Zirconia vs. titanium implants: a complete guide

Titanium or zirconia? The million-dollar question

If you need a dental implant and have been researching your options, you have probably come across two main materials: titanium and zirconia. Titanium has been the standard for decades, but zirconia has emerged as a compelling alternative. So which is better? The answer depends on your individual case.

Titanium: the established choice

Titanium has been used in implant dentistry since the 1960s. Its main advantage is its extensive clinical track record -- we have decades of data confirming its efficacy. It osseointegrates well with bone, and the surgical techniques have been thoroughly refined.

However, titanium implants are actually alloys that contain other metals such as vanadium, aluminium, and in some cases nickel. These alloys can cause galvanic corrosion when they coexist with other metals in the mouth, release metal ions into the bloodstream, and trigger hypersensitivity reactions in susceptible patients.

Zirconia: the biological alternative

Zirconia implants are made from zirconium dioxide (ZrO₂), an extremely strong ceramic material. Their main advantage is that they are 100% metal-free: no alloys, no corrosion, no ion release.

From an aesthetic standpoint, zirconia is white (like a natural tooth), while titanium is grey. In patients with thin gums, titanium can create a dark shadow visible through the gingival tissue. Zirconia eliminates this problem entirely.

The ceramic surface of zirconia also exhibits lower bacterial adhesion than titanium, which reduces the risk of peri-implantitis over the long term.

Which is best for whom?

Zirconia is especially recommended for patients with metal sensitivity (confirmed by the MELISA Test), thin or receding gums, autoimmune conditions, or simply those who prefer metal-free dentistry.

Titanium may be suitable for patients with no metal sensitivity who prioritise lower cost, although from the perspective of biological dentistry, zirconia will always be the first choice due to its superior biocompatibility.

Our recommendation

At Bio Salud Dental, we favour zirconia implants as our first option. We have over 30 years of experience working with biocompatible materials, and our clinical practice confirms that zirconia offers the best balance of aesthetics, biocompatibility, and durability. We always recommend performing the MELISA Test before choosing the implant material, so that the decision is informed and personalised.
