What Are the 3 Types of Dental Implants?

Table of Contents:

If you are researching tooth replacement, the question “What are the 3 types of dental implants?” is worth answering early. The three main types are endosteal, subperiosteal, and zygomatic implants. Each option suits a different level of jawbone health. This guide explains how each type works, who qualifies for it, and how to select the right one with your dentist.

What Is a Dental Implant?

A dental implant is a small post, usually made of titanium, which a dentist places into or onto your jaw to support a replacement tooth. The post acts as an artificial root. Your bone bonds with it through a process called osseointegration, and your dentist then attaches a custom crown on top. Research published by the National Institutes of Health reports long-term survival rates above 96 percent. 

What Are the 3 Types of Dental Implants?

Dentists group implants into three categories based on where the post sits in relation to your jawbone.

1. Endosteal Implants 

Endosteal implants are the most common type used today. Your dentist surgically places these screw-shaped titanium posts directly into your jawbone. Over three to six months, the bone fuses with the post, creating a stable base for a crown, bridge, or full-arch restoration, such as All-on-4 dental implants.

You are a strong candidate for endosteal implants if you have:

  • Healthy gums free of active gum disease.
  • Adequate jawbone height and density to hold the post.
  • Good overall health for smooth healing.
  • A commitment to daily brushing and flossing, and to routine dental visits.

Patients with mild bone loss still qualify for most grafting procedures. Our blog on dental bone grafts explains this preparatory step in detail.

2. Subperiosteal Implants 

Subperiosteal implants rest on the jawbone, beneath the gum tissue. A custom metal frame sits against the bone, and small posts extend through the gums to hold the replacement teeth.

Dentists recommend this type for patients who:

  • Lack enough natural bone height for endosteal posts.
  • Prefer to avoid bone grafting for personal or medical reasons.
  • Need a faster timeline, since no bone fusion period is required.

Subperiosteal implants are less common now because grafting techniques have improved. Still, they remain a practical option for select patients with significant lower jaw bone loss.

3. Zygomatic Implants 

Zygomatic implants are the least common and most complex of the three. Instead of anchoring in the jawbone, the surgeon places longer posts into the zygoma, which is your cheekbone. This approach serves patients with severe upper jaw bone loss who would otherwise need extensive grafting.

These posts bypass the upper jaw entirely, so poor bone quality there does not matter. A trained specialist performs the procedure under sedation, and patients often receive fixed temporary teeth the same day. Research published by the National Institutes of Health reports high success rates.

Dentists recommend zygomatic implants for patients who:

  • Have severe or advanced bone loss in the upper jaw.
  • Wish to avoid grafting and sinus lift surgeries.
  • Want fixed replacement teeth without a long healing wait.
  • Are healthy enough for a longer surgical procedure.

Dental Implant Types at a Glance

Implant Type Placement Best Suited For Bone Requirement Key Consideration
Endosteal implants Placed directly inside the jawbone Most patients replacing one, several, or all missing teeth Adequate jawbone height, width, and density Most common option; bone grafting may be needed before placement
Subperiosteal implants Positioned on top of the jawbone beneath the gums Patients with significant bone loss who cannot or prefer not to undergo grafting Limited natural bone may be acceptable Less commonly used because modern grafting procedures have improved
Zygomatic implants Anchored into the cheekbone instead of the upper jaw Patients with severe upper-jaw bone loss Does not rely on adequate upper-jaw bone Complex procedure requiring an experienced implant specialist

How to Choose the Right Implant Type

Your dentist will recommend the most suitable implant after completing a detailed evaluation, which generally includes the following steps: 
  • 3D imaging: A cone beam CT scan evaluates bone height, width, density, nerve position, and available space for safe implant placement.
  • Medical history review: Your dentist reviews conditions such as uncontrolled diabetes, immune disorders, medications, and heavy smoking because they may affect healing.
  • Oral examination: Healthy gums and infection-free teeth are essential before implant surgery, as active gum disease can increase the risk of failure.
  • Restoration planning: The number, location, and condition of missing teeth help determine whether you need one implant, an implant bridge, or a full-arch restoration.

Endosteal implants are suitable for most patients, while subperiosteal and zygomatic options are available for those with advanced bone loss. Our blog on who should not have dental implants outlines the factors that disqualify some candidates.

Benefits of Replacing Missing Teeth with Implants

All three types offer clear advantages over removable dentures:

  • They stimulate the jawbone and prevent bone shrinkage after tooth loss.
  • They restore up to 90 percent of natural chewing power.
  • They stay fixed in place and never slip while you eat or speak.
  • They do not require grinding down healthy neighboring teeth.
  • They last for decades with proper care. 

Conclusion

Endosteal, subperiosteal, and zygomatic implants each address tooth loss differently, and the right choice depends on your bone health, medical history, and restoration goals.

FAQs

Which type of dental implant is the most common?

Endosteal implants are the most commonly used type because they work well for patients with healthy gums and sufficient jawbone. They can support single crowns, dental bridges, or full-arch restorations.

Most patients experience less discomfort than expected because local anesthesia keeps the area numb during placement. Mild soreness, swelling, or tenderness may occur afterward but usually improves within several days.
Not every patient needs a bone graft. It is recommended when the jawbone lacks enough height, width, or density to support an implant. Other implant options may sometimes reduce the need for grafting.
Dental implants are considered safe when properly planned and placed by a qualified dentist. Implant systems are regulated, and long-term success is high when patients maintain good oral hygiene and regular dental visits.
