How is a coronectomy performed?

How is a coronectomy performed?

A coronectomy is also known as an intentional partial tooth extraction. It is a technique sensitive procedure best performed by your oral and maxillofacial specialists. The tooth is sectioned into upper and lower halves. The crown is removed in its entirety along with part of the roots.

Is coronectomy really preferable to extraction?

Coronectomy in that situation can be a safe procedure that’s associated with a low incidence of injury to the lingual or inferior alveolar nerves. According to other research from 2015 , a coronectomy is preferable to extraction for preventing neurological damage when roots are near the IAN.

What are the risks of coronectomy?

Coronectomy was associated with a low incidence of complications in terms of inferior alveolar nerve injury (0%-9.5%), lingual nerve injury (0%-2%), postoperative pain (1.1%-41.9%) and swelling (4.6%), dry socket infection (2%-12%), infection rate (1%-9.5%) and pulp disease (0.9%).

How long does it take to heal from a coronectomy?

Most of the time it is temporary, although it can take up to 18 months to recover. On occasions it may not fully recover and patients may be left with patches of numbness.

Can tooth roots wrapped around jaw?

The crown of a tooth is the tooth surface that you see in the mouth and the roots are the part in the bone. As the roots get larger, they can grow and wrap around the nerve inside the jaw. This nerve is called that inferior alveolar nerve and gives sensation to the lower lip, chin and cheek.

What happens if your wisdom tooth cracks?

Additionally, a broken or cracked wisdom tooth puts the entire tooth’s health at risk. Bacteria can invade the tooth and infect the dental pulp. In those cases, the tooth must either be extracted or given a root canal treatment. In most cases, it’s better just to remove the tooth.

What happens to roots after Coronectomy?

In most cases, the roots become encased in the lower jaw bone and never cause problems again. In some instances, the roots can become infected and may need to be extracted but this is only in a small number of cases. In some instances, after a coronectomy the remaining roots may migrate toward the oral cavity.

Can you get dry socket with Coronectomy?

Coronectomy patients also suffer from alveolar osteitis (dry socket) and treatment of these cases remains the same as for traditional extraction alveolar osteitis so long as the root is not mobile.

What happens after a Coronectomy?

Recovery from this procedure is very similar to having the entire tooth extracting. In most cases, the roots become encased in the lower jaw bone and never cause problems again. In some instances, the roots can become infected and may need to be extracted but this is only in a small number of cases.

Can a Coronectomy cause nerve damage?

Key Points. Coronectomy is a technique that should be considered for mandibular third molars when it is felt there is an increased risk of injury to the inferior dental nerve.

Is it bad to have long teeth roots?

The tooth root sits below the gumline and helps anchor the tooth in the jawbone. An exposed root can indicate damage to the gums or teeth. When a tooth root is no longer concealed by the gums, this can trigger sensitivity and pain. Without treatment, it may lead to infection and other complications.

Is coronectomy a viable technique for root canal?

Conclusion: Coronectomy appears to be a viable technique in those cases where removal of the whole tooth might put the inferior alveolar nerve at considerable risk of damage. The technique appears to be associated with a low incidence of complications, but subsequent migration of the roots may be an issue in the long term.

How is the lingual nerve protected during a coronectomy?

The technique of coronectomy deliberately protected the lingual nerve as part of the surgical procedure. All roots were left at least 3 mm below the buccal and lingual plates of bone.

What is coronectomy for lower third molars?

The technique of coronectomy, or intentional root retention, may minimize this problem. Patients and methods: Forty-one patients underwent coronectomy on 50 lower third molars with follow-up of at least 6 months. The technique of coronectomy deliberately protected the lingual nerve as part of the surgical procedure.

What are the possible complications of a coronectomy?

Root migration (30 per cent) 14. Post-operative pain is an expected complication but the more conservative nature of the coronectomy procedure results in less tissue disturbance and thus less post-operative pain than conventional surgical removal.
