Tuberopterygoid Implants Vs Zygomatic implants
 |
| Tubero pterigiod screw |
 |
| Zygomatic screw |
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.

Zygomatic implants
| |
Type of implants
|
Single piece Implants is used
|
Screw based implants used
|
Screw loosening
|
No screw loosening and no crestal bone loss
|
Screw loosening is a problem

No cantilevers placed
|
Molars if given are placed as cantilevers, which decrease the life of the bridge and cause screw loosening on the implant.
|
Criteria
|
No contraindications
|
Symptom free and pathologically free sinus
|
Relative risk of failure
|
Since sinus is not involved, no risk of sinusitis
|
Risk of sinus infection
|

Thanks for taking the time to discuss that, I feel strongly about this and so really like getting to know more on this kind of field. Do you mind updating your blog post with additional insight? It should be really useful for all of us. Invisalign Kettering
