PREFABRİKE METAL POST-KOR RESTORASYONLARIN KLİNİK BAŞARISININ DEĞERLENDİRİLMESİ: 5 YILLIK RESTROSPEKTİF ÇALIŞMA

Amaç: Bu retrospektif çalışmanın amacı, prefabrike metal post-kor restorasyonların 5 yıllık kullanım süresi içindeki başarı oranı ve başarısızlık tiplerini değerlendirmektir. Gereç ve Yöntem: Toplam 149 prefabrike metal post ile 5 yıl önce tedavi edilen 85 hastanın kayıtları incelendi ve geri çağrıldı. Yapılan klinik ve radyografik değerlendirmede: post retansiyon kaybı, kron retansiyonunun kaybı, kırık sonrası, kök kırığı, sekonder çürükler, apikal lezyonlar, protez restorasyon tipi (kron / köprü / hareketli bölümlü protez), lokasyonu (üst / alt çene, kesici / köpek / küçük azı / büyük azı dişi) parametreler incelendi. Alınan veriler ile başarı ve başarısızlık oranları hesaplandı. Bulgular: Post-core restorasyonların başarı oranı %91,94 bulundu. En sık görülen başarısızlık çeşidinin protetik restorasyonda restorasyon kaybı (%16.10) ve ardından sekonder çürüklerin (%9,39) olduğu tespit edildi. Postta tutuculuk kaybı başarısızlık oranı %3.35 bulundu. Hiçbir kök kırığı kaydedilmedi. Protetik restorasyon tipine göre başarısızlık oranları hareketli bölümlü protezlerde %23.08, kronda %8.64 ve köprü restorasyonlarında %3.64 bulundu. Sonuç: Sonuçlar post-kor restorasyonların başarı oranının tatmin edici sınırlarda olduğunu gösterdi. Ancak hareketli bölümlü protez vakalarında daha yüksek post tutuculuk kaybı oranı görüldüğünden, hareketli proteze destek dişin post-kor restorasyonlar ile tedavi edilmesine karar verilirken dikkat edilmelidir.

Material and methods: The records of 85 patients, who had been treated with 149 prefabricated metal posts were analysed and recalled after 5 years of treatment for clinical and radiological examination. The parameters that were used in the evaluation were: loss of post retention, loss of crown retention, post fracture, root fracture, secondary caries, apical lesions, type of prosthetic restoration (crown / bridgework / removable partial denture), location ( upper / lower jaw, incisor / canine / premolar / molar). The success and failure rates were calculated. Results: The success rate of post-core restorations was 91,94%. Loss of prosthetic restoration retention was the most frequent failure mode (16.10%), followed by secondary caries (9,39%). The failure rate of post retention loss was 3.35%. No root fractures were recorded. The failure rates according to the type of prosthetic restoration were 23.08% in removable partial dentures, 8.64% in crown and 3.64% in bridgework restorations. Conclusion: The results showed that the success rate of post-core restorations were in satisfactory limits. However, since the higher loss of post retention rate was seen in removable partial denture cases, it should be paid attention in deciding to treat the supporting tooth of removable denture with a post-core restoration. Keywords: Success rate, Post-core, Retention loss
