Ceramic Vs Metal Implants

One of the biggest advantages to zirconia ceramic implants over titanium metal implants is that they don t corrode or oxidize.

Ceramic vs metal implants.

Patients who underwent total hip arthroplasty with ceramic on polyethylene implants had a higher risk of revision compared with those who had metal on polyethylene implants according to results. For patients with less bone density or other issues two piece systems allow customization of the implant. Some patients may have an allergic reaction to titanium and ceramic implants are the only option. Titanium integrates with bone completely.

Low affinity for plaque. Titanium implants are more versatile than ceramic implants because they can be one piece or two piece systems. This microgap is in microns size and several in vitro studies tested the microleakage through the microgap and its effect on hard and soft tissues. Ceramic implants have been in use in the usa since 2009 and longer in many european countries but have not been in use for as long as titanium implants.

Ceramic implants are not a replacement for titanium implants but an excellent alternative in a range of cases. Ceramic implants can be crafted to match the colour of your natural teeth and lead to less mucosal discoloration than titanium. The prosthesis comprises a flat metal plate and stem which is inserted in the patient s tibia a polyethylene bearing surface as well as a contoured metal implant that is attached at the end of the femur bone. Uniquely they can meet the needs of a patient preference for 100 metal free materials with the esthetic reassurance of a white color.

Ceramic on polyethylene is currently the most popular hip replacement material representing 50 6 of all hip replacement cases back in 2014. The ceramic on metal implant did show less wear and friction than the all metal counterpart however. Patients understand the risks that metal joints and sockets bring to their long term health and are moving away from the material. It was proven that this gap acts as a reservoir for bacteria which induced peri implant tissue inflammatory reactions.

The flatter bearing of the knee replacement implant makes it less problematic than other implants including the hip implants. Pros of ceramic implants. It is biocompatible and creates a permanent bond. The existence of a microgap in two piece metal implant system has been well documented in the literature.

Metals corrode and although titanium and titanium alloys are corrosion resistant corrosion is a common occurrence when exposed in the oral cavity.
