Anterior İskeletsel Açık Kapanışa Sahip Modellerde Ortognatik Model Cerrahisinde İki Farklı Yöntemin Etkinliklerinin Karşılaştırılması

Amaç: Bu çalışmanın amacı, ortognatik model cerrahisinde piezoelektrik ve geleneksel yöntemin etkinliğinin karrşılaştırılmasıdır. Gereç ve Yöntemler: Bu çalışmada fantom modeller üzerinde elde edilen alçı modeller kullanılmıştır. Maksiller subapikal osteotomi planlaması yapılan anterior iskeletsel açık kapanış modelleri oluşturulmuş ve 50 maksilla modeli çalışmaya dahil edilmiştir. 25 alçı model piezoelektrik cihazı ile 25 model ise piyasemen cihazı ile subapikal maksiller osteotomi cerrahisi için model cerrahisine hazırlandı. İstatistiksel anlamlılık p<0,05 olarak kabul edildi. Bulgular: Çalışma 2021-2022 tarihleri arasında Van Yüzüncü Yıl Üniversitesi Diş Hekimliği Fakültesi’nde %50’si (n=25) piezo cerrahi, %50’si (n=25) piyasemen yöntemi uygulanan toplam 50 alçı model üzerinde yapılmıştır. Yöntemlere göre alçı üzerinde model kırılması görülme oranları arasında istatistiksel olarak anlamlı farklılık saptanmadı (p>0,05). Piezo cerrahisi uygulanan alçı modelin osteotomi süresi, piyasemen uygulanan alçı modele göre istatistiksel olarak anlamlı düzeyde yüksek saptanmıştır (p=0,001; p<0,01). Piezo cerrahisi uygulanan alçı modelde model kırığına göre osteotomi süreleri arasında istatistiksel olarak anlamlı farklılık saptanmadı (p>0,05). Piyasemen uygulanan alçı modelde model kırığına göre osteotomi süreleri arasında istatistiksel olarak anlamlı farklılık görülmedi (p>0,05). Sonuç: Bu çalışmada cerrahi piyasemen yönteminin işlem süresi açısından piezo cerrahi yönteminden daha hızlı olduğu görüldü.

Comparison of the Efficiency of Two Different Methods in Orthognathic Model Surgery in Models with Anterior Skeletal Open Bite

Abstract Objective: This study compares the success of the piezoelectric and conventional methodsin orthognathic model surgery. Material and Method: In this study, plaster models obtained on phantom models were used. Anterior skeletal open bite models for maxillary subapical osteotomy planning were created and 50 maxilla models were included in the study. Twenty-five plaster models were prepared for model surgery with a piezoelectric device, and 25 models were prepared for subapical maxillary osteotomy surgery with a handpiece device. Statistical significance was accepted as (p<0.05). Results: The study was carried out on a total of 50 plaster models, 50% (n=25) of which were applied piezo surgery and 50% (n=25) of the handpiece method, at Van Yüzüncü Yıl University Faculty of Dentistry in 2022. According to the methods, no statistically significant difference was found between the incidence of model breakage on plaster (p>0.05). The osteotomy time of the plaster model in which piezosurgery was applied was statistically significantly higher than the plaster model with the handpiece applied (p=0.001; p<0.01). There was no statistically significant difference between osteotomy times in the plaster model with piezosurgery and the model fracture (p>0.05). According to the model fracture, there was no statistically significant difference between osteotomy times in the plaster model applied handpiece (p>0.05). Conclusion: In this study, it was observed that the surgical handpiece method was faster than the piezo surgical method in terms of the procedure time.
