Abstract
Aim and purpose: The aim of this study was to analyse micromotion, presence of microgap and to evaluate, in vitro, the bacterial penetration through the implant-abutment interface of external hexagon, internal hexagon and morse taper connection, subjected to mechanical fatigue. A microgap has been described at the level of the implant-abutment connection. This microgap can be colonized by bacteria, and this fact could have relevance on the remodelling of the peri-implant crestal bone and on the long-term health of the peri-implant tissue. Dental implants like natural teeth can be affected by microorganism with the effect of peri-implantitis and peri-implant mucositis. Material and method: Multiples dental implants of external hexagon,internal hexagon, and morse taper connection, and their conical abutments with 10-years or longer follow-up times were found through a Pub Med, manual search and different international universities. Results: Presumably Morse cone connection implants showed the lowest count of microorganism, unlike external and internal hex implants showed a higher incidence of bacteria. Summary and conclusion: However, the pumping effect caused by the micromovements plays and important role for crestal bone resorption. Is ascerained that the bone is contaminated with the presence of the microorganism and with the liquid contained in dental implant?
