Performing alveolar corticotomies shortly before the application of orthodontic forces has been suggested as a method to enhance tooth movement and, consequently, orthodontic treatment as a whole. OBJECTIVE: This article reviews the historical perspective of this therapeutic approach, presents and illustrates with clinical cases its main indications and finally discusses the biological reasons underlying its use.
