ABSTRACT
The accurate positioning of the fixed lingual bonded retainer wire is one of the challenging processes in bonding fixed retainer. Though several methods have been introduced to stabilize the lingual bonded retainer, each technique has an inherent draw back. To overcome this we have designed a customized clip which is similar to Kesling Seperator to aid in accurate and precise positioning of lingual retainer wire.

A displaced orthodontic elastic separator was proposed as being the source of a gingival abscess that progresses to severe bone loss and exfoliation in a healthy adolescent patient with sound periodontal status prior to commencement of orthodontic treatment. After one year of undergoing orthodontic treatment, the patient presented with dull pain and mobility in the left upper permanent molar for which there was no apparent etiology. On clinical examination the patient had gingival inflammation, associated with a deep pocket and severe mobility (Grade III) in relation to the same teeth. Radiographic examination ofan Orthopantomogram (OPG) and IntraOral Periapical Radiograph (IOPAR) revealed a chronic periodontal abscess with severe necrosis of the periodontal ligament and severe alveolar bone loss. On curettage it was found that there was orthodontic elastic separator which was displaced sub gingivally. Active orthodontic forces were temporarily removed and splinting was done. 6 month follow up showed no mobility and significant improvement of alveolar bone height.

Standard Quad helix can be used to correct unilateral and bilateral dento alveolar posterior cross bite till first permanent molar. Correcting the second molar cross bite with quad helix is very difficult which requires fixed orthodontic attachment. To overcome this problem we have designed a Penta-V helix- a modified quad helix in correcting bilateral dentoalveolar posterior cross bite up to second molar.

The goal of early treatment of Class III malocclusion isfocused on providing a more favourable environment for normal growth and on improving the psychosocial development of the child by improving the facial appearance. Rapid palatal expansion with maxillary protraction and face mask has provided a predictable and effective approach to managing the treatment. We are presenting a case report of a growing Class III treated using maxillary protraction therapy, (Rapid maxillary expansion using bonded RME appliance, to loosen the nasomaxillary sutures and Petit face mask with bonded occlusal splint to unlock the maxilla). With early intervention, patient compliance is much better, most of them achieving overcorrection in less than a year. Close monitoring and follow up was done for 5 years to ensure stability of the treatment, and there was no relapse tendency.
