Local anesthesia fails in 10% of cases of inferior alveolar nerve block and 7% of all cases of local anesthesia in general practice. Possible causes of failure are infection, wrong selection of local anesthetic solution, technical mistakes, anatomical variations with accessory innervation and anxiety of the patient. In this publication we discuss reasons for frequent failure in case of infection and in inferior alveolar nerve block. Understanding the mechanism of failure in local anesthesia, makes it possible to formulate guidelines to guarantee success. These measures are discussed in detail.
在一般牙科实践中，下牙槽神经阻滞麻醉有10%的病例失败，局部麻醉总体失败率为7%。失败的可能原因包括感染、局部麻醉剂溶液选择错误、技术失误、存在副神经支配的解剖变异以及患者焦虑。在本出版物中，我们讨论了感染和下牙槽神经阻滞麻醉时频繁失败的原因。了解局部麻醉失败的机制有助于制定确保成功的指南。这些措施将详细讨论。
