摘要
目的 :评价黄金比例在上颌窦外提升术及同期种植体植入术中的应用效果。方法 :选择2016年7月—2017年10月青岛大学附属医院西海岸院区种植科上颌磨牙缺失且剩余牙槽骨高度(residual bone height,RBH)约2.0~5.0 mm的患者15例,进行上颌窦外提升术。采用黄金比例确定种植体长度为11~12 mm,行同期种植体植入术,追踪其术后3~6个月愈合及骨结合情况。结果 :15例患者共植入21颗种植体,患者自我感觉良好。影像学检查可见种植体与周围骨组织结合良好,无1例患者发生上颌窦炎、种植体松动、脱落或种植体周围炎等并发症。术后6个月行种植修复,所有患者均能正常行使咀嚼功能,种植体周围软组织色泽、形态、质地无改变。结论:运用黄金比例在上颌窦外提升术后同期植入种植体,可有效解决上颌后牙区RBH严重不足问题,为种植体长度选择提供依据。
PURPOSE： To investigate the clinical value of golden ratio in maxillary sinus augmentation and simultaneous implantation. METHODS： Fifteen patients were enrolled with missing maxillary molars and residual bone height（RBH）about 2.0-5.0 mm from Jul. 2016 to Oct. 2017 at the Department of Implantology in the Affiliated Hospital of Qingdao University of West Coast District. The patients underwent maxillary sinus augmentation and simultaneous implantation and followed up for 3-6 months. Golden ratio was used to select the length of implants about 11-12 mm. RESULTS： A total of 21 implants were placed in 15 patients. All patients had good osseointegration of the implants and the surrounding bony tissues on imaging, and none of them had complication, such as maxillary sinusitis, loose implant, peri-implantitis, etc. Six months after operation, restoration was performed, the patients had satisfactory masticatory function and normal soft tissues around the implants. CONCLUSIONS： Application of golden ratio in maxillary sinus floor elevation and simultaneous implantation can solve insufficient RBH in posterior maxillary area, and provide reliable reference for selection of implant length.
