A subperiosteal implant is a type of dental implant placed on top of the jawbone, just under the gum tissue. It’s a solution for people who don’t have enough healthy bone for traditional implants. Instead of being inserted into the bone, the implant sits over it and holds replacement teeth in place using a custom-made metal frame.
This option is often recommended for patients who cannot undergo bone grafting or those with shallow jawbones. It’s a less invasive alternative that still offers a secure fit for prosthetic teeth. If you’re exploring advanced dental solutions like subperiosteal implants or orthodontics in Windham, understanding how these treatments work can help you make informed decisions about your oral health.
How a Subperiosteal Implant Works
A subperiosteal implant functions differently from the typical implants most people are familiar with. Instead of being drilled into the bone, it rests above it.
Key Components:
-
A metal frame designed to fit your specific jaw shape
-
Posts attached to the frame that extend through the gums
-
Artificial teeth that are anchored to the exposed posts
Placement Process:
-
First, your dentist takes impressions or scans of your jaw to create a precise model.
-
A dental lab uses this to fabricate the metal frame.
-
During a minor surgery, the frame is positioned over your jawbone.
-
The gums then heal around the frame, holding it in place securely.
-
Once healed, artificial teeth are attached to the posts.
Because it doesn’t rely on bone density, a subperiosteal implant is often a good fit for patients with significant bone loss. It can also reduce the need for complex bone-building procedures, making the entire process quicker and easier for some people.
When Is a Subperiosteal Implant Recommended?
A subperiosteal implant isn’t the most common type of dental implant, but it serves an important purpose. Dentists may suggest it for patients who aren’t good candidates for traditional implants due to bone loss or other health-related concerns.
Situations Where It’s Often Used:
-
The jawbone is too shallow or thin for standard implants
-
Bone grafting isn’t an option due to medical conditions or personal preference
-
Multiple teeth are missing, especially in the back of the mouth
-
Patients need full arch restoration but can’t support standard implants
Why Dentists Recommend It:
-
It avoids the need for bone augmentation surgery
-
The treatment process is typically shorter
-
It’s custom-designed for your unique jaw shape, improving comfort and fit
-
Healing time may be reduced since the implant sits above the bone
If your jawbone has worn down over time or you’ve been told standard implants aren’t possible, a subperiosteal implant might be a practical alternative. It’s always important to consult with an experienced implant dentist to review your options based on your bone structure and overall oral health.
Benefits of Choosing a Subperiosteal Implant
For patients who can’t get traditional implants, a subperiosteal implant offers several practical advantages. It’s not just about replacing missing teeth—it’s about finding a method that works with your current bone structure and overall health.
Main Benefits:
-
No bone grafting required – A big advantage for those with bone loss or medical conditions that make surgery difficult.
-
Quicker treatment timeline – Since there’s no need for bone healing, the entire process can move faster.
-
Less invasive procedure – The implant frame is placed above the bone, which often means a shorter recovery.
-
More accessible for older adults – Especially helpful for patients who may not be eligible for more complex procedures.
-
Custom fit for your jaw – Designed specifically for the contours of your mouth, improving both stability and comfort.
A subperiosteal implant isn’t just a fallback. For the right patient, it’s a reliable and long-lasting solution that avoids additional surgeries while still providing secure support for replacement teeth.
Step-by-Step: The Subperiosteal Implant Procedure
Getting a subperiosteal implant involves several important steps. Each phase is designed to make sure the implant fits well, functions properly, and feels comfortable long-term.
1. Initial Consultation
-
A dental exam, X-rays, and 3D scans are taken.
-
The dentist checks the shape and size of your jawbone.
-
Impressions or digital scans are used to create a custom design.
2. Designing the Implant Frame
-
A dental lab fabricates a metal framework that fits over your jawbone.
-
The design includes posts that will support your new teeth.
-
Every frame is made to match your individual anatomy.
3. Surgical Placement
-
The dentist makes a small incision in the gum.
-
The frame is positioned over the jawbone.
-
The posts extend through the gum to allow for tooth attachment later.
4. Healing Period
-
The gums heal and form around the frame.
-
This healing stage usually takes a few weeks.
-
Temporary teeth may be worn during this time.
5. Attaching the Prosthetic Teeth
-
Once healed, permanent artificial teeth are connected to the posts.
-
The result looks and functions like natural teeth.
The subperiosteal implant process is often quicker and less invasive than traditional implant methods, especially for those who don’t have enough bone to support other options.
Potential Risks and Complications
Like any surgical procedure, a subperiosteal implant comes with some risks. While most patients heal well and enjoy long-term success, it’s important to understand what could go wrong and how to reduce the chances of complications.
Common Risks to Be Aware Of:
-
Gum irritation or swelling – Especially during the healing stage, some soreness is expected.
-
Implant shifting – Rare, but it can happen if the frame doesn’t fit properly or healing is disrupted.
-
Infection – Any oral surgery carries a small risk of infection, but this is manageable with proper care.
-
Gum recession – In some cases, the metal posts may become more visible if gums recede over time.
How to Reduce Risk:
-
Follow all post-op instructions from your dentist
-
Keep up with regular dental visits
-
Avoid smoking, as it can slow healing and increase infection risk
-
Maintain good oral hygiene with gentle brushing and rinsing
A subperiosteal implant is generally safe, especially when placed by an experienced professional. Most issues can be avoided or addressed early with the right care and follow-up.
Cost of a Subperiosteal Implant and Insurance Coverage
The cost of a subperiosteal implant can vary based on several factors, but it tends to be similar to or slightly higher than traditional dental implants due to the custom fabrication and surgical steps involved.
What Affects the Price:
-
Number of implants needed – Full-arch replacements typically cost more than single tooth solutions.
-
Complexity of the case – Patients with additional health concerns may require extra planning or care.
-
Dental provider’s location and experience – Practices in urban areas or with highly specialized professionals may charge more.
-
Materials used – Custom metal frameworks and high-quality prosthetics can affect overall cost.
Insurance and Payment Options:
-
Some dental insurance plans cover part of the procedure
-
Pre-authorization may be needed before starting treatment
-
Health savings accounts (HSA) or flexible spending accounts (FSA) can often be used
-
Many providers offer financing or payment plans
Before moving forward with a subperiosteal implant, it’s important to have a clear discussion about costs and what your insurance may help cover. This ensures there are no surprises and you can plan accordingly.
Subperiosteal Implant vs. Other Dental Implant Types
Not all dental implants work the same way. A subperiosteal implant is just one option among several. Knowing the key differences can help you understand why a dentist might recommend one over another.
Quick Comparison:
| Type of Implant | Placement | Bone Requirement | Healing Time | Best For |
|---|---|---|---|---|
| Subperiosteal Implant | Above jawbone, under gums | Minimal bone needed | Shorter | Patients with bone loss |
| Endosteal Implant | Inside jawbone | Sufficient bone required | Longer | Most common, ideal bone support |
| Zygomatic Implant | Anchored in cheekbone | For severe bone loss cases | Longer and complex | Patients with extreme bone loss |
Why Choose One Over Another:
-
Subperiosteal implant is often chosen when bone grafting isn’t possible
-
Endosteal implant is preferred when the jawbone is healthy and strong
-
Zygomatic implant is a last-resort option, typically used in extreme cases
The right implant depends on your bone condition, overall health, and long-term goals for function and appearance. A thorough exam and consultation will help determine the best fit.
