If your dentist just told you that you do not have enough job for a regular implant and he also mentioned that subperiosteal is the option, slow down before you make any booking. This device has a complicated history and it was nearly abundant in 1990 because of the high failure rates, then brought back in the redesigned, 3-D printed form. Not every clinic is offering it today and using a new version, and mixing up the two can mean the difference between a working tooth and a painful reversal every two years from now.
What Is a Subperiosteal Implant?
A subperiosteal implant is a custom metal frame that sit on the top of your jawbone under the gum. Instead of being screwed directly into the phone like a standard implant. Small parts extent through the gum, and the crown, bridge or the danger attaches to those posts.
It is specifically designed for the people who have lost too much poor height for a conventional endosteal implant and do not want or they cannot tolerate a bone graft or sinus lift. The frame is built from a 3-D scan of your exact job sheet so no two implants are identical and this is made to order device, not an off the shelf part.
Subperiosteal vs. Endosteal vs. Zygomatic: Which One Actually Fits Your Case?
Most patients are only shown one option by their dentist. Here’s how the three main implant types actually compare, based on current oral surgery literature.
| Factor | Endosteal Implant | Subperiosteal Implant | Zygomatic Implant |
| Placement | Screwed into the jawbone | Rests on top of the bone, under the gum | Anchored in the cheekbone |
| Best for | Adequate bone height/width | Severe bone loss, graft not wanted | Severe maxillary bone loss |
| Bone graft usually needed? | Sometimes | No | No |
| Reported long-term success | 90%+ over 10 years for most patients | Highly variable — see next section | 95%+ in specialist centers |
| Recovery | Weeks to months | Faster initial healing, but frame exposure risk long-term | Longer, more complex surgery |
| Typical candidate | Most adults with healthy bone | Elderly or medically compromised patients avoiding grafts | Patients who’ve failed grafting attempts |
The takeaway is that the subperiosteal implants are not a better version of a regular implant and they are a fallback option for people who genuinely can not get the standard one, or don’t want extra surgery to build up bone.
Subperiosteal Implant Success Rate: What Recent Studies Actually Found
This is the part that most of the clinic website class over and it is a single most important thing to understand before deciding.
Older subperiosteal implants pre-2015, made from molds rather than digital scans had notoriously poor long-term outcomes. A widely cited long-term analysis found a survival rate around 54% and a true success rate of only about 25%, with implants that had three posts exposing through the gum faster than those with two.
The newer, 3D-printed titanium versions look better on paper but still carry real risk over time:
- A 6-year follow-up of 61 modern 3D-printed subperiosteal implants in 36 patients found only 9 of the 36 cases were still classified as fully successful at year six, while 27 cases developed complications including frame exposure and late mobility from recurrent infection.
- A separate case series following 21 custom subperiosteal implants in atrophic maxillae reported a much stronger 95.2% survival and success rate at both 1 and 5 years, with minimal bone loss under the abutments.
- A 2026 systematic review and the matter analysis, current through November 20 25 concluded that the customized 3-D printed subperiosteal implants arguing predictable short term results but long-term outcomes are limited by the soft tissue complications and the survival alone over state the real clinical success. The review recommends these implants be reserved as a salvage option for carefully selected patient is not the first line choice
What this means for you
The results vary enormously by the clinic, patient bone quality, and implant design generation. Ask your surgeon directly if the implant is CAD/CAM-designed from a digital CBCT scan and 3D-printed in titanium, not molded from an impression. That single question separates the modern approach from the outdated one with much higher failure rates.

Subperiosteal Implant Procedure: What Actually Happens, Step by Step
3D imaging
A CBCT scan maps your exact jawbone shape.
Digital design
The frame is designed in CAD software to match the bone surface precisely.
3D printing
The custom titanium frame is printed and finished (typically several weeks of lead time).
Placement surgery
The frame is placed directly on the bone under the gum, with posts left protruding like the average surgical time in one recent case series was around 44 minutes.
Healing and monitoring
Unlike endosteal implants, there’s often no waiting period for osseointegration since the frame doesn’t fuse into the bone but gum health around the posts needs close, ongoing monitoring for life.
Restoration
A crown, bridge, or denture is attached to the exposed posts.
Subperiosteal Implant Cost in 2026 — And What Insurance Actually Pays
Subperiosteal implants cost more than standard implants because of the custom design, imaging, and lab fabrication involved.
| Item | Typical 2026 Range |
| Standard single endosteal implant (post + abutment + crown) | $3,000 – $6,000 (RealDentalCosts 2026 data) |
| Subperiosteal implant (full custom frame, per arch) | Often $8,000 – $20,000+ depending on arch coverage and lab fees |
| Average out-of-pocket after insurance, standard implant | $1,500 – $4,500 (Dental Plus Clinic, 2026) |
| Typical annual dental insurance maximum | $1,000 – $2,000 per year, regardless of treatment cost |
Here’s the part that catches people off guard that most of the dental insurance plans still classify implants including subperiosteal implants and as a major procedure reimbursed around 50%, but only after your deductible, and only up to your plan’s annual maximum. If your plan caps out at $1,500 and the procedure costs $12,000, insurance covers a small fraction of the total, not half of it.
Many plans also carry a missing tooth clause, which can deny any implant coverage if the tooth was lost before your policy started. Before scheduling anything, get your treatment plan’s CPT/CDT codes and call your insurer to confirm, in writing, exactly what percentage and dollar amount they’ll pay and verbal quotes from a front desk are not a guarantee.
Subperiosteal Implant Indications: Are You Actually a Candidate?
You’re typically a reasonable candidate if:
- You’ve lost significant jawbone height or width, especially in the upper jaw
- You want to avoid, or medically can’t undergo, bone grafting or a sinus lift
- You’re missing multiple teeth in one arch, not just one isolated tooth
- You’re committed to frequent follow-up visits for the life of the implant
You’re usually not a good candidate if:
- You smoke heavily (raises infection and exposure risk substantially)
- You have uncontrolled diabetes or an autoimmune condition affecting healing
- You want a “set it and forget it” solution with minimal maintenance
- A standard implant with a graft is realistically achievable and better documented long-term
Before You Book: The One Conversation That Matters Most
A subperiosteal implant can restore the function and the confidence when a bone craft is not realistic but the data shows outcomes swing widely based on the implant design, your surgeon experience with the technique and also how close you are not needed after work. Make sure to ask to see your surgeons own case outcomes, not just published averages before you are committing to anything.
If cost and coverage are part of what’s holding you back from deciding, it’s worth understanding your dental plan’s real numbers before treatment, not after. InsureOmni can walk you through dental insurance options that actually account for major procedures like implants, so you’re not guessing at what you’ll owe. No pressure, just clarity while you weigh your options.
