How to Treat an Infected Dental Implant?

Published in Dental Implant Treatment 5 mins read

Treating an infected dental implant typically involves a multi-faceted approach aimed at controlling the infection, promoting healing, and preserving the implant whenever possible. Effective treatment strategies range from non-surgical methods to more invasive procedures, depending on the severity and stage of the infection.

Understanding Dental Implant Infection (Peri-implantitis)

Dental implant infection, often referred to as peri-implantitis, is a serious inflammatory condition affecting the tissues around a dental implant, leading to progressive bone loss. If left untreated, it can compromise the stability of the implant and ultimately lead to its failure. Early detection and prompt treatment are crucial for successful outcomes.

Key Treatment Approaches for Infected Dental Implants

Treatment protocols for an infected dental implant are tailored to the individual case, considering factors like the extent of bone loss, the type of bacteria involved, and the patient's overall health. Here's a breakdown of common treatment options:

Treatment Method Description
Antibiotics Targets and eliminates bacteria causing the infection. Administered orally or locally.
Mechanical Cleaning Non-surgical removal of plaque, calculus, and granulation tissue from the implant surface and surrounding area.
Surgery Surgical procedures to access and thoroughly clean the infected area, regenerate lost bone, or correct contributing anatomical factors.
Implant Removal The last resort when other treatments have failed, or the infection is too severe, involving the extraction of the compromised implant.

1. Antibiotics

Antibiotics: Just as antibiotics prevent other infections, they can kill and stop bacteria from growing and spreading around an implant.

Antibiotics are a cornerstone of treatment for bacterial infections associated with dental implants. They can be prescribed in various forms:

  • Systemic Antibiotics: Taken orally, these medications work throughout the body to combat the bacterial infection. Common choices include amoxicillin, metronidazole, or a combination. Your dentist will determine the appropriate type and dosage based on the suspected bacteria and severity of the infection.
  • Local Antibiotics: These are applied directly to the infected area, often in the form of gels or controlled-release devices inserted into the peri-implant pocket. This delivers a high concentration of medication precisely where it's needed, minimizing systemic side effects.

Antibiotics are often used in conjunction with other treatments, especially mechanical cleaning, to enhance effectiveness.

2. Mechanical Cleaning

Mechanical cleaning is a crucial non-surgical approach to decontaminate the surface of an infected dental implant and the surrounding tissues. This procedure aims to reduce the bacterial load and remove inflammatory tissue. It typically involves:

  • Debridement: Careful removal of plaque, calculus, and infected granulation tissue from the implant surface and pocket using specialized instruments.
  • Scaling and Polishing: Utilizing plastic, titanium, or carbon fiber instruments (rather than traditional metal scalers which can scratch the implant surface) to clean the implant thoroughly.
  • Antiseptic Rinses: Adjunctive use of antimicrobial mouthrinses (e.g., chlorhexidine) can further reduce bacteria and support healing.

This step is vital for creating a cleaner environment that supports tissue healing and reduces inflammation.

3. Surgery

When non-surgical treatments are insufficient, surgical intervention becomes necessary to effectively treat advanced peri-implantitis. Surgical procedures aim to thoroughly decontaminate the implant surface, regenerate lost bone, or recontour surrounding tissues. Common surgical approaches include:

  • Access Flap Surgery: Involves lifting the gum tissue (a flap) to gain direct visual access to the infected implant surface and underlying bone. This allows for thorough cleaning and debridement.
  • Osseous Recontouring (Osteoplasty/Ostectomy): Reshaping or removing compromised bone around the implant to create a more favorable contour that reduces pockets and facilitates better hygiene.
  • Guided Bone Regeneration (GBR): Techniques used to reconstruct bone lost due to infection. This often involves placing bone graft materials (autogenous, allograft, xenograft, or alloplast) and covering them with a barrier membrane to encourage new bone formation around the implant.
  • Laser Therapy: Specific dental lasers can be used to decontaminate the implant surface and remove diseased tissue, offering a less invasive alternative in some cases.

The goal of surgery is to halt disease progression, regenerate lost support, and improve the long-term prognosis of the implant.

4. Implant Removal

Implant removal is considered a last resort when the infection is severe, irreversible bone loss has occurred, or other treatment modalities have failed to resolve the peri-implantitis. This decision is made when the implant is beyond salvageable repair and poses a risk to the patient's oral health.

Reasons for implant removal include:

  • Extensive, irreversible bone loss around the implant.
  • Persistent infection despite multiple treatment attempts.
  • Severe mobility of the implant.
  • Compromise to adjacent teeth or anatomical structures.

After implant removal, a period of healing is required, after which further restorative options, such as a new implant in a different location, a bridge, or a removable prosthesis, can be considered.

Importance of Early Detection and Prevention

Preventing dental implant infection begins with meticulous oral hygiene at home, regular dental check-ups, and professional cleanings. Early signs like redness, swelling, bleeding, or pus around the implant should prompt immediate dental consultation. Prompt diagnosis and treatment significantly improve the chances of saving an infected implant.
