Whenever it is clinically acceptable to do so, patients needing more than one implant will receive both the EZ Plus implant and the AnyRidge implant, thereby serving as internal controls. Implants may be placed adjacent to one another and/or adjacent to remaining natural teeth. No sites will receive any type of implant-supported provisional restoration. All implants will receive a short healing abutment that protrudes through the gingiva but remains out of occlusion.
