Abstract
Developing Class III malocclusion is considered one of the most challenging orthodontic problems to treat. Class III might be due to mandibular prognathisim, maxillary deficiency or combination of these
components. The realization that maxillary deficiency is so frequently a component skeletal Class III malocclusion, protraction of the growing maxilla if done in the early mixed dentition period, led to promoting maxillary growth
and more normal jaw relationship.
Palatal implant anchorage has been widely used in orthodontic practice.
The palate provides a safe zone with easy access and good quantity of bone.
The anterior region is the thickest part of the palate. Application of surgical mini-plates and mini-screws into the anterior part of the palate offers an option to transmit force directly to the maxilla for maxillary protraction. The present study was conducted to evaluate the treatment effects of
skeletally anchored facemask using surgical miniplates fixed to the palate, and
compare these changes with growth changes of an untreated group.
Forty growing Class III subjects with maxillary deficiency in the early
mixed dentition phase were included in the study. Six patients discontinued
follow up visits and were dropouts. The study was carried out on the remaining 34 patients. These patients were allocated into two groups; in group 1 (n=19)
skeletally anchored facemasks were employed with miniplates placed in the
palate. group 2 (n=15) was an untreated control group. Pre- and posttreatment and observation period cephalometric radiographs were analyzed. The treatment period was 7.79 ± 2.23 months in group 1, and the
untreated control group was observed for 10 months.
