Abstract

Giriş: Enfeksiyon, aşırı ısınma, erken yükleme ve iyileşmenin bozulması dental implantların erken kayıpları ile ilişkili başlıca faktörlerdir. Aynı hastada birden çok implant kaybı bireysel özelliklerin erken başarısızlık sürecinde önemli bir rol oynadığı yönündeki delilleri kuvvetlendirmektedir. Veillonella dental biyofilmde erken kolonize olan türlerdendir ve küçük, sıklıkla fermentatif olmayan, zorunlu anaerob, hareketsiz, sporsuz, kapsülsüz gram-negatif koklardır. Amaç: Bu çalışmanın amacı bir hastada meydana gelen çoklu implant kayıpları ile olası faktörler arasındaki ilişkiyi araştırmaktır. Olgu Sunumu: 55 yaşında bayan hastanın alt çene sol posterior bölgesine yapılan implant operasyonlarından 3 ay sonra birbirine komşu 2 implant bölgesinde periimplant radyolusensi tespit edilmiştir. İmplant kaybı olan bölgelerde peri-implant mikroflora aerobik ve anaerobik kültür teknikleri ile çalışılmıştır. Amoksisiline dirençli Veilonella bakterisi izole edilmiştir. Sonuç: Bu vaka raporuna göre amoksisiline dirençli Veilonella türlerine bağlı olarak gelişebilen periimplantitisin erken implant kayıpları için bir risk faktörü olabileceği gösterilmiştir

Veillonella Spp. Infection As a Rare Cause for Early Multiple Dental Implant Failures: A Case Report

Abstract

Background: Infection, overheating, premature loading and impaired healing are the main factors associated with early failure of dental implants. Multiple implant failures in the same patient, supports the evidence that individual characteristics play an important role in the early failure process. Veillonella spp. are early colonizers of dental biofilms and small, usually non-fermentative, strict anaerobic, nonmotile, nonsporulating, gram-negative cocci that lack capsule.Objective: The objective of this study was to investigate the possible associated factors and early multiple implant failures in the same patient.Case Description: A 55-years-old female patient had peri-implant radiolucencies of two adjacent implant sites at the left posterior mandibula 3 months after surgical placement. Aerobic and anaerobic culture techniques were used to study the peri-implant microflora at sites with implant failures. An amoxicillin-resistant Veillonella bacteria was isolated. Conclusion: The present case shows that amoxicillin-resistant Veillonella associated peri-implantitis can be a risk factor for early implant failures
