Good morning, @hilotpilot What’s the old axiom…A good deed never goes unpunished? You were so thoughtful trying to save your neighbor’s dog from harm but sure did a number on yourself! And I bet the dog was totally obvious as to what his rescue cost you personally. 😉

The fall had to be frightening after all you’ve gone through with your back surgeries! Especially with having all of the supporting metal removed because of infection! Was there a replacment treatment for you? Was the original surgery related to osteoporosis?

The fact that you did have a reaction to the titanium has me wondering about the potential for similar issues with dental implants because most are titanium or zirconium oxide. There are full ceramic implants which would lessen a change of allergic response.

With having Reclast injections or taking bisphosphonate bone loss therapy (antiresorptive drugs) there’s a rare risk for osteonecrois of the jaw with certain procedures such as extractions, oral surgery and dental implants. Osteonecrosis most often happens when something, such as a bone injury, interferes with blood supply to a bone, causing that area of the bone to die. It’s not a common event and from my understanding, if precautions such as being prescribed prophylactic antibiotics and Chlorhexidine antibacterial mouth rinse before dental treatments, can lessen the risk for infection. Since you mentioned being prone to infection this would be a must for you.

Another option to lessen the risk for infection and increase the success of the implant might be to stop the Reclast treatment for a couple of months prior to your dental procedure. Since you enjoy information like I do, I found an article for you about implants and ‘taking a holiday’ from the meds prior to treatment. Saved me from typing it all out! 😉

Being on bone loss drugs isn’t a barrier to having implants.
Your dentist and endodontist seem comfortable with your being able to go ahead with treatment. The root canal shouldn’t pose any risk. But they should take into consideration your reaction to titanium in making the decision about the implants. I’m not a dentist and can’t diagnose or offer treatment plans, however I can use my experience of 30+ years as a certified dental assistant to offer opinions. If this were me (with your negative titanium experience) and I went ahead with the implants, I’d opt for full ceramic implants…nothing titanium in my jaw. Generally the titanium implants are very safe and they are the mainstay of implantation.

There are also different risk levels for incident rate of osteonecrosis to the jaw and they’re related to dosage and duration. Example, people who have osteoporosis due to cancer treatments often receive higher dosages of the bone loss meds and they are also at higher risk for developing osteonecrosis. The risk diminishes greatly if someone is taking Reclast for less than 4 years.
Tossing in another great article on the use of ARONJ (antiresportive-drugs related osteonecrosis of the jaw)

Bottom line, if you trust the experience level of your two dental specialists, I’d go ahead with the treatment plan. You might talk to them about their opinion of ‘taking a holiday’ from the Reclast and, follow a prophylactic antibiotic program/medicated mouthrinse to lessen the infection risk.

If you didn’t have implants, was there another option/suggestion for tooth replacement?
