Although impaction of a permanent tooth is rarely diagnosed during the mixed dentition period, an impacted central incisor is usually diagnosed accurately when there is delay in the eruption of tooth. In this article, the impacted incisor was moved into it's proper position with surgical exposure and orthodontic traction, after which it showed good stability.

This report describes the multidisciplinary phasewise treatment of a 20-year-old female patient having unilateral right TMJ bony (true) ankylosis whose mouth opening was restricted to 2 mm and mandibular retrognathism; additionally, she was also suffering from speech problems, snoring, difficulty in breathing, and low level of self-esteem and self-confidence. Bilateral gap arthroplasty and temporalis myofascial graft interpositioning through preauricular approach were done in surgical phase followed by the aggressive jaw physiotherapy in postsurgical period. Oral prophylaxis and restorations were followed by the fixed orthodontic therapy to resolve bimaxillary protrusion. Advancement sliding genioplasty was performed to enhance the chin button. Speech therapy and psychological counseling were also performed from time to time to boost up the self-esteem and self-confidence. At the end of treatment, facial esthetics was improved considerably and patient got over the impact of disfigurement, impaired functions, and psychosocial stigma. Rationale to use the multidisciplinary team approach in treatment of such cases is discussed.

The MES and MD both decrease as the angulation of mini-screw loading increases, with increasing load differences occur in MD but the MES remains similar, whilst differences were observed in both MES and MD as CBT increased.

Malocclusion such as impacted tooth is not uncommon. Many approaches with various auxiliary springs have been reported in literature till date for correction of such malocclusions. They had biomechanical, retentive and stability drawbacks inherent in their designs. This article presents the innovative approach for orthodontic correction of impacted tooth, especially with light force appliance, i.e. Begg's appliance, where round wires in round molar tubes are used throughout treatment. A versatile auxiliary orthodontic spring (VAOS) is fabricated in the 0.018 inch Australian stainless steel round wire, which may be anchored on round molar buccal tube, and desirable force vector may be applied in any of the three dimensions. Fabrication and its clinical application are discussed.

In severely protrusive patients, skeletal anchorage from miniscrew is often used to avoid anchorage loss with preferred miniscrew location near centre of resistance (Cres) of posterior teeth. Biomechanical requirement for directing retraction force towards Cres of posterior teeth demands the insertion of miniscrew in loose mucosa, where risk of infection and failure increases. In addition, undesirable biomechanical side effects on anterior and posterior segments may be possible in all three planes, when continuous arch sliding mechanics are installed with miniscrew anchorage. This paper describes technique of molar-stabilizing power arm (MSPA) for simultaneous intrusion and retraction of anteriors with miniscrew placement at attached gingiva between 1st molar and 2nd premolar. Advantages of this technique include (i) the need of miniscrews placement in loose mucosa apically near the Cres of the posterior teeth is eliminated, (ii) the risk of infection and miniscrew failure is lowered since the miniscrew is placed in attached gingiva rather than the loose mucosa, and (iii) by adjusting vertical length or replacing MSPA, alteration of the retraction force vector is possible in all three planes; thus, need of removal and repositioning of the miniscrew (e.g., in correction of occlusal cant) can be eliminated.
