Zygomatic Implants

If you have been told that there is less bone in your upper jaw for dental implants, do not worry. The best solution for cases with severe bone resorption in the upper jaw is a pterygoid implant. Pterygoid implants are replacing zygomatic implants as the best solution for patients requiring dental implants for the upper jaw. Such patients were going for sinus lift or bone grafts as per old techniques. In a single procedure, we place a pterygoid implant and place the permanent crown in 3 days. As we use single piece implants the procedure is flapless and done under local anesthesia.

Zygomatic Implants Vs. Tuberopterygoid Implants

When the patient requires fixed teeth on dental implants in upper jaw, then the options are:

Cantilever bridges:

Techniques have been devised to avoid the expensive and aggressive bone grafting by placing just 4 or 6 implants in the front part of the jaw and placing a set of just 10 or 12 teeth. As such 1st molar crowns are placed as cantilevers and 2nd molars are not replaced at all. Sometimes only 10 teeth are placed. Another disadvantage of cantilevers is that the permanent ceramic bridges are fixed after 3-6 months.

Sinus Lift:
Implants in anatomic buttress areas:
  • Zygomatic implants
  • Tubero-pterygoid implants

What are Tuberopterygoid implants

Pterygoid implants are implants located in the 2nd molar area of the upper jaw. They allow the prosthetic rehabilitation on dental implants in the upper jaw. The applied forces go to the pterygomaxillar buttress area allowing immediate loading of the implants.

Advantages of pterygoid implants

  • Eliminates the need of sinus grafting.
  • No cantilevers from front teeth or implants.
  • Efficient chewing is possible as teeth up to second molars are replaced. In cantilevers and zygomatic implant cases 2nd molars are not replaced. If replaced then they are made as cantilevers which make the last implant weak and the bridge susceptible to fracture in the long run.
  • Bone in pterygoid area is cortical in nature, and hence very strong and rigid allowing Immediate loading with a permanent crown in 3 days.
  • Single piece implants are used which are strong in comparison to conventional dental implants.
  • All patients who want dental implants in upper jaw are good candidates as bone is always available in pterygoid area.
  • Flapless technique is used, as such patients have no swelling or bleeding and patients need not stop blood thinners, if they are taking any.
  • Lifetime warranty given as strong single piece implants are being used in strong cortical bone.
  • 100% success rate.
