The power of Teeth in a Day is that it is an affordable, quick and effective way of getting your smile back. You look and feel like you have real teeth again. In the Teeth in a Day procedure, dentists use the All-on-4 procedure and/or the All-on-6 procedure to replace the teeth in both your jaws. It’s very common to use the All-on-4 procedure for the lower jaw and the All-on-6 procedure for the upper jaw. In principle, however, either procedure can be used for either jaw. Depending on which procedure(s) is/are used, the dentist will drill four or six holes into your jaw. These will be filled with dental implant screws and your overdenture will go on top. The dental implants will be permanent (or at least very long-term). For this reason, they will usually be made of titanium. Your initial overdenture will, however, almost certainly be temporary. Temporary overdentures are generally made of resin. This is not particularly durable. It is, however, very light and will have minimal impact on your jaw during the healing process. Your permanent overdenture will typically be made of zirconium with a porcelain veneer. Zirconium is for strength and porcelain for aesthetics.
