Indirect bonding is done by placing the brackets on a model in the laboratory and using a template or tray to transfer the laboratory positioning to the teeth. The advantages of this technique are 1. decreased chair time 2. less patient discomfort 3. accuracy of a attachment placement 4. good adaptation of attachment to tooth contour 5. occlusal relationship of brackets and opposing teeth can be checked The disadvantages of the technique are 1. complex laboratory procedure 2. sometimes difficult on very short clinical crowns 3. teeth with crowns, large buccal restoration will not bond 4. may not be fitted close, if poor adaptation 5. likely to be disturbed setting Several indirect bonding techniques have proved reliable in clinical practice. However, they differ in the way the brackets are attached temporarily to the model, the type of transfer tray or other mechanism used, the adhesive or sealant employed, whether segmented or full bonding used, and the way the transfer is removed so as not to exert excessive force on a still maturing bond.

10years and 8 months old patient, who had been wearing Milwaukee brace for 5 months, was treated by multibanded system without extract on. She complianed severe protrusion and interdental spacing of upper anterior teeth. Cephalometric analysis revealed short anterior facial height, infraclusion of the lower first molars and severe profrusion of upper and lower anterior teeth. During orthodontic treatment Milwaukee brace was replaced by TLSO, so the orthopedic force on the dentofacial region was eliminated. After 2 years and 3 months, she gained raised bite, increased interincisal angle, salient reduction in the protrusion of upper central incisals with agreeable overjet, complete obliteration of interdental spacing and reduction of protrusion of upper and lower lips.

A girl aged 13 years 1 month, had a Angle's Class 1 malocclusion, characterized by severe aterior crowding, high canine, and loss of the upper and lower left first molars on account of dental caries. This patient underwent ${\frac{4}{4}}$extraction and multibonded system was used. After 20 Months, anterior crowding and high canine was corrected, and the extraction space as closed on both arch. The upper and lower left 2nd molars occupied the first molar spaces instead of the first polars. After 6 Months from debanding, band spaces were disappeared and the third molars were upting normally.

The patient, 16 years female, complained of anterior cross-bite and retrusion of maxilla. Mandibular incisors occluded labially to maxillary incisors. Normally developed mandibular arch in normal elation to facial line, S-N-Pog was within normal range. Cross-bite of anterior teeth was corrected by means of Class III elastics under multibanded system. Space for alignment of crowding of upper anterior teeth was regained by means of cervical headgear and sliding yoke. She gained good alignment of anterior teeth and attractive facial profile after 2 years.

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 case report presents the orthodontic treatment of a 25-year-old patient with skeletal Class II and severe maxillary arch crowding, moderate mandibular arch crowding, anterior crossbite, and a missing lower incisor. He was treated with molar distalization using a modified C-palatal plate and temporary anchorage devices to create sufficient space for retraction. The total treatment duration was 21 months. After treatment, his occlusion and smile esthetics showed significant improvement. The modified C-palatal plate represents a treatment modality that enhances the prospects of non-extraction treatment and reduces the need for extraction.

Craniofacial sutures absorb the stress transferred to skull. It was reported the cells of craniofacial sutures respond to exogenetic factors to be involved in growth control mechanism. In this study, we constructed a finite element model composed of cortical bone, cancellous bone, suture, PDL, and teeth by using CT images of a growing patient, simulating maxillary expansion to evaluate the effects of the thickness of sutures and type of maxillary expansion appliance on stress distribution in circummaxillary sutures.

The patient,20 year-old female, complained of anterior open bite. She had tongue thrusting habit and suffered from maxillary sinusitis since 12-years old. Cephalometric analysis revealed slightly forward relationship in maxilla, but normal in mandible. The anterior open bite was corrected through retraction and extrusion of anterior segment and mesial movement of posterior segment under multibanded system after extraction of 4-first premolars. After 2 years and 3 months, she gained ideal overbite, overjet and good interdigitation of buccal segment.

This present paper describes 3 clinical cases which were treated with Bioprogressive mechanism. Each patient has shown a deficient maxilla combined with prognathic and steep mandible. The purpose of treatment was planned to obtain the forward growth of maxilla and redirectioning of mandibular growth. The most noteworthy approach in the treatment was the application of Cl III intermaxillary elastics with upper protraction utility arch immediately after rapid maxillary expansion. In the analysis of the data obtained from pre- and post treatment lateral cephalogram, the result achieved by this method is very favolable to the correction of anteroposterior relationship of maxilla and mandible.

For successful surgery-first approach, accurate prediction of skeletal and dental changes following orthognathic surgery is essential. With recent development of digital technology using computer-aided design/computer-aided manufacturing (CAD/CAM) technology, attempts to provide more predictable orthodontic/orthognathic treatment have been made through 3D virtual surgery and digital tooth setup. A clinical protocol for the surgery-first orthognathic approach using virtual surgery is proposed. A case of skeletal Class III patient with facial asymmetry treated by the surgery-first approach using digital setup and virtual surgery is presented. Advantages and limitations of applying CAD/CAM technology to orthognathic surgery are discussed.
