TiUnite is the Nobel Biocare proprietary titanium oxide dental implant surface that has clinically demonstrated the ability to increase the predictability and speed at which dental implants osseointegrate.^[1]

History and Purpose

TiUnite was first introduced to the market in 2000 by Nobel Biocare. TiUnite is a porous, moderately rough (Ra ~ 1.3 micrometer), titanium oxide (TiO2) surface manufactured through a spark anodization process. Spark anodization of titanium dental implants for structuring the surface with a porous and thick titanium oxide coating began in the early 1980s.^[2]

TiUnite has been proven to increase osseointegration (the process of the implant bonding to the jawbone)through numerous clinical studies. The clinical efficacy of TiUnite is supported by clinical data, with cumulative survival rates (CSR) in the upper ninetieth percentiles. Follow-up periods cover at least one year, with implants having been placed using both one-and two-stage surgical protocols:In a report published in 2007 by Glauser et al., five-year follow-up data of immediately loaded TiUnite implants in regions of predominantly soft bone confirms the long-term efficacy of TiUnite implants. In this publication, TiUnite implants demonstrated 97.1% CSR, with no drop in the stability over time.
