An Exploratory Clinical Investigation Evaluating Two Abutment Surfaces

"Immunological sample collection involves placing a Periopaper strip in the peri-implantar sulcus for 30 seconds. If sample is contaminated with blood, sample will be discarded and another sample will be collected (a different surface of the same implant/tooth can be used).~Microbiological sample collection involves collecting subgingival dental plaque by sliding the end of the STERILE curette (Gracey) inside the peri-implant sulcus. In case of slight bleeding following the first sample, dry the site again before collection. In case of profuse bleeding, collect a sample from another site (by site mean mesial/buccal/distal/lingual) of the same implant.~Both immunological and microbiological samples will be sent for respective laboratories for the analysis.~Clinical evaluation will assess presence of dental plaque, bleeding on probing and gingival status."
