Amaç: Bu çalışmanın amacı, farklı açılarda hazırlanmış implant abutmentlerine uygulanan çevresel oluk ve deliklerin implant destekli restorasyonların tutuculuğuna etkisinin araştırılmasıdır.
Gereç ve yöntemler: Toplam altmış adet standart implant dayanağı kullanıldı. Abutmentler CNC üzerinde 15° ve 30° açılarda olmak üzere iki gruba ayrıldı. Modifikasyona göre her grup 3 alt gruba ayrıldı; (1) kontrol, (2) çevresel oluklu ve (3) havalandırma delikli. Tüm abutmentler için lazer sinterleme kullanılarak altmış adet metal altyapı hazırlandı. Tüm metal altyapılar, öjenol içermeyen geçici siman ile simante edilmiştir. Daha sonra, tüm örneklere termal döngü işlemi yapıldı. Tüm örneklere universal test cihazında 5mm/dk başlık hızı ile vertikal çekme testi uygulandı. İstatistiksel analiz, iki yönlü ANOVA, post hoc Tukey (HSD) test ve bağımsız student t-testleri ile yapıldı.
Bulgular: Sonuçlara göre 15° ve 30° grupları arasında tutuculuk değerleri açısından anlamlı fark bulundu (p < 0.001). Ek delik ve oluklar, her iki grupta tutuculuğu arttırdı. Tutuculuk değerlerinin en yüksek ortalama değeri (185.00 ± 23.08 N) 15° oluklu grubunda, en düşük tutuculuk ortalama değeri (27.60 ± 14.84 N) 30° kontrolde gösterildi. Oluk ilave edilen grupların ortalama değerleri her iki grupta da en yüksek değerlere sahip bulundu. Tüm gruplarda, tüm alt gruplar arasında anlamlı farklılıklar bulundu (p < 0.05).
Sonuçlar: Artan abutment açısı tutuculuğu azaltırken, uygulanan delik ve oluk ilavesinin tutuculuğu arttırdığı görülmektedir.

The Effect of Different Angled Abutments with Peripheral Groove and Vent Hole on the Retention of Cement Retained Implant – Supported Restorations

Öz

Background: The purpose of this study was to analyze the effect of vent hole or peripheral groove on retention of differently angled (15 ° and 30 o) abutments in of cement retained implant supported restorations. Methods: A total of sixty standart implant abutments were used. Abutments were divided into two groups at 15 ° and 30 ° angles on CNC. According to the modification, each group were divided into 3 subgroups; (1) no modifications, (2) with peripheral groove and (3) with vent hole. Sixty metal frameworks were prepared using laser sintering to fit all abutments. All laser sintered frameworks were cemented with eugenol-free provisional cement. Then, all specimens were thermocycled. The frameworks were removed from the abutments by using the universal test machine and the peak removal force was recorded. Statistical analysis were performed with two-way ANOVA, post hoc Tukey’s (HSD) test-adjusted independent samples t-tests. Results: According to the results, there were significant differences between 15 ° and 30 ° groups in terms of retention values (p < 0.001). Additional hole and grooves enhanced retention in both groups. The highest mean value of vertical pull-out strength (185.00 ± 23.08 N) was showed in 15 ° additional grooves group, and the lowest mean value of vertical pull-out strength (27.60 ± 14.84 N) was showed in 30° control group. Means values of additional groove specimens had the highest scores in both groups. In all groups, there were significant differences between all subgroups (p < 0.05). Conclusion: Increased abutment angle decreases retention, while addition of hole and groove increases.
