A research report titled Survival Rates of Dental Implants in Patients with and without a History of Periodontitis
provides the following demographic data: Of the 717 patients in the study, "50.3% of them were placed in females, 82.6% in individuals with high socio‐economic status, 64.9% in self‐payers, 14.5% in tobacco users and 9.9% in diabetics. None to mild periodontal destruction was noted in 66.7% of the patients, while moderate and severe was detected in 33.3%. Within a mean follow‐up time of 29.19 months, five implants were removed representing a 0.7% failure rate. The survival rate in the periodontitis and non‐periodontitis groups showed no statistically significant differences (P = 0.837)."
Survey results from the American Association of Oral and Maxillofacial Surgeons found that: over 30 million people do not have teeth in one or both jaws, 26.0% people aged above 75 years do not have teeth at all, 69.0% of people aged between 35 and 45 years have one tooth missing, more than 15 million people have crowns or bridges, approximately 500,000 people undergo dental implant procedure each year, and dental implants have a success rate of about 95.0%.
