All-on-6 Materials Explained: Titanium, Zirconia and What Lasts

An All-on-6 is built from two material layers: six titanium implants fused to your jaw, and a fixed bridge on top made of either acrylic-on-titanium or monolithic zirconia. Titanium is used for the implants because its surface reliably osseointegrates and has decades of evidence; zirconia is the most durable, stain-resistant choice for the visible bridge, while acrylic is lighter and cheaper. At Taki Dent in Antalya — Turkish Ministry of Health accredited and International Health Tourism authorised (Certificate ST-6335), led by Specialist Prosthodontist Dr. Sadık Taki — premium systems such as Straumann and Nobel Biocare are matched to each patient. Here is what every component is, and what actually lasts.

The two layers: what an All-on-6 is actually made of

It helps to separate the structure into the part you never see and the part you do. The foundation is six implants — titanium screws placed into the jawbone, angled to use the densest available bone and avoid the sinus and nerve. The prosthesis is the full-arch bridge that screws onto those implants, carrying the teeth and the pink gum-coloured portion. These two layers are made from different materials, chosen for very different reasons, and conflating them is the single most common source of confusion when patients compare quotes.

When a clinic quotes "zirconia All-on-6", they mean the bridge is zirconia — the implants underneath are still titanium. When they quote "acrylic" or "temporary", they mean the bridge. The implant system rarely changes between these options; what changes is the material sitting on top.

The implants: why titanium, and why the brand matters

Titanium dominates implant dentistry for one decisive reason: osseointegration. Its surface, especially when micro-textured by the manufacturer, allows living bone to grow onto and bond with the fixture, turning six separate screws into a single load-bearing foundation. Titanium is also tough enough to absorb the substantial forces of full-arch chewing without fracturing, and it has the deepest, longest clinical track record of any implant material.

This is where brand genuinely matters. Premium systems — Straumann and Nobel Biocare chief among them — invest heavily in surface technology, manufacturing tolerances and long-term research, which is why their published survival data is so strong and why their components remain available worldwide for years if a part ever needs replacing. A cut-price unbranded implant may look identical on an X-ray but lacks that evidence base and that future supply chain. For a fixed full-arch you will keep for decades, the implant system is not the place to economise — and it is the first thing a UK patient should pin down in writing.

The bridge: acrylic-on-titanium vs monolithic zirconia

The visible bridge is where you choose. The two mainstream options are very different materials with different lifespans:

Acrylic-on-titanium (PMMA). Acrylic teeth and pink gum bonded to a milled titanium bar. It is lighter, slightly shock-absorbing (which can be kinder to the integrating implants), and the most economical. Its limitation is durability: acrylic gradually wears, can stain over time and may chip, so an acrylic bridge often needs refurbishing or replacing after several years. This material is the standard for the immediate temporary bridge you receive on day one, and is a legitimate, lower-cost permanent option too.

Monolithic zirconia. A single milled block of zirconia — no separate teeth to debond. It is extremely hard, highly resistant to wear and staining, non-porous so it does not absorb fluids or odours, and the most lifelike under light. It is the premium permanent choice and the longest-lasting. The trade-offs are cost and its hardness, which makes a well-balanced bite and, often, a night guard important. We compare the two in depth in zirconia vs acrylic: which lasts longer.

So what actually lasts?

Ranked by longevity: the titanium implants last longest — engineered to serve for decades when the bone around them stays healthy. Among bridge materials, monolithic zirconia outlasts acrylic-on-titanium, often substantially, because it resists the wear, staining and chipping that eventually catch up with acrylic. But material is only half the story. The decisive variable in long-term success is not which material you pick — it is keeping the tissue and bone around each implant healthy.

This is the focus of Dr. Taki's research. His study of the factors influencing marginal bone loss around dental implants, in Quintessence International (2020), examined the variables that govern how much bone is preserved around each fixture (DOI: 10.3290/j.qi.a43864) — and a related strand of his work on single-crown restorations, in European Annals of Dental Sciences (2023), showed how finish-line design and material type shape the periodontal response and, with it, the durability of a restoration (DOI: 10.52037/eads.2023.0022). His accessible summary, What Really Drives Bone Loss Around Dental Implants, distils the practical takeaway: precise fit and disciplined maintenance protect the bone — and the bone is what makes any material last.

How material choice protects the bone

The link between material and longevity is real but indirect. A bridge that is accurately designed and milled — correct contours, cleanable undersides, a balanced bite — lets you keep the gum line and the bone around the implants free of plaque. A poorly contoured bridge, in any material, traps debris and invites the inflammation that drives bone loss. So the goal is not simply "choose zirconia"; it is choosing the right material and having it fabricated precisely by a prosthodontist-led team, then maintaining it. That is why CAD/CAM-milled bridges and proper occlusal balancing matter as much as the headline material name.

What UK patients should verify about materials

Before you travel, get written, specific answers — not brand-free reassurance:

• Implant system and exact model — e.g. Straumann BLX or Nobel Biocare N1, not just "premium titanium".
• Final bridge material — monolithic zirconia or acrylic-on-titanium — and what the temporary is made of.
• The written guarantee — Taki Dent provides a 5-year written guarantee; confirm what it covers for each layer.
• Genuine accreditation — confirm the clinic is Turkish Ministry of Health accredited and International Health Tourism authorised; Taki Dent's authorisation (Certificate ST-6335) is verifiable on the official Ministry of Health register.
• Your implant passport — insist on the implant brand, model and batch numbers in writing so a UK dentist can identify and service the components later.

The bottom line on materials

An All-on-6 is titanium where strength and fusion matter, and zirconia or acrylic where appearance and bite live. Titanium implants from an evidence-backed system such as Straumann or Nobel Biocare are the part you should never compromise on; monolithic zirconia is the most durable bridge, with acrylic-on-titanium a lighter, cheaper alternative. Yet the longest-lasting result comes not from the material name alone but from a precisely fabricated, prosthodontist-led restoration that you can keep clean. Done at an accredited clinic such as Taki Dent in Antalya, led by Dr. Sadık Taki, with the right materials documented and a clear maintenance plan, an All-on-6 is built to last.
