What Are Pterygoid Dental Implants, and Who Is a Good Candidate?
Dental implants are an excellent and reliable way for patients to replace missing teeth. However, they are not for everyone. Some patients with issues such as significant jawbone loss may be considering other options, including dentures and bridges. Fortunately, at Dr. Edward Liu Sedation and Implant Dentistry, patients can educate themselves further on solutions such as pterygoid dental implants that are used in specific situations.
What is a pterygoid dental implant?
Dr. Liu describes the pterygoid dental implant as a unique type and implant technique designed for patients with less bone structure. The success rate of these dental implants for those with moderate bone loss is much higher than with traditional implants. Pterygoid implants are much longer and larger and are used in the upper molar region. They are inserted far back in the mouth, typically where wisdom teeth once remained. They are placed at a specific angle, which allows them to be placed in places where a lack of jawbone may cause a patient to be a poor candidate for conventional implants. With a thorough evaluation and a series of dental x-rays, our team can determine if pterygoid dental implants are appropriate for a patient. Additionally, other implant types, such as zygoma implants, may be used along with pterygoid implants.

- Prosthesis: Ti bar with Zr bridge to achieve a fixed permanent bridge


Why should I consider a pterygoid dental implant?
Implants such as this are used in cases where patients need to replace missing teeth but might not be appropriate candidates for traditional dental implants. During an evaluation, our team can assess the patient’s current situation and make recommendations based on this information. These implants are best for those who might otherwise not be able to have implants placed.
