98.2%
SUCCESS RATE
Dr. Eggleston’s tracked outcomes (2008–2011, 3,000+ implants) Most studies cite a 2–5% implant failure rate. Even patients with risk factors typically see success rates of 88–95% — still a strong outcome. This page helps you understand what may affect your individual risk.
The factors below are directly associated with a higher rate of implant failure within 5 years. Risk multipliers shown are based on published studies. Patients with more than one risk factor may face compounded risk.
2.7x
higher risk
Diabetes
Patients with poorly controlled diabetes have a 2.7× greater risk of dental implant failure. Elevated blood sugar levels can slow healing, reduce the body's ability to fight infection, and interfere with the bone's ability to successfully integrate with the implant. Maintaining good glycemic control before and after implant surgery can significantly improve treatment outcomes.
2.7x
higher risk
Head and Neck Radiation
Prior radiation therapy to the head and neck carries a 2.7× greater risk of failure, as radiation damages bone vascularity and the body's ability to integrate the implant.
2.5x
higher risk
Hormone Replacement Therapy
Women undergoing hormone replacement therapy have shown a 2.5× greater risk of implant failure in some studies, likely related to effects on bone remodeling.
2.2x
higher risk
Age Over 60
Patients over 60 have a 2.2× greater risk of implant failure compared to those aged 40–59, related to slower bone healing and reduced bone density.
Elevated risk
Corticosteroids
Prednisone, Prednisolone, and Dexamethasone are used for rheumatoid arthritis, asthma, and inflammatory bowel disease. They reduce the body's ability to absorb calcium and accelerate bone resorption — both harmful to implant integration.
Elevated risk
Smoking
Contributes to poor metabolism, impaired healing, and reduced blood flow to bone. Also associated with earlier onset of menopause in women, increasing bone loss risk sooner.
Elevated risk
High Alcohol Intake
Limits the stomach's ability to produce hydrochloric acid needed for calcium and magnesium absorption. When magnesium is lost in urine, it takes calcium with it — weakening the bone environment around the implant.
The factors below are associated with general bone density loss (osteoporosis). While they don’t directly cause implant failure, they may combine with the direct risk factors above to further increase overall risk. Do not stop any medication without consulting your physician.
- Medications Assiciated with Bone Loss
Anticoagulants
Warfarin (Coumadin), Heparin
Reduce the effects of vitamin K, which helps calcium bind to bone tissue. Used for heart disease, blood clot prevention, and post-surgical recovery.
Anticonvulsants
Carbamazepine (Tegretol), Pregabalin (Lyrica)
Interfere with vitamin D metabolism, reducing the body’s ability to absorb calcium. Used for epilepsy, bipolar disorder, fibromyalgia, and nerve pain.
Anti-Anxiety Medications
Clonazepam (Klonopin), Diazepam (Valium), Lorazepam (Ativan)
Inhibit vitamin D metabolism, leading to reduced calcium absorption and gradual bone loss.
Aromatase Inhibitors
Used in breast and ovarian cancer treatment
Disrupt estrogen production as part of cancer treatment, leading to accelerated bone loss as a side effect in post-menopausal women.
Diuretics
Furosemide (Lasix)
Cause the kidneys to excrete more calcium, contributing to bone loss over time. Prescribed for high blood pressure, heart failure, and kidney or liver disease.
Immunosuppressants
Used after organ transplant; also for psoriasis, Crohn's disease
Hinder the formation of new bone while suppressing immune reactions to prevent rejection or treat autoimmune conditions.
Kidney Dialysis Solutions & Antacids
Prilosec, Prevacid, Nexium
Contain aluminum or reduce stomach acid, disrupting the calcium-phosphorus balance needed for bone formation and interfering with calcium absorption.
Oral Contraceptives
Birth control pills
May elevate sex hormone binding globulin (SHBG) levels — an effect that can persist after stopping the pill — potentially impairing androgen activity and contributing to osteoporosis.
Lack of Exercise
Sedentary lifestyle
Lack of weight-bearing exercise accelerates bone loss. “Use it or lose it” applies directly to bone health — regular physical activity is one of the most effective tools for preserving bone density.
