Abstract

Introduction: Patients with dental Class II bimaxillary dentoalveolar protrusion are generally treated by extracting all four first premolars or two first and two second premolars, and retracting the anterior teeth. This case report describes the treatment of an adult female patient aged 21-year-old with bimaxillary protrusion, a Class II canine and class II molar relationship along with lip protrusion.
Materials and Methods: In this patient, the lower right and left mandibular first molar i.e., (3-6) and (4-6) had to be extracted due to extensive caries, also extraction was performed for maxillary 1st right and left bicuspids i.e., (1-4) and (2-4). Mini-implant (1.4 mm in diameter, 8 mm long) were placed in interradicular bone between the maxillary second bicuspids and first molars and mesial to mandibular second molar to allow en-masse retraction of upper and lower anterior teeth.
Results: Overall, miniscrews (TADs) can provide anchorage to produce a good facial profile in cases of dental Class II bimaxillary dentoalveolar protrusion with hopeless mandibular first molars.

Keywords: Miniimplant, Tooth extraction, Tooth movement.
