Core Tip
Core Tip: This case report highlights a non-surgical, dual-phase approach for treating class II division 1 malocclusion with impacted maxillary canines in an adolescent patient. A modified twin block appliance enabled simultaneous mandibular advancement and active canine traction, streamlining treatment and improving outcomes. The innovative appliance design reduced the need for additional anchorage, shortened treatment time, and enhanced facial and dental aesthetics, demonstrating a practical alternative to more invasive or prolonged treatment strategies.
