Types of Dental Implants: A Patient's Guide to Your Options

Dental implants are titanium or zirconia posts surgically placed in the jawbone to function as artificial tooth roots. Once osseointegrated, they support crowns, bridges, or full-arch prostheses. The right type depends on how many teeth are missing, where they are, and how much jawbone remains. This guide covers every implant-based tooth replacement option available in 2026.

Single Tooth Implants

A single tooth implant is the most straightforward case: one implant fixture, one abutment, one crown. The implant replaces the missing root; the crown replaces the visible tooth. Nothing is done to the healthy adjacent teeth — they are untouched, which makes implants fundamentally different from bridges.

Single implants are appropriate for:

• One missing tooth anywhere in the mouth
• Cases where the adjacent teeth are healthy and should not be altered
• Patients with sufficient bone volume at the missing tooth site

If bone has been lost at the site — common when the tooth has been missing for more than a year — socket grafting or ridge augmentation may be needed before implant placement.

Implant-Supported Bridges

When multiple consecutive teeth are missing, an implant-supported bridge uses two or more implants to anchor a multi-tooth prosthesis. Not every missing tooth requires its own implant — the bridge spans between the anchoring implants.

This is the implant-based equivalent of a traditional tooth-supported bridge, but without the requirement to grind down adjacent natural teeth as anchors.

Full-Arch Implants (All-on-4 and TeethNow)

Full-arch systems replace every tooth in one jaw using four to eight implants supporting a fixed prosthetic arch. The two main approaches:

All-on-4: Four implants per arch — two vertical in the front, two angled posteriorly to reach denser bone. Delivers provisional teeth within 24 hours. Titanium implants with acrylic or zirconia prosthetics. Well-documented clinical record.

TeethNow: The full-arch system at this practice uses six to eight zirconia implants per arch and a custom-milled zirconia final prosthesis. More implants, fully metal-free, and delivers the same-day provisional teeth. Suited for patients who want the highest-performance full-arch result.

Both systems are designed to eliminate the need for bone grafting in most cases by targeting dense bone in the anterior arch.

Mini Dental Implants

Mini implants have a diameter under 3 mm — roughly half that of standard fixtures. They are appropriate for:

• Stabilizing lower dentures in patients with limited bone volume
• Narrow spaces where a standard implant won’t fit
• Patients with health conditions limiting surgical complexity

Mini implants are not a general-purpose cost-saving alternative. Load-bearing capacity is lower, making them inappropriate for molar replacement in most cases. When correctly indicated, they work well. When substituted for standard implants inappropriately, they fail at higher rates.

Zygomatic Implants

Zygomatic implants solve the problem of severe upper jaw bone loss. Standard implants — including the angled All-on-4 design — require some jaw bone. When the posterior maxilla has resorbed severely, even angled implants may not have sufficient bone to anchor into.

Zygomatic implants bypass the jaw entirely. At 30–52 mm in length, they pass through the resorbed maxilla and anchor in the zygomatic bone (the cheekbone) — a dense structure unaffected by tooth loss. The result is a fixed full-arch restoration without bone grafting.

Dr. Igor Kaplansky, DDS — Diplomate ABOI/ID, Fellow AAID/FICOI/FAGD, ZAGA Center certified — is one of only 11 ZAGA-certified zygomatic implant specialists in the United States. The zygomatic implants page covers the procedure, candidacy, and outcomes in detail.

Implant-Supported Dentures

For patients who want more stability than a traditional removable denture but prefer a removable option over a fixed arch, implant-supported dentures offer a middle ground. Two to four implants in the lower arch provide snap-in retention — the denture clicks onto the implants and can be removed at night.

This is distinct from a fully fixed implant-supported arch. The denture still rests on the gum tissue for some support, but the implants prevent the floating and shifting of a traditional denture. Bone preservation is better than with a conventional denture, but less than with a fixed full-arch system.

Choosing the Right Option

The clinical decision depends on:

• Number and location of missing teeth
• Available bone volume and density at each site
• Whether adjacent natural teeth are involved
• Budget and timeline preferences
• General health and healing capacity

A 3D CBCT scan at consultation provides the information needed to match the right implant type to the patient’s anatomy. Consultations at Dentistry by Dr. Kaplansky in Gasport, NY are at no charge. Serving Lockport, Niagara Falls, Buffalo, and Western New York. Schedule an evaluation to find out which option fits your situation.
