Zygomatic Dental 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 upper jaw is pterygoid implant. Pterygoid implants are replacing zygomatic implants as the best solution for patients requiring dental implants for upper jaw. Such patients were going for sinus lift or bone grafts as per old techniques. In a single procedure we place pterygoid implant and place the permanent crown in 3 days. As we use single piece implants the procedure is flapless and done under local anaesthesia.
|Type of implants||Single piece Implants is
used. No screw loosening and no crestal bone loss.
|Screw based implants used.
Screw loosening is a problem
|Cantilevers||No cantilevers placed||Molars if given are placed as
cantilevers, which decrease the life of the bridge and cause
screw loosening on the implant.

When the patient requires fixed teeth on dental implants in upper jaw, then the options are:
Cantilever bridges: For example in All-on-4 or All-on-6 techniques, implants are placed in anterior regions only and 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.

What are Tuberopterygoid implants
Pterygoid implants are implants located in 2nd molar area of upper jaw. They allow the prosthetic rehabilitation on dental implants in 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 upto second molars are replaced. In cantilevers and zygomatic implant cases or in all-on -4 and all – on – 6 techniques 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 permanent crown in 3 days.
» Single piece implants are used which are strong in comparision 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.
