How Does It Work?

The implants provide complete support for the teeth and require no support from the gum tissue as in the case for removable complete set of teeth. Therefore, the prosthesis design has no flanges extending into the cheeks or palate, making it most comfortable and natural to the patient. The implants support a framework, either made of Titanium or Zirconia, which in-turn supports the teeth made of either of acrylic, porcelain, or zirconia. The teeth are held to the implants with retaining screws and hence it is fixed and not removable by the patient. Depending on the patient’s bite requirements four to eight dental implants may be recommended best judged by the condition of your oral cavity.

Treatment Stages and Process

The treatment is highly specialized therefore strongly recommended to visit an experienced Prosthodontist and Implantologist. The treatment sequence is:

  1. The Prosthodontist completes clinical evaluation of your mouth, including the condition jaw bone and if required takes impressions for study models and design, as well as assess the bite and aesthetic requirements. An interim denture is then fabricated and tried in the patient for proper fit and assure patient is happy with its aesthetics and design.
  2. Then an specialized 3D x-ray of the jaw required to be done (CBCT- cone beam CT) to assess quality and quantity of bone and to fabricate the final treatment planning that includes the number of implant required.
  3. The Prosthodontist then uses the CBCT for a 3-dimensional computer assisted planning in the computer model of patient’s jaw bone.
  4. The Prosthodontist places the dental implants according to the available jaw bone and requirement of fixed teeth at strategic location with optimal precision and accuracy. The implants are allowed to heal for 3-4 months before fabrication of the final teeth.
  5. Another alternative is the implants are immediately restored with a temporary fixed set of teeth (known as Teeth-In-A-Day). In this case, patient goes home with fixed teeth. The implants are allowed to heal for 3-4 months before fabrication of the final teeth.
  6. When immediate implant restoration is not possible or recommended, then the implants are allowed to heal for 3-4 months before final teeth are made. Patient continues using the transitional denture in the interim.
  7. The expertise Prosthodontist then takes final impressions and fabricates the final fixed prosthesis. The bite is adjusted as it was in natural teeth and the new teeth are checked for overall comfort, function, and aesthetics.
