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.
Pterygoid Implants – Before & After Results
Clinical Case 01
- Age: 57
- ASA 2: No medications taken. Healthy Female Terminal Dentition with failing dentition due to caries & extractions.
- Patient request: To give her a smile back!
- Tx Plan: Extraction of remaining teeth and place Anterior implants and single zygo and pterygoids
- Tx performed: placed two anterior implant and two Unilateral zygo and one pterygoid (right)
- Prosthesis: upper and lower fix implant bridge with Zr dentures.
Clinical Case 02
- Age: 45
- ASA 1: No drug allergy or medications. Patient came to see us because his previous dentist placed lower dental implants but unable to finish the
- Prosthesis: We successfully placed a new bridge and he is asking us to make his upper jaw with permanent implant bridge.
- Tx Plan: Place two unilateral zygo and pterygoid implant with two transnasal (anterior) to avoid quad zygos. This allow us to save bone to receive superior zygo if there is a need.
- 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.
Technique and Instruments of Pterygoid
- Osteotome (Norris Medical) No 1 (2mm) and no 2 (3mm).
- Drills (Just no 1).
- The average length of the implant is 16-20mm. Same trajectory, your drill.
- Long driver (45mm) to place the implant and test torque value should be around 35-45cm.
- AP position: 3rd molars entry. Feel for the hamular notch. Anterior 10mm. 30 degrees inward.
- Remember to have proper Medial-lateral angulation to engage into the PterygoMaxillary complex.
- Blind osteotome and drilling for insertion and hear the audible difference into dense type 1 bone.
What Are Pterygoid Implants? Advanced Dental Implants Explained
Pterygoid Implants
A pterygoid dental implant is a specialized type of implant placed in the pterygoid region of the upper jaw, near the back of the mouth. Instead of being anchored in the regular upper jaw bone, maxilla, it is inserted into the pterygoid bone behind the maxillary sinus, an area with dense, stable bone.
Why are pterygoid implants used? They are typically recommended for patients who have severe bone loss in the upper back jaw, want to avoid bone grafting or sinus lift procedures, need a stable solution for upper dentures or full arch restorations.
Key benefits
No bone grafting required in many cases.
Provides strong anchorage in dense bone.
Can support full arch restorations.
Often allows for faster treatment timelines. Pterygoid dental implants are often used in full arch restorations, like all-on-four or implant-supported dentures. Placed in the dense pterygoid bone, they provide extra stability, helping you chew, speak and smile with confidence.

Frequently Asked Questions About Pterygoid Implants
How are pterygoid dental implants different from traditional upper jaw implants?
Traditional implants in the upper jaw rely on bone in the posterior maxilla, which is often thin in patients with advanced bone loss. Pterygoid implants are placed farther back, anchoring into the dense pterygoid plate region. As this area offers stronger structural support, it allows implant placement even when conventional posterior bone volume is limited.
Do pterygoid implants eliminate the need for sinus lifts or bone grafting?
In many cases, yes. Patients who would normally require sinus augmentation procedures may avoid them because pterygoid implants bypass the sinus cavity entirely. By utilizing existing dense bone farther back in the jaw, treatment can often proceed without additional grafting surgeries, reducing overall treatment time.
Are pterygoid implants used alone or with other advanced implant techniques?
They are frequently part of a comprehensive full-arch rehabilitation plan. Depending on bone availability, pterygoid implants may be combined with anterior, transnasal, or zygomatic implants to provide a stable foundation for a fixed prosthesis. The exact configuration depends on the patient’s anatomy and long-term restorative goals.
Is the placement of pterygoid implants more complex?
Yes. This is a highly specialized procedure that requires advanced training and detailed 3D imaging. Due to the angulation and posterior location, precise surgical planning is essential. Experienced implant surgeons use digital diagnostics to carefully map placement and ensure predictable outcomes.
What type of restoration is typically placed on pterygoid implants?
Pterygoid implants are most often used to support a fixed full-arch bridge. These restorations are designed to feel stable and secure, providing improved chewing function and aesthetics compared to removable dentures. Materials such as zirconia may be used to achieve durability and natural appearance.
Who is considered a strong candidate for pterygoid implants?
Patients with moderate to severe upper-jaw bone loss who wish to avoid removable dentures may benefit most. Ideal candidates are generally in good overall health and able to undergo implant surgery. A detailed evaluation, including imaging and medical review, determines candidacy.
Is sedation available during pterygoid implant surgery?
As these procedures can be more involved than standard implant placement, sedation options are often recommended to enhance comfort. At Dr. Edward Liu Sedation and Implant Dentistry, patient comfort is prioritized, and sedation techniques may be incorporated based on individual needs and medical history.
What is the recovery timeline for pterygoid implant procedures?
Healing time varies depending on whether implants are placed alone or as part of a full-arch reconstruction. Many patients experience typical post-surgical swelling and mild discomfort for several days. Osseointegration, or the bonding of the implant to bone, occurs over several months before final restorations are secured.
How long do pterygoid implants last?
With proper placement and good oral hygiene, dental implants are designed to provide long-term support. Regular professional maintenance and home care are essential for protecting both the implants and the surrounding tissues.
Why should I seek a specialist for pterygoid dental implants?
As this technique involves complex anatomy and advanced surgical planning, choosing a provider experienced in full-arch rehabilitation and complex implant cases is critical. A skilled implant dentist can evaluate whether pterygoid implants offer a viable option for fixed, functional teeth, even in cases of significant bone resorption.
