TiUltra surface explained: what it is, how it differs from TiUnite, evidence

The TiUltra™ implant surface explained

A surface, not an implant system

TiUltra™ is the name of an implant surface, not an implant. It is an anodised titanium surface whose structure changes gradually from the top of the implant (smoother, near the gum) to the tip (rougher, in the bone), with a salt layer to keep it wettable until use.¹

In short

Cleared by FDA together with Xeal™ abutments in November 2020 (K202344).¹
Found on N1™, S Series, classic CC and NobelZygoma™ implants.²³⁴
Evolution of the older TiUnite® surface.¹
Long-term independent clinical data are still limited.

What "graded" means

Near the gum, a smoother surface is intended to be easier to keep clean; deeper in the bone, a rougher surface gives bone more to attach to. TiUltra™ changes gradually along the implant instead of having one texture everywhere.¹

What research shows so far

Regulatory record

The FDA summary for TiUltra implants describes an anodised surface whose properties change gradually from the collar to the apex, with a salt layer applied to preserve hydrophilicity (wettability). ¹

Surface properties describe the product; they do not by themselves prove better long-term results in patients.

Preclinical study

In an animal study (minipigs) with grafted bone defects, the anodised gradient surface and two sandblasted, acid-etched comparison surfaces showed no difference in the amount and height of new bone at 2 and 8 weeks. ⁵

Animal study with short healing times; results cannot be transferred directly to patients.

Its predecessor TiUnite® has a large body of long-term studies. For TiUltra™ itself, most published work is laboratory, animal or short-term.

Frequently asked questions

Is TiUltra an implant?

No. It is a surface available on several Nobel Biocare implants, such as the Nobel Biocare N1™ system and the S Series.³

Is TiUltra better than TiUnite?

There are no long-term head-to-head patient studies we could find. The manufacturer describes TiUltra as the evolution of TiUnite.
