The purpose of this study is to examine the effect of the material to be filled in the access hole of the screw-retained implant prosthesis on the growth of bacteria and the simplicity of removal from the access hole.

A cotton ball is used as a material for filling the access hole, but there is a concern that bacteria may grow in the access hole. In recent years, a Teflon tape has been used in place of a cotton ball, and while having excellent sealing properties, it is disadvantageous that it is difficult to remove. Although Parafilm (trade name), a chemically stable paraffin thin film, is not used in the outpatient clinic, it is expected that it has excellent sealing properties and is easy to remove from its properties. It has not been studied whether these two materials (Teflon tape, parafilm) are superior to cotton balls. The purpose of this study is to compare the effect of the material filled in the access hole on the growth of bacteria and the ease of removal from the access hole.

When installing a screw-retained prosthesis in a subject with more than two implants, the researcher selects three access holes of equal diameter and length. Cotton ball is inserted into each access hole, and the upper portion is closed with a resin-based temporary sealing material (tempofill). After 2-3 weeks, the temporary sealing material is removed, and the material filled in the lower part is recovered, and immediately immersed in sterilized PBS.

Male and Female
Three or more implants (Bone Level manufactured by Straumann or Bone Level manufactured by Nobel) are inserted into the outpatient clinic of the University Dental Hospital, and a screw-retained prosthesis is attached and the material in the access hole is removed. Patients with material will remove the materials in the access hole after 2-3 weeks and who agree to be the subjects of this study.
