BACKGROUND: Contamination of implant abutments could potentially influence the peri-implant tissue inflammatory response. The aim of the present study is to assess the radiographic bone changes around customized, platform-switched abutments placed according to the "one-abutment-one-time" protocol, with and without plasma of @entity3503 cleaning treatment. METHODS: Thirty healthy @entity1 with thin gingival biotype (<1 mm) and history of @entity2520 received one maxillary implant each. Immediately before abutment connection, @entity1 were randomly assigned to control group (cleaning protocol by steaming) or test group (plasma of @entity3503 treatment). Outcome measures were: 1) success rate of implants and prostheses; 2) biologic and prosthetic complications; 3) peri-implant @entity604 ( @entity604 ); 4) esthetic and periodontal parameters; and 5) @entity1 satisfaction. RESULTS: Neither implants nor prostheses were lost in either group at the 5-year follow-up examination. Overall, both groups showed a slight amount of peri-implant @entity604 from baseline to 5 years. A statistically higher mean @entity604 was found in the control group compared with the test group at 6, 24, and 60 months after crown connection. Nevertheless, during the entire follow-up period, intragroup comparison demonstrated statistically significant mean @entity604 in the control group, but not in the test group. The test group showed a higher mean gain at the soft tissue margin, but not for the papilla. All implants showed good periodontal parameters, with no significant differences between groups. CONCLUSION: Plasma of @entity3503 could be used to disinfect implant abutments before insertion to minimize future peri-implant bone resorption.
