Temporary anchorage devices for maxillary protraction: Three-dimensional analysis of treatment outcomes.

摘要

The purpose of this pilot study was to describe outcomes in preadolescent maxillary deficient patients treated with a novel technique for maxillary protraction using temporary anchorage devices (TADs). The study was comprised of three sections: (1) comparison of outcomes in 2D to existing reverse pull headgear (RPHG) literature, (2) description of outcomes in 3D from cone beam computed tomography (CBCT) data, and (3) assessment of inter-examiner reliability for the 3D analytic method. Outcomes were assessed for six consecutively completed cases. Maxillary protraction of varying degrees was observed in all cases with minimal dentoalveolar compensation. The magnitude of skeletal changes observed were generally comparable to that which has been reported in the RPHG literature. The 3D analytic method was helpful in describing change over time in growing patients and the inter-examiner reliability of the analysis method was good.
