Background: Early peri-implant crestal bone loss during the healing period and the first year on function, is often greater than the bone loss occurring in the following years. Several factors affecting marginal bone loss have been described; such as surgical trauma, flapped or flapless procedures, occlusal overload, microgap and implant crest module. The aim of this study; was to compare the amount of first year peri-implant bone loss in implants closed with cover screw or healing cap. Material and Methods: Patients with same brand, posterior single tooth implants included in this prospective study and divided into two groups. In group I, after implant placement healing cap was placed while in group II, cover screw was placed before primary closure. Panoramic radiographs, taken before and after the implant surgery and after 1 year follow up, were used in bone loss evaluations. Peri-implant bone loss measurements were performed digitally in computer assisted software programme. Results: Thirty implants included in the study with fourteen implants in group I and sixteen implants in group II. There were no perioperative or postoperative complications and no implant failure in all patients. After the first year, mean marginal bone loss was 0.7014 mm (0.2477 mm standard deviation) in group I and 1.3156 mm (0.0943 mm standard deviation) in group II. This 0.6142 mm difference was found statistically significant. Conclusion: Placing healing cap instead of cover screws may prevent periosteal tissue pressure on the crestal bone and reduce the amount of marginal peri-implant bone in the first year.

Amaç: İmplant tipinden bağımsız olarak iyileşme periyodu ve fonksiyondaki ilk yılda görülen erken dönem implant çevresi krestal kemik kaybı genellikle ilerleyen yıllarda oluşan kemik kaybından daha fazladır. Günümüze kadar, marjinal kemik kaybını etkileyen birçok faktör tanımlanmıştır. Bunlar; cerrahi travma, flapsiz ya da flap kaldırılan prosedürler, mikrogap, krestal implant modülü olarak sıralanmaktadır. Bu çalışmanın amacı; yerleştirme sonrası kapama vidası ile primer kapatılan implantlar ile iyileşme başlığı ile kapatılan implantların ilk yılda görülen implant çevresi kemik kaybına etkisini karşılaştırmaktır. Gereç ve Yöntemler: Bu prospektif çalışmaya 30 hasta dahil edilmiştir. Kemik seviyesi, “platform switch” özellikli, aynı marka, konik, posterior tek diş implantlar yerleştirilmiş hastalar iki gruba ayrılmıştır. Birinci grup, implant yerleştirilmesini takiben iyileşme başlığı takılan implantlardan oluşurken ikinci grupta implantlar kapama vidası ile primer olarak kapatılmıştır. Cerrahi öncesi, hemen sonrası ve 1 yıllık takip sonrası alınan panoramik radyograflar kemik kaybı değerlendirilmesinde kullanılmıştır. İmplant çevresi kemik kaybı miktarları, dijital olarak bilgisayar yazılımı aracılığıyla ölçülmüştür. Bulgular: Çalışmaya, iyileşme başlığı grubunda 14 adet ve kapama vidası grubunda 16 adet, toplamda 30 implant dahil edilmiştir. Perioperatif ve postoperatif dönemde herhangi bir komplikasyon görülmemiştir. Çalışma sonunda hiçbir implant başarısızlığı görülmemiştir. Birinci yıl sonrası iyileşme başlığı grubunda ortalama 0,7014 mm (0.2477 mm standart sapma) marjinal kemik kaybı görülürken, kapama vidası yerleştirilen ikinci grup implantlarda ortalama 1,3156 mm (0.0943 mm standart sapma) kemik kaybı ölçülmüştür. İki grup arasındaki 0,6142 mm’lik fark istatistiksel olarak anlamlı bulunmuştur. Sonuç: Yerleştirme sonrası kapama vidası yerine iyileşme başlığı yerleştirmek, krestal kemik üzerinde periost basıncını önleyerek özellikle ilk yılda görülen marjinal kemik kaybını önleyebilir.
