There is a lack of evidence regarding success of implants placed in atrophic premaxilla using the nasal floor elevation technique.
This study aimed to compare implants placed in augmented bone in the anterior maxilla using the nasal floor elevation technique with implants placed in the maxillary sinus region using the sinus lift technique.
A within-patient controlled clinical trial was performed on 14 patients receiving 78 implants. The implants were assigned to one of two study groups on the basis of implant location. A total of 37 implants were placed in the nasal fossa region (NF group), and 41 implants were placed in the maxillary sinus region (MS group). Patients were followed up for 4.5 ± 2.2 years, with comparable follow-up times for implants in NF and MS groups (4.7 ± 2.1 and 4.9 ± 2.1 years, respectively; p > .05). Treatment outcomes were assessed and statistically analyzed.
Implant success rate was 89.2% in the NF group and 95.0% in the MS group, with no statistically significant difference between them (p > .05). No nasal or sinus membrane perforation or other complications were reported within the follow-up period. Significant differences were found between the two groups in terms of residual bone height, augmented bone height, and implant diameter.
Nasal floor elevation is an effective and safe procedure that can be used for implant placement in atrophic premaxilla with success rates that are comparable to those of implants placed in the maxillary sinus.
关于使用鼻底提升技术在上颌前牙区萎缩骨中植入种植体的成功率，目前缺乏相关证据。
本研究旨在比较使用鼻底提升技术在上颌前牙区增骨后植入的种植体与使用上颌窦提升技术在上颌窦区域植入的种植体。
对14例接受78颗种植体植入的患者进行了一项患者自身对照临床试验。根据种植体位置将种植体分配到两个研究组之一。共37颗种植体植入鼻窝区域（NF组），41颗种植体植入上颌窦区域（MS组）。患者随访4.5±2.2年，NF组和MS组种植体的随访时间相当（分别为4.7±2.1年和4.9±2.1年；p＞0.05）。对治疗结果进行评估并进行统计学分析。
NF组种植体成功率为89.2%，MS组为95.0%，两组间无统计学显著差异（p＞0.05）。随访期间未报告鼻或鼻窦黏膜穿孔或其他并发症。两组在剩余骨高度、增骨高度和种植体直径方面存在显著差异。
鼻底提升是一种有效且安全的手术方法，可用于在上颌前牙区萎缩骨中植入种植体，其成功率与在上颌窦植入种植体相当。
