In patients presenting with retroclined incisors, deep overbite, and severe anterior crowding or ectopic canines, the decision between extraction and non-extraction protocols often hinges on soft tissue profile aesthetics, patient compliance, and precise anchorage preservation.
While conventional extraoral headgear and tooth-borne distalization mechanics historically addressed these discrepancies, they frequently introduced undesirable side effects—such as reciprocal premolar mesialization, anterior incisor flaring, and prolonged treatment duration driven by inconsistent patient cooperation.
To overcome the inherent limitations of traditional intraoral distalizers, the integration of temporary skeletal anchorage devices (TADs) with modified appliances has transformed Class II non-extraction therapeutics.
By combining the versatile force system of a Pendulum appliance with direct or indirect miniscrew anchorage in the anterior palate, clinicians can achieve absolute molar distalization while completely eliminating anterior anchorage loss.
This skeletal reinforcement enables bodily distal movement of the maxillary molars, spontaneous premolar drift, and the creation of sufficient arch perimeter to facilitate the eruption and alignment of blocked-out canines without compromising the facial profile.

This clinical case report thoroughly illustrates the orthodontic management of a 12-year-old adolescent patient presenting with a skeletal Class II pattern, convex profile, deep bite, and severe maxillary canine crowding.
The authors demonstrate how a carefully sequenced, non-extraction protocol utilizing a bone-anchored Pendulum appliance supported by two orthodontic mini-implants successfully achieved bilateral Class I molar and canine relationships, leveled the curve of Spee, and restored functional occlusal balance in an 18-month active treatment period.
By reviewing the underlying biomechanics and cephalometric outcomes, this study highlights how modern skeletal anchorage strategies provide a predictable, compliance-free alternative for complex Class II corrections.
