Cerrahi Destekli Hızlı Üst Çene Genişletmesi Sonrası Alveolar Kemik Kaybının ve Bukkal Kemik Kalınlığının Değerlendirilmesi

Amaç: Bu retrospektif çalışmanın amacı, cerrahi destekli hızlı üst çene genişletmesi (CDHÜG) sonrasında maksiller dişlerin alveolar kemik yüksekliğindeki ve bukkal kemik kalınlığındaki (BKK) değişiklikleri konik ışınlı bilgisayarlı tomografi (KIBT) kullanarak değerlendirmektir. Gereç ve Yöntemler: Operasyon öncesi ve operasyon sonrası KIBT kayıtları olan toplam 9 hasta çalışmaya dahil edildi. Bütün hastalara CDHÜG yapıldı ve tamamına üst çene genişletici olarak modifiye akrilik bonded apareyi uygulandı. KIBT görüntüleri, CDHÜG öncesi (T1) ve 3-4 aylık bir konsolidasyon süreci sonrası (T2) alındı. Alveolar kemik yüksekliği, KIBT görüntülerinde mine-sement hududu ile alveolar kret tepesi arasındaki mesafenin ölçülmesiyle tespit edildi. BKK’yi değerlendirmek için kök yüzeyi boyunca iki farklı nokta tespit edildi. Bulgular: T1 ve T2 alveolar kemik yüksekliği ölçümleri arasındaki farkla tespit edilen alveolar kemik kaybı (AKK) tüm dişlerin tüm yüzeylerinde istatistiksel olarak anlamlıydı. T1 ve T2 ölçümleri arasında her dişin her yüzeyinde BKK’de istatistiksel bir azalma vardı. Sonuç: Modifiye akrilik bonded apareylerle yapılan CDHÜG, diş kaybı ve dişeti çekilmesi riskini artıran AKK’ye ve BKK’de bir azalmaya neden olur.

Assessment of Alveolar Bone Loss and Buccal Bone Thickness After Surgically Assisted Rapid Maxillary Expansion

Objective: The aim of this retrospective study was to evaluate the changes in alveolar bone height (ABH) and buccal bone thickness (BBT) of the maxillary teeth after surgically assisted rapid maxillary expansion (SARME) using cone-beam computed tomography (CBCT). Materials and Methods: A total of 9 patients with preoperative and postoperative CBCT records were included in this study. All patients underwent SARME and all of them received a modified acrylic bonded appliance as a maxillary expander. CBCT images were taken before SARME (T1) and after a consolidation period of 3 to 4 months (T2). ABH was determined by measuring the distance from the cemento-enamel junction to the alveolar crest on CBCT images. To evaluate BBT, two different points were identified along the root surface. Results: Alveolar bone loss (ABL) detected between T1 and T2 ABH measurements was statistically significant at all sites of each tooth. There was a statistically significant decrease in BBT at all measured points of each tooth between the T1 and T2 measurements. Conclusion: SARME with modified acrylic-bonded appliances causes ABL and a decrease in BBT, which increases the risk of tooth loss and gingival recession.
