I recently had a block graft in the maxilla and #7,10 extracted, sockets grafted. I would like to get 4 implants and 4 unsplinted crowns, for easy maintenance/flossing around implants.
CT scan in simplant format shows 23mm space between maxillary canines. I also measured with a ruler and it's the same 23mm. Is 23mm enough space to place 4 implants to replace 7,8,9,10, to get predictable results and long term stability, for papilla to grow? Aesthetics is not an issue, my smile is narrow.
Or, should i go with 2 large implants and a 4-unit bridge? Maintenance is my only concern, don't like to use proxabrushes and threaders.
