Introduction to Dental Implants
Subperiosteal Implant. Dental implants have transformed the way people restore missing teeth. They provide a permanent solution that feels and functions like natural teeth. For most patients, endosteal implants those placed directly into the jawbone are the go-to option. However, for individuals with poor bone density or severe jawbone loss, a different type of implant is required: the subperiosteal implant.
What is a Subperiosteal Implant?
A subperiosteal implant is a custom-made metal framework designed to sit on top of the jawbone, but underneath the gum tissue. Unlike traditional implants that require drilling into the bone, subperiosteal implants rest on the bone surface, making them ideal for patients who lack sufficient jawbone density.
History of Subperiosteal Implants
Subperiosteal implants were among the earliest types of dental implants introduced in the mid-20th century. Back then, technology was limited, and precision was difficult to achieve. However, with modern 3D imaging and advanced surgical techniques, these implants have made a comeback as a safe and reliable solution.
How Subperiosteal Implants Differ from Endosteal Implants
The biggest difference lies in placement:
- Endosteal implants: Inserted into the jawbone.
- Subperiosteal implants: Placed on top of the jawbone, under the gums.
This distinction makes subperiosteal implants suitable for patients who cannot undergo bone grafting or those who want quicker treatment.
Who Needs a Subperiosteal Implant?
Subperiosteal implants are recommended for:
- Patients with significant bone loss in the jaw
- Older adults who cannot undergo bone grafting
- People who need a faster tooth replacement solution
- Patients looking for fixed dentures without invasive surgery
The Procedure Step by Step
- Consultation and Examination – A dentist evaluates bone structure using X-rays and CT scans.
- Impressions and Imaging – 3D scans help design a custom metal framework.
- Fabrication – The implant is crafted to fit the patient’s unique jaw shape.
- Surgery – The gum tissue is opened, and the implant framework is placed on the jawbone.
- Healing and Prosthetic Placement – After healing, artificial teeth are attached to the framework.
Materials Used in Subperiosteal Implants
Most subperiosteal implants are made of titanium, a biocompatible metal known for its durability and ability to integrate with bone tissue. Some may have special coatings that encourage gum tissue bonding and reduce infection risks.
Advantages of Subperiosteal Implants
- Avoids the need for bone grafting
- Custom-fit for each patient
- Shorter treatment time compared to grafting procedures
- Allows patients with poor bone quality to regain a fixed smile
Challenges and Risks
Despite their benefits, subperiosteal implants have some risks:
- Higher chance of infection compared to endosteal implants
- Implant exposure if gums do not heal properly
- Costly due to customization and surgical complexity
Subperiosteal Implant vs. Bone Grafting
Many patients with bone loss consider bone grafting first. However, bone grafts require several months of healing before implants can be placed. Subperiosteal implants bypass this by sitting directly on the bone, making them a faster option.
Recovery and Aftercare
Recovery usually takes a few weeks. Patients must:
- Maintain soft-food diets initially
- Follow strict oral hygiene routines
- Avoid smoking to reduce implant failure risk
- Attend regular dental check-ups
Longevity and Success Rates
Modern subperiosteal implants, when placed correctly, can last 10–15 years or longer. Success depends on oral hygiene, gum health, and the patient’s lifestyle. Advances in imaging and surgical techniques have significantly increased success rates.
Cost of Subperiosteal Implants
The cost ranges from $5,000 to $15,000 per arch, depending on complexity, materials, and clinic location. Since they are specialized implants, they often cost more than traditional implants. Insurance coverage varies, but financing options are commonly available.
Conclusion
Subperiosteal implants are a game-changing solution for people who cannot undergo traditional dental implant surgery due to bone loss. With modern technology, they are safer, more reliable, and more effective than ever before. If you’re considering dental implants but have been told you lack sufficient bone density, subperiosteal implants could be the perfect alternative.
FAQs
Q1. Are subperiosteal implants painful?
The procedure is performed under anesthesia, so discomfort is minimal. Some soreness is expected during recovery.
Q2. How long does it take to get a subperiosteal implant?
The process may take a few weeks, depending on the customization and healing time.
Q3. Can subperiosteal implants fail?
Yes, failure can occur if proper aftercare is not followed, or if gum infections develop.
Q4. Is the procedure safe for older patients?
Yes, it is often recommended for older patients with significant bone loss.
Q5. Can dentures be supported by subperiosteal implants?
Yes, they are often used to anchor dentures securely without slipping.
