Anesthesia is an insymural method commonly used in tooth extraction or oral minor surgery. Depending on the complexity of the case, the doctor will choose appropriate anesthesia techniques such as surface anesthesia, local anesthesia, regional anesthesia.

1. What is regional anesthesia?

Regional anesthesia is a technique of numbing nerve axes or blocking the segment of nerves that govern sensation in a relatively large area. Regional anesthesia has the effect of numbing an area dominated by nerves.

The advantage of this method is that only one injection is required with a moderate amount of anesthesia but achieves a widespread and prolonged level of numbness. The technique is applied in dentistry when pulling difficult teeth, pulling out multiple teeth at a time or when the place where the teeth need to be pulled has an inflammation.

2. Anaesthetic techniques in dentistry

2.1 Regional anesthesia in the upper jaw

Upper tooth nerve anesthesia

Anesthesia is performed on the back of the upper molars

Anesthesia of the upper tooth nerve is carried out as follows

  • The patient is lying on his back in a 45o position, his mouth is small, the treater uses his index finger in the mouth to bulge the upper jaw bone, the back edge.
  • Inserting a 42mm needle into the tip of the outer wisdom root, keeping the needle close to the bone and threading the needle up and out behind the 45o always holds the needle close to the bone, pushing the needle about 2cm deep (the bone tumor is a curved ring).
  • Squeeze the needle and pump the anesthetic and at the end of the pump the rest, all about 2ml.

The anaesthetic area includes:

  • Pulp 6 , 7 , 8 upper jaw except for the outer leg near the tooth no. 6.
  • Bone socket and organization of the link, mucous membranes on the cheeks.

Anesthesia of the upper back tooth nerve (H.4)

Upper tooth nerve anesthesia

Anesthesia of the front aperture nerve (in the back aperture hole)

The technique consists of the following steps:

  • Determination of the rear aperture hole at the edge in the wisdom tooth
  • Pierce the needle from front to back and slightly tilt outwards.
  • Pump 0.5 ml of anesthesia, short numbness of about 30 minutes.

The numb area is the arch of the tooth area.

Nasal nerve anesthesia – female aperture (in the front aperture hole)

When performing nasal nerve anesthesia – the patient's mouth is required to open his mouth, head back. The technician identified the front aperture hole in the middle of the aperture arch and behind the middle inciser lcm. After that, the technician inserts the needle in the position above the needle upwards and back, goes 1/4 – 1/2 cm deep and then pumps 0.5 – 1ml of anesthetic. Numbness occurs after about 3 minutes and lasts for 30 minutes.

This technique helps to anesthesia the fibromeal mucosa of the palate behind the incis and canines.

2.2 Regional anesthesia in the lower jaw

Lower tooth nerve anesthesia (H.6,7,8,9) (in Spix hemp holes) is contrained in the following cases:

  • Stiffening of the jaws.
  • Infection of the lower jaw bone.

Chin nerve anesthesia

When performing the chin nerve anesthesia technique, the patient is required to slightly bow forward, at which point the technician's hand can detect the chin hole. Then, pierce the needle into the bottom of the corridor opposite the 5th tooth at an angle of 15° from the front to the back of the tooth shaft. Put a 2 – 3mm deep needle in the chin hole and pump 1.5 – 2ml of the drug.
