Abstract
"Risks and Performance of a New Guiding Device for Inferior Alveolar Nerve Block, EZ-Block®, Compared to Traditional Free Hand Techniques: A Pilot Study"
Highlights
In spite of a high failure rate and risk of complications, the inferior alveolar nerve block (IANB) is the most common anesthesia technique used in dentistry
The trismus rate is higher with the EZ-Block®, it remains within the same range
The clinical data of the EZ Block® allow to evaluate the performance and the safety of the device. This pilot study should be complemented with a larger clinical study to confirm the effectiveness of the device
Summary
In spite of a high failure rate and risk of complications, the inferior alveolar nerve block (IANB) is the most common anesthesia technique used in dentistry. The guiding medical device EZ-Block®, which relies on extra-oral landmarks easy to identify, would increase performance rate and reduce risks of IANB. Some important intraoral landmarks need to be identified by the operator in order to reduce the percentage of failure following the use of this technique [1]. The most important clinical intra-oral landmarks used in the location of the IANB are the coronoid notch and the pterygomandibular raphe. The preferred site of needle insertion lies between these two landmarks, and the point of insertion is determined by simple measurements: it is located on an imaginary line drawn from the deepest part of the pterygomandibular raphe to the coronoid notch
