Maksiller darlığı ve şiddetli çapraşıklığı olan hastanın cerrahi destekli üst çene genişletme tedavisi (SARME) : Olgu sunumu

The aim of this case report is to present an adult patient with a narrow maxilla and severe crowding treated with the help of surgically assisted maxillary expansion. A 17-year-old male patient referred to our clinic for the primary complaint of unaesthetic smile and severe upper anterior crowding. Extraoral examination revealed convex profile. Intraoral examination revealed narrow maxilla, posterior cross bite, V shaped upper arch form and severe crowding. The treatment was initiated with corticotomy operation for maxillary expansion. A tooth-borne acyrilic cap splint appliance with Hyrax screw was then fixed for distraction. Distraction protocol was started 7 days postoperatively by 2 turns a day (0.5 mm/ day). The distractor was left in place for an additional 3 months for stabilization and reossification after the required space had been achieved. Orthodontic fixed treatment started within 4 weeks after removal of the appliance. Computed tomography scans of the patient were performed to help the planning of the treatment 1 month before the orthodontic treatment. The data reconstructed using the Mimics software (Materialise, Leuven, Belgium) for surgical planning. Surgically assisted maxillary expansion is a successful treatment modality for adult patients requiring palatal expansion. The total treatment period was 24 months and the results were acceptable.Bu olgu sunumunun amacı dar üst çeneye ve şiddetli yer darlığına sahip yetişkinhastanın cerrahi destekli üst çene genişletilmesi yardımı ile tedavisinin sunulmasıdır.17 yaşında erkek hasta estetik olmayan gülümseme ve şiddetli üst ön çapraşıklık ilekliniğimize başvurdu. Ağız dışı incelemede konvex bir profil olduğu gözlendi. Ağıziçi incelemede dar bir maksilla, arka bölgede çapraz kapanış, V şekilli üst ark formuve şiddetli çapraşıklık gözlendi. Tedavi cerrahi operasyon ile başladı. Hyrax vidaiçeren diş destekli akrilik cap splint distraksiyon apareyi uygulandı. Distraksiyonprotokolüne operasyon sonrası 7 günlük bekleme sonrası günde 2 tur (0.5mm/gün) olacak şekilde başlandı. Gerekli yer elde edildikten sonra stabilizasyon ve yenikemik oluşumunun beklenmesi amacıyla distraktör operasyon sonrası 3 ay ağızdabırakıldı. Apareyin çıkartılmasını takiben 4 hafta sonra sabit tedaviye başlandı.Tedavi planlaması amacıyla hastanın bilgisayarlı tomografi görüntüleri tedaviden 1ay önce alındı. Analiz amaçlı, veriler Mimics (Materialise, Leuven, Belgium) yazılımıile yeniden oluşturuldu. Cerrahi destekli üst çene genişletme tedavisi palatalekspansiyon ihtiyacı olan yetişkin hastalarda başarılı bir tedavi yöntemidir. Toplamtedavi 24 ay sürmüştür ve kabul edilebilir sonuçlar elde edilmiştir

Evaluation of the Relationship between Curve of Spee, WALA-FA Distance and Curve of Wilson in Normal Occlusion

Objective: To test the hypotheses that (i) there is a significant correlation between the curve of Spee (COS), basal arch (WALA ridge) to dental arch distance (WALA-FA distance) and curve of Wilson (CW) and that (ii) the deepening of the COS is affected by the CW and the WALA-FA distance. Methods: Mandibular models of 50 patients aged between 20 and 35 years were scanned with TRIOS. the xyz coordinate system was determined, and a reference occlusal plane was generated. the depth of the COS, the CW, and WALA-FA distance were measured using an engineering software. Results: the greatest difference in the measurement of the depth of the COS between the right and left was found to be 0.41±0.50 mm in the first molar teeth. on the basis of the results of Pearson correlation analysis, there was no strong correlation between the depth of the COS, the CW, and the WALA-FA distance. Conclusion: It was shown that there was no strong correlation between the depth of COS, CW, and WALA-FA distance. the CW and WALA-FA distance could not be effective in the deepening of the CO
