Magnets have become very
popular as retainers for removable prosthesis overdentures for both root and implant
abutments. The advantages of magnetic retention over either bars or stud attachments are:
- No specific path of insertion is required (good for limited dexterity
patients)
- No abutment parallelism is required
- Soft tissue undercuts may be engaged
- Potentially pathologic lateral or rotating
forces are basically eliminated providing maximum abutment protection
|
| One word of warning
Magnets provide only retention-- not
prosthesis stability!
Prosthesis stability should be
achieved from denture base extension, other abutments like stud attachments, or
any combination of the above. |
|
|
The Shiner SR "Stress Resistant" Magnet system
allows free rotation
of the magnets in the housing, resulting in up to 24 degrees of
root or implant correction.
This movement between the magnet and housing permits non-destructive
movement of the prosthesis.
The rotation between the magnet and housing allows for constant
contact--and retention--between the magnet and keeper, even when the
prosthesis moves during function. |
 |
Both a regular and mini size magnet are available. The mini magnet is reduced in
size by 30% for when space is limited.
|
|
The regular magnets may be used with both the regular and mini
tooth pieces; the mini magnet may also be used with the regular and mini tooth pieces.
- Regular keeper: 4.0mm diameter, 6.9mm length.
- Mini keeper: 3.5mm diameter, 3.6mm length.
- Regular Magnet: 5.5mm diameter, 3.4mm vertical height.
- Mini Magnet: 3.9mm diameter, 2.4mm vertical height.

The neodymium rare earth II magnet has an indefinite life for long lasting retention. The
regular size magnet provides a minimum of 1.5 lbs of retention, and the mini system
provides a minimum of 1 lb of retention.
Both magnets are double encapsulated with a stainless steel material to eliminate
corrosion.

Design Solution
* No abutment parallelism required
* No path of
insertion/removal required
* Undercuts may be engaged
*No wear, no servicing requirements
* Overdentures may be root supported, or Implant supported |
The Shiner SR system provides ideal retention and abutment protection for maxillary and
mandibular overdentures. No abutment parallelism is required. The
prosthesis flange must be adapted to the ridge and undercut to ensure prosthesis stability.
The magnet system works especially well with implants as magnets control lateral
loading.

Shiner Magnet Instructions
It is important to note that not all magnets are alike
or equal. The Shiner Stress Directing Magnet system has no equal and is
patented generations ahead of other magnets. It is closed field to eliminate
external magnetic flux; is the ONLY dental magnet to be TOTALLY encapsulated
to prevent corrosion; provides an ideal 1.5 lbs of retention (1.0 lbs for
the mini); and freely rotates to permit nondestructive movement of the
prosthesis while providing constant retention.
The Shiner system is truly a
system utilizing a compliment of auxiliaries and tools to provide ease of
proper magnet to keeper alignment and contact. The system provides for
direct keeper placement in a root or incorporation into a cast coping. The system is also totally implant compatible.
