IMPLANT DENTISTRY: MONITORING OF BACTERIA ALONG THE TRANSMUCOSAL PASSAGE OF THE HEALING SCREW IN ABSENCE OF FUNCTIONAL LOAD

Authors

Abstract

Purpose. To assess the changes in bacterial profile along the transmucosal path of healing screws placed immediately after insertion of two-piece endosseus implants during the 4-month osseointegration phase, in absence of functional load. Materials and methods. Two site-specific samples were collected at the peri-implant mucosa of the healing screws of 80 two-piece implants, for a total of 640 samples. Implants placement was performed following a single protocol with flapless technique, in order to limit bacterial contamination of the surgical site. Identical healing screws (5 mm diameter/4 mm height) were used for each of the 80 implants. During the 4 months of the study, the patients followed a standard oral care regimen with no special hygiene maneuvers at the collection sites. Results. The present research documents that during the 4-month period prior to application of function load the bacterial profile of all sites exhibited a clear prevalence of cocci at the interface between implant neck and osteoalveolar crest margin. Conclusions. A potentially pathogenic bacterial flora developed only along the peri-implant transmucosal path.
