Valarelli FP, Semenara NT, Patel MP, Almeida JF, Freitas KMS. Skeletal open bite Class III compensatory treatment with biofunctional therapy. Int J Case Rep Images 2021;12:101189Z01FV2021.ABSTRACT
Introduction: Class III skeletal malocclusion in adult patients presents mainly two treatment options: the surgical-orthodontic approach or compensatory treatment.
Case Report: In the present report, it was described the case of a 23-year-old male patient who presented skeletal Class III malocclusion associated with anterior open bite. The patient refused surgical-orthodontic treatment. Thus, the compensatory orthodontic treatment was performed with the biofunctional technique, consisting of preadjusted brackets with accentuated palatal torque on the maxillary incisors and accentuated buccal torque on mandibular incisors. This prescription aims to minimize the effects of Class III intermaxillary elastics, promoting more bodily movement than tipping of the anterior segments and improve bone remodeling. The anterior open bite was treated with lingual spurs, differentiated bonding of the accessories and early intermaxillary elastics. After 23 months of treatment, a functional occlusion was observed with bilateral Class I canine and molar relationships, overbite correction, and satisfactory smile esthetics.
Conclusion: The great outcomes indicate that compensatory orthodontic treatment is possible in skeletal discrepancies, with the correct diagnosis and considering patient compliance. The biofunctional technique provided a favorable dental positioning for Class III correction.
