Özet

Bu çalışmanın amacı implant üstü overdenture protezlerde kullanılan Ball ve Locator ataşmanların marjinal kemik kaybı üzerine etkisini araştırmaktır. Çalışmaya Ball veya Locator ataşmanlı iki implant destekli overdenturelar dahil edildi. İki grupta (n=12) toplam 24 implantın dokuz yıllık takip röntgenleri incelendi. Yükleme sonrası ve dokuz yıllık takip röntgenleri arasındaki kemik kayıpları bir görüntü işleme programı aracılığıyla hesaplandı. Gruplar arasında fark Mann-Whitney U testi ile incelendi, istatiksel olarak anlamlı fark bulunmadı (p=0,226). Marjinal kemik kayıplarının grup içi değerlendirmesinde yükleme ve takip zamanı arasındaki farklara Wilcoxon Signed Ranks testi ile bakıldı ve İstatiksel olarak anlamlı bir fark bulunmadı (Ball p=0,182; Locator p=0,327). Bununla birlikte Ball ataşman kullanılan implantlardaki marjinal kemik kaybı ortalamasının (0,237±0,831) Locator ortalamasından (0,093±0,558) fazla olduğu görüldü.

Abstract

The aim of this study is to investigate the effect of Ball and Locator attachments used in implant supported overdenture prostheses on marginal bone loss. Two implant supported overdentures with Ball or Locator attachments were included in the study. Nine-year follow-up x-rays of a total of 24 implants in two groups (n=12) were analyzed. Bone losses between post-loading and nine-year follow-up x-rays were calculated using an image processing program. The difference between the groups was evaluated with the Mann-Whitney U test, no statistically significant difference was found (p=0.226). In the within-group evaluation of marginal bone loss, the differences between loading and follow-up time were evaluated with the Wilcoxon Signed Ranks test and no statistically significant difference was found (Ball p=0.182; Locator p=0.327). However, the mean marginal bone loss in the implants with Ball attachment (0.237±0.831) was higher than the implants with Locator attachment (0.093±0.558).
