Implant dentistry enters new era with launch of Xeal™ and TiUltra™ surfaces from Nobel Biocare

Nobel Biocare is inviting dental professionals to join the Mucointegration™ era with the launch of the Xeal and TiUltra surfaces. Applied to not only implants but also abutments, these new surfaces were created to optimize tissue integration at every level for the purpose of improved implant treatment outcomes.

Based on its decades-long expertise in applied anodization technology, Nobel Biocare has understood that for optimal integration of dental implant restorations, different tissues demand different surfaces. While osseointegration is fundamental for the long-term function of implant restorations, soft-tissue integration is often overlooked. Dense soft-tissue contact with the abutment, however, can act as a barrier to protect the underlying bone.1,2,3,4 To maintain long-term tissue health and stability, surface chemistry as well as topography of the new Xeal abutment was specially designed to facilitate soft-tissue attachment to the abutment. Backed by data from a clinical study with two-years' follow-up, the Xeal surface has demonstrated a significant increase in soft-tissue height compared to machined abutment surfaces.5 It will be made available for the On1 Base and Multi-unit from Nobel Biocare.

Developed with the ultimate goal of early osseointegration and long-term bone stability in mind, the ultra-hydrophilic, multi-zone implant surface, TiUltra, is taking anodization technology a step further. Going beyond just roughness, the surface chemistry was optimized with the goal to positively influence its interaction with cells and ultimately osseointegration. TiUltra's topography has also been reimagined to gradually change from a minimally rough and non-porous collar to a moderately rough and porous implant apex, thus respecting the natural transition from hard, dense cortical bone to cancellous bone.6

The TiUltra surface will be available with Nobel Biocare's NobelActive and NobelParallel Conical Connection implants. Combined with the Xeal abutment surface, dental professionals have a new complete solution for soft-tissue health, bone protection and fast osseointegration at their disposal. To ensure that every implant and abutment is delivered in pristine condition, the surface chemistry and hydrophilicity of both Xeal and TiUltra is preserved with a protective layer that dissolves upon contact with fluids.

"Having mastered osseointegration for decades, Nobel Biocare is taking tissue integration to a new level. With the launch of Xeal and TiUltra, we are not only advancing our leadership position in surface technology but also opening a new era for implant dentistry, that of Mucointegration," said Hans Geiselhöringer, President of Nobel Biocare. "Our focus has always been on the patient. These new solutions are supported by clinical evidence including a two-year clinical trial."
