Lack of keratinized tissue may be associated with a higher risk of peri-implantitis suggests a new study published in the Scientific Reports
This study aimed to investigate the effect of the lack of keratinized mucosa on the risk of peri-implantitis, while also accounting for possible confounding factors. A literature search was conducted in PubMed and Scopus, including human studies that assessed the presence and width of keratinized mucosa in relation to the occurrence of peri-implantitis. Twenty-two articles were included, and 16 cross-sectional studies we meta-analyzed.
The prevalence of peri-implantitis was 6.68–62.3% on patient-level and 4.5–58.1% on implant-level. The overall analysis indicated that the lack of keratinized mucosa was associated with a higher prevalence of peri-implantitis
Similar results were shown when subgroup analyses were performed, including studies with a similar case definition of peri-implantitis fixed prostheses only, patients under regular implant maintenance, and studies adjusting for other variables
Thus, the lack of keratinized mucosa is a risk factor that increases the prevalence of peri-implantitis and should be accounted for when placing dental implants.
