Several factors need to be taken into consideration to determine what is your best option. First and foremost, your health status needs to be addressed. Next, the amount of bone and density needs to be evaluated with a cone beam CT machine. Pre-operative cone beam CT evaluation is best way to determine how much bone you have and the density. This is extremely important. It also allows 3D evaluation so that the doctor can look at how your jaw is shaped. Knowing how your jaw is shaped helps prevent common complications associated with implant placement. Given your health status is acceptable and you have adequate bone volume, standard diameter implants to support your prosthesis will have less potential for future problems and provide excellent stability. It is a common misconception that mini-implants don't require surgery to place. It is true that mini-implants and standard diameter implants can be placed without a surgical flap (Flapless). Both techniques whether a mini-implant or standard diameter, should be guided by a CBCT to avoid potential pitfalls associated with flapless surgery.
