Multidisciplinary Treatment of Skeletal Class III Malocclusion with Orthognathic Surgery: Two Case reports

Abstract

Objectives: This case report presents the treatment of two patients with skeletal Class III malocclusion, performed in collaboration with orthodontics and surgery. Case: The main complaint of our patients is negative facial aesthetics; it was observed that it had a concave profile in the extraoral examination, and the right and left canine and molar relationships were Class III on intraoral examination. In the treatment plan, following leveling and decompensation in the lower and upper dental arch with fixed orthodontic treatment, in the first case, 6 mm mandibular set back was performed with sagittal split ramus osteotomy; in the second case, bimaxillary orthognathic surgery (4 mm maxillary advancement ve 4 mm mandibular set-back) was performed. Conclusion: With orthodontic treatment performed after surgery, the occlusion was corrected by bringing the teeth to their proper positions, and at the end of the treatment, a ideal soft tissue with skeletal and dental Class I relationship was achieved.

İskelet Sınıf III Maloklüzyonunun Ortognatik Cerrahi ile Multidisipliner Tedavisi: İki Olgu Sunumu

Abstract

Amaç: Bu olgu sunumu, iskeletsel Sınıf III maloklüzyonlu iki hastanın ortodonti ve cerrahi işbirliği ile yapılan tedavisini sunmaktadır. Olgu: Hastalarımızın temel şikâyeti olumsuz yüz estetiğidir; ekstraoral muayenede içbükey bir profile sahip oldukları, ağız içi muayenede sağ ve sol kanin ve molar ilişkilerinin Sınıf III olduğu görülmüştür. Tedavi planında sabit ortodontik tedavi ile alt ve üst dental arklarda seviyeleme-hizalama ile dekompansasyon yapıldıktan sonra ilk olguda sagittal split ramus osteotomisi ile 6 mm mandibula geri alındı; ikinci olguda bimaksiller ortognatik cerrahi (4 mm maksiller ilerletme ve 4 mm mandibular set-back) yapıldı. Sonuç: Ameliyat sonrası yapılan ortodontik tedavi ile dişler uygun pozisyonlarına getirilerek oklüzyon düzeltildi ve tedavi sonunda iskelet ve dişsel Sınıf I ilişkisi ile ideal bir yumuşak doku profili elde edildi.
