A system, method and device design to prevent, treat and maintain dental periimplant infections including a dental implant to be inserted into a jawbone of a patient that includes a base segment provided at one distal end of the implant which is configured to be put inside and come in contact with the jawbone, an abutment portion provided on an end opposite to the one distal end of the implant to which an artificial tooth is configured to be attached, and a plurality of removable segments which are configured to be put inside and come in contact with the jawbone and are removably attached to the base segment. If an infection is diagnosed around an implant site, infected removable segments can be extracted while maintaining positioning of the uninfected removable segments and the base segment. The infected removable segments are replaced with cleaned or sterilized removable segments.
