Zirconia dental implants are a metal-free treatment. As a result, they look more natural and are less likely to cause a reaction in the body.
A recent systematic review and meta-analysis of preclinical studies [70] indicated that one-piece zirconia implants have similar clinical outcomes to florida zirconia implants. This includes BIC, removal torque and push-in strength.
1. Aesthetics
Zirconia is metal-free and may be a good choice for patients who have a history of nickel allergies. It is also more attractive than titanium.
Titanium implants are known to last 20 years or more, but zirconia implants have only been used for a few years, so long-term data is not available.
One-piece zirconia implants have shown high survival rates and a low marginal bone loss in most studies. The exception was the study by Cannizzaro et al. [27] which included both occlusal and non-occlusal loading protocols, resulting in lower survival rates.
Two-piece zirconia implants have been reported to have a higher failure rate. The most common causes of early failure were fractures and peri-implantitis. This could be due to the fact that they are more difficult to place surgically, as they are a single unit with abutment.
2. Biocompatibility
Zirconia is a popular material for dental crowns because of its resemblance to diamond. It is also a great option for those with metal allergies because it is completely inert.
Unlike titanium implants, ceramic implants promote bone growth and do not interfere with the body’s natural healing processes. They are also more durable than titanium, meaning they can withstand increased biting forces for a longer period of time.
Laboratory biomechanical tests may be useful for evaluating stability and other physical characteristics of an implant, but clinical investigations are the ultimate proof that a device is successful. Pieralli and colleagues reviewed systematic reviews with meta-analysis that included investigations that matched certain inclusion criteria to evaluate the clinical success of one-piece zirconia implants. Their results demonstrated comparable osseointegration rates as compared with titanium implants.
3. Strength
Zirconia implants are not as strong as titanium, but they are still strong enough to withstand the forces that teeth and gums are exposed to. This makes them a great choice for restoring the backmost molars, which can exert excessive chewing forces that could damage other implant materials.
Zirconium has a very smooth surface, so plaque has a hard time adhering to it, which can lower the risk of peri-implant diseases. Zirconia is also a non-metal, which means it doesn’t conduct electricity or heat.
Zirconia implants are still relatively new, so clinical studies about their long-term performance and success are limited. But they show promising results so far. The survival rate and marginal bone loss of one-piece zirconia implants are comparable to that of titanium implants.
4. Corrosion
Zirconia is not a metal, and therefore does not cause any negative reaction with your body. This makes it a good option for people with metal allergies or sensitivities.
Zirconium is also non-conductive, meaning that it does not conduct electricity or heat. This means that it will not react with the tissues around it, unlike titanium which can cause inflammation and bacteria buildup.
In addition, ceramic implants have a one-piece design, so they do not create an opening like titanium does. This prevents the accumulation of bacteria that can lead to peri-implantitis, bone loss, and other complications.
Zirconia implants have a high rate of osseointegration, which is measured by bone-to-implant contact. This means that they will bond with your jawbone and stay secure over time.
5. Cost
Both zirconia and titanium implants are able to fuse with the jawbone, through a process called osseointegration, in order to perform the same function as natural tooth roots. Zirconia implants are non-corrosive, meaning they can remain in the mouth without fear of damage or infection.
Additionally, studies have shown that they may be less prone to bacteria accumulation around the implant. This could result in a reduced risk of https://adwcenter.com/, as found by Mate-Sanchez de Val and Siewert [70].
Conclusion
Zirconia implants have been used in Europe for years, but are newer to the US dental market. For this reason, it’s important to find a dentist who specializes in zirconia implants and can offer the correct care and support for them. This can include MELISA testing to check for any allergies.
