Can only do two implants on one side of my mouth - is it even worth it?

it is very unlikely that you can only do two implants to secure a denture, angled implants around the nerve/sinus are almost always an option on the top or bottom

Hello. First of all, a 3-D CT analysis is very imporant to evaluate current situation. Two implants for overdenture prosthesis is the simplest and cost effective way of treatment but a fixed implant supported solution such as an all-on-4 may be more effective in terms of chewing ability and resistance.
