A subperiosteal implant is a modern solution for patients who have been told they do not have enough bone for traditional dental implants.
Instead of placing a titanium post inside the bone, a subperiosteal implant is a custom made titanium framework that rests on top of the jawbone and underneath the gums. The posts of this framework come through the gums and support your new teeth. For patients with significant bone loss, this design can provide stability, comfort and long term function without requiring bone grafting.
At Smart Arches, we use advanced imaging, digital planning and custom 3D printing to create subperiosteal implants that match a patient’s exact anatomy. This helps us give patients who have been turned away elsewhere a second chance at permanent, secure teeth.
What Is a Subperiosteal Implant?
A subperiosteal implant is a custom shaped titanium framework designed to fit over the surface of the jawbone. It sits beneath the gum tissue. Small attachment posts extend through the gums so your doctor can secure a bridge or a full set of teeth. Unlike traditional implants that must be placed into healthy bone, subperiosteal implants work well for patients with severe bone loss.
A subperiosteal implant is a type of dental implant placed on top of the jawbone and beneath the gum tissue, rather than into the bone like traditional endosteal implants.
Instead of a screw inserted into bone, a subperiosteal implant uses a custom-fit metal framework that sits securely on the surface of the jaw. Small posts extend through the gum, and the replacement tooth or full-arch prosthesis attaches to these posts.
How It Differs From Traditional Implants
| Feature | Endosteal Implant | Subperiosteal Implant |
|---|---|---|
| Placement | Inserted into the bone | Rests on top of the bone |
| Bone Required | Requires sufficient bone height & density | Ideal for patients with severe bone loss |
| Bone Grafting | Often needed | Usually not needed |
| Customization | Standard sizes | Fully custom-made using 3D imaging |
| Who It Helps | Most implant candidates | Patients unable to support traditional implants |
Who Needs a Subperiosteal Implant?
Subperiosteal implants are recommended for patients who:
- Have significant jawbone loss due to dentures, periodontal disease, trauma or natural aging
- Have been told they do not have enough bone for traditional implants
- Do not want or cannot undergo bone grafting or sinus lift procedures
- Need a stable replacement for loose dentures
- Prefer a faster, more predictable treatment plan when bone is limited
Because the framework rests on top of the bone, patients can still qualify even when the ridge is thin or fla
Benefits of a Subperiosteal Implant
Subperiosteal implants offer several advantages for the right patient. They do not require bone grafting. They use a custom fit design that follows the natural shape of your jaw. They provide strong support for full arch teeth. They reduce treatment time because there is no need to wait for grafted bone to heal. They are made from medical grade titanium, which is highly biocompatible and extremely durable.
Most importantly, they give patients stable, natural looking teeth in situations where traditional implants are not possible.
How We Create a Subperiosteal Implant
Smart Arches uses a fully digital workflow to ensure precision and comfort.
- Step 1: A 3D CT scan captures an accurate model of your jawbone.
- Step 2: Your doctor designs a custom titanium framework using CAD software.
- Step 3: The design is manufactured through high resolution 3D metal printing.
- Step 4: The framework is polished, prepared and sterilized for surgery.
This process allows us to produce a patient specific implant that fits your bone surface with remarkable accuracy.
Comparison: Subperiosteal Implants vs. Zygomatic Implants vs. Bone Grafting
| Feature | Subperiosteal | Zygomatic | Bone Graft + Endosteal |
|---|---|---|---|
| Bone Requirement | Very low | Very low | High |
| Surgical Complexity | Moderate | High | Moderate–High |
| Custom Designed | Yes | No | No |
| Healing Time | Short | Long | Long |
| Ideal For | Severe ridge atrophy | Extreme maxillary atrophy | Patients with adequate donor bone |
How the Procedure Works
During the procedure, your doctor uses anesthesia to keep you comfortable. The gum is gently lifted to expose the top of the bone. The custom titanium framework is placed on the bone and secured with tiny titanium screws. The gums are then closed around the posts that will support your future teeth. Once the tissue has healed and the framework is stable, your new teeth are attached to the posts. The result is a secure, fixed smile that does not move or shift.
Success Rates and Modern Improvements
Older subperiosteal implants from the 1940s through the 1980s had higher complication rates because surgeons had to take physical impressions of exposed bone and cast implants by hand. Today, with digital design and 3D printing, the precision and fit are dramatically improved. Recent studies show survival rates in the range of 85 to 96 percent over several years, along with high patient satisfaction. Modern materials, advanced imaging and single stage surgical techniques have made subperiosteal implants a far more reliable option.
Is a Subperiosteal Implant Right for You?
If you have been told that you do not have enough bone for dental implants, a subperiosteal implant may be the solution that finally gives you stable, secure teeth. At Smart Arches, we evaluate each patient individually so we can recommend the safest, most predictable option. For some people, a traditional implant or bone graft is still the best path. For others, a subperiosteal implant offers a faster and more stable alternative.
