| Bar systems may be utilized for
overdentures, removable partial dentures, and implant prosthesis. Bars may be rigid or
resilient, permitting free movement of the prosthesis to direct forces away from the
retaining abutments to the supportive bone and tissue. Bar systems are generally in one of
three types: 1. Prefabricated ‘Dolder’ type
2. Plastic ‘Hader’ type
3. Round ‘Clip" bars and riders
The shape of the bar is indicated by the amount of room available,
by the shape of the alveolar ridge, and the type of construction. However, we recommend
the round plasti-wax bar, which may be more easily bent to follow the alveolar crest. Do
not engage labial soft tissue undercuts with the denture base flange, as this will alter
the path of insertion and cause excessive wear and servicing requirements.

Bar instructions
Reline/New Prosthesis using Delrin Analogue Instructions
Chairside Processing Instructions
The Preci-Horix, or Hader, bar and rider system
is the most popular of all bar systems due to its economy and simplicity.
The Hader bar is available as a burnout pattern in plastic and plastic wax,
and also in either palladium alloy or a yellow gold alloy.
The system allows the prosthesis to rotate
around the bar. The riders may be either the plastic rider or the precious
metal Ackermann clip. Another advantage is superior stability, retention,
and the option of abutment splinting. Recommended use is processing the
Horix Metal Housings into the denture using the Horix Processing Spacers,
and then using one of the three grips of plastic Horix clips in the metal
housings.
Relines or making a new prosthesis is made easy
by using the Horix White Delrin Analogues in the impression.

Preci-Bar (Dolder)
Preci Bar Instructions
The Preci (Dolder)
Bar is produced in a precious palladium alloy which is stronger, less
expensive, and has a higher fusing temperature than the traditional yellow
alloys or as a plastic wax casting pattern. The bar and sleeve attachment
are used for retaining removable partial dentures and overdentures.
The pear or oval shape is used for a
resilient prosthesis providing vertical or rotational movements. The 'U'
shape is for a rigid, or non- resilient, prosthesis. The dimensions on both
bars are 2.2mm height, and 50mm length. A larger size rigid Dolder bar is
available.

Ackermann Clips
Ackermann Clip
Technique
The Ackermann clip is an universal precious metal clip or
rider that will fit the Preci Horix/Hader, Preci Bar, or round bar. The Ackermann clip
features adjustable retention, easy patient insertion and removal, while requiring less
vertical space due to its horizontal retention tangs.
Due to its short (3.6mm) length, the sleeve
may be positioned on the bar even in a deep narrow trough. No soldering of
the clip is required. The horizontal retention tangs provide firm
retention in acrylic and require no additional vertical space.

The clip
features adjustable retention, easy patient insertion and removal, while requiring
less facial-lingual space due to its
occlusal retention tangs.
Do not
solder the clip. The occlusal retention tangs
provide firm retention in acrylic and require no additional vertical space.
Available in both gold and stainless.

Castable Bar Patterns--all shapes
The castable plastic and plasti-wax patterns
are available in profiles of the Hader and Round bars
to facilitate the use of non-precious alloys and direct casting.
The plastic wax burnout patterns are recommended when using
a fast burnout technique.
All are available in packages of 4
to facilitate the shaping and contouring of bars to the individual
anatomy.
The bars are approximately 6 cm long. The diameter
is 1.8 mm for Hader and round bars.

Horix/Hader metal housings
The thin (0.2mm) metal housings
are available for accurate seating of the plastic clips. These
are used in conjunction with the processing spacers on the model
to ensure an accurate seating of the clips. The advantages of
using the metal housings are easy insertion, removal, and replacement
of the clips without altering the prosthesis.

3 Grips of Hader Clips
Preat is proud to offer a new solution to past problems with
under sized or over polished bars. Now you may select from one of three grips of Hader
clips--the standard yellow, reduced retention white (also used for processing), and the
increased retention orange clips. When utilized with the metal housings, adjusting
retention for the patient is simple--remove the present clip and insert the proper
retention clip. Also, look for the word ‘HADER’ on the ends of the clips--it is
the only way to ensure you are getting the genuine Hader clips.
