- The most widely accepted material for achieving optimal osseointegration in dental implants is commercially pure titanium.
- This is because commercially pure titanium exhibits excellent biocompatibility, meaning it is well-tolerated by the body's tissues without eliciting an adverse immune response.
- Additionally, titanium forms a stable and strong oxide layer on its surface, which facilitates the direct bonding between the implant and the surrounding bone—a process known as osseointegration.

- Other materials, such as titanium alloys (e.g., Ti-6Al-4V), can offer increased mechanical strength but may have reduced biocompatibility compared to commercially pure titanium.
- While zirconia is a ceramic alternative with favorable esthetic properties and biocompatibility, it has not yet reached the same widespread acceptance or long-term clinical evidence as titanium.
- Stainless steel is generally not used for dental implants due to its inferior corrosion resistance and lower biocompatibility compared to titanium.

In summary, the key reasons why commercially pure titanium is considered the gold standard include:
- Excellent biocompatibility
- Corrosion resistance due to stable oxide layer
- Ability to achieve strong and direct osseointegration
- Long-term clinical success and evidence

Therefore, commercially pure titanium remains the preferred choice for dental implants to ensure optimal osseointegration and clinical outcomes.
