Teeth ON THE SAME DAY with ALL-ON-4®
Teeth on the same day is a merging of both old and new techniques. For nearly a century, dentists have pre-made dentures for patients so that on the day of the surgical removal of the teeth they would be given their new teeth (dentures). This technique was referred to as “Immediate Dentures.” Now, with the advent of dental implants, we are able to perform the same process while also connecting the dentures to the implants. In the implant community this concept was revolutionary because early implant technique dictated waiting six months before using (loading) the implants. This left the patients feeling uncomfortable and embarrassed for an extended period of time.
Now we are merging the two because of a technique known as splinting. This is where all the implants are connected together via the immediate denture. By splinting them together, the load on the implants is distributed in such a way that they are healing is not impaired. This is technique comes under many names, each attributed to the people who made various improvements on the process (Teeth In A Day, All-On-Four®, etc.).
This merging of knowledge and experience achieves not only increased safety, but also a more precise implant placement. In addition, the fabrication of a final prosthesis is completed prior to the surgery. The computer-guided implant surgery is done in an arthroscopic fashion without requiring any flap reflection. This benefits the patient in that there is less postoperative discomfort, less swelling, and less bruising. Patients can often resume their normal activities the next day.
The process begins when a CAT scan is taken of the patient’s jaw bone. This CAT scan allows for the generation of a three-dimensional model of the jaw bone that can then be used with virtual reality software to plan the implant placement without the presence of the patient. The results are a more accurate implant placement and less chair time for the patient.
