目的评估上后牙区牙缺失后剩余牙槽骨高度不足5 mm时运用冲压法上颌窦底提升术进行种植修复是否安全可靠。方法选择2011年1月至2014年1月于第四军医大学口腔医院口腔种植科行种植修复的上颌后牙区缺牙后牙槽嵴严重萎缩(剩余牙槽骨高度不足5 mm)病例26例,均采用冲压法上颌窦底提升术植入植骨材料并同期植入种植体,收集患者影像学资料并测量种植体周软组织指数,进行回顾性研究。分别测量术后及最终修复体戴入1年后随访时的边缘骨水平、根尖骨高度及软组织指数并进行分析。结果共35颗种植体纳入本研究,边缘骨吸收为(1.21±0.40)mm,术后根尖骨高度为(1.33±0.52)mm,随访时根尖骨高度为(1.20±0.52)mm,随访时根尖骨高度较种植体植入后降低,且差异有统计学意义(P<0.05)。随访时35颗种植体的改良菌斑指数(mPLI)为1.46±0.78,改良出血指数(mSBI)为1.26±0.74。结论当上颌后牙区剩余牙槽骨高度不足5 mm时,可运用冲压法上颌窦底提升术植入种植体,其效果较为满意。
Objective To assess the safety and reliability of dental implants using stamping maxillary sinus floor augmentation when residual alveolar bone height is less than 5 mm in the posterior teeth. Methods From January 2011 to January 2014, 26 patients with severe atrophy of the alveolar ridge (the remaining alveolar height less than 5 mm) were implanted in the maxillary posterior teeth of the maxillofacial region implanted in the Stomatology Hospital of the Fourth Military Medical University. , Were implanted using maxillary sinus floor elevation implantation of implants and implantation of implants at the same period, the imaging data were collected and measurement of peri-implant soft tissue index, a retrospective study. The level of marginal bone, the height of apical bone and the index of soft tissue at the follow-up of 1 year after operation and the final restoration were measured and analyzed. Results A total of 35 implants were included in this study. The marginal bone resorption was (1.21 ± 0.40) mm, the height of postoperative apical bone was (1.33 ± 0.52) mm, and the height of apical bone was (1.20 ± 0.52) mm at follow-up The height of apical bone decreased after implants, and the difference was statistically significant (P <0.05). At follow-up, the modified plaque index (mPLI) of 35 implants was 1.46 ± 0.78 and the mSBI was 1.26 ± 0.74. Conclusion When the height of the remaining alveolar bone in the maxillary posterior teeth area is less than 5 mm, the implants can be implanted using the maxillary sinus floor elevation method. The effect is satisfactory.
