I am planning on placing implants in the upper left posterior quadrant where 25 and 27 are missing and with 26 and 28 grossly decayed. I am planning for extraction of 26 and 28. What would be the best sites for implant placement? Should I place an implant in 25 and 27 region and then extract 26 and go for a 3-unit bridge? Is that a sound plan of treatment? What do you recommend?
