Tuberpterygoid implants are implants which found the upper jaw zone. In the upper jaw, they let the prosthetic restoration on dental inserts. For quick stacking of the inserts, the connected strengths go to pterygomaxillar support region for permitting.

Tuberopterygoid 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 pterygomaxillary buttress area allowing immediate loading of the implants. The white arrows show tuberopterygoid implant, this avoided invasive Sinus lift Surgery and saved time period of 6-8 months post sinus lift surgery.We were in position to deliver fixed teeeth in period of just 3 days even in such an atrophied situation.
No More Sinus Lift
No More Bone graft.
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. Tubero pterygoid implants are 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 anesthesia.
Throughout literature, several terms are being used to describe pterygoid implants. The terms "pterygoid implants", "pterygomaxillary implants" and "tuberosity implants" are used interchangeably. "Pterygoid implants" have been defined by the Glossary of Oral and Maxillofacial Implants (GOMI) as "implant placement through the maxillary tuberosity and into the pterygoid plate".
There are significant differences between pterygoid and tuberosity implants including the following:
When the upper grinding teeth are lost and are not replaced on time, it leads to drooping of the sinus there by resulting in bone resorption making it difficult for tooth replacement, Some conventional implantologists suggest Sinus lift procedure, which is a complex traumatic surgical approach, that is totally unpredictable and takes approximately 6 to 8 months to heal.All the patients interested in getting the upper full arch replaced on implants are suitable candidates for this as pterygoid bone is present in all the patients. Pterygoid bone is present distal to the second molar region in the upper jaw and is the only option available if you want to avoid cantilevers, but it requires a very experienced hand with an in depth knowledge of Anatomy of the surrounding areas.
The pterygoid implant is placed in the region of the former first or second maxillary molars and follows a diagonal direction posteriorly towards the pyramidal process. The implant ultimately anchors in the pterygoid fossa of the sphenoid bone. The angulation of pterygoid implants ranges from 45°-50° towards the maxillary plane.
In clinical reality, whenever pterygoid implants are described those are in reality tuberosity implants with an anchorage in the pterygoid plate and thus the treatment difficulties are very limited. As with every implant surgery the preparation of the implant bed is of high importance and treatment planning should be performed with great attention to the anatomical structures and bone availability/quality.
Efficient chewing is possible as teeth upto second molars are replaced. In cantilevers and zygomatic implant cases or in single piece implants 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.
Single piece implants are used which are strong in comparison to conventional dental implants.
