How do you give a maxillary nerve block?

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.

Which anesthetic methods should be used in extraction of maxillary premolars?

The common techniques for providing anesthesia in maxillary molars include posterior superior alveolar (PSA) nerve block and infiltration anesthesia (6).

What injection is commonly used for maxillary teeth?

The techniques most commonly used in maxillary anesthesia include supraperiosteal (local) infiltration, periodontal ligament (intraligamentary) injection, PSA nerve block, MSA nerve block, anterior superior alveolar nerve block, greater palatine nerve block, nasopalatine nerve block, local infiltration of the palate.

How do you administer maxillary infiltration?


  1. Retract the cheek so the tissue of the mucobuccal fold is taut.
  2. Apply topical anesthetic.
  3. Orient the needle bevel toward the bone.
  4. Penetrate the mucosa labial to the tooth to be treated close to the bone at the mucogingival margin with the syringe parallel to the long axis of the tooth.
  5. Aspirate.

How do you anesthetize maxillary first molar?

Retract the cheek so the tissue of the mucobuccal fold is taut. Apply topical anesthetic. Orient the needle bevel toward the bone. Penetrate the mucous membrane and slowly advance the needle until its tip is above the area between the apices of the first molar or above the apex of the second premolar.

How do you anesthetize maxillary incisors?

Figure 11. Local Infiltration of the Maxillary Primary and Permanent Incisors and Canines

  1. If it is necessary to anesthetize an adjacent tooth, partially withdraw the needle and turn the needle in the direction of the indicated tooth in advance the needle until it approximates the apex.
  2. Aspirate.

What is vazirani Akinosi?

Background: Vazirani-Akinosi nerve block technique is an established and a reliable technique to achieve anaesthesia in mandible with high success rate and is useful in cases where Halstead’s technique fails to provide desired anaesthetic effect.

What does Akinosi block anesthetize?

Therefore, the V-A block will anesthetize the mandibular teeth to the midline and associated lingual periodontium and gingiva, as well as the facial periodontium and gingiva of the mandibular anterior teeth and premolars to the midline and possibly the buccal periodontium and gingiva of the mandibular molars within one …

Why the maxillary injections are easier to anesthetize?

The maxillary bone is less dense and more permeable than the mandible, which facilitates anesthesia by supraperiosteal injection (administered above tooth apex),4,5 especially with the use of 4% articaine.

What type of anesthesia injection would be used to anesthetize a single maxillary tooth?

The V2 block injection anesthetizes the maxillary teeth and periodontium, hard and soft palates, sinuses, and portions of the nose, orbit, upper cheek, lower eyelid, and side of the face.

What are the options for maxillary anesthesia?

Maxillary Anesthesia: Acessory • Supraperiosteal (infiltration) • Periodontal ligament (PDL, intraligamentary) injection • Intraseptal injection • Intracrestal injection, • Intraosseous (IO) injection 18.

How to correct inadequate anesthesia in the area of maxillary first premolar?

• Inadequate anesthesia in the area of the maxillary first premolar: overlapping fibers from the nasopalatine nerve (partial success). – To correct: Local infiltration may be necessary as a supplement in the area of inadequate anesthesia.

What areas of the mouth are anesthetized during a tooth extraction?

Areas Anesthetized • Anterior portion of the hard palate (soft and hard tissues) bilaterally from the mesial of the right first premolar to the mesial of the left first premolar 82.

What is the maxillary nerve?

Maxillary Anesthesia Dr. Deepak K. Gupta 2. Maxillary Nerve • Second division of the trigeminal nerve arises from the middle of the trigeminal ganglion. • Intermediate in size between ophthalmic and mandibular divisions, • It is purely sensory in function • Leaves the cranium through the foramen rotundum. 4.
