ABSTRACT Objective:  To evaluate the dentoskeletal short-term effects of rapid maxillary expansion and facemask therapy (RME/FM) in a sample of Class III patients showing different vertical skeletal relationships. Materials and Methods:  Seventy-nine patients (35 females and 44 males) having Class III malocclusion were consecutively treated using RME/FM therapy with application of the protraction force in a downward and forward direction and inclination of about 30° to the occlusal plane. All patients were evaluated at the beginning (T1; mean age, 7.7 years) and at the end (T2; mean age, 9.2 years) of orthopedic therapy and divided into three groups according to their vertical skeletal relationships: normal group (NG), hypodivergent group (HypoG), and hyperdivergent group (HyperG). Statistical comparisons between the three groups were performed on the starting forms (T1), the final forms (T2), and the treatment changes (T1–T2) using the ANOVA with Tukey's post hoc tests. Results:  Favorable modification in terms of maxillary advancement (changes in SNA ranging from 1.4° to 1.8°) and intermaxillary sagittal skeletal relationships (changes in Wits appraisal ranging from 2.5 mm to 3.5 mm) were recorded in all groups. The three groups showed no statistically significant differences in changes in either sagittal or vertical skeletal variables. Conclusions:  The various vertical skeletal features do not influence the short-term outcomes of RME/FM therapy.

The Alt-RAMEC protocol was introduced by Liou in the year 2005. It allows for sutural mobilisation by opening and closing the RME screw for 7-9 weeks. Maxillary protraction after the use of Alt-Ramec (alternate rapid maxillary expansion and contraction) protocol is an efficient method for early treatment of skeletal Class III malocclusion. This case report shows the results of using a hyrax bonded maxillary expander with the Alt-RAMEC protocol to treat a maxillary hypoplasia Class III malocclusion. A 12-year-old patient with skeletal class III malocclusion with anterior as well as the unilateral posterior crossbite was treated using this protocol. CBCT scans were taken before and after expansion. These CBCT scans were used for assessing and analysing the skeletal changes that have occurred after using the AltRamec protocol. The objective of this case report is to assess skeletal changes after using the Alt-RAMEC protocol.

Skeletal Class III is a malocclusion characterized by anterior crossbite as a result of an abnormal skeletal maxillary and mandibular base discrepancy, which involves disharmony of craneofacial skeleton and profile. The preferred management for children having skeletal Class III malocclusion with retruded maxilla and/or prognathic mandible is the use of devices that encourage the growth and anterior movement of the maxilla bone and/or restrict the exessive mandible growth. The orthopedic treatment consisting of a face mask with rapid maxillary expansion (RME) produces the most dramatic results in the shortest period of time. The purpose of this article is to review a quick correction of skeletal class III maloclussion in the primary dentition through a case example with use of a face mask plus rapid maxillary expansion therapy in a 5 year-old male patient due to a combination of retruded maxilla and protruded mandible, in primary dentition, who was treated with a Petit face mask in conjunction with a bonded RME intraoral appliance added with bite blocks. The first evident occlusal outcomes were a clockwise rotation of the mandible, a positive overjet of 3 mm, a correct overbite, a canine Class I relationship, and a bilateral flush terminal plane. After discussing the present clinical case report and the related published literature, we concluded that skeletal class III malocclusions should be treated as soon as the first clinical signs of abnormal craniofacial growth are recognized, during the first years of life.

The orthodontic treatment of Class III malocclusion with a maxillary deficiency is often treated with maxillary protraction either with or without maxillary expansion. The routine procedure for rapid maxillary expansion includes banding on first premolars/first deciduous molars and the permanent first molars. However in some patients who are esthetically very conscious, banding of the first premolar would not be a good esthetic option. So for such circumstances we have designed a modified hyrax splint, which does not need the first premolars to be banded.
