Evaluating the efficacy of implant sealant at implant abutment interface - a microbiological study

â–ª         Dental implantology is the fastest developing technology in the practice of dentistry today which provides a natural looking appearance and has opened the door to the 21st century in dentistry.

â–ª         Implant superstructures are the superior part of a fixed or a removable prosthesis that includes the replacement teeth and associated gingival/alveolar structures.

It has been postulated that a potential microscopic gap of 55–104 μ exists at the implant-abutment interface or the implant superstructure interface.

â–ª          Oral micro-organisms have a diameter of 10 microns and can easily pass through this micro gap. This misfit may lead to microleakage of fluids and lead to bacterial growth which may cause loss of marginal bone and may lead to periimplantitis..

â–ª          Thus, this study is formulated to check how effective is the presealing done at the implant interface by measuring colony forming units (CFU) of Preprohormones Gingivalis (PG), Prevotella intermedia(PI), Aggregetibacter actinomycetemcomitans (Aa).

ROLE OF IMPLANT SEALANT IN CONTROLLING MICROLEAKAGE

•      Implant sealant provides a reliable seal and fills the hollow spaces in the implants .

•      It is a highly viscous silicon matrix which ensures a reliable sealing and prevents the ingression of organisms.

•      The principle of this material is that as the place is already occupied, there will be no nutrition for vital activity of organism to grow and develop.

â–ª         The addition of thymol ensures better Antifungal and antibacterial activity.

â–ª         The material does not get dried off, maintaining its viscosity, and preventing formation of new micro gaps.

â–ª         gaps.

â–ª         Thin silicone film effectively prevents adhesion of plaques on supporting implants. .

The leakage without sealing agent was probably due to lack of complete wall to wall adaptation between abutment and implant.
