Technical Manual - PREFABRICATED CASTABLE ATTACHMENTS AND IMPLANT COMPONENTS
WELCOME TO RHEIN83
Metalic spherical attachments have been in existence for many years. But these attachments were not widely accepted, by the dental
professionists. Then came the idea to render these mechanisms elastic! Smooth the head of the sphere and construct an elastic cap as a result
of these innovative changes this technique to day is amongst the most widely used. Rhein83 has been in business since 1983 and today these
products have been copied throughout the entire world, copies that in many cases reflect the forms of the objects but not the materials they
are made from, and therefore it significantly changes the functional result. Research is not only oriented towards the study of new products, but
also continually trying to perfect those that have been used for many years. Dental attachments are small mechanisms subjected to continuous
movement, stresses and oral changing, requiring periodic maintenance and revisions. Some products in this have been made for maintaining
and restoring the functionality, to all the prostheses, directly while they are in the mouth of the patients. The commitment of Rhein83 with its
knowledge and skills continually being enriched by the contributions of dentists and laboratory technicians, is to be able to improve the actual
standards and develop new products by means of original projects.

RHEIN83 - DESIGN AND FUNCTION

Rhein83 continues to manufacture female caps with elastic retention with the intention of eliminating as much vertical stress and trauma to
the restoration as possible. For Rhein83 the important thing is to make a system of components available to the dental technician and dentist
that will allow for the fabrication of a rigid, shock absorbing or resilient prosthesis. With the use of elastic retention, the function of Rhein83
attachments are extended.
With overdenture prosthetic devices or cases involving edentulous saddles, resiliency can be controlled with a wide range of retentive caps that
have various levels of elasticity and retention.

FUNCTIONAL CONCEPTS
TITANCAP
The TITAN cap is a nylon cap with an internal titanium ring

that has an oblique cut around the circumference, that makes
it elastic. It is able to pass, without any friction on the sphere,
leaving the perimeter smooth for a long time. The lifetime of
these caps is very long and they can be used with different
prostheses, even in cases where there is an imbalanced
prosthesis where the cap, made entirely from nylon produces
unsatisfactory results.

STAINLESS STEEL AND TITANIUM HOUSING FOR CAPS, PRE-FABRICATED, NORMAL AND MICRO SIZES
A. After a brief period of adjustment, the titanium ring

maintains a steady retention.
B. Over time, even with the wearing of the nylon, the titanium
ring maintains constant compression and retention
because it is enclosed between the titanium and the
housing.

Due to its lower radius, OT Equator is indicated to correct divergence up to 28 degrees between
implants without affecting the functionally of the elastic nylon cap.
Caps are available in a wide variety of retention levels.
ATTENTION; Where implant divergence exceed the maximum 28 degrees, Sphero Block and Sphero

The purpose of the OT Equator seeger system is to create a passive connection for
implant supported bars. The elastic seeger will correct small imperfections created by
the chairside impression technique or laboratory casting process. This reduces the risk
of the implant bar not seating passively.

OT Cap is a resilient distal extension attachment. It is indicated to be used with combined prostheses and removable
partial dentures.
For treatment plans that require a rigid substructure with milling and adequate counter attachments, OT Cap
functions as a stabilizing retentive connector. In addition, for treatment plans which require resiliency, OT Cap
provides a Cushion Effect similar to a shock absorber. This is achieved by the design of the sphere in conjunction
with the elastic retentive caps.
The OT Cap Tecno consists of a titanium sphere and ring that is incorporated into the nylon cap which has been
machined with a tolerance that assures high precision. While fabricating the prosthesis, the Tecno titanium sphere is
not exposed to any of the risks associated with the laboratory fabrication procedures and ceramic firing cycles.

OT Strategy from Rhein83 is a vertical micro-sized 1.8 mm castable sphere that is placed distally
on abutments for removable partials or utilized in implant bar combination case design. The male
component is designed with an additional support strut located under the sphere, increasing
strength and preventing rotation of the female cap during paralleling. The optional Steady, when
connected to OT Strategy, provides lateral stability without any additional milling.
OT Strategy caps are available for both duplication and fabrication using a stainless-steel housing
technique. Rhein83 caps are manufactured from an elastic material that increases the contact
zone with the sphere, giving mechanical and friction retention. Caps are color-coded indicating
five levels of retention. Tools for paralleling, inserting, and removing caps are available.

The Pivot Flex line of titanium posts was developed as an economical solution for direct in root
supported overdentures. The self-aligning Pivot Flex post features a rotating ball with a 2.5 mm
diameter and is indicated for divergent roots. When the posts are used with directional rings to align
retentive caps before the resin curing stage, the insertion of the denture is easy and trauma-free.
The Pivot Block line of milled titanium posts has a stationary ball and can be used for a temporary or
as a permanent solution. The Pivot Block titanium posts are available in 2.5 mm and 1.8 mm sphere
diameters. The Rhein83 elastic caps ensure optimal retention and function while minimizing wear.
There are five levels of retentive caps, including extra resilient caps for precarious root situations.
The levels of retention are identified by different colored caps.

A fracture is likely at the point where the overdenture attachments
are inserted in a prosthesis fabricated entirely of resin. With a
cast superstructure reinforcement, the denture will be less likely
to fracture. Fast and simple, the OT Box bar components are
used to fabricate the superstructure directly on the master model,
eliminating duplication and saving time. A non-precious or chrome
cobalt alloy is recommended for best results.
It is recommended that all nylon caps are inserted into a stainless
steel housing or cast reinforced frame. The stainless steel housing
offers a considerable advantage when the cap has to be removed
and replaced for routine maintenance or repositioned. Adjustments
or repairs can be performed chairside quickly and easily.

OT REVERSE 3 is a root supported direct pivot attachment system which provides retention and
stabillity for full dentures. The split male portion of the attachment is manufactured from titanium that
is embedded into a soft nylon material. The female pivots have a unique shape that is designed to fit
most remaining root structures. OT REVERSE 3 is successful even with minimal bone support of the
remaining dentition. The system is cost effective with simple laboratory and chairside procedures.

retentive clips. The vertical height of the attachment can be adjusted by reducing both male and
female parts from the original length of 5 mm down to 3.5 mm according to the pre-marked notches.
Reducing the vertical height creates no difference in functionality. Removal and replacement of clips
can be easily performed by the Dentist chairside.

ATTENTION
When shortening the OT VERTICAL attachment,
it is suggested that the clips not be reduced
more than 3.5 mm to prevent excessive
wear or failure. The limit is indicated by a
notch on both male attachments and clips.
REPLACEMENT OF RETENTIVE CAPS
Remove the clip using a flat round

instrument.
Once it has been removed, compare

the height of the old clip to the height
of the new clip.
If the clip needs to be reduced, use a rotary

instrument to shorten according to the notch
on the back.
Insert the new clip using the OT

VERTICAL insertion tool.
The attachment and the clip can be

mounted with its original height (5 mm)
or shortened (3.5 mm) by filing the side
opposite the hole.
Once the assembly and the wax model

have been completed, insert the ceramic
cylinder into the hole of the attachment
and cast.
After the attachment has been connected

with wax, insert the pin into the hole on
the top of the attachment. Rotate the pin
until a proper fit is obtained and it is easily
removed.
Sandblast the casting. Use a round bur

or apprpriate acid to remove any ceramic
materal that may be present in the hole.
Before duplicating the model, remove

the tip of the plastic pin that is located
on the end of the parallelometer key
mandrel from the rest of the shank.
Insert the pin into the hole of the

attachment and pour the duplicating
material (silicone or gelatin).

Normo/Micro
SPHERO FLEX - SPHERO BLOCK
In order to achieve a passive fit for the final prosthesis using the SPHERO FLEX
and SPHERO BLOCK attachment systems, it is necessary to use DIRECTIONAL
RINGS. When not used, there is a high possibility that the attachments will not
seat properly into the prosthesis due to incorrect positioning of the caps. This misalignment will result in premature wear of the caps causing additional trauma to
the implant. SELECTION OF DIRECTIONAL RINGS: The position and angulation
of the implant will determine which directional ring will be used. For parallel
implants, a 0 DIRECTIONAL RING can be used. For implants that have greater
divergence, a 7 or 14 ring can be used.
Place the DIRECTIONAL RING onto the hex of the attachment with the flat side
down. Be sure that the ring is fully seated. Next, place the retentive cap onto the
sphere and rotate the DIRECTIONAL RING until the cap is parallel with the other
caps and are in the same horizontal plane. Doing this ensures that the retentive
caps are correctly alligned inside of the final prosthesis.

Instructions for Use of

Abutment Driver / wrench
Abutment Driver has a sliding mechanism that locks it onto the ball abutment.
This needs to be fully engaged to properly tighten the abutment without
damaging the abutment. To dis-engage driver once the abutment is tightened
in the mouth push down on the silver portion to loosen the driver from the
abutment (Remember to tighten and loosen then tighten the abutment several
times to ensure the abutment threads are fully engaged in implant threading)
Think re-torquing your lug nuts. If tightened with a torque wrench or manual
electronics, it is recommended to use a value of 25Nm.

CUFF HEIGHT MEASURING TOOL FOR IMPLANTS

INSTRUCTIONS FOR USE
1. Rotate the gold colored plate until the tool is completely open.
2. Insert the tool into the implant. Be sure that it is fully seated on the top of the implant.
3. Firmly hold the tool and rotate the gold plate clockwise until it contacts the ridge.
Cuff Height Measuring Tool

With Stationary Pin
The cuff height measuring tool with stationary pin
provides the same functionality as the tool with a
threaded pin, however it is used in cases where there
is limited space between two implants.
4. Remove the tool and read the color coded rings indicated on the pin to determine the cuff
height.
NOTE:
When a colored ring is completely covered, and only the silver band between colors is
visible, it is recommended to utilize the next (higher) color.
IMPORTANT:
Before ordering an attachment, it is necessary to specify: Implant manufacturer, implant
brand, diameter, internal or external hex connection and cuff height. The cuff height is
determined by taking the corresponding color from the cuff height measuring tool. For
implants with an internal hex connection the cuff height will range from .5 mm to 7 mm
and for implants with an external hex connection, the cuff height will range from 1 mm to
7 mm.

BROKEN SCREW EXTRACTOR KIT FOR IMPLANTS
FOR REMOVAL OF BROKEN IMPLANT SCREWS
USING THE REVERSE CUTTING BUR TO EXTRACT A BROKEN SCREW

Place the reverse cutting bur into the angled handpiece and then insert it into the respective extractor. Before activating the
handpiece it is essential that the bur be in contact with the broken screw. Activate the handpiece in a counter clockwise
direction and be sure that firm downward pressure is maintained throughout the procedure. It is mandatory that
the handpiece motor be operated between 2000 rpm and 6000 rpm.To prevent the implant fixture from overheating, it is
necessary to move the reverse cutting bur in an up and down motion intermittently. Upon removing the broken screw, be
sure to clean the implant fixture thoroughly to remove any residual metal shavings that remain from the extraction procedure.
Operate at speeds not lower than 2000 rpm
NOTE: Before using, fill the bottom hole (side with the hex) of the centering device with petroleum jelly. In addition to
lubricating the device, in some cases, it will hold the broken screw in the extractor upon removal.
USING THE CLAW REAMER BUR WITH THE MANUAL CENTERING DEVICE

While holding the manual centering device firmly, insert the

device (A) into the fixture and make sure that the hexagon is
fully engaged into the implant fixture.
Insert the claw reamer bur (C) into positioner (B). Insert the bur into the
centering device until it comes into contact with the broken screw. Rotate
in a counter clockwise direction while maintaining constant downward
pressure. After a few turns the notch in the bur should reappear.
Manually remove the centering device which will contain the screw,
if not it will remain inside the implant and can easily be removed with
tweezers.
Fig.3
Fig.4
In certain cases, it may be easier to use the claw reamer bur

(C) with a right angle handpiece. With the motor stopped, insert
the claw reamer bur into the centering device (A) until the tip
touches the broken screw.
While applying pressure to the broken screw, start the motor in a

COUNTER CLOCKWISE direction at a low RPM. After a few turns the
notch in the bur should reappear. Manually remove the centering device
which will contain the screw, if not it will remain inside the implant and
can easily be removed with tweezers.
IMPORTANT: Please follow the instructions closely when using the Broken Screw Extractor Kit. Although the Reverse Cutting Bur has been hardened by a
tempering process, it should always remain vertical (parallel with the screw hole) during the procedure to prevent breakage. The Reverse Cutting Bur and
Claw Reamer Bur are subject to wear. These burs should be inspected for wear prior to each procedure and replaced if necessary. Finally, it is very important
that the motor direction is set to COUNTER CLOCKWISE when using this kit.
INSTRUCTIONS AND TECHNICAL ADVICE

REPLACEMENT OF CAPS
Rhein83 recommends that caps be replaced every 12 months. The longevity of the caps is affected
by many variables including: original case design, patient hygiene and general maintenance of the
prosthesis.
HOW TO REPLACE THE CAPS
In a prosthesis with metal housings, the cap can be removed by using a rotory instrument operated at
a low RPM. Be careful not to damage the metal housing during this procedure. The cap extractor tool
available from Rhein83 can also be used.
In a prosthesis where the cap is incorporated directly into the resin, it can be removed by hand with a
pointed instrument (such as a spatula) or the Rhein83 cap extractor tool. If a bur is used, be careful
to remove only the retentive cap and to not modify the form that remains in the resin. If the resin site is
damaged during the removal of the cap, repair the area with self curing resin before inserting the new
cap. The cap insertion tool is used for this procedure.
GREEN ELASTIC CAPS
These caps are highly elastic and have a medium level of retention. In cases where metal housings are
used, it is recommended to apply a drop of adhesive (cyanoacrylic) on the inside of the housing before
inserting the cap.
TITAN CAPS
These caps were designed to be used on the OT CAP TECNO as well as the Normal and Micro
attachments with machined titanium spheres.
CAP INSERTION TOOL
When using high retention caps, it is recommended to insert them directly chairside onto the attachment
using the cap insertion tool.
OTCAP Normal / Micro OT Reverse.
PROSTHESES WITH MULTIPLE ATTACHMENTS
In order to balance the retentive levels of a prosthesis with multiple attachments, it is possible to use caps with different levels
of retention in the final case design.
REAMERS AND CAP TESTERS: in a case where only caps with too high of a retention strength are available, insert the
reamer into the caps and rotate it in a clockwise direction, after only a few rotations it will wear down the perimeter which
will reduce the retention. Try the prosthesis in the mouth, if it is still too retentive, repeat the operation with the reamer, In
order to avoid trying the prosthesis in the mouth too many times, one can use the spherical tester, in order to evaluate
the holding strength.
HOW THE RETENTIVE CAP FUNCTIONS
The Rhein83 caps are manufactured with a high elasticity which creates both mechanical and frictional
retention resulting in a larger contact zone between the cap and the lower portion of the sphere. A small
space between the metal housing and the cap allows the cap to expand as it passes over the equator of
the sphere. Once completely engaged, the cap returns to its original form.
POLISHING OF THE CAST ATTACHMENTS:
It is recommended that only glass beads or a soft cloth wheel are used to polish attachments. In order
to avoid damage to the sphere duing these procedures, it is a good practice to cover the spheres with a
retentive cap. The retentive caps can be reused again for this procedure.
