ABSTRACT
 Objective: We aimed to retrospectively evaluate the volume of new bone formed following sinus floor augmentation with simultaneous dental implant placement in severely atrophied residual alveolar ridges using a combination of platelet-rich fibrin and demineralized cortico-cancellous bone allograft in a geriatric population. Material and Methods: The clinical and radiological data of patients who underwent sinus floor augmentation using a combination of platelet-rich fibrin and demineralized cortico-cancellous bone allograft with simultaneous dental implant placement between 01 April 2013 and 01 August 2020 were retrieved from the archives. The main inclusion criteria for the study were age >60 years and a residual ridge height <2 mm. For each patient, cone-beam computed tomography (CBCT) scans were performed preoperatively, and 6 months after surgery. The volume of the maxillary sinus cavity preoperatively and postoperatively was measured using CBCT. The volume of the newly regenerated bone was calculated by subtracting the post-operative total sinus volume from the pre-operative total sinus volume. Residual and postoperative ridge heights were measured on the mid-coronal and mid-sagittal sections of preoperative and postoperative cone beam computed tomography images, respectively. Results: Fourteen patients with 19 sinus augmentations were included in the study. Thirty-two dental implants were placed with simultaneous sinus floor augmentation. All cases showed new bone formation on axial, coronal, and sagittal sections of postoperative CBCT scans. Conclusion: The combination of plateletrich fibrin and demineralized cortico-cancellous bone allograft used in sinus flor augmentation may promote the formation of healthy new bone that supports the simultaneous placement of dental implants in the elderly population with severely atrophic alveolar ridges.

ÖZET
 Amaç: Bu çalışmada, geriatrik popülasyonda trombositten zengin fibrin ve demineralize kortikokansellöz kemik allogreftinin bir kombinasyonunu kullanarak ciddi derecede atrofik rezidüel alveolar kretlere eş zamanlı dental implant yerleştirme ile sinüs tabanı ögmentasyonunu takiben oluşan yeni kemik hacmini retrospektif olarak değerlendirmeyi amaçladık. Gereç ve Yöntemler: 01 Nisan 2013-01 Ağustos 2020 tarihleri arasında trombositten zengin fibrin ve demineralize kortikokansellöz kemik allogrefti ile sinüs ögmentasyonu ve eş zamanlı dental implant uygulaması yapılan hastaların klinik ve radyolojik verileri arşivlerden alınmıştır. Çalışmaya dâhil etme kriterleri 60 yaşından büyük hastalar ve 2 mm'den küçük rezidüel kemik yüksekliğidir. Her hasta için ameliyat öncesi ve ameliyattan 6 ay sonra konik ışınlı bilgisayarlı tomografi (KIBT) taraması yapıldı. Preoperatif ve postoperatif maksiller sinüs boşluğunun hacmi, KIBT kullanılarak ölçüldü. Yeni oluşan kemiğin hacmi, ameliyat öncesi toplam sinüs hacminden ameliyat sonrası toplam sinüs hacminin çıkarılmasıyla hesaplandı. Rezidüel ve postoperatif kret yükseklikleri preoperatif ve postoperatif KIBT görüntülerinin koronal ve sagittal kesitlerinde ölçüldü. Bulgular: Çalışmaya 19 sinüs ögmentasyonu olan 14 hasta dâhil edildi. Eş zamanlı sinüs tabanı ögmentasyonu ile 32 dental implant yerleştirildi. Tüm olgularda postoperatif KIBT görüntülerinin aksiyal, koronal ve sagittal kesitlerinde yeni kemik oluşumu görüldü. Sonuç: Sinüs tabanı ögmentasyonunda kullanılan trombositten zengin fibrin ve demineralize kortikokansellöz kemik allogreftinin kombinasyonu, ileri derecede atrofik alveolar kretleri olan geriatrik popülasyonda dental implantların aynı anda yerleştirilmesine olanak sağlayarak sağlıklı yeni kemik oluşumunu teşvik edebilir.
