Restoring Function After RCT Failure: A Case of Dental Implant Rehabilitation

Patient's Age: 38 years
Concern: lower tooth fracture

Case duration: 2.5 months (implant placement – single day)

What Brought the Patient to Us?

The Patient was facing an issue with lower premolar teeth, upon examining we found that the tooth was previously treated (RCT). Now since the tooth has got re-infection and less crown structure left, we decided to replace the tooth with a much more predictable treatment option called dental implant.  

What Did We See?

During his dental check-up, we found:

      There was a fracture of the roots of the lower premolar teeth

      The teeth were previously RCT  treated.

      There were signs of infections beneath the tooth.

Step-by-Step Procedure

1. Initial Consultation

Evaluation: We examined the mouth, took X-rays, 3D scans, and impressions.

Medical History: Review of general health

Treatment Plan: Customized plan considering the number of teeth to replace, bone health, and type of implant.

2. Tooth Extraction 

Performed under local anaesthesia to ensure a pain free experience.

3. Implant Placement Surgery

Procedure:

Gum is opened to expose the bone.

A hole is drilled into the bone.

The titanium implant post is placed deep into the bone.

Healing time (Osseointegration): 2-3 months. The bone fuses with the implant.

4. Abutment Placement

After healing: A small connector called an abutment is attached to the implant.

Minor surgery: Often done under local anaesthesia. Sometimes this is done during the implant placement.

Gum healing: Takes about 1 to 2 weeks.

5. Crown (Artificial Tooth) Placement

Impressions OR digital intraoral scan of the gums are taken.

A custom dental crown is made to match your natural teeth.

The crown is attached to the abutment (can be cemented or screwed).

6. Follow-Up & Maintenance

Check-ups: Regular dental visits to ensure implant stability and oral health.

Oral hygiene: Brush, floss, and avoid hard foods to protect the implant.
