摘要: 目的: 评价单纯上颌窦内提升植入种植体在上颌后牙区骨量严重不足的临床效果,比较上颌窦内提升同期植骨与否的疗效。方法: 选择28例上颌后牙区缺失患者,剩余牙槽骨高度<7 mm,共植入40颗ITI种植体。其中植入部位RBH<4 mm种植体6颗,RBH 4~7 mm种植体34颗;行单纯上颌窦内提升植入种植体24颗(内提升不植骨组),行上颌窦内提升植骨同期植入种植体16颗(内提升植骨组)。测量各病例术后6~12个月的骨提升高度。采用SPSS19.0软件包对数据进行配对样本t检验。结果: 28例40颗种植体初期稳定性佳,骨结合良好,种植成功率100%。RBH<4 mm组与RBH 4~7 mm组术前剩余牙槽骨高度分别为(3.44±0.57)mm和(5.50±1.00)mm,术后提升骨量分别为(7.91±1.06)mm和(8.77±1.15)mm,2组比较无显著差异(P>0.05);内提升不植骨组与植骨组术前剩余牙槽骨高度分别为(5.07±1.19)mm和(5.37±1.24)mm,术后提升骨量分别为(8.47±1.18)mm和(8.89±1.13)mm,2组比较无显著差异(P>0.05)。结论: 上颌窦内提升在RBH<4mm条件下能够成功,提升效果与常规内提升接近。进行单纯上颌窦内提升术创伤小、费用更低,且对于上颌后牙区提升骨量有效。

Abstract: PURPOSE: To evaluate the clinical effect of simple osteotome sinus floor elevation without bone grafting in the posterior maxilla area with less bone height. METHODS: Twenty eight cases with posterior maxillary bone deficiency were included.Their residual alveolar bone height (RBH) was less than 7 mm. 40 ITI implants were implanted. Among them, 6 implants were implanted in the sites with RBH less than 4 mm (group 1), 34 were implanted in the sites with RBH between 4 to 7 mm (group 2).16 implants were inserted with bone graft, while 24 implants were inserted without bone graft. 6~12 months after operation, the alveolar bone height were measured and recorded. SPSS19.0 software package was used for data analysis. RESULTS: All 40 implants in 28 patients had good initial stability and good osseointegration, the success rate was 100%. RBH in group 1 and group 2 was (3.44±0.57) mm, (5.50±1.00) mm, respectively; postoperative bone increase was (7.91+1.06) mm in group 1, (8.77+1.15) mm in group 2, respectively (P>0.05).Preoperative RBHin bone graft group was (5.37±1.24) mm and (5.07±1.19) mm in patients without bone graft. Postoperative bone increase was (8.47±1.18) mm in bone graft group, and (8.89±1.13)mm in patients without bone graft, responsively (P>0.05). CONCLUSIONS: Maxillary sinus elevation can be successfully performed in patients with RBH<4 mm, and the effect is similar to that of conventional maxillary sinus lifting. Simple osteotome sinus floor elevation without bone grafting, which is with less trauma and lower cost, is effective in improving bone height in posterior maxillary region.
