Endosteal vs. Subperiosteal – Which one should you choose?

Missing teeth can significantly impact your confidence, smile aesthetics, and even your ability to chew comfortably. Fortunately, dental implants offer a revolutionary solution, restoring both the functionality and beauty of your natural teeth. However, with two primary implant types – endosteal and subperiosteal – navigating the world of dental implants can be overwhelming. This in-depth guide will equip you with the knowledge to make an informed decision about which implant best suits your needs.

According to a 2021 study published in the National Institutes of Health’s Journal of Dental Research, endosteal implants account for over 90% of all dental implant procedures performed worldwide. Research suggests subperiosteal implants may have a lower success rate compared to endosteal implants. 

However, subperiosteal implants can still be a viable option in certain situations. This blog post will delve into the key differences between these two implant types to help you make an informed decision.

What are Endosteal Implants

Endosteal implants are tiny screws or cylinders surgically placed directly into your jawbone, acting like artificial tooth roots. These implants fuse with the jawbone over time, providing a strong foundation for a permanent crown, bridge, or denture. 

Here’s a breakdown of their key features:

  • Placement: 

Endosteal implants are surgically placed directly into the jawbone, mimicking the function of a natural tooth root.

  • Material: 

They are typically crafted from biocompatible titanium, a strong and durable metal that integrates seamlessly with the jawbone.

  • Success Rate: 

Endosteal implants boast exceptional success rates, often exceeding 90%. This high success rate is attributed to their secure placement within the jawbone and the well-documented biocompatibility of titanium.

  • Procedure: 

The endosteal implant procedure typically involves two surgical stages. In the first stage, the implant is placed in the jawbone, and a healing period of several months allows for osseointegration (fusion between the implant and bone). 

During the second stage, a minor surgery is performed to uncover the implant, and an abutment is attached. Finally, the permanent crown, bridge, or denture is secured onto the abutment.

What are Subperiosteal Implants

Subperiosteal implants are an alternative option for those with low jawbone density. These are placed on top of the jawbone, beneath the gum tissue. They are generally recommended for patients with insufficient jawbone density for endosteal implants. Here’s a closer look at their characteristics:

  • Placement: 

Unlike endosteal implants, subperiosteal implants rest on the surface of the jawbone, secured with posts or screws.

  • Material: 

A metal framework typically forms the base of subperiosteal implants.

  • Success Rate: 

While subperiosteal implants can be effective, they generally have a lower success rate compared to endosteal implants. This can be attributed to the lack of direct bone integration and a higher risk of implant movement.

  • Procedure: 

The subperiosteal implant procedure usually involves a single surgical stage. The implant framework is placed on the jawbone and secured, and the artificial teeth are attached directly to the framework.

Endosteal Vs Subperiosteal Implants

Considering dental implants to replace missing teeth? While they offer a long-lasting solution, you’ll encounter two main options: endosteal and subperiosteal implants. Here’s the main difference between the two:

Feature Endosteal Implants Subperiosteal Implants
Placement Placed directly into the jawbone Rests on top of the jawbone, secured with posts or screws
Material Typically titanium Metal framework
Success Rate 90%-95% 87.7%
Procedure Two surgical stages (implant placement and attachment of crown/bridge/denture) Typically one surgical stage (placement of framework and attachment of artificial teeth)
Ideal Candidate Patients with adequate jawbone density Patients with insufficient jawbone density
Advantages Superior stability, mimics natural tooth function, high success rate May be suitable for patients with low jawbone density
Disadvantages Requires sufficient jawbone density, two-stage surgical procedure Lower success rate, may not feel as natural as endosteal implants
