What are the anatomical landmarks for IANB?
[1,20,21] The most important clinical landmarks used in the location of the inferior alveolar nerve block 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.
Where do you inject inferior alveolar nerve block?
Inject the local anesthetic
Place and maintain the barrel of the syringe over the contralateral lower 1st and 2nd premolars. Keep the needle parallel to—and about 1 cm above—the mandibular occlusal plane, at the vertical plane of the coronoid notch.
What is Gow Gates technique?
The Gow-Gates technique requires the patient’s mouth to be open wide, and the dentist aims to administer local anesthetic just anterior to the neck of the condyle in proximity to the mandibular branch of the trigeminal nerve after its exit from the foramen ovale.
Where is the coronoid notch?
The finger or thumb on your retracting hand palpates the external oblique ridge until it is at the greatest depth, which is the coronoid notch.
Where do dentists inject lidocaine?
The dentist is experienced and trained in how to find these nerves. If only a single tooth will be treated, the dentist may only have to make one injection. The syringe will be inserted at the area near the tip of the your tooth’s root, in the seam where your gum line connects to the beginning of your lip.
What is Gow-Gates numb?
The Gow-Gates anesthetizes the inferior alveolar and its terminal branches (incisive and mental), lingual, mylohyoid, auriculotemporal, and the buccal nerve 75% of the time.
What is the target area for the inferior alveolar nerve block?
When administering the inferior alveolar block, the target area lies on the medial surface of the mandibular ramus at the inferior tip of the pterygomandibular triangle and adjacent to where the inferior alveolar nerve exits the mandible.

What is an incisive nerve block?
The mental incisive nerve block (MINB) is a technique used to anesthetize mandibular premolars by injection anesthetic solution near the mental foramen to block the mental incisive nerve (Aggarwal et al., 2016, Batista da Silva et al., 2010, Ghabraei et al., 2019).
Where is the mandibular notch?
The mandibular notch is a concave groove at the top of the ramus of the mandible. It is the gap between the coronoid process anteriorly and the condyloid process posteriorly.
What is radial notch?
noun. : a narrow depression on the lateral side of the coronoid process of the ulna that articulates with the head of the radius and gives attachment to the annular ligament of the radius.
Which needle has the smallest lumen?
The gauge size of a needle indicates what the diameter of the lumen (opening) is. The higher the gauge, the smaller the diameter. For example, a 30 gauge needle has a narrower lumen than a 25 gauge needle.

What happens if a dental injection hits a nerve?
Some of the signs of nerve damage after receiving a dental injection may include: A lack of sensation in the area treated even after the anaesthetic should have worn off. Numbness or lack of feeling in the tongue, gums, cheeks, jaw or face. A pulling or tingly sensation in these areas.
What does Akinosi block anesthetize?
WHAT IS IT? The Vazirani-Akinosi (VA) is a mandibular nerve block which anesthetizes all teeth in the quadrant injected. This includes the periodontium and gingival tissue from the third molar to midline along with the lingual tissue and half of the tongue.
What does the IAN block?
Background: Inferior alveolar nerve block (IANB) is a technique of dental anesthesia, used to produce anesthesia of the mandibular teeth, gingivae of the mandible and lower lip. The conventional IANB is the most commonly used the nerve block technique for achieving local anesthesia for mandibular surgical procedures.

Why do we aspirate when giving local anesthetic?
Aspiration is recommended before the injection of local anesthetic to prevent accidental intravascular deposition and potentially generate undesirable local and/or systemic effects or complications.
Why do we aspirate in two planes?
Before injecting, one should aspirate in two planes to avoid accidental injection into the pterygoid plexus. After the first aspiration, the needle should be rotated one-quarter turn. The operator should then re-aspirate.
How do you give a maxillary nerve block?
Retracts the cheek with a tongue depressor, while the patient keeps their mouth open. Inserts the needle near the gum of the second upper molar, parallel to the cheek. Advances the needle into the depression under the cheek bone (pterygopalatine fossa). Slowly injects the anesthetic and withdraws the needle.

What is masseteric notch?
The masseteric artery is a small branch that passes through the mandibular notch of the mandible into the deep surface of the masseter muscle. The masseteric artery anastomoses with branches of the facial artery (formerly the external maxillary artery) and the transverse facial artery.[2]
Where is sigmoid notch located?
The mandibular notch, also known as the sigmoid notch, is a groove in the ramus of the mandible. It is the gap between the coronoid process anteriorly and the condyloid process posteriorly.
Where is the ulnar notch?
radius
Description. The articular surface for the ulna on the lower extremity of the radius is called the ulnar notch (sigmoid cavity) of the radius; it is narrow, concave, smooth, and articulates with the head of the ulna.
Is radial notch medial or lateral?
lateral
The Upper Limb
Proximally, the radial notch is located on the lateral side. In the shaft, the sharp interosseous border is lateral. The nutrient foramen is usually in the centre of the anterior upper half with its entrance directed proximally. Distally, the medial surface is slightly concave.
