Abstract:

Aim & purpose: The aim of this study was to analyze 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 remodeling 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 periimplant mucositis. Material & 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 & Conclusion: However, the pumping effect caused by the micro-movements plays an important role for crestal bone resorption is ascertained that the bone is contaminated with the presence of the microorganism and with the liquid contained in dental implant.
