This manuscript provides a 22-year posttreatment follow-up update on a 19-year-old woman treated with strategic extraction of the maxillary second molars. The patient initially presented with a Class II malocclusion, maxillary crowding, and absence of the mandibular first molars. Two extractions were needed in the maxillary arch, and the extraction of two maxillary second molars was chosen as a treatment option, with distalization of the first molars and retraction of anterior teeth. The results were excellent, with Class I canine and molar relationships obtained, normal overjet and overbite, maxillary and mandibular third molars in occlusion and well positioned, and no significant change in the facial profile. The stability of the treatment results was maintained 22 years after treatment. The correct treatment protocol and biomechanics, excellent patient compliance during active treatment, and the proper retention use were essential for maintaining long-term stability after 22 years of treatment in this patient.
