Injury of inferior alveolar nerve part 1

It is one of the most dangerous injuries in dentistry. Damaging of inferior alveolar nerve mostly occurs during filling channels, removal of third molars and block anesthesia. However, the most common cause is improper installation of dental implants in the area of ​​molars and premolars on lower and upper jaws. Mandibular canal damaging has several negative effects.

Loss of sensitivity on the lower jaw is one of the effects caused by bleeding and nerve compression. Such effect may disappear after several weeks. However, loss of sensitivity caused by nerve damages has permanent effect.

If case you inferior alveolar nerve damaging you should consider such issues as:

– Necessity to remove implant

– List of medications for your patient

– Opportunity to use electrical stimulation

– Dynamics of sensory loss

– Inferior alveolar nerve transposition

1. If loss of sensitivity is caused by hematoma, you can reduce the pressure on the tissue by dental implant extraction.

2. In cases of inferior alveolar nerve damaging, prescribe to your patients a complex of B6 and B12 vitamins

3. Using of electro stimulation is a very comprehensive question. However, there is a possibility of partial sensitivity restoration with this technique.

4. Dynamics of sensitivity recovery is characterized by nerve fibers formation. Such fibers provide afferent neurotransmission to other nidus. According to the study, most patients with such injury said about partial sensitivity recovery.

5. In some cases, the transposition of inferior alveolar nerve can cause paresthesia. Despite the fact that this intervention was popular in the past times, now the majority of dentists avoid it. Before inferior alveolar nerve transposition, you are obliged to carry out block anesthesia to your patients. Therefore, they will understand all the consequences of such surgery.

In conclusion, it should be noticed that this damage has a negative impact not only on dental implantation result, but also can cause serious harm to your patient health. Remember about these risks at all stages of planning and conducting dental implantation.
