The document discusses the SilverPlug, a device designed to seal the screw tunnel of dental abutments in order to prevent bacterial colonization. It notes that bacteria can colonize the internal parts of dental implant components. The SilverPlug is customized to fill the space of the screw tunnel, leaving room for composite, and is inserted in a multi-step process to seal the tunnel and stop bacterial passage between implant components. Compared to other techniques, the SilverPlug provides an antibacterial seal that is easy to use and remove.

The bacterial contamination of dental
implants components
From the beginning of the
implantology era, the bacterial
colonization of the internal part of
the components was known and
investigated

The interconnections inside the
implants components
The areas marked in red are colonized by
bacteria
The area over the screw marked with a red
arrow is the one we are focusing with this
patent

4. 4
Clinical necessity
To fill the screw tunnel of the abutment with an antibacterial
device easy to use, easy to remove, to avoid the following
clinical problem:
Bacterial Colonization

5. 5
Biological response to bacteria
The biological response to
bacteria is inflammation and
bone resorption.
Bacterial Colonization

Bacterial Colonization
Mucositis Periimplantitis

7. 7
Bacterial Colonization
The volume of the implant tunnel
is similar of the volume of the
biggest parodontal pocket

8. 8
Bacterial Colonization
The parodontal
pathogenic bacteria
are implicated in
many deseases

We really want to
improve the risk

Which
Technique to
seal the
tunnel?

11. 11
Suggested techniques to seal “this area”
 Cotton pallet 35%
 Guttapercha 10%
 Wax 5%
 Teflon pallet 45%
 different 5%
+ composite
Hydrophilic
Halitosis
Difficult handling
Difficult removal
No antibacterial

2014
No device, specifically designed
to seal the Screw tunnel,
are available on the market

13. 13
Area of use
Implantology
Prothesis

14. 14
Who should use it and why ?
The General Dentist, the Specialist.
Because it seals, stopping the bacterial passage between the different
implant components, friendly to use easy to remove
It could become a Standard of care to seal the tunnel screw of the
abutment for each implant system

15. 15
This is the only instrument specificately
designed to seal the tunnel screw of
the abutment

16. The Silver Plug is customized to fill the space,
leaving enough space for the composite.
