Abstract：
OBJECTIVE: To evaluate the survival rates of dental implants with a hybrid macrostructure and the surface biomimetically coated with nanohydroxyapatite, placed in horizontally atrophic maxillae previously submitted to the guided bone regeneration (GBR) procedure, associated with the use of a deproteinized bovine bone graft (DBB).
METHODS: Twenty-five patients who received 196 implants were involved in this study. First, these patients were submitted to GBR procedures and maxillary sinus lift, where DBB was used as the grafting material. The dental implants were placed after a minimum period of 6 months of the grafting procedures. The patients were followed up every six months and clinical/radiographic examinations were performed to assess the implants, using the following indicators as a reference: (1) Absence of mobility; (2) Absence of pain. Data about the age, surgery time, smoking status, implant size, and time between the grafting procedure and implant placement were correlated with implant failures.
RESULTS: Twelve implants failed, generating a survival rate of 94.23%. None of the variables analysed correlated with the implant failures.
CONCLUSIONS: Implants with a hybrid macrostructure and surface biomimetically coated with nanohydroxyapatite present good survival rates in horizontally atrophic maxillae grafted with DBB.

摘要：
目的：评估具有混合宏观结构和表面仿生涂覆纳米羟基磷灰石的牙种植体的存活率，放置在先前接受引导骨再生（GBR）程序的水平萎缩性上颌骨中，与使用脱蛋白牛骨移植物（DBB）有关。
方法：25名接受了196个植入物的患者参与了这项研究。首先,这些患者接受了GBR手术和上颌窦提升术，其中使用DBB作为接枝材料。在至少6个月的移植程序后放置牙植入物。每六个月对患者进行随访，并进行临床/影像学检查以评估植入物，使用以下指标作为参考:(1)没有活动;(2)没有疼痛。关于年龄的数据，手术时间,吸烟状况,植入物大小,移植程序和植入物放置之间的时间与植入物失败相关。
结果：12个植入物失败，产生94.23%的存活率。分析的变量中没有一个与植入物失败相关。
结论：具有混合宏观结构和表面仿生涂有纳米羟基磷灰石的植入物在用DBB移植的水平萎缩性上颌骨中具有良好的存活率。
