A Hybrid Approach to Class II Correction: Clear Aligner Therapy Combined with Temporary Anchorage Device-Supported DistalizationNAM-KI LEE DDS, PhD, YOON-AH KOOK DDS, MSD, PhD, CHRISTINE HONG DMD, MS, TAE-HYUN CHOI DDS, PhDThe authors describe the use of clear aligners with a modified C-palatal plate and palatal retraction arch to achieve en masse maxillary distalization in an adult with Class II malocclusion and anterior open bite. Class III elastics tip back the mandibular molars to relieve crowding without incisor flaring, showing how skeletal anchorage extends what aligners can accomplish. |

An Integrated AI Platform for Orthodontic Diagnosis and Treatment PlanningMOHAMMED H. ELNAGAR DDS, MS, PhD, FLAVIO SANCHEZ DDS, MS, SERGIO SAMBATARO DDS, MS, PhD, TERRY SELLKE DDS, MS, BUDI KUSNOTO DDS, MSAn AI platform combining diagnosis, treatment planning, staging, and outcome simulation in a single workflow, with orthodontist verification at each critical stage, is applied to a 12-year-old patient with moderate crowding, illustrating how AI can streamline case preparation while keeping clinical decisions in the orthodontist’s hands. |

PEARLSInnovative Force Delivery for Posterior Segment MesializationBASIL M. MUMTAZ BDS, FOrth RCSA crimpable hook on the working archwire, rigidly ligated to an anterior temporary anchorage device, allows power-chain mesialization of the posterior segment while avoiding the soft-tissue trauma of direct transgingival force application. The technique offers a simple, patient-friendly option for TAD-anchored protraction. |

CASE REPORTHemisection of a Fused Maxillary Central Incisor with a Supernumerary Lateral Incisor in a Patient with Significant Maxillary CrowdingMARIA FERNANDA LUNA MONTES DDS, MEHRAN ABEDI DMD, MDentSc, FLAVIO A. URIBE DDS, MDentScThe authors describe the hemisection of a fused maxillary central incisor and supernumerary lateral incisor in an 11-year-old patient, with calcium hydroxide sealing of a communicating lateral canal to preserve central incisor vitality and premolar extraction allowing a lingually displaced lateral incisor to self-correct and an impacted canine to be guided into the arch. |
