KISA İMPLANTLARIN 19 AYLIK GERİYE DÖNÜK KLİNİK BAŞARILARININ DEĞERLENDİRİLMESİ

Amaç: Bu çalışmanın amacı 10 mm’nin altında kemik yüksekliğine sahip bölgelerde yerleştirilen kısa implantların ortalama 19 aylık takip süresinde, implant klinik başarısının araştırılması ve marjinal kemik kaybının, implantın; lokasyonuna, kron/ implant oranına ve hastanın; cinsiyeti, yaşı ve sigara kullanımı gibi parametrelere göre değerlendirilmesidir. Gereç ve Yöntem: Bu çalışmada; yaşları 20-82 arasında değişen 64 hastaya toplamda 101 adet implant yerleştirildi. İmplantlar 10 hafta iyileşme sürecini takiben yüklendiler. Marjinal kemik kayıpları başlangıç ve ortalama 19 ay sonrasında ölçüldü. Hastaların implant çevre kemik doku kaybı; implant ve hastaya bağlı parametrelere göre değerlendirildi. Ayrıca klinik takip süresi sonundaki yaşam ömürleri hesaplandı. Bulgular: Çalışmamızda 19 aylık takip süresinde implantlarda ki başarı oranı %98 dir. İmplantların takip süresi içerisindeki ortalama marjinal kemik kaybı 0,33 ± 0,19 mm olarak bulundu. Kısa implantlarda kron/implant oranının marjinal kemik kaybına etkisi istatistiksel olarak anlamlı bulundu. Ayrıca hastanın yaşı ve sigara kullanımın da marjinal kemik kaybına etkisi istatiksel olarak anlamlı bulundu. Buna karşın hastanın cinsiyetinin marjinal kemik kaybına etkisi istatiksel olarak anlamlı tespit edilmedi. Sonuç: Bu kısa dönem takip çalışması standart uzun dental implantların uygulanamadığı vakalarda kısa dental implantlantların kullanımının ortalama 19 aylık dönemde başarılı olduğunu tespit etmiştir. Ancak daha kesin verilere ulaşabilmek için uzun dönem takip çalışmaları gerekmektedir. Anahtar Kelimeler: dental implant, panoramik radyografi, başarı. THE SUCCESS RATES OF SHORT IMPLANTS IN A 19 MONTHS RETROSPECTIVE EVALUATİON ABSTRACT Aim: The aim of this study is the evaluation of the success rate of short implants in patients who have less than 10 mm alveolar bone in posterior regions of maxilla and mandible in average 19 months follow-up time. And evaluation of the marginal bone loss around implants according to patient related parameters as smoking, age, gender and implant related parameters as location and crown/implant ratio. Materials and Methods: One hundred and one implants were placed in 64 patients and loaded with final restorations after 10 weeks of healing time. Marginal bone loss around implants was determined radiographically at initial and after a mean observation time average of 19 months. The effect of smoking habit, age, gender, implant location and crown/implant ratio on the marginal bone loss was evaluated. The survival rate of the implants was determined. Results: The overall cumulative survival rate of short implants in 19 months was 98%. The mean marginal bone loss value for the short implants was 0,33 ± 0,19 mm. Marginal bone loss was affected by the crown/implant ratio, location, patients’ smoking habit and age but not the gender of the patient. Conclusion: With short dental implants, successful clinical results could be achieved in patients who have less than 10 mm alveolar bone in posterior regions of maxilla and mandible up to 19 months of short follow-up time. Long term studies are needed for short dental implants. Key words: dental implant, panoramic radiograph, success.
