“Size of the Jaws and Teeth: Since implants are generally placed only in adult humans over the age of 20 years, the average size of the teeth and jaws in humans is reasonably consistent. Human tooth roots range in diameter from 3.0 mm in lower incisors to 7.0 mm in molar teeth. Human teeth roots range in length from 10.0 mm to 20.0 mm and are consistently conical in shape. This narrow range of diameters, lengths and shape in turn allows the manufacturers to limit the sizes and shapes offered.
