 |
Symptoms of wear at the stud of the VKS attachment lead to the loss of the function of the denture. Normally, the patient requires a new prosthetic supply which includes the risk that the root of the abutment tooth may be damaged considerably and can no longer be used to hold the denture. To avoid these risks and additional cost, the VKS stud reworking set has been developed. For
hygienic purposes, used instruments should not be reused; they must be disposed of. Use the VKS stud reworking set only for gold alloys. This kit allows the worn VKS patrix (stud) to be milled in the patient’s mouth to a cylindrical post over which a new titanium ball can be placed. |

Repair bur
|
|
Clamp the VKS repair bur into the angle
handpiece. Put the repair bur to the center of
the worn ball and hold it towards the same
direction as the ball is placed; only then
milling is started. Mill the residual stud parts
at a maximum speed of 5000 rpm until a
cylindrical post is obtained. |
|
|
|
Height Stop
|
|
The post that was produced with the repair bur
is shortened to a defined length using the
height stop. Clamp the height stop into the
angle and piece and place onto the cylindrical
post together with the guide sleeve. Shorten the
cylindrical post at a maximum speed of 5000 rpm
until the guide sleeve of the height stop rests
on the platform below the post. Adequate cooling
must be ensured by the operator. |
|
|
|
Tap for External Thread
|
|
Cut a thread on the cylindrical post. Add a
small drop of cooking oil onto the cylindrical
post and into the tap. Put the tap onto the
cylindrical post in the direction of insertion
and turn clockwise exerting slight pressure.
After the first turn the thread can be completed
without exerting any pressure to the tap. During
this process the tap is turned back by a half
turn after each full turn. This process is
repeated until the tap rests on the platform
below the cylindrical post. By turning
anticlockwise, the tap can be removed. Clean and
dry the thread. |
|
|
|
Glueing on the stud sleeve
|
|
Prior to gluing on the stud sleeve it must be
ensured that the thread post in the patient’s
mouth is grease-free and dry. Hold the stud
sleeve on the holding element, spread a small
quantity of adhesive in the internal thread of
the stud sleeve using a pointed object and screw
it on the threaded post. After the adhesive
hardens, the supporting post can be cut off with
a separating disc, the surface can be smoothed
with a rubber polisher and excess adhesive can
be removed with a pointed object. The surface of
the stud must not exhibit any scratches. |

INSTRUCTIONS FOR USE
VKS STUD REWORKING SET
Before using this product, please read and follow these
instructions carefully.
1. Indication Range
Removable dentures in conjunction with VKS Attachments.
The worn, ball-shaped part of the VKS Patrix is replaced
by a new titanium patrix.
2. Introductory Remark
Symptoms of wear at the stud of the VKS Attachments lead
to the loss of the function of the denture. Normally,
the patient requires a new prosthetic supply which
includes the risk that the root of the abutment tooth
may be damaged considerably and can no longer be used to
hold the denture. To avoid these risks and additional
cost, the VKS Stud Reworking Set has been developed.
Important: Generally, used instruments must not be
reused; they must be disposed off. Use the VKS Stud
Reworking Set only for gold alloys.
3. Processing
Mill the worn VKS Patrix (stud) in the patient's mouth
until a cylindrical post is obtained. The post must be
shortened to a precisely defined length. Cut a thread on
the post, screw on a titanium stud sleeve, and fix with
an adhesive.
3.1 Repaid Bur (1)
Clamp the VKS Repair Bur into the angle handpiece. Put
the repair bur to the center of the worn stud and hold
it towards the direction of insertion of the denture;
only then milling is started. Mill the residual stud
parts at a maximum speed of 5000 rpm until a cylindrical
post is obtained.
3.2 Height Stop (2)
The post that was produced with the repair bur is
shortened to a defined length using the height stop.
Clamp the height stop into the angle handpiece and place
onto the cylindrical post together with the guide
sleeve. Shorten the cylindrical post at a maximum speed
of 5000 rpm until the guide sleeve of the height stop
rests on the platform below the post. Adequate cooling
must be ensured by the operator.
3.3 Tap (3)
Cut a thread on the cylindrical post. Add a small drop
of oil onto the cylindrical post and into the tap. Put
the tap onto the cylindrical post in the direction of
insertion and turn clockwise exerting slight pressure.
After the first turn, the thread can be completed
without exerting any pressure to the tap. During this
process the tap is turned back by a half turn after each
full turn. This process is repeated until the tap rests
on the platform below the cylindrical post. By turning
counter-clockwise, the tap can be removed. Clean and dry
the thread.
3.4 Gluing on the Stud Sleeve (4)
Please note: Prior to gluing on the stud sleeve, it must
be ensured that the thread post in the patient's mouth
is grease-free and dry. Hold the stud sleeve on a
holding element, spread a small amount of adhesive in
the internal thread of the stud sleeve using a pointed
object and screw it on the threaded post. After
approximately 12 minutes, the supporting post can be cut
off with a separating disc; the surface must be smoothed
with a rubber polisher and excess adhesive can be
removed with a pointed object. The surface of the stud
must not exhibit any scratches. The gluing may only be
exposed to full stress after a minimum waiting time of 3
hours.
4. Assembly of the Matrix
In some cases, it might not be possible to place the
reworked stud in exactly the same position as the
original stud. To ensure proper function of the denture,
it may be required to remove the matrix housing from the
denture and to fix it anew in the patient's mouth
according to the changed position of the stud.
4.1 Resin Dentures
Remove the matrix housing from the denture resin by
milling and provide sufficient space to fix the matrix
housing in the patient's mouth again.
4.2 CoCr Dentures
Remove the cast matrix housing by milling and replace it
with a prefabricated metal housing. The matrix housing
can be fixed by gluing it to the CoCr object or by
polymerization of the CoCr denture.
4.3 Spacer Disc (5)
Position the spacer disc below the newly glued-on stud
and put on a metal matrix housing with a plastic matrix
being pressed in.
4.4 Fixing the Metal Matrix Housing
Try in the removable denture and check the correct fit.
If perfect fit is ensured, the metal matrix housing can
be fixed at the removable denture using a drop of cold
polymerizing agent.
Please note: No cold polymerizing agent or adhesive must
be added between the patrix and the matrix.
To provide additional safety, a thin layer of vaseline
should be applied onto the basal area below the metal
matrix housing.
4.5 Completion of the Denture
After fixing the metal matrix housing at the removable
denture, the spacer disc is removed and the function of
the denture is checked. Completion of the denture in
accordance with aesthetic aspects is carried out in the
dental technical laboratory.
Please note: The stability of the fixation types of the
VKS Stud Reworking Set is lower than the one of the
original fixation types. No forces should be formed by
rotation movements of the denture that affect the
reworked stud.
5. Safety Precautions
To avoid swallowing resp. aspiration various safety
precautions have to be taken, e.g. rubber dam and use of
dental floss for the auxiliary instruments. Safety
goggles must be worn to protect the eyes.
6. Other information
