Objective: Bone deficiency and other anatomical limitations might compromise dental implant surgery. Short implants are the easiest way to overcome this issue. The purpose of this study was to investigate survival rates of short dental implants versus long implants. Material and Methods: The study population included 137 patients treated with removable or fixed dentures supported by 548 dental implants. Data were analyzed to obtain survival rates in terms of age, gender, tobacco use, bony architecture, and prosthetic treatment style. Statistical analyses were carried out using Mann-Whitney U, Kruskal Wallis H, and chi-square tests. Results: The cumulative survival rate of short implants was 97.6% with 25.18 months of follow up. Elderly patients (>60 years old) had a lower implant survival rate than younger patients (p<0.05). Implant survival rates in short and long implants were affected by bone quality and gender (p<0.05). However, no other variables affected implant survival rates (p>0.05). In addition, there were no significant differences in implant survival rates between short (6 mm) and long (11 mm) dental implants after 25.18 months (p>0.05). Conclusions: Although there are some limitations of the present study, the conclusion can be made that short implants have similar survival rates compared to long implants. However, further studies with longer follow-up periods should be conducted.

Amaç: Kemik eksikliği ve diğer anatomik sınırlamalar, dental implant cerrahisini tehlikeye atabilir. Kısa implantlar, bu sorunun üstesinden gelmenin en kolay yoludur. Bu retrospektif çalışmanın amacı, kısa implantların uzun implantlara karşı sağkalım oranlarını karşılaştırmaktır. Gereç ve Yöntemler: Çalışma popülasyonu, 548 diş implantı ile desteklenen sabit veya çıkarılabilir protezlerle tedavi edilen 137 hasta idi. Veriler cinsiyet, yaş, sigara kullanımı, cerrahi işlem, kemik kalitesi ve protez restorasyon tipine göre sağkalım oranları elde etmek için değerlendirildi. İstatistiksel analizler ki-kare, Mann-Whitney U ve Kruskal-Wallis H-testleri kullanılarak yapıldı. Bulgular: Kısa implantların sağkalım oranı 25,18 aylık takip süresiyle %97,6 idi. Yaşlı hastalar (60 yaş üstü hastalar) diğer yaş gruplarından daha düşük bir sağkalım oranına sahipti (p<0,05). İmplant sağkalım oranları kısa ve uzun implantlarda kemik kalitesi ve cinsiyetten etkilendi (p<0,05). Diğer hiçbir değişken implant sağkalım oranını etkilemedi (p>0,05). Yaklaşık 25,18 aylık takip sonrasında kısa (6 mm) ve uzun (11 mm) diş implantları arasında implant sağkalımında anlamlı bir fark yoktu (p>0,05). Sonuçlar: Bu çalışmaya göre kısa implantların uzun implantlara kıyasla benzer sağkalım oranlarına sahip olduğu sonucuna varılabilir. Bununla birlikte, daha uzun takip süreleriyle daha ileri çalışmalar yapılmalıdır.
