If i have had two graft failures in preparation for a tooth implant on #9 should i try for a third? i'm 69, non smoker, good health and good teeth. would using my own bone help?

Some thoughts: If two attempts failed, why would a third work? Was it done by a periodontist or an oral surgeon? Is your dentist suggesting a third procedure? Or was that your idea? What are your alternatives (such as a fixed bridge)? What would make a third attempt successful? This requires a serious discussion with your dentist. Consider a second expert opinion. Also discuss with restorative dds.

See below: What caused the failures? I would not do a third until i got some answers your health might not be as good as you think unless the reason for the grafts failing was mechanical, i would have a nutritional workup done before i did anything else.

Second opinion: There are implantologist/oral surgeons that see failed graft implant patients on a regular basis . Your case sounds complex since your results are not the norm. Being older, there are many factors that can influence outcome le. Taking certain drugs like biphosphonates, or diabetis, lupus or other systemic conditions that make this graft challanging.

Questions: Your questions raises more questions? What material was used the first time? Is this procedure with the same surgeon? Have you explored other options? How did the first two fail? Your own bone is the gold standard.

Second opinion: Get an appt w a periodontist for a second opinion!

Possibly: As mentioned by other docs, the question here is 'why did the graft fail?' what is the experience of the surgeon? What material was used? These can all lead to some clarification. Using your own bone could very well help. I recommend you see a diplomate of the american board of oral implantology for a 2nd opinion. www.aboi.org.
