Assessment of implant stability in sinus lifting procedures

Öztürk, S., Assessment of implant stability in sinus lifting procedures. Yeditepe University Health Sciences Institute MSc Thesis in Oral Surgery, Istanbul, 2008. Bone height between alveolar crest and maxillary sinus becomes inadequate for implant placement because of bone resorption due to aging and maxillary sinus pneumatization. Augmentation of maxillary sinus floor and implant placement can be performed both one stage and two stages. Autogenous bone grafts are the first preferred choice in sinus lifting for their high osteogenic activity, but necessity of second surgical procedure and donor site morbidity enabled allografts and alloplastic grafts to become more popular. Implant stability is one of the important factors in the long-term succes; however, there is not a spesific method to analyze stability and osseointegration. Today, resonance frequency analysis is commonly used to assess implant-bone surface integration. In this rewiev, factors effecting implant stability in sinus lifting procedures are discussed by the current literature
