The present paper describes 4 clinical cases of Hellman dental age III A group of functional Class III malocclusion in which the horsehoe appliance was applied to obtain normal anteroposterior relationship between jaws. What is the most noteworthy in the result from the use of this appliance is that minimum down and backward rotation during backward repositioning of the mandible is noticed and the excellent retentive property in itself makers allowance for effective orthopedic correction in mixed dentition with anterior crossbite.

The aim of this report is to present the treatment of a 14-year-old boy with scissors-bite. Mandibular symphyseal distraction osteogenesis (MSDO) with tooth-supported distractor was performed to expand the mandible, and intermaxillary cross elastics were used. The mandible was expanded approximately 9 mm. Asymmetric widening was done by using cross elastics and MSDO simultaneously. The buccal crossbite was corrected successfully. After a 2-year observation period, widening of the mandible using this procedure was judged to be stable.

Face mask is an extraoral appliance which used to protract maxilla, and can help in the correction of moderately severe class IlI malocclusions by the anterior displacement of the maxilla and maxillary dentition, and possibly restricting or changing the direction of the growth of the mandible. In three cases the results were followed. 1. Anterior crossbite was corrected 2. Maxilla & maxillary dentition were displaced forwardly. 3. Lingual tipping of the mandibular incisors, and backward & downward rotation of mandible were performed. 4. Acceptable improvement in the class III profile was performed.

A girl aged 16 years and I month, had a severe Angle's class III malocclusion, characterized by a retarded and constricted maxilla, anterior and posterior crossbite. This patient underwent extraction of two lower Ist premolar. After extraction, author placed multibanded system in lower dental arch to change the long axis of anterior teeth and delivered removable appliance with Coffin spring in the upper dental arch to expand dental arch. After 13 months, anterior & posterior crossbite was corrected and this patient's profile was improved. Superimposition of pretreatment and posttreatment cephalograms upon the SN line registered at S showed backward downward rotation of the mandible and retrusion of lower lip.

The patient, 8 years female, complained of crossbite of anterior teeth and prognathism of mandible. There was lingual tipping of upper lateral incisor in teeth lining. Cephalometric analysis revealed normal in maxilla, but forward relation to standard, so daignosised as skeletal class III case. Crossbite of anterior teeth was corrected by means of CIII elastics under multibanded system. Space for eruption of canine was regained by means of E.O.A. After 2 years and 7 months, she gained good interdigitation of buccal segments of attractive facial profile.

This paper presents 2 clinical cases of facial asymmetry resulted from vertical asymmetry of the maxilla and unilateral hyperplasia of the mandibular condyle. Both patients, a 27 year 4 month old female and a 17 year 1 month old male, had a anterior crossbite with deviated dental midline and a concave profile. Both cases were treated with orthodontic and orthognathic procedure. The following results were obtained; 1. The facial asymmetry was favorably corrected. 2. The concave profile was improved. 3. The anterior crossbite was corrected. 4. The upper and lower dental midlines against the facial midline were corrected. 5. The functional overbite and overjet were established.

Condylar hyperplasia is a self-limiting condition characterized by a slowly progressing, enlargement of the mandible that results in facial asymmetry and a crossbite malocclusion. The facial asymmetry, open bite or crossbite, and radiographic evidence of an enlarged condyle confirm the diagnosis of condylar hyperplasia. The etiology of the condition is unknown. This condition usually first becomes apparent during the second decade of life, when one condyle continues to grow while the other is no longer active. Radiographically, the condyle may appear enlarged or the neck of the condyle maybe elongated or both may occur, Sometimes, however, no radiographically demonstrable condylar abnormality will be noted. Surgical correction with subcondylar osteotomy is the treatment of choice. We have observed two cases of condylar hyperplasia occurred in the left mandibular condyle of 24-year-old and 35-year-old women. We obtained that two cases were shown the followed results; 1. Clinically, both cases was unilaterally developed on C/C area, with temporomandibular disorders and pain, facial asymetry and malocclusion. 2. Radiographically, hyperplastic mass confined to the condyle. 3. Histopathologically, these cases shown increased hypertrophic region in parts, and lamellated bone with irregular trabeculae.
