Dental implants have become the gold standard for replacing missing teeth, boasting clinical success rates exceeding 95%. However, achieving successful long-term osseointegration—the biological fusion of the titanium post with living jawbone—requires specific oral and systemic health conditions.
While many patients who were previously told they were not candidates can now receive implants through advanced regenerative procedures, certain absolute and relative contraindications must be evaluated during your consultation with Dr. Bryanna Hubbard at BB Dental Care in Burbank, CA.
Key Factors That Affect Dental Implant Eligibility
1. Active, Untreated Periodontal Disease
The same pathogenic bacteria responsible for periodontitis can infect the tissues surrounding a dental implant, causing peri-implantitis. If active gum infection is present, it must be completely resolved through deep cleaning (scaling and root planing) and periodontal maintenance before implant placement.
2. Antiresorptive & Bisphosphonate Therapy (MRONJ Risk)
Patients undergoing treatment with high-dose intravenous bisphosphonates or antiresorptive medications (such as Denosumab for osteoporosis or bone metastasis) face a rare but serious risk called Medication-Related Osteonecrosis of the Jaw (MRONJ). A thorough review of your medication history and consultation with your prescribing physician are essential before planning oral surgery.
3. Head and Neck Radiation Therapy
Radiation therapy to the jawbones compromises local micro-vascularity and reduces bone cellular activity, substantially elevating the risk of osteoradionecrosis and implant failure. A hyperbaric oxygen regimen or alternative restorative solutions (such as fixed bridges or partial dentures) may be indicated.
4. Uncontrolled Systemic Diseases
Uncontrolled Type 2 diabetes impairs peripheral circulation and immune function, delaying osseointegration and increasing vulnerability to post-surgical infection. When diabetes is well-managed (HbA1c levels stabilized), implant success rates approach those of healthy individuals.
5. Severe Bruxism (Chronic Teeth Grinding)
Patients who clench or grind their teeth with heavy occlusal forces risk overloading the implant post and fracturing ceramic crowns. While bruxism does not automatically disqualify you, it requires protective measures such as a custom laboratory-fabricated nightguard.
6. Heavy Smoking and Nicotine Use
Nicotine constricts peripheral blood vessels in mucosal tissue, impairing initial surgical wound healing and tripling the rate of implant failure. Patients are strongly advised to cease smoking several weeks before and after surgery.
What If You Have Low Jawbone Density? (The Good News)
Historically, patients with diminished jawbone height from long-standing tooth loss were deemed ineligible for implants. Today, modern bone augmentation procedures routinely solve this:
- Guided Bone Regeneration (Bone Grafting): Placing specialized bone graft material at the site stimulates new, dense bone growth over several months.
- Sinus Lift (Sinus Augmentation): For missing upper molars near the maxillary sinus, gently elevating the sinus membrane and placing graft material creates ample vertical height for sturdy implant posts.
