2种羟基磷灰石复合材料在上颌窦内提升术植骨同期植入种植体中的临床效果

目的: 比较2种羟基磷灰石复合材料在上颌窦内提升术植骨同期植入种植体中的临床效果。方法: 收集2018年3月—2019年4月蚌埠医学院第一附属医院收治的上颌后牙区种植、骨量不足患者72例,以随机数字表法分为实验组（36例）和对照组（36例）,对照组放置羟基磷灰石复合材料,实验组放置纳米羟基磷灰石复合材料。比较2组种植体植入的临床效果、骨增量、骨密度等情况,统计2组术后种植体稳定性及并发症发生情况。采用SPSS 18.0软件包进行统计学分析。结果: 实验组24个月的种植体存留率显著高于对照组（P<0.05）,实验组术后6个月的牙槽骨骨吸收量显著低于对照组（P<0.05）,实验组术后6个月、12个月的种植体牙槽骨骨密度显著高于对照组（P<0.05）,实验组术后12个月的种植体稳定系数值显著高于对照组（P<0.05）。2组术后总并发症发生率相比无统计学差异（P>0.05）。结论: 上颌窦内提升术放置纳米羟基磷灰石复合材料同期植入种植体存留率高,可改善术后骨代谢,增强种植体稳定性,且安全性良好。

Clinical effects of two different hydroxyapatite bone graft materials during maxillary sinus lifting surgery with bone grafting and simultaneous implantation of implants

PURPOSE: To compare the clinical effects of two different hydroxyapatite bone graft materials in maxillary sinus lifting surgery with bone grafting and implantation at the same time. METHODS: Seventy-two patients with implantation in the maxillary posterior dental area and insufficient bone mass admitted to the First Affiliated Hospital of Bengbu Medical College were collected from March 2018 to April 2019, and they were divided into experimental group(n=36) and control group(n=36) by random number table. Patients in the control group used hydroxyapatite composite material, while patients in the experimental group used nano-hydroxyapatite composite material. The clinical effects, bone increment and bone density changes of the two groups of implants were compared, and postoperative implant stability and complications of the two groups were compared. Statistical analysis was performed with SPSS 18.0 software package. RESULTS: The survival rate of implants in the experimental group was significantly higher than that in the control group at 24 months (P<0.05). Alveolar bone resorption in the experimental group was significantly lower than the control group 6 months after surgery(P<0.05). The bone mineral density of implants in the experimental group was significantly higher than the control group 6 months and 12 months after operation(P<0.05). The implant stability coefficient value of the experimental group was significantly higher than the control group 12 months after operation(P<0.05). There was no significant difference in the total complication rate between the two groups(P>0.05). CONCLUSIONS: In maxillary sinus lift, the survival rate of nano-hydroxyapatite composite material implanted in the same period is high, which can improve postoperative bone metabolism and increase implant stability with good safety.
