Alt çene ön bölge çapraþýklýða sahip olgularda iki farklý braket sisteminin kýsa dönem etkilerinin deðerlendirilmesi

GÝRÝÞ ve AMAÇ: In-Ovation (self-ligating) ve Synergy (low friction) braketlerin mandibula ön bölge çapraþýklýðýn tedavi edilmesinde birbirlerine göre etkinliklerinin ve üstünlüklerinin, hastanýn tedavi sürecinde hissettiði aðrýnýn, diþsel geniþlikler üzerine etkilerinin ve ark teli deðiþimi sýrasýnda geçen sürenin karþýlaþtýrýlarak deðerlendirilmesidir.
YÖNTEM ve GEREÇLER: Çalýþma, Ordu Üniversitesi Diþ Hekimliði Fakültesi Ortodonti Anabilim Dalý’na baþvurmuþ mandibula anterior çapraþýklýðý olan 32 hasta üzerinde yapýlmýþtýr. Hastalar rastgele 2 gruba ayrýlmýþtýr. Birinci gruptaki 16 hastanýn (yaþ ort. 16±1,41 yýl) tedavisi In-ovation, diðer gruptaki 16 hastanýn (yaþ ort. 15,45±2,02 yýl) tedavisi ise Synergy braketlerle yapýlmýþtýr. Tedavi baþýnda ve tedavi baþladýktan 16 hafta sonra bütün hastalardan alt çene dental alçý modeller elde edilmiþ ve modeller üzerinde interkanin, interpremolar, intermolar geniþlikler, kanin, premolar, molar derinlikler ölçülmüþ ve hayes-nance analizi yapýlmýþtýr. Hastalarýn seviyeleme sýrasýndaki hissettikleri aðrý Visual Analogue Scale (VAS) yardýmý ile ölçülmüþtür. Hasta baþýnda geçen süreyi deðerlendirmek için tel deðiþtirme süreleri karþýlaþtýrýlmýþtýr. Gruplar arasý karþýlaþtýrmada baðýmsýz t testi, grup içi tekrarlý karþýlaþtýrmalarda ise Friedman testi kullanýlmýþtýr.
BULGULAR: Her 2 braket interkanin, interpremolar, intermolar geniþlik ve kanin, premolar, molar derinlik ölçümleri, hayes-nance analizi, VAS deðerleri karþýlaþtýrýldýðýnda gruplar arasýnda bir farklýlýk bulunamamýþtýr. Synergy grupta ark teli deðiþimi sýrasýnda geçen sürenin Ýnovation ile tedavi edilen gruba göre istatistiksel olarak anlamlý þekilde daha fazla olduðu bulunmuþtur.
TARTIÞMA ve SONUÇ: Her iki braket sisteminin çapraþýklýðý çözme, dental geniþlik ve derinlik ölçümlerindeki deðiþimler ve hastanýn tedavi sürecinde hissettiði aðrý açýsýndan birbirlerine üstünlükleri bulunamamýþtýr. Bütün bu bilgiler ýþýðýnda, low friction (Synergy) braketlerin, self ligating (In-ovation) braketlere alternatif tedavi seçeneði olarak kullanýlabileceði söylenebilir

An assessment of short-term effects of two different bracket systems in mandibular anterior crowding

INTRODUCTION: In-ovation (self-ligating) and synergy (low friction) brackets are compared with each other’s effectiveness and advantages, the pain experienced during the treatment process by the patient, the effects on dental widths, the duration of the arch wire change in the treatment of mandibular anterior crowding.
METHODS: This study was performed on 32 patients with mandibular anterior crowding who were referred to the Orthodontics Department of Ordu University Dental Faculty. Patients randomly were divided into 2 groups. 16 patients were treated with In-ovation brackets (mean age 16±1.41 years) and 16 patients were treated with Synergy brackets (mean age 15.45±2.02 years). At the beginning of the treatment and 16 weeks after the treatment was started, dental cast models of the lower jaw were obtained from all patients and intercanine, interpremolar, intermolar widths, canine, premolars, molar depths were measured and hayes-nance analysis was made on the models. The pain experienced during the leveling was measured with the Visual Analogue Scale (VAS) by the patients. The duration of the arch wire change was compared for the evaluation of the chair time. Independent t test was used in the comparison between the groups, and Friedman test was used in the intra-group repeated comparison.
RESULTS: No difference was found between the groups when intercanine, interpremolar, intermolar width and canine, premolar, molar depth measurements, hayes-nance analysis, VAS values were compared. The duration of the arch wire change was found statistically significantly more in Synergy group than In-ovation group.
DISCUSSION AND CONCLUSION: There was no statistically difference in amount of resolution crowding, changes in dental width and depth measurements, and pain experience by the patient during the treatment process between the two brackets systems.
