Severe overjet and deep overbite correction by en masse distalization using lingual appliances and mini-implant Anchorage: two case reports

Abstract

Purpose: The aim of this article is to describe the efficiency and the biomechanics of entire arch distalization with lingual appliances and mini-implant anchorage with two case reports. Material and Methods: The overbite was corrected by lingual brackets and archwires with the advantage of bite plane effect. The severe overjet was eliminated by entire upper arch distalization using mini-implant anchorage. Result: After 20 and 24 months of treatment, normal overbite and overjet were achieved with Class I canine and molar relationship. One-year post-retention records confirmed the stability of the treatment outcome. Conclusion: Mini-implants in combination with lingual appliances may have the possibility of distalizing the whole upper arch in one phase to correct excessive overjet and deep overbite.
