Abstract:
A 15-year-old female presented unilateral Class II molar relation with 90% overbite, retroclined upper central incisors, and impacted lower right canine. Nonextraction treatment was planned to correct deep bite, retroclination of upper central incisors, and unilateral Class II molar relation. Intrusion arch was used to intrude and procline the upper central incisors. Correcting the axial inclination of retroclined incisors caused unlocking of the mandible. This, in turn, leads to simultaneous correction of class II molar relation. The vertical loop was used to disimpact canine. Posttreatment incisors inclination was corrected, bilateral Class I molar relation was achieved, and canine had erupted in its position. The smile arc was improved along with mentolabial sulcus and nasolabial angle.

Abstract:
A 10-year-old female presented with a skeletal Class II relation with 7 mm of overjet, 40% overbite, and bilateral posterior lingual crossbite. Two-phase therapy was planned to correct Class II skeletal relation, overjet, overbite, and to achieve lip competency. Phase I therapy was done with twin-block appliance to advance the retrognathic mandible. Phase II therapy was accomplished with fixed appliance for arch coordination to correct minor displacement and to finalize occlusion. Posttreatment, skeletal Class I relation was achieved. Incisors' inclination was improved, and ideal overjet and overbite with bilateral class I molar relationship was achieved. As the mandible advanced, lip competency, facial convexity, and mentolabial sulcus improved.

Abstract:
Objectives:
To study the gingival biotype and its relation to maxillary and mandibular incisor inclination and its relation to dentopapillary complex.
Materials and Methods:
This cross-sectional study included 150 consecutive patients seeking orthodontic treatment at JSS Dental College, Mysore. Gingival biotype was assessed for maxillary and mandibular incisors using a digital vernier caliper. Maxillary and mandibular incisors' inclination and position were measured using cephalometric analysis. Parameters of dentopapillary complex were recorded from the dental casts.
Results:
The prevalence of thin gingival biotype was 42.66% for maxillary and 39.33% for mandibular incisors. A significant association was found between mandibular incisor inclination and thin gingival biotype, whereas there was no association between maxillary incisor inclination and gingival biotype. There was a significant correlation between gingival biotype and crown length, area of papilla, area of crown, and papilla length with P = 0.001 each.
Conclusion:
Mandibular incisor proclination is associated with thin gingival biotype, whereas no association is found in the maxilla. The correlation between gingival biotypes and dentopapillary complex is confirmed in this study. Evaluation of gingival biotype is of paramount importance during treatment planning for orthodontic patients.
