Mandibula Kırıklarında Tel, Polydioxanone ve Mini Plak Osteosentez Materyallerinin Kırık Kaynamasına Etkilerinin Karşılaştırmalı Olarak Araştırılması: Tavşanlarda Deneysel Çalışma
Bu çal›flmada 30 adet tavflan›n mandibulas›nda deneysel olarak oluflturulan corpus mandibula k›r›klar›n›n 3 farkl› materyal ile fikzasyonlar› yap›ld›. Onarl› 3 farkl› gruba ayr›lan olgulara s›ras›yla tel, polydioxanone ve mini titanyum plak ve vida osteosentez materyalleri uyguland› ve k›r›k kaynamas›na klinik, radyolojik ve histopatolojik olarak nas›l etkilediklerinin karfl›laflt›rmal› olarak araflt›r›lmas› yap›ld›. Radyolojik olarak kallus dokusu, mineralizasyon ve remodeling parametreleri aç›s›ndan gruplar karfl›laflt›r›ld› ve Lane-Sandhu de¤erlendirme sistemi uyguland›. Histopatolojik olarak ise, histolojik kaynama ve kallus dokusu aç›s›ndan gruplar karfl›laflt›r›ld› ve Modifiye Heiple de¤erlendirme sistemi uyguland›. Radyolojik ve histopatolojik de¤erlendirme sonucunda en iyi puanlamay› ve anlaml› sonuçlar› mini titanyum plak osteosentez materyali uygulanan 3. gruptan elde edildi. Sonuç olarak mandibula k›r›klar›n›n sa¤alt›m›nda mini titanium plak ve vida sisteminin güvenle tercih edilebilece¤i istatistiksel olarak da belirlenirken, tel dikifl kullan›lmas›n› gerektiren durumlarda ise, bunun yerine polidioxanone materyalinin güvenle kullan›labilece¤i kan›lar›na var›ld›.
Comparative Study on the Effects of Wire, Polydioxanone, and Mini Titanium Plate Osteosynthesis Materials on the Healing of Mandibular Fractures: An Experimental Study in Rabbits
In this study, corpus mandibula fractures were experimentally induced on 30 rabbits and 3 different materials were used for fixation. Thirty rabbits were arranged into 3 groups and then wire, polydioxanone and mini plate and screw osteosynthesis materials were used. The fracture healing was examined and compared with clinical, radiological and histological results. From the radiological results the parameters of groups were compared with Lane and Sandhu scale system in terms of callus tissue, mineralization and remodeling. The histological results were evaluated according to the Modified Heiple scoring and compared for histological fracture healing and callus tissue. At the end of the radiological and histological evaluation the 3rd group had the most logical data with mini titanium plate and screws system. In conclusion, with statistical data in mandibular fracture mini titanium plates and screws are found to be the safest way. In addition, the polydioxanone suture material was considered for use instead of wire suture material if necessary.
