As far as dental implants go, titanium has long been the gold standard. The surface of the implant is without a doubt one of the most important when analyzing the aspects that can affect dental implant success in the long and short term.In this article, we discuss the significance of surfaces, compare various dental implant surfaces, and examine current anodized surface innovations for implants and abutments, including the Xeal and TiUltra surfaces.
Titanium may initially seem like an odd material for dental implants. Titanium is highly reactive in its pure condition despite having high strength, excellent biocompatibility, a low degree of potential toxicity, and a high resistance to corrosion. But when it comes into contact with oxygen, titanium oxide (TiO2) forms on the surface, stabilizing the area and facilitating osseointegration.
In terms of osseointegration healing time and, ultimately, implant treatment success, surface has a significant impact. Its chemical, physical, mechanical, and topographic surface qualities are all essential to optimizing the chances of effective osseointegration because it is the sole component of the implant that is exposed to the oral environment.
This knowledge gap was addressed in a 2018 study conducted by Professor Ann Wennerberg that included a comprehensive analysis of the long-term clinical outcomes of implant treatment with various surfaces. According to the study, anodized-surface implants had the highest survival rate (98.5%) after at least 10 years of follow-up.
Wennerberg compared the performance of implants with anodized, blasted, turned, titanium plasma-sprayed, sandblasted, and acid-etched surfaces and discovered that even for implants with older designs and surfaces, the mean marginal bone loss for all implant surface types in the study was less than 2 mm, well within what is regarded as an acceptable level.
Profs. Mattias Karl and Tomas Albrektsson examined results from 4,694 clinically assessed patients who received 12,803 anodized TiUnite implants reported in 106 studies in their 2017 study.Their findings support the remarkable low early failure rate and excellent long-term survival of implants with the anodized TiUnite surface. At the implant level, the estimated survival rate was over 99% after one year and 95.1% after ten years. TiUnite, one of the most clinically studied implant surfaces available, has demonstrated the capacity to improve osseointegration and preserve implant stability during the crucial healing phase. It can therefore play a crucial role in helping practitioners meet patient requests for a shorter time to get teeth.
Xeal is an abutment surface that is smooth, impermeable, and nanostructured. The foundation for long-term tissue health and stability is dense soft-tissue contact with an abutment, which can serve as a barrier to safeguard the underlying bone. In light of this, the surface chemistry and topography of Xeal were created to encourage soft tissue adhesion. Human gingival epithelial cells proliferate substantially more quickly on the Xeal surface than on abutments with a machined surface, according to clinical and non-clinical studies, and a randomized, controlled prospective clinical investigation found:
1.Considerably more keratinized mucosa
2.Significantly less bleeding of soft tissue after abutment removal
3.4* less bacteria
4.Stable levels of bone
