Hemisection

Hemisection is a dental procedure in which one half of a tooth is surgically removed, typically due to significant damage or infection in one root or portion of the tooth. It is usually performed on multi-rooted teeth, such as molars, and aims to preserve the remaining healthy portion of the tooth while eliminating the diseased or compromised part.

Here's a detailed explanation of the hemisection procedure:

1. Indications:

• Hemisection is indicated when one root or portion of a multi-rooted tooth is extensively damaged or infected, making it non-restorable through conventional means like fillings or root canal therapy.
• Common reasons for hemisection include advanced periodontal disease, root fractures, extensive decay, or trauma to one root of a multi-rooted tooth.

1. Preparation:

• Before the procedure, the dentist will conduct a thorough examination of the affected tooth, including clinical assessment and radiographic evaluation, to determine the extent of damage and plan the treatment.
• Local anesthesia is administered to ensure the patient's comfort during the procedure.

1. Procedure:

• Tooth isolation: The tooth and surrounding area are isolated using a dental dam or other protective barrier to maintain a clean and sterile environment.
• Tooth sectioning: Using precise dental instruments, the dentist carefully divides the tooth along the furcation (the area where the roots meet) to separate the healthy portion from the diseased or damaged portion.
• Root removal: The affected root or portion of the tooth is surgically removed, along with any associated infection, debris, or damaged tissue. The remaining healthy root(s) and surrounding bone are preserved.
• Root canal therapy: If the remaining root(s) require root canal treatment, it may be performed to remove any remaining infected or inflamed tissue and seal the root canal space.
• Restoration: After root removal and root canal therapy (if needed), the remaining portion of the tooth is restored with a filling material or crown to restore function and aesthetics.

1. Postoperative Care:

• Following the procedure, the patient may experience some discomfort or swelling, which can be managed with pain medication and cold compresses applied to the outside of the cheek.
• Patients are advised to follow postoperative instructions provided by the dentist, including dietary restrictions, oral hygiene practices, and any prescribed medications.
• Regular follow-up appointments are scheduled to monitor healing, assess the stability of the remaining tooth structure, and address any concerns or complications.

1. Prognosis:

• The success of hemisection depends on various factors, including the extent of damage or infection, the patient's oral hygiene, and compliance with postoperative care instructions.
• With proper care and maintenance, a tooth that has undergone hemisection can continue to function effectively for many years, providing chewing function and aesthetics similar to a natural tooth.

In summary, hemisection is a dental procedure performed to remove one half of a tooth, typically due to significant damage or infection in one root or portion of the tooth. It aims to preserve the remaining healthy portion of the tooth while eliminating the diseased or compromised part, allowing for continued function and stability. If you have a tooth that may require hemisection or if you have any questions about the procedure, it's important to consult with your dentist for a thorough evaluation and personalized treatment plan.

Implant-supported Dentures

Implant-supported dentures are a type of dental restoration used to replace multiple missing teeth, typically an entire dental arch (either upper or lower), by anchoring the denture to dental implants. Unlike traditional dentures that rely solely on suction or adhesives for stability, implant-supported dentures are securely attached to dental implants embedded in the jawbone, providing increased stability, comfort, and chewing efficiency. Here's an overview of the process involved in placing implant-supported dentures:

1. Evaluation and Treatment Planning:

• Before undergoing implant treatment, the patient will undergo a comprehensive dental examination, including clinical assessment and radiographic evaluation (such as dental X-rays or CBCT scans).
• The dentist or oral surgeon will assess the patient's oral health, bone density, and suitability for implant placement.
• A thorough treatment plan will be developed based on the patient's individual needs and goals.

1. Implant Placement:

• The first step in the process involves surgically placing dental implants into the jawbone at strategic locations to support the denture.
• The number of implants needed depends on factors such as the size and shape of the jawbone, the stability of the implants, and the overall treatment plan.
• Implant placement is typically performed under local anesthesia to ensure the patient's comfort during the procedure.

1. Healing and Osseointegration:

• After implant placement, a healing period of several months is usually required to allow for osseointegration to occur.
• During this time, the implants fuse with the surrounding bone tissue, becoming firmly anchored in the jawbone.
• Temporary restorations may be placed during the healing period to maintain aesthetics and function.

1. Abutment Placement:

• Once osseointegration is complete, abutments are attached to the implants.
• Abutments are connector pieces that protrude from the gumline and serve as the attachment points for the implant-supported denture.

1. Impressions and Fabrication of Denture:

• After the abutments are placed, impressions of the implant sites and surrounding tissues are taken to create a custom-made denture.
• The denture is fabricated in a dental laboratory using durable and lifelike materials that mimic the appearance and function of natural teeth.
• The denture is designed to fit securely over the abutments and provide optimal support and stability.

1. Final Restoration:

• Once the denture is completed, it is attached to the abutments and secured in place using dental screws or other retention mechanisms.
• The denture is adjusted and polished to ensure proper fit, function, and aesthetics.
• The patient's bite and occlusion are checked to ensure comfort and stability.

1. Postoperative Care and Maintenance:

• After the implant-supported denture is placed, the patient will receive instructions on postoperative care and maintenance.
• Regular dental check-ups and professional cleanings are essential to monitor the health of the implants and surrounding tissues.
• Good oral hygiene practices, including brushing, flossing, and using antimicrobial mouthwash, are important for long-term success.

Implant-supported dentures offer numerous benefits, including improved stability, comfort, and chewing efficiency compared to traditional dentures. With proper care and maintenance, an implant-supported denture can provide long-lasting and natural-looking results, enhancing both oral health and quality of life. If you are considering implant treatment, it's important to consult with a qualified dental professional to determine the best treatment plan for your individual needs.
