Imaging Evaluation and Clinical Controlled Study of Bone Augmentation with CGF in Lateral Maxillary Sinus Floor Augmentation

doi:10.13701/j.cnki.kqyxyj.2021.02.016

Abstract

Abstract: Objective: To explore the clinical efficacy of CGF combined with bone substitute material in maxillary sinus augmentation and the imaging changes by Mimics software. Methods: The patients were divided into two groups: experimental group (10 cases, CGF combined with bone substitute group) and control group (10 cases, only using bone substitute group). After introducing the CBCT data of the day and 6 months after lateral sinus lift into Mimics 19.0 software, the short-term bone resorption rate and the increased multiple of bone mineral density were calculated. Complications, postoperative satisfaction (VAS), and survival rate were evaluated. Results: During the follow-up period, all 20 patients achieved positive results. Imaging examination: the average bone resorption rate of the experimental group was significantly higher than that of the control group (P<0.05). The average bone mineral density of the experimental group was significantly higher than that of the control group (P<0.05). Conclusion: The combination of CGF and bone substitutes can achieve good clinical effect in the treatment of severe bone deficiency in the posterior maxillary region, and the addition of CGF can increase the density of bone tissue in maxillary sinus, but its long-term effect needs further follow-up.
