Dental implants are a durable solution for replacing missing teeth, offering function and appearance similar to natural teeth. The success of these titanium posts, which are surgically placed into the jawbone, depends entirely on the health of the surrounding oral tissues. Periodontal disease (gum disease) is a bacterial infection that damages the gums and underlying bone. Implants can be placed, but only after the active infection has been fully treated and gum health has been stabilized.
Why Active Gum Disease Makes Implants Risky
Active periodontal disease significantly compromises the initial success of a dental implant procedure. The fundamental goal is osseointegration, where the titanium post fuses directly with the jawbone over several months. Active gum disease introduces an overwhelming bacterial load into the surgical site, interfering with this healing process.
The bacteria responsible for periodontitis can colonize the implant surface, leading to early failure before integration occurs. Periodontal disease causes progressive bone resorption, destroying the jawbone needed for stable anchorage. A sufficient volume of healthy bone is necessary to secure the implant.
Furthermore, the inflammation associated with active gum disease compromises the body’s ability to heal efficiently following surgery. When tissues are inflamed, the cellular response needed for bone and gum regeneration is impaired. This environment increases the risk of the implant failing to integrate, making prior disease treatment mandatory.
Necessary Steps Before Implant Placement
Before a patient can be considered a suitable candidate for implants, the active infection must be brought under control to achieve periodontal stability. The first step is professional deep cleaning, known as scaling and root planing. This intensive procedure involves removing hardened bacterial deposits (calculus) from tooth surfaces and deep below the gum line.
Root planing smooths the root surfaces of remaining natural teeth, removing bacterial toxins and hindering new accumulation. This non-surgical therapy reduces inflammation and pocket depths. After initial therapy, a waiting period of several months is required to allow gums to heal and confirm the disease is no longer progressing.
If the disease caused extensive destruction, adjunctive procedures may be necessary to rebuild the site. Significant bone loss often requires bone grafting to restore the necessary height and width for implant stability. Soft tissue grafting may also be performed to replace lost gum tissue and create a robust seal around the future implant. Achieving a periodontally stable mouth is the fundamental prerequisite for long-term implant success.
The Specific Risk: Peri-Implantitis
Even after successful treatment of periodontitis and subsequent implant placement, a unique long-term complication known as peri-implantitis remains a concern. Peri-implantitis is an inflammatory condition affecting the soft tissues and bone surrounding a dental implant. It is the implant equivalent of periodontitis, caused by bacterial biofilm accumulation on the implant surface.
Patients with a history of periodontitis are more susceptible to developing peri-implantitis due to the persistence of specific bacterial strains that can colonize the implant site. Peri-implantitis begins as peri-implant mucositis, which is reversible inflammation of the gum tissue around the implant. If left untreated, the condition progresses, causing progressive loss of the bone supporting the implant.
Patients should monitor for signs like redness, swelling, tenderness, or bleeding around the implant. Advanced cases lead to pain, pus discharge, and ultimately, implant mobility, indicating failure.
Long-Term Care for Implant Success
Given the increased susceptibility to peri-implantitis, patients with a history of gum disease must commit to a significantly heightened maintenance regimen to protect their investment. This commitment involves both rigorous home care and frequent professional oversight. At home, meticulous plaque control is paramount, often requiring specialized tools that can clean the unique surfaces and contours of an implant and its restoration.
Daily routines should include the use of specialized interdental brushes, implant-specific floss, and often a water flosser, which helps disrupt the bacterial biofilm. Proper hygiene is non-negotiable for these patients, as poor plaque control is one of the primary risk factors for developing peri-implant disease.
The second half of the maintenance program involves professional supportive therapy, which is typically scheduled more frequently than the standard six-month interval. For individuals with a history of periodontitis, a three-month recall interval for professional cleaning and examination is often recommended. These appointments allow the dental team to assess the health of the tissues, measure bone levels through X-rays, and remove any hardened deposits that a patient cannot reach. This proactive and frequent professional care is a determining factor in ensuring the long-term survival and stability of the dental implants.
