Fatigue tests of the metal-to-metal adhesive bond used in dental implantology including adhesive drying time

Abstract

Fatigue tests carried out on the dental implant experimental adhesive connection proved that the adhesive drying time is one of the factors responsible for adhesive higher durability. So far this factor has not been taken into account during experimental studies. Specimens of adhesive connection with RelyX dental adhesive were allowed to dry for 1, 3 and 8 days. After each drying time the fatigue tests were carried out. As the adhesive drying time increased, its durability also increased. After 3 days of drying, the adhesive durability were twice higher than the adhesive durability with 1 day of drying. Specimens with 8 days adhesive drying revealed the unlimited durability for load level applied during the study. Research has shown that the drying time of the adhesive is an important factor that has so far been neglected. Allowing the adhesive to dry for at least 3 days increases the chances of successful implant treatment. The frequency with which the test was carried out was set at f = 1Hz. The abutment roughness were measured with the MarSurf PS 10 measuring device with the average roughness Ra was 1.8 µm. The metal surface prepared in this way bonds better with the dental adhesive.
