Enhanced effect of combined treatment with corticotomy and skeletal anchorage in open bite correction.
OBJECTIVE
To determine the effects of combined treatment with corticotomy and skeletal anchorage in open bite correction.


METHODS
Ten patients (6 females, 4 males) with ages ranging from 15 to 25 years were involved. All of the individuals received combined subapical corticotomy and skeletal anchorage procedure and intrusion forces of 200 to 300 g were applied on the attachments of each molar and both premolars during 12 to 15 weeks. Mean changes for the measurements for the sample group were evaluated with Wilcoxon signed ranks test.


RESULTS
Significant intrusion of maxillary posterior teeth provided counterclockwise rotation of the mandible and open bite was successfully corrected. SNB angle increased and the ANB angle decreased (P< .05). Significant decreases were noted for vertical skeletal characteristics and overbite increased accordingly (P< .05).


CONCLUSIONS
Our results indicated that the use of combined treatment with corticotomy and skeletal anchorage provided safe and noncompliance intrusion of posterior teeth in a short period and may be regarded as an alternative method for skeletal open bite correction in adults who reject orthognathic surgery.
