Mini implants vs conventional dental implants
Mini implants can certainly improve your condition, but they are not designed for long-term and have higher complications in relation to conventional dental implants. There are usually adequate space for placement of conventional implants. For diagnostics, you dentists should take a cone beam CT scan of your jaw and then one off your existing denture, if you have one. Then using 3-D planning software, perform virtual implant placement and see what the possibilities are.
Mini implants are not for this
minim plants are just for snap indentures, not for bridges, so place regular implants, and you will have a great solution.
