Background Cementing dental restorations on implants poses the risk of undetected excess cement. Such cement remnants may favor the development of inflammation in the peri‐implant tissue. The effect of excess cement on the bacterial community is not yet known. The aim of this study was to analyze the effect of two different dental cements on the composition of the microbial peri‐implant community. Methods In a cohort of 38 patients, samples of the peri‐implant tissue were taken with paper points from one implant per patient. In 15 patients, the suprastructure had been cemented with a zinc oxide–eugenol cement (Temp Bond, TB ) and in 23 patients with a methacrylate cement (Premier Implant Cement, PIC ). The excess cement found as well as suppuration was documented. Subgingival samples of all patients were analyzed for taxonomic composition by means of 16S amplicon sequencing. Results None of the TB ‐cemented implants had excess cement or suppuration. In 14 (61%) of the PIC , excess cement was found. Suppuration was detected in 33% of the PIC implants without excess cement and in 100% of the PIC implants with excess cement. The taxonomic analysis of the microbial samples revealed an accumulation of oral pathogens in the PIC patients independent of the presence of excess cement. Significantly fewer oral pathogens occurred in patients with TB compared to patients with PIC . Conclusion Compared with TB , PIC favors the development of suppuration and the growth of periodontal pathogens.
