Abstract
Objectives: The aim of this study is, toinvestigate the effects of crown length-implantlength ratios, implant diameters implant types andfollow-up periods of patients on the marginal boneloss in the implant-supported restorations.Materials and Methods: The lengths of dentalimplants were measured on the orthopantographsthat were taken after implantation and afterrestoration at the follow-up of 61 implant-supportedrestoration restorated in Erciyes University Facultyof Dentistry. The magnification ratio of radiographswas calculated with the measured lengths ofimplants and the real lengths of implants. Then,averages of mesial and distal marginal bone levelswere measured with reference to the implant neck.The differences between the marginal bone levels(magnification ratios were taken into account) thatwere measured from first and secondorthopantographs were noted. Finally, the effects ofcrown length-implant length ratio, implantdiameter, implant type and follow-up periods on themarginal bone loss were evaluated.Results: The effects of diameter of implant,type of implant and follow-up period of implantsupported restorations on the marginal bone losswere not statistically significant (p>0.05). Theimplants that have crown length-implant lengthratio above 1 showed more marginal bone loss thanthe implants that have crown length-implant lengthratio below 0.5. And this difference was statisticallysignificant (p=0.006). Marginal bone loss values ofall subgroups were within clinically acceptablelimits.Conclusion: As a result of this study, ratio ofcrown length-implant length, implant diameter,implant type and follow-up periods of implantsupported restoration cause bone loss withinacceptable limits.

Abstract
Amaç: Bu çalışmanın amacı, implant üstü kron
restorasyonlarında kron boyu-implant boyu
oranlarının, implant çaplarının, implant tiplerinin ve
implant kullanım sürelerinin marjinal kemik kaybı
üzerine etkilerinin incelenmesidir.
Gereç ve Yöntem: Erciyes Üniversitesi Diş
Hekimliği Fakültesi’nde yapılan 61 implant üstü
kron restorasyonundan, implantlar yerleştirildikten
hemen sonra ve restorasyonlar tamamlandıktan
sonra kontrol randevularında alınan iki panoramik
röntgen üzerinde, resim düzenleme yazılımı
kullanılarak dental implantların boyu ölçüldü.
Radyograflar üzerinde tespit edilen implant boyu,
implantın gerçek boyuna oranlanarak panoramik
radyografın magnifikasyon miktarı hesaplandı.
Daha sonra, implantın boynu referans alınarak
mezial ve distal noktalardan ölçülen marjinal kemik
seviyelerinin ortalamaları alındı. Her iki panoramik
radyograftan elde edilen marjinal kemik seviyeleri
arası fark (magnifikasyon oranı da hesap edilerek)
not edildi. Sonuç olarak, kron boyu-implant boyu
oranı, implant çapı, implant tipi ve implant
kullanım sürelerinin marjinal kemik kaybına etkisi
değerlendirildi.
Bulgular: İmplant çapının, implant tipinin ve
takip süresinin marjinal kemik kaybına etkisi
istatistiksel olarak anlamlı bulunmamıştır (p > 0,05).
Kron boyu-implant boyu oranı 0,5’in altında olan
grupla 1’in üzerinde olan grup arasında marjinal
kemik kaybı bakımından anlamlı farklılık
bulunmuştur (p=0,006). Tüm alt gruplar için elde
edilen kemik kaybı değerleri klinik olarak kabul
edilebilir sınırlar içerisindedir.
Sonuç: Çalışmamızın sonucunda, kron boyuimplant
boyu, implant çapı, implant tipi ve takip
süresinin implant üstü kron restorasyonlarının
marjinal kemik seviyesinde kabul edilebilir
sınırlarda kemik kaybına sebep olduğu sonucuna
ulaşılmıştır
