Abstract
Patient: The patient was a 45-year-old female with the chief complaint of unpleasantness of maxillary right incisors (21) and masticatory disturbance due to missing lower molars (67), which resulted in an irregular occlusal plane. First, periodontal treatments including orthodontic extrusion of the maxillary right incisors were performed, then the occlusal plane was corrected in the maxillary left molar region. Lastly, occlusal reconstruction was functionally and esthetically performed. The occlusal condition at 10.5 years later indicated good results, maintaining almost the same gingival level as before.
Discussion: Orthodontic extrusion is useful for not only esthetic but also periodontal reasons.
Conclusion: Long-term periodontal success was obtained through orthodontic extrusion and periodontal surgery as preprosthodontic treatment.
