Digital oral implants scan the alveolar bone position where the teeth are missing, construct a three-dimensional image of the area around the alveolar bone, and then determine the implant position. During the specific implantation, an alveolar bone drill is used to drill a hole in the alveolar bone, and then the bolt seat is installed in the hole. When drilling, the drill bit is required to be completely perpendicular to the drilling position, and the drill bit must be kept vertical during the movement.
