HA与β-TCP植骨效果及上颌窦提升种植修复临床效果观察

Effect of HA and β-TCP bone graft and clinical effect of maxillary sinus lifting implant repair

目的分析羟基磷灰石(HA)与β-磷酸三钙(β-TCP)植骨材料的成骨效果及上颌窦提升种植修复功能负载后的临床效果。方法选取2019年3月至2022年3月在承德医学院附属医院口腔科行上颌窦提升植骨同期种植体植入术的患者20例为研究对象,均植入HA与β-TCP骨材料,观察患者术后种植体存留率及相关并发症发生情况,观察术后1、6个月种植体周围骨量。结果20例患者(23枚种植体),种植体植入6个月后影像学检查显示种植体与牙槽骨之间骨结合良好,随访复查种植体存留率100%;HA+β-TCP患者上颌窦底提升植骨术后6个月颊舍、近远中向上颌窦黏膜底高度明显低于术后1个月(P<0.05)。结论HA与β-TCP均具有良好的骨引导作用,可用于上颌窦底提升植骨中良好的骨替代材料,可维持种植体的长期稳定,值得推广使用。

Objective:To analyze the osteogenic effect of hydroxyapatite(HA)and β-tricalcium phosphate(β-TCP)bone graft materials and the clinical effect of maxillary sinus enhanced implant repair function load.Methods:From March 2019 to March 2022,20 patients who underwent maxillary sinus lifting bone grafting at the same time of implant implantation in the Department of Stomatology,Affiliated Hospital of Chengde Medical University were selected as the study objects.All patients were implanted with HA and β-TCP bone materials.The postoperative implant retention rate and related complications of patients were observed,and the bone volume around the implant was observed 1 and 6 months after surgery.Results:In 20 patients(23 implants),6 months after implant implantation,imaging examination showed that the bone union between implant and alveolar bone was good,and the retention rate of implant was 100%.The height of buccal and proximal distal maxillary sinus mucosal floor in HA+β-TCP patients was significantly lower than that in HA+β-TCP patients at 6 months after the operation(P<0.05).Conclusion:Both HA and β-TCP have good bone guiding effect,and can be used as good bone replacement materials in maxillary sinus bottom lifting bone grafting,which can maintain the long-term stability of implants,and are worthy of popularization.
