Alternative treatments of sinus augmentation with bone grafts: research status and clinical application

Abstract:

The traditional sinus lifting uses bone grafts to fulfill extended space in order to promote bone formation. However，it has disadvantages such as donor site deformity，immunologic rejection，high cost-effect etc. Therefore，with the improvements of tissue engineering and biomaterials，some bone substitute materials，eg. blood products and injectable hydrogel，were used in bone augmen－tation procedures. Besides，sinus lifting without any grafts was reported to be successful. Furthermore，in order to avoid the complications and complexity of sinus augmentation，some alternative strategies had been introduced to enable implantation without sinus lifting. There are still debates about the necessity and optimal choices of grafting materials and alternative treatment of sinus lifting proce－dures，so the aim of the study is to make a mini-review about the alternative therapy of sinus augmentation including the osteogenesis mechanism，influencing factors，grafting material selection and alternative surgery.
