Buccal nerve block (long buccal nerve block) is indicated for procedures involving the mucosa adjacent to the posterior molar teeth, such as the placement of a rubber dam clamp. The injection site is distal and buccal to the third molar, with the needle penetrating 1-2mm as the nerve lies directly below the mucosa. [ 5 ]
Infiltration analgesia is deposition of an analgesic (pain-relieving) drug close to the apex of a tooth so that it can diffuse to reach the nerve entering the apical foramina. [1] It is the most routinely used in dental local treatment.
The buccal branches of the facial nerve (infraorbital branches), are of larger size than the rest of the branches, pass horizontally forward to be distributed below the orbit and around the mouth. Branches
The method is similar to the maxillary buccal infiltration. Ensure the lip/ cheek is stretched in a lateral and inferior direction instead of superiorly and the needle is then penetrated 45' with the buccal cortical plate of the bone through the taut tissue of the muccobuccal fold. Tooth to be anaesthetised [5]
Inferior alveolar nerve block (abbreviated to IANB, and also termed inferior alveolar nerve anesthesia or inferior dental block) is a nerve block technique which induces anesthesia (numbness) in the areas of the mouth and face innervated by one of the inferior alveolar nerves which are paired on the left and right side.
The gingiva on the facial aspect of the mandibular incisors and canines is innervated by the mental nerve, the continuation of the inferior alveolar nerve emerging from the mental foramen. The gingiva of the buccal (cheek) aspect of the mandibular molar teeth is innervated by the buccal nerve (long buccal nerve). [7]
The risk of nerve injury in relation to mandibular dental implants is not known but it is a recognised risk requiring the patient to be warned. [10] If an injury occurs urgent treatment is required. The risk nerve injury in relation deep dental injections has a risk of injury in approximately 1:14,000 with 25% of these remaining persistent.
