Parvini P, et al. - Via examining 65 patients, researchers compared discomfort/pain following periodontal probing around teeth and peri-implant probing around implants with or without platform switching. Only 2 types of implants were included in this analysis: one with and one without platform switching. Investigators found that peri-implant probing resulted in significantly greater discomfort/pain than periodontal probing. Implant design with/without platform switching was not significantly affected by discomfort/pain.
