ABSTRACT: Background: The management of Class II malocclusion without extractions remains a therapeutic challenge, particularly in borderline cases where esthetic concerns and dentoalveolar compensation must be carefully balanced. Adequate control of lower anterior torque plays a pivotal role in achieving stable and esthetically satisfactory outcomes while avoiding undesirable proclination. Case presentation: This case report describes the orthodontic treatment of an 18-year-old female patient presenting with dental crowding and a skeletal Class II pattern. A non-extraction treatment approach was selected after comprehensive clinical and radiographic assessment. Particular emphasis was placed on the biomechanical control of lower anterior torque throughout treatment. Fixed appliances were used, and treatment mechanics were carefully planned to optimize alignment, overjet reduction, and occlusal relationships while preserving periodontal health. Results: At the end of treatment, satisfactory dental alignment, Class I canine and molar relationships, and improved facial esthetics were achieved. Proper control of lower incisor torque contributed to favorable occlusal stability and avoided excessive proclination. The treatment objectives were met without extractions, and the patient expressed high satisfaction with the functional and esthetic outcomes. Conclusion: This case highlights the clinical importance of lower anterior torque control in nonextraction Class II treatment. Careful biomechanical planning allows clinicians to manage dentoalveolar discrepancies effectively while minimizing risks to stability and esthetics.
