The subperiosteal implant is a specialized metal framework system placed on the upper surface of the jawbone, between the periosteum (membrane beneath the gum tissue) and the bone. Unlike conventional implants, this type does not penetrate into the bone and does not fuse with it. Developed in the past for patients with insufficient bone volume, this method is rarely preferred today due to the availability of much more effective alternatives.

Subperiosteal Implant: A Historical Dental Solution and Modern Alternatives

Important Note: Subperiosteal implants are a largely abandoned method today. Modern dentistry offers much more successful alternatives for patients with bone loss.


Key Differences from Conventional Implants

The main differences between subperiosteal implants and conventional implants are:

  • Placement location: Placed on top of the bone, not inside it
  • Integration: Does not fuse with the bone; is only surrounded by soft tissue
  • Stability: Provides mechanical retention, no biological integration
  • Reason for application: Developed as an alternative for cases with insufficient bone volume

In our modern implantology practice, we prefer to increase bone volume through methods such as bone grafting and sinus lifting for patients with bone deficiency, followed by conventional implant placement.


Application Mechanism and Process

How Does a Subperiosteal Implant Work?

  1. Impression stage: In the first surgery, the jawbone is exposed and an impression is taken from the bone surface
  2. Implant fabrication: A custom metal framework is manufactured in the laboratory
  3. Placement surgery: In the second surgery, the metal framework is placed on top of the bone
  4. Healing process: Over approximately 3-6 months, soft tissues envelop the implant
  5. Prosthesis attachment: Teeth are fixed to the abutment points extending from the metal framework

Our Clinical Experience: In our 20 years of practice, we have not performed subperiosteal implant placement. This is because much more successful modern methods exist for the same patients.


Suitable Candidate Criteria (Historically)

Subperiosteal implants were previously considered in these situations:

Candidate Situations

  • Patients with severe bone loss
  • Cases where bone grafting was not possible
  • Patients whose general health was not suitable for major surgery
  • Alternative options sought for elderly patients

Today's Reality

We now offer more effective solutions for all of these situations:

  • All-On-4 system for fixed teeth with minimal bone
  • Zygomatic implants for graft-free treatment options
  • Short implants and tilted placement techniques

Advantages and Disadvantages Analysis

AdvantagesDisadvantages
No bone penetrationDoes not fuse with bone
No bone graft requiredHigh failure risk
An option for elderly patientsLong treatment duration (2 surgeries)
-Gum problems and maintenance issues
-Risk of bone erosion
-Poor oral hygiene

Our Clinic's Approach: Due to these disadvantages, we recommend modern alternatives to our patients. We can always find a solution for every patient with bone loss.

Frequently Asked Questions

Answered by our specialist

Why are subperiosteal implants not used today?
Modern dentistry has developed much more effective, safe, and long-lasting alternatives for patients with bone loss. While All-On-4, zygomatic implants, and bone grafting techniques have success rates above 95%, subperiosteal implants have only a 60-70% success rate.
I have extensive bone loss, can I still get implants?
Absolutely! With modern techniques, even when bone quantity is very low, successful treatment is possible with zygomatic implants, All-On-4 system, or bone grafting. At our clinic, we can evaluate your condition with 3D tomography and recommend the most suitable solution.
What is the difference between All-On-4 and subperiosteal implants?
With All-On-4, implants are placed inside the bone and fuse with it, lasting a lifetime. With subperiosteal implants, the metal framework sits on top of the bone, does not fuse, and can cause problems within 5-10 years. All-On-4 is a much safer and more permanent solution.
I am over 70, is implant treatment risky?
Age alone is not a barrier to implant treatment. If your general health is suitable, successful implant treatment can be performed even at ages 80-90. Minimally invasive methods like All-On-4 are particularly ideal for elderly patients. Learn more about implant treatment in elderly patients.
I have subperiosteal implants and am experiencing problems, what should I do?
If your existing subperiosteal implants are causing problems, they can be removed and replaced with modern implant systems. We recommend visiting our clinic to evaluate your condition. We can always find a better solution.
