TiUltra
Also known as: TiUltra surface, Nobel Biocare TiUltra
Nobel Biocare’s multi-zone anodised implant surface, in which the roughness changes gradually along the fixture from a minimally rough collar to a moderately rough apex.
Key facts
| Manufacturer | Nobel Biocare Services AGVerified spec[1] |
|---|---|
| Production process | Produced by anodisation, and described by Nobel Biocare as an ultra-hydrophilic surface.Manufacturer-reported[2][3] |
| Topography | Nobel Biocare states that "the topography of the TiUltra ultra-hydrophilic surface gradually changes, from a non-porous and minimally rough surface at the coronal part of implant to a moderately rough surface at the apical part", and describes it as a hybrid design with a gradual change in roughness in the intrabony zone.Manufacturer-reported[2] |
| Surface roughness | Roughness reported by Nobel Biocare as approximately 0.5 micrometres at the collar rising to about 1.4 micrometres at the apex.Manufacturer-reported[3] |
| Surface category | Spans the minimally rough and moderately rough bands by design rather than sitting in one of them.Manufacturer-reported[2][3] |
| Geographic availability | Listed in Nobel Biocare’s implant catalogue as one of its two surface options, alongside TiUnite.Manufacturer-reported[1] |
| Predecessor system | Nobel Biocare presents TiUltra as the successor generation to its anodised TiUnite surface.Manufacturer-reported[2] |
Overview
TiUltra’s distinguishing idea is that an implant does not meet the same tissue along its whole length, so it should not present the same surface along its whole length. The collar sits where soft tissue and the crest of the bone are, and is finished smooth and non-porous; the apex sits deep in cancellous bone, and is finished moderately rough. Nobel Biocare’s published figures put the range at roughly 0.5 micrometres at the top to 1.4 at the bottom, with a gradual transition rather than a step. This is a genuine design departure rather than a renaming, and it is the reason the product cannot be summarised by a single roughness number in the way a conventional surface can. Whether zoning produces better clinical outcomes than a uniform moderately rough surface is a separate question, and the manufacturer’s own material is the main published source on the design at present.
