UNASSIGNED: Abstract The aim of this study was to test if stress on the prosthetic connection during insertion maneuvers can induce micro-warping at the implant-connection. From Sept 2011 to July 20134, @entity1 with implants loaded at least 5 years that were placed with two different insertion implant mounters - @entity2468 (conventional) and ME (mountless) - were selected from all those that had received dental implant therapy in the past and coming to routine check-up or spontaneous visits during the study period. @entity1 having implants loaded at least 5 years that were placed with two different insertion implant mounters - @entity2468 (conventional) and ME (mountless) - were recruited. Samples were obtained from inside the connection and the abutment surface (CIAS) using absorbent sterile paper tips. qRT-PCR was performed for total bacterial counts and loads of @entity3841 (Aa), @entity2523 (Pg), @entity3289 (Tf), @entity14148 (Td), @entity3288 (Pi), Peptostreptococcus micros (Pm), @entity8209 (Fn), Campylobacter rectus (Cr), @entity4424 (Ec), and @entity5132 (Ca). The ANOVA test was used to test for differences. Nine @entity1 (20 implants, @entity2468 group) and 5 @entity1 (10 implants, ME group) were included. Regarding the red complex, Tf was seen in 80% and 30% of @entity2468 and ME implants respectively (p<0.001). Significant differences were also found in microbial load. For Td, proportions were 45% vs. 10% (p=0.022) with no significant differences at load levels. Regarding the orange complex, higher prevalence values were found in @entity2468 implants, although differences were non-significant. Microbial load levels for orange complex bacteria were higher for @entity2468 than ME, being these differences statistically significant for Fn (4.94 vs 3.09; p=0.001). Finally, Ec was only detected in the @entity2468 group, and Ca and Aa were not found in either group. Within its limitation (small sample size, retrospective analysis, indirect measurement method), the present study suggest that aA mounter not impacting on the prosthetic connection should be used to reduce microbial contamination of implants.
