Abstract:

BACKGROUND: In recent years, the feasibility and the methods of applying bone substitute materials in maxillary sinus augmentation are in dispute, the developing instruments and imaging greatly facilitate the clinical application of maxillary sinus augmentation and modify surgical procedures, new surgical procedures have been reported to promote the maturation and development of maxillary sinus augmentation.
OBJECTIVE: To summarize the research progress of materials research, clinical applications of maxillofacial cone CT and ultrasound bone knife in maxillary sinus augmentation.
METHODS: PubMed database, SCI database, VIP database and Wanfang database from 2000 to 2010 were retrieved by the first author for articles about the maxillary sinus bone graft material, imaging and device applications, improved surgical procedures and other aspects.
RESULTS AND CONCLUSION: The development of materials science, imaging science and instrument in maxillary sinus augmentation can provide scientific service for preoperative diagnosis and measurement, operation design, prognosis design of oral implant. Current deficiencies and unsolved issues are addressed as: the selection and application of bone graft material in maxillary sinus augmentation, more effective and powerful comparisons are not available due to shorter observations of the bone graft; abandonment of bone graft material requires more research and experimental verification; maxillofacial cone CT is only the three-dimensional imaging of hard tissue, it cannot observe the conditions and measurement information of mucosa and other soft tissues, needing further research and development; ultrasonic bone knife emerges recently, the selection and operating skills of instrument working head require further exploration and clinical improvement.
