Choosing a Dental Implant: Titanium, Zirconia, and Leading Systems

Titanium: the gold standard of implantology

Grade 4 and Grade 5 titanium (Ti Grade 4 and Ti-6Al-4V) has been the most widely used implant material for over 50 years. Its biocompatibility is backed by thousands of clinical studies, and titanium implant survival rates exceed 95% at the 10-year mark.

Key advantages of titanium:

• Excellent osseointegration — titanium naturally bonds with bone tissue.
• Mechanical strength — withstands occlusal forces, ideal for posterior regions.
• Long clinical track record — the best-documented implant material available.
• Surface treatments — modern techniques (SLA, SLActive, TiUnite) accelerate osseointegration.

Zirconia: next-generation aesthetics

Zirconia implants (zirconium dioxide, ZrO₂) are a relatively new option growing in popularity among patients who value maximum aesthetics and biocompatibility. Zirconia is white, eliminating the risk of a metallic shade showing through thin gingiva.

Key advantages of zirconia:

• White colour — no metallic show-through, ideal for the aesthetic zone.
• Hypoallergenic — zero risk of metal allergy.
• Low plaque adhesion — zirconia's smooth surface limits bacterial accumulation.
• Biocompatibility — excellent tissue tolerance.

Zirconia limitations: less flexibility than titanium (higher fracture risk under extreme loads), shorter clinical history, higher cost.

Comparison of leading implant systems

Straumann (Switzerland)

The global leader in implantology with over 60 years of experience. The flagship Straumann BLX line delivers immediate stability through innovative geometry. SLActive surface accelerates osseointegration to 3–4 weeks. The broadest scientific base of any system — over 900 published clinical studies.

Nobel Biocare (Sweden/USA)

A pioneer of modern implantology and creator of the All-on-4 concept. The NobelActive system provides excellent primary stability even in low-density bone. TiUnite surface (anodised titanium) promotes bone tissue attachment. An ideal option for complex full-arch rehabilitations.

MIS (Israel)

A system offering excellent value for money. The C1 and V3 lines deliver predictable clinical outcomes at a lower cost than Swiss systems. B+ surface (sandblasted and acid-etched) ensures good osseointegration. A popular choice for standard implant cases.

Osstem (South Korea)

One of the fastest-growing systems worldwide, with a strong presence in Asia and Europe. The TS III system features an innovative conical connection and a wide range of sizes. Highly competitive pricing with solid clinical results. A good choice for patients seeking an affordable solution from a reputable manufacturer.

Surface treatment: why it matters

The implant surface plays a critical role in the osseointegration process. Modern treatment techniques increase the micro- and nano-porosity of the surface, stimulating bone cell adhesion:

• SLA (Sand-blasted, Large-grit, Acid-etched) — Straumann standard, sandblasting + acid etching.
• SLActive — hydrophilic version of SLA, accelerates early osseointegration.
• TiUnite — Nobel Biocare anodised titanium, porous surface mimicking bone structure.
• RBM (Resorbable Blast Media) — sandblasting with resorbable material, used in MIS.

How to choose the right implant

Selecting an implant system should take several factors into account:

• Location — the aesthetic zone may require zirconia or a slim-profile implant.
• Bone quality — soft bone is better suited to aggressively threaded implants (Straumann BLX, NobelActive).
• Budget — premium systems (Straumann, Nobel) cost more but offer the longest warranties and clinical documentation.
• Allergies — patients with metal allergies should consider a zirconia implant.
• Case complexity — All-on-4 reconstructions require systems with a broad prosthetic ecosystem.
