Infiltration

A local anesthetic procedure effective for upper teeth and soft tissue or the placement of anesthetic under the gum, allowing it to seep into bone. Infiltration analgesia is deposition of an analgesic drug close to the apex of a tooth so that it can diffuse to reach the nerve entering the apical foramina. It is the most routinely used dental local treatment. In the maxillary arch nerves for infiltration are branches of the superior alveolar, the greater palatine and the nasopalatine nerve: Posterior superior alveolar nerve supplies the molars (not including the mesiobuccal root of the maxillary first molar), the surrounding bone, periodontal ligament, periosteum and buccal soft tissues. Middle superior alveolar nerve supplies the premolars and the mesiobuccal root of the maxillary first molar, the surrounding bone, periodontal ligament, periosteum and buccal soft tissues Anterior superior alveolar nerve supplies the anterior canines and incisors, the surrounding bone, periodontal ligament, periosteum and buccal soft tissues.
