A systematic review was conducted to evaluate the success rate of dental implants placed in the incisive canal region and the complications related to this procedure. An electronic search was performed in the PubMed, Scopus, and Web of Science databases. Articles reporting the incisive canal deflation technique or neurovascular bundle lateralization technique, with or without concomitant dental implant installation and grafting procedures, were evaluated. Ten articles met the inclusion criteria; only one retrospective study and one longitudinal clinical trial were found. A total of 91 implants were installed in this region, and implant success ranged from 84.6% to 100%. With regard to complications, three articles reported temporary sensory loss. Permanent sensory loss in the palatal mucosa region was reported in one study applying neurovascular bundle lateralization. Five studies were assessed in the quality analysis: four were of moderate quality and one was of low quality. Although a high success rate was described in the selected studies, caution is recommended when dental implants are installed in the incisive canal region due to the low level of evidence available. Regarding complications, there are no parameters for predicting the occurrence of sensory disturbances or the extent of damage with the use of incisive canal deflation or neurovascular bundle lateralization.
进行了一项系统评价，以评估在切牙管区域植入牙种植体的成功率以及与该手术相关的并发症。在PubMed、Scopus和Web of Science数据库中进行了电子检索。对报告切牙管减压技术或神经血管束侧方移位技术（无论是否同时进行牙种植体植入和植骨手术）的文章进行了评估。有10篇文章符合纳入标准；仅发现1项回顾性研究和1项纵向临床试验。该区域共植入了91颗种植体，种植成功率在84.6%至100%之间。关于并发症，3篇文章报告了暂时性感觉丧失。在一项应用神经血管束侧方移位的研究中报告了腭黏膜区域的永久性感觉丧失。在质量分析中评估了5项研究：4项质量中等，1项质量低。尽管在所选研究中描述了较高的成功率，但由于现有证据水平较低，在切牙管区域植入牙种植体时建议谨慎操作。关于并发症，在使用切牙管减压或神经血管束侧方移位时，没有预测感觉障碍发生或损伤程度的参数。
