Influence of Non-Thermal Atmospheric Pressure Plasma Treatment on Retentive Strength between Zirconia Crown and Titanium Implant Abutment
3-Methacryloxypropyltrimethoxysilane (M8550)
While the focus of many of the blog posts showing off the utility of UCT’s Specialty products has been on highly experimental publications, there are also many publications which test current commercial products partly composed of UCT chemicals. One such study was performed by the Lee group from the Pusan National University, South Korea. This group focused on studying the effects of a “non-thermal atmospheric pressure plasma” (NTP) treatment on the zirconia crowns and titanium implant abutments used in dentistry. Over time these implants tend to have complications in the form of fractures, abutment/screw loosening, or loss of retentive strength due to adhesive cement failure (aka, the crown or abutment falls off). The use of the NTP treatment was reported to strengthen the adhesive bond between zirconia crowns and certain resin cements, but there have not been studies performed on the retentive strength after surface treatment with a silane agent or MDP primer, both of which are widely used in the field of dentistry for commercial applications. In this case, the silane agent contains a solution of 3-Methacryloxypropyltrimethoxysilane, the same as UCT’s M8550. In the end, after a
thorough investigation, it was found that this NTP treatment had a negative impact on both the silane and MDP primer treated samples, and out of the two, the samples treated with MDP primer showed a higher retentive strength than the silane treated samples. As it goes with science, any result is a good result, even if the result means we’ve just found one more way how not to improve the characteristics of the product!
