Introduction:

peri-implant tissue health state is of vital importance in the success of implant-supported rehabilitation; for this reason, it is necessary to observe all those factors that contribute to maintaining this state, mainly oral hygiene.

Objective:

to determine the influence of oral hygiene on peri-implant tissue health status.

Methods:

a descriptive, observational and cross-sectional study was carried out in the Prosthesis service at the Dental Faculty of Villa Clara between 2017 and 2019. The universe of study consisted of 45 patients with implant-supported rehabilitations; the units of analysis were the implants and the tissues surrounding the 85 fixed prostheses performed on those patients who met the inclusion criteria. Clinical and radiographic observations were used, and a form was developed as an instrument. Oral hygiene and peri-implant tissue state were evaluated as the main variables. The information obtained was compiled in a database as well as processed and subjected to independence tests (the Chi-square statistic and its associated possibility) to show the relationship among the variables.

Results:

the analyzed variables showed a significant relationship between oral hygiene and the peri-implant tissue health status in favour of good hygiene and healthy tissues.

Conclusions:

the evidenced good oral hygiene contributed to the maintenance of healthy peri-implant tissues.
