摘要/Abstract

摘要： 目的：观察Astra锥形植体在上颌窦穿牙槽嵴顶提升术中的短期临床疗效。方法：纳入2019年3月—2019年9月40例上颌后牙缺失、需行上颌窦穿牙槽嵴顶提升术的患者,剩余骨高度为2~8 mm。于缺牙区植入Astra锥形种植体,术后4个月完成上部结构修复。观察种植体留存率、种植体稳定性、种植体边缘骨吸收以及上颌窦成骨量。采用SPSS 19.0软件包对数据进行统计学分析。结果：随访期内,40例患者共植入44颗种植体,种植体1年留存率为100%。术后即刻测量的ISQ值为67.55±8.07,初戴时ISQ值为79.62±5.08,随访期间ISQ值平均变化值为12.07±5.86。种植体周围边缘骨吸收(0.32±0.29) mm,术后至12个月间平均上颌窦成骨量(1.06±0.4) mm。未发现机械并发症。种植体周围探诊深度均值为(3.2±1.51) mm,探诊出血率为(11.36±4.28)%,改良菌斑指数均值为1.23±0.43。结论：Astra锥形植体在上颌窦穿牙槽嵴顶提升术中能够获得良好的临床效果,但仍需更长随访时间的研究验证。

Abstract: PURPOSE: The aim of this study was to evaluate the short-term clinical outcome of tapered implants placed in posterior maxilla with osteotome sinus floor elevation (OSFE) technique. METHODS: The study population comprised 40 patients in whom 44 Astra tapered implants were inserted with OSFE technique from March to September in 2019. The surgical indication was that the bone height below the maxillary sinus was considered to be 2mm ~8mm. Astra tapered implants were inserted. Prosthetic restoration was completed 4 months after surgery. The implant success rate and stability, as well as osseointegration of the implant were clinically evaluated, and bone gain around the implants were measured. The data were analyzed using SPSS 19.0 software package. RESULTS: During the study period,the implant survival rate was 100%. The mean variation of implant stability quotient(ISQ) was 12.07±5.86. The mean value of ISQ ranged from 67.55±8.07 to 79.62±5.08. The average marginal bone loss was (0.32±0.29) mm. The endo-sinus bone gain(ESBG) was (1.06±0.4) mm. No mechanical complication was observed. The average probing depth around the implant was (3.2±1.51) mm, the bleeding on probing rate was(11.36±4.28)%, and the modified plaque index was 1.23±0.43. CONCLUSIONS: Astra tapered implants were found to produce predictable results in osteotome sinus floor elevation surgery. Further properly designed clinical trials are required to validate the use of tapered dental implants in sinus floor elevation technique.
