When are Pterygoid Impants Used?

​

When treating an edentulous upper jaw, implant placement can be a challenge given the limited amount of bone mass and the presence of the maxillary sinus. Dr Zdenko Trampuš was the first in Croatia to introduce another innovation in everyday clinical practice – pterygoid implants. Pterygoid implants are an alternative that uses the remaining bone to anchor implants, instead of bone augmentation procedures.

Pterycore Implants

​

PteryCore implants are used in cases where the upper jaw sinus cavity has expanded and prevents implantation in that region. They are placed in the pterygomaxillary region of the upper jaw, thus eliminating the need for a sinus lift. By placing the implant in the pterygoid process of the sphenoid bone, it is possible to ensure additional support in the bone, thus improving the stability and longevity of the implant.

​

With their deep threads, PteryCore implants provide extremely strong retention to ensure primary implant stability. Due to the anatomy of the jawbone, the length of the implants ranges between that of the longest conventional implants and that of zygomatic implants, providing a stable base for further procedures.

 

PteryCore Implants are designed to have a smooth surface at their “neck”, followed by a layer treated with the Resorbable Blast Media (RBM) process. The smooth “neck” surface at the top of the implant prevents the adhesion of microorganisms associated with periodontal infections, thus reducing the chances of an inflammatory process developing there. On the other hand, the RBM-treated surface improves the bone-to-implant contact (BIC) and thus facilitates osseointegration.
