Summary
Brief summary
The purpose of this study is to evaluate the treatment of periimplant infection (mucositis) with a follow up period of 3 months. Treatment will begin with professional mechanical cleaning around the implant in addition to home tooth-brushing twice daily for 4 weeks with antiseptic (chlorhexidine) gel or placebo gel. The placebo gel will be of the same appearance as the chlorhexidine gel. The gels will be in identical tubes with identical labelling except for individual subjects study numbers.
