This study aimed to investigate the presence of microorganisms in the
inner thread of the fixture (endosteal implant part) of the Brinemark(
TM) system. In 9 volunteers the apical part of 2 abutment screws that
had been in place for 3 months was examined by means of differential p
hase-contrast microscopy. All screws harboured a significant quantity
of microorganisms, mainly coccoid cells (86.2%) and nonmotile rods (12
.3%). Motile organisms (1.3%) or spirochetes (0.1%) were only sporadic
ally registered. A microbial leakage at the abutment/fixture interface
probably is the most probable origin for this contamination.
