I had full extractions,wth interim dentures, scheduled for implanted supported . Now I'm worried that this may become a problem with bone loss under the bridges. He plan is 3 bridges per arch 12 "teeth" per arch total, was hoping 14, cemented to implanted abutments. The dentist suggested 6 implants, and this doesn't seem enough to prevent bone loss, or support that length of bridges. Also, is cementing to implants the best plan, as opposed to screwed in? Any input would be appreciated!

Answer: Implants First of all, having more implants isn't what would prevent bone loss. The main issue is the amount of support necessary to provide you stable, long lasting teeth. Personally, if my patient will have 6 implants and we will make bridges, as opposed to screwing in a denture, the number of teeth we would make is 10. I don't make anything longer than a 3 tooth bridge in the back. It's different for a denture since the implants can be spread out more to accommodate the denture. Having 8 implants could give you 10 teeth. I also like to have 3 bridges in this scenario. It would be my preference to screw in the crowns(bridges), but sometimes, especially in the front, they need to be cemented due because of where the implants must be placed.

Answer: How many implants for implant supported bridges? Six implants per arch should be sufficient, provided there is enough bone support for each implant. The problem with 3 implant supported bridges is that each bridge will only be supported by 2 implants. If ever one implant fails, then you would require another implant and probably bone grafting plus a new bridge. A better alternative would be a screw retained bridge or hybrid denture supported by all 6 implants. You could get 14 teeth per arch depending on how far back the last implant could be placed. If you could afford 8 implants per arch and there is enough bone to place them, this would be better to support 14 teeth. Screw retained would be the better way to go as this allows the bridge to be removed to gain access to treat a failing implant or for a repair if necessary. One of the major causes of implant failure is pericementitis, caused by cement that has been inadvertently not cleaned thoroughly from around an implant. Screw retained bridges or hybrid dentures eliminate this problem as there is no cement.
