Maxillary protraction using a hybrid hyrax-facemask combination

BACKGROUND The aim of this in study was the evaluation of treatment outcomes after using a hybrid hyrax-facemask combination in growing class III patients. METHODS Treatment of 16 children (mean age 9.5±1.3 years) was investigated clinically and by means of pre- and post-treatment cephalograms. Changes in sagittal and vertical, and dental and skeletal values were evaluated and tested for stat...

Comparison of two maxillary protraction protocols: tooth-borne versus bone-anchored protraction facemask treatment

BACKGROUND Protraction facemask has been advocated for treatment of class III malocclusion with maxillary deficiency. Studies using tooth-borne rapid palatal expansion (RPE) appliance as anchorage have experienced side effects such as forward movement of the maxillary molars, excessive proclination of the maxillary incisors, and an increase in lower face height. A new Hybrid Hyrax bone-anchored...

Wear-time recording during early Class III facemask treatment using TheraMon chip technology.

Successful intervention in a developing Class III malocclusion with facemask protraction therapy depends on a patient's ability to adhere to the recommendations for duration of appliance wear. In this article, we report the introduction of a novel approach for tracking of the duration of application of a protraction facemask, with the incorporation of a "FaceMon" sensor (TheraMon, microelectron...

Optimal force for maxillary protraction facemask therapy in the early treatment of class III malocclusion.

BACKGROUND The facemask is used to treat early class III malocclusion, in combination with expansion therapy. There is a great deal of controversy in literature regarding the effectiveness of protraction facemask treatment as studies report results anywhere from considerable changes to lack of any maxillary improvement. This controversy may be due to the fact that the process of placing the ort...
