Why some dental implants work and others don’t

Each year, about 500,000 North Americans get dental implants.

If you are one of them, and are preparing to have an implant, it might be a good idea to start taking beta blockers, medication that controls high blood pressure, for a while.

And to stop taking heartburn pills.

A body of research from McGill led-teams indicates that in order to raise the odds that dental implants will attach properly, there are clear benefits to taking certain common medications and avoiding others.

The McGill research team reviewed data about the integration of dental implants gathered from over 700 patients who were operated on at the East Coast Oral Surgery Clinic in Moncton, New Brunswick between 2007-2015.

They then confirmed the results they saw in human patients through studies in rats.

Drugs that aid integration of implants — Beta blockers

  • Conclusions are based on 1499 dental implants in 728 patients between Jan. 2007 — Sept. 2013 at the East Coast Oral Surgery in Moncton, New Brunswick
  • 327 implants were in 142 people who took beta blockers for hypertension
  • 1172 implants were in 586 people who didn’t take beta blockers
  • Failure rates of implants for people using beta blockers was 0.6%
  • Failure rates of implants in people who don’t take beta blockers was 4.1%
  • More than 640 million patients around the world take beta blockers to control hypertension.

Drugs that impede integration of dental implants — Heartburn treatment

  • Conclusions are based on 1773 dental implants in 799 patients between Jan. 2007 — Sept. 2015 at the East Coast Oral Surgery in Moncton, New Brunswick
  • 133 implants were in 58 people who took heartburn medication
  • 1640 implants were in 741 people who don’t take heartburn medication
  • Failure rates of implants for people using heartburn medication were 6.8%
  • Failure rates of implants for people not taking heartburn medication were 3.2%
  • More than 20 million Americans, about one in 14 people, take heartburn medication.
  • Heartburn medication is rapidly becoming the third most prescribed pharmaceutical product worldwide, especially for elderly people, who take it either on an occasional or long-term basis.
