Summary

Contamination of implant abutments could potentially influence the peri-implant tissue inflammatory response. The aim of the present study was 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 argon cleaning treatment.

Eligibility Criteria

Inclusion Criteria

Patients aged 18 years or older, previously treated for periodontal disease according to a comprehensive treatment strategy,25 requiring a single implant-supported restoration in the anterior maxilla or premolar region with the presence of mesial and distal tooth.
Bone crest allowing the insertion of a 4 mm platform implant without further bone augmentation procedures and with thin (≤ 1 mm) gingival biotype, measured by previously reported protocol.

Exclusion Criteria

no relevant medical conditions;
non-smoker or smoking ≤ 10 cigarettes/day;
plaque Index and bleeding on probing ≤ 25 %;
impossibility of follow-up for 5 years after prosthetic loading;
pregnant and lactating patients;
patients with a history of bisphosphonate therapy;
presence of sites with acute infections.
