What are zirconium/zirconia/ceramic dental implants?
Zirconium oxide
It is a metal oxide identified in 1789 by German Chemist Martin Heinrich Klaproth. zirconia is ivory in color making it almost like the colour of the natural tooth, which is vital for restoring teeth within the mouth especially within the anterior region. Additionally , its ability to transmit light makes zirconia an appropriate material for esthetics. zirconia implants have outstanding mechanical properties, good stability, a high biocompatibility and a high resistance to scratching and corrosion.
Properties
Zirconium oxide
- Good chemical and dimensional stability
- No effect of magnetic fields
- Mechanical strength and toughness almost like chrome steel alloys
- No cytotoxic effects on cells
- Poor chemical and electric conductor
- Low porosity
- High density
- High compressive strength.
What are the benefits of zirconia dental implants?
- Excellent esthetics as metal free
- Natural white color
- Biocompatible
- Preservation of bone
- Better gingival health
- Neutral
- First choice in patients with titanium allergy.
- Zirconia as biomaterial
Results on fibroblasts, lymphocytes, monocytes, macrophages, animal tissue , immunologic and bone tissues revealed that the varied sorts of zirconia tested on in vitro tissues don’t induce any adverse reaction or global toxic effects.
Microbiological analysis
The prevalence of cocci, few short rods, and no long rods on ZrO 2 surfaces were implicational an immature plaque which shows that early adhesion/colonization of bacteria on zirconia surfaces was significantly less compared to titanium, which proves that zirconia and its derivatives have the capacity to scale back plaque on implant and tissues, favoring better soft tissue healing and implant success at bone level.
Zirconia dental implants versus titanium dental implants
Titanium is considered the “gold standard” for implant materials. Numerous studies have affirmed the high success and survival rates of titanium implants in many various applications. One disadvantage is that it may result in poor esthetics, especially within the anterior region, thanks to its greyish color and exposure of the implant body due to soft tissue recession or if the individual has thin gingival biotype. Titanium and zirconium are the sole two elements that do not block dental implant from integrating into the bone. With regard to integration with the bone, zirconium implants appear to supply an equivalent success rates as titanium implants. Zirconium implants have a clear esthetic advantage over titanium implants being “pure white”, making them indistinguishable from natural teeth.
Conclusion
Titanium, as a biomaterial of choice, has been and remains largely employed in dental implantology. However, its corrosion products and individual sensitivities thereto are still controversial. Zirconia can prove a viable alternative in replacing titanium. A requirement for references concerning resistance to failure in long-term clinical trials is of paramount importance for zirconia implants. the sole thing that’s constant in life is change. When all restorations are changing to metal free, why should implants lag behind. For more details visit the site of DentCare Dental.
