Maxillary Injection Techniques used in Dental Treatments

There are several anesthetic techniques that are used to provide the anesthetic effect to carry about the various treatment procedures in the maxillary region. These techniques differ in their areas, i.e. the teeth, hard and soft tissues or altogether based on the procedure that has to be carried out. These Local anesthesia injection techniques like infiltrations or Blocks are required in simple procedures such as Scaling and Root Planning to complex procedures like the treatment of fractures, Wisdom tooth removal surgery, Flap surgery Enucleation of cyst etc. 

Check out the Composition of local anesthesia, and the properties of ideal LA agent, before you learn about the various anesthetic procedures used to anesthetize the maxillary areas for the treatment procedures.

Maxillary Injection for Local Anesthesia

Following are the various Maxillary injection techniques that are carried out based on the nature of the dental treatment:

• Supraperiosteal (Infiltration) technique: This is a less commonly used technique which is used in limited treatment protocols
• Intraseptal injection: This is one of the types of injection techniques used for the periodontal surgical techniques
• Intracrestal injection: This technique is secondarily used in the techniques which involve a single tooth, where the other techniques have failed to produce the anesthetic effect
• Periodontal Ligament injection: (Also PDL, intraligamentary injection: This cannot again be used as one of the standard techniques but just as an adjunct to the different techniques with limited treatment protocols
• Intraosseous injection: This is another alternative technique used for the single tooth treatment procedures when the other ones have failed
• Posterior Superior Alveolar Nerve Block (PSAN): This is a nerve block technique which is capable of anesthetizing the molar teeth on one quadrant, i.e. maxillary 1st, 2nd and 3rd molars
• Middle Superior Alveolar Nerve Block (MSA): This technique is to anesthetize the Middle superior alveolar nerve which supplies the pre-molar teeth, and these are the teeth which are anesthetized based on the side where it is given
• Anterior Superior Alveolar Nerve Block (ASA) / Infraorbital Nerve Block: This technique is used to anesthetize the anterior teeth on one quadrant
• Greater (Anterior) Palatine Nerve Block: This technique is mainly used for the anesthesia of the palatal soft tissues and the osseous tissue treatment distal to the canine in one quadrant.
• Nasopalatine Nerve Block: This block is recommended for the palatal soft- and osseous-tissue management from canine to canine bilaterally
• Anterior Middle Superior Alveolar (AMSA) Nerve Block: This block is for the anterior teeth, palatal and buccal soft and hard tissue management and is it recommended for the extensive management
• Maxillary (second division) Nerve Block: This block is used for the extensive buccal, palatal, pulpal management in one quadrant
• Palatal approach – Anterior Superior Alveolar Nerve Block (P-ASA): This block is recommended for the treatment of maxillary anterior teeth, their palatal and facial soft and hard tissues

The ways such as the Supraperiosteal, periodontal ligament, intraseptal and intraosseous injections are appropriate for both the maxillary and mandibular tissues.
