Hemisection

Indhold

What is Hemisection?

A hemisection is a specialized dental procedure used as a last resort to preserve part of a tooth that would otherwise need to be fully removed. During a hemisection, a damaged or diseased root and its corresponding portion of the tooth’s crown are removed, while the remaining part of the tooth is left intact and functional. This technique is typically performed on multi-rooted teeth, such as molars, where it is possible to save a healthy root and its associated structure.


When is hemisection necessary?

Hemisection is not a routine dental treatment and is only performed under specific circumstances. Below are some situations where a hemisection may be considered:

  • Severe decay or root damage: If one root has been extensively damaged by decay or trauma and cannot be treated, a hemisection may be used to remove the diseased root while preserving the healthy part of the tooth.
  • Periodontal disease: In cases of advanced gum disease (periodontitis) where one root has become unstable or compromised, a hemisection can preserve the healthy portion of the tooth.
  • Root fracture: If only one root of a multi-rooted tooth is broken or damaged, the fractured root can be removed through a hemisection, retaining the rest of the tooth.

Advantages of hemisection

Hemisection offers several benefits compared to the complete removal of a tooth. Some of the key advantages are:

  • Retains tooth functionality: By only removing the affected part of the tooth, the patient can continue to use the remaining portion for chewing and biting.
  • Avoids dental implants: Keeping part of the tooth intact can, in some cases, eliminate the need for an implant or bridge, making it a more cost-effective option.
  • Prevents tooth shifting: When a tooth is fully extracted, neighboring teeth may shift into the empty space. Hemisection helps maintain the tooth’s position and alignment within the dental arch.
  • Shorter healing time: Compared to full tooth removal followed by implant surgery, hemisection typically involves a quicker recovery period.

How is a hemisection performed?

A hemisection requires expertise and is usually conducted by an experienced dentist or specialist. The procedure generally involves the following steps:

  1. X-ray examination: Before the procedure, the dentist performs a thorough examination using X-rays to assess the tooth’s structure and roots.
  2. Anesthesia: The area is numbed with local anesthesia to ensure a pain-free procedure.
  3. Removal of the diseased part: The damaged root and the corresponding portion of the crown are carefully removed.
  4. Restoration: After the root is removed, the remaining part of the tooth is reconstructed to restore its stability and function. This may involve placing a crown or another type of dental restoration.

What to expect after a hemisection?

Post-procedure care is crucial to achieve optimal healing and long-term success for the treated tooth. Below are some general guidelines to follow after a hemisection:

  • Pain relief: Mild discomfort is normal after the procedure and can usually be managed with over-the-counter pain relievers.
  • Good oral hygiene: Be diligent about brushing and flossing gently around the treated area to prevent infection.
  • Follow-up visits: Regular check-ups with your dentist will ensure that healing progresses as expected and that the remaining tooth stays healthy.

Is hemisection a permanent solution?

While hemisection can be an effective way to preserve a tooth, it is not always a permanent solution. The remaining part of the tooth will still require proper care and monitoring to stay healthy. Factors such as maintaining good oral hygiene and attending regular dental visits play a vital role in the longevity of the tooth after the procedure.
