Maxillary sinus floor augmentation: with or without bone grafting / 中国组织工程研究

ABSTRACT

BACKGROUND: Insufficient bone mass in the posterior maxilla region often increases the difficulty of dental implantation. The application of maxillary sinus floor elevation successfully solves this problem. In the surgery bone grafting can be used to obtain sufficient bone mass. However, nonuse of graft materials can shorten the cycle of patient's treatment and reduce trauma and cost. OBJECTIVE: Combining the latest relevant research trends, to review the advances in the study of maxillary sinus floor elevation with and without bone grafting. METHODS: The first author searched PubMed, VIP, WanFang and CNKI databases using computer for relevant articles published from January 1985 to August 2018. The key words were "dental implant, maxillary sinus, bone augmentation, bone substitute" in English and Chinese, respectively. Finally, 78 articles were included in result analysis after screening and summarizing. RESULTS AND CONCLUSION: Ideal results can be achieved in the maxillary sinus floor elevation with or without simultaneous bone grafting In addition, the nonuse of grafting materials have the advantages of simplifying surgical procedures, shortening treatment cycles, reducing trauma and pain, reducing treatment costs, reducing complications and failure rates, thus gaining the favor of doctors and patients. Therefore, the maxillary sinus floor elevation without simultaneous bone grafting will be the primary choice of the doctors engaged in dental implantation in the future.
