Loss of tooth structure in the esthetic region is a big challenge for restorative dentist as it not only involves the establishment of tooth structure but also complies microesthetics. If the tooth structure is lost near the gingival margin, then the periodontal aspect cannot be overlooked. Surgical crown lengthening and orthodontic extrusion of the remaining tooth structure are two possible treatment modalities for such cases. Which one is best suited depends on the indications for each procedure. This study reports an orthodontic extrusion for the restoration of fractured upper canine. Preference of crown lengthening by orthodontic extrusion over surgical crown lengthening is clarified along the case discussion.

Anchorage in orthodontics is always a challenging situation. Use of mini-screw implants in orthodontics has solved this problem to the large extent. Here is a case of 22 years old male patient with critical anchorage that requires intrusion& retraction of upper incisors and lower left molar protraction which was in end-on relation with upper molar. Case treated successfully using mini-screw implants by simultaneous intrusion, retraction & protraction to achieve class I molar relation and pleasant profile.

Tandem appliance is preferred over face mask mainly because of compliance reasons. In the given case report, clinicians have used tandem appliance for correcting skeletal class III malocclusion patient in later stage of growth. Operators utilized residual growth. Facial harmony was achieved by gaining positive overjet. Adolescent class III malocclusion is challenging to treat. Occurrence of class III malocclusion is just 5% in India. If patient reports in growing stage, clinicians get many relevant treatment options. Lack of knowledge about growth modulation therapy causes loss of growing stage of patients. This situation reduces available treatment modalities. Here is a case of female patient with class III malocclusion who is near completion of her growth; maxillary growth was stimulated in forward direction taking anchorage from overgrown mandible with the help of tandem appliance.
