Abstract

Objective: To determine if there is a relationship between the height of peri-implant tissues and subgingival bacterial infiltration of resin provisionals on implants. 

Materials and methods: Design: exploratory, descriptive, and cross-sectional. Participants: patients treated at the Dental Clinic of Andres Bello University during September and October 2022. Twenty-two provisional crowns on titanium implants were analyzed before the placement of the definitive crown. These crowns were exposed to the oral environment of the patients for 3 months and without active periodontal disease. Method: Initially, the gingival margin limit on the provisional was marked with a graphite pencil. Once the provisional was removed, the height of the keratinized gingiva was measured using a North Carolina periodontal probe from the free margin to the implant platform. Subsequently, each provisional was immersed in a solution of crystal violet for 5 minutes to observe the percentage of bacterial infiltration to relate it to the height of the keratinized gingiva at each site. 

Results: There is a strong correlation between the variables studied; the test results indicated that a higher height of keratinized gingiva results in a lower percentage of bacterial infiltration. 

Conclusions: As the height of the keratinized gingiva increases, the degree of subgingival bacterial infiltration in provisionals on implants decreases.
