Notes on indication

As with all precision attachments, a stress-breakerwith an Interlock supporting groove acting as a coun-ter bearing must be incorporated when using theanchor-system with free-end restorations. As a pre-caution, a stress-breaker with an Interlock supportinggroove should also be included with boundedsaddles. This allows the primary situation of the den-ture to be integrated in the new design without anyalternation after loss of the distal abutment tooth.

Types of retention for the anchor-system Different threaded caps are available for screw

retention of the patrix:

cast-on threaded caps made from a highly wear-

resistant platinum-iridium alloy for one-piece

casting with the denture framework. Cast-on

threaded caps are the ideal retention option

with extremely difficult occlusal relationships and

for incorporation into metal occlusal surfaces.

dering on to the denture framework.

threaded caps with a retentive arm (titanium) for

providing retention in acrylic dentures.

palladium-silver alloy and titanium retention nuts

for a solder-free connection between the anchor

attachment and denture framework.

Standard versionfor normal to difficult

occlusal relationships.

Space required for the

matrix and patrix:

height 3.75 mm,

Ø 3.80 mm.

Micro versionfor extremely difficult

occlusal relationships.

Space required for the

matrix and patrix:

height 3.10 mm,

Ø 3.80 mm.

Generally a space (H)

of 4.5 mm between the

opposing dentition and

the alveolar ridge is

sufficient for the stan-

dard version (Fig. 2).

The proven Anchor-SystemVersions

With the micro version

a space (H) of 3.8 mm

is adequate. If this

space is not available,

the at-tachment should

be in corporated in a

metal occlusal surface.

The cast-on threaded

cap (Pt-Ir), which can

be cast on with both

CrCo and precious

metal, is ideal for use

with metal occlusal

surfaces for retaining

the attachment.

Connecting the crownand attachment matrixAttachment matrices

should always be placed

immediately above the

gingiva (0.5-1.0 mm)

and close to the crown.

At least two teeth

should be crowned and

Caution

To ensure the molten metal casts perfectly onto the Pt-Ir matrix, allow the mould to heat soak atthe final temperature for a minimum of 45 minutesduring preheating. The mould temperature with Pd-based- and non-precious metal alloys should beapprox. 920°C-940°C to prevent any temperatureloss during casting.

Adhere to the manufacturer’s subsequent heatingtimes following the preliminary preheat of the metal ingots, particularly with Pd-based alloys.

patrix analogue,Standard REF 7554 /Micro REF 6554, is

essential to ensure an

accurate casting. The

duplicating patrix ana-

logue and duplicating

coping of the threaded

cap have the same

shape of head and di-

mensions.

This guarantees pre-

cise positioning of the

threaded cap in the

duplicate mould during

investing and ensures

an accurate snap point

of the attachment after

casting.

During laboratory pro-

cedures always use the

patrix analogue, Standard REF 7551 /Micro REF 6551.

Do not exchange the

analogue for the origi-

nal patrix, Standard REF 0701 / Micro REF 0601,until the

denture is finished.

A cast-on platinum-

iridium threaded cap,

Standard REF 0713 /

Micro REF 0613, should

always be used to ensu-

re a homogeneous CrCo

or precious metal frame-

work casting. The com-

pact dimensions of the

threaded caps make

them ideal for incorpo-

ration in metal occlusal

surfaces. One-piece

casting with the denture

framework eliminates

the possibility of gap

corrosion.

Platinum-Iridium threaded capsPlatinum-Iridium threaded caps can be cast on with precious, Pd-based or non-precious metal alloy denture frameworks and are ideal for incorporation in metal occlusal surfaces.

To ensure an accurate

casting, the cast-on

threaded cap is sup-

plied fully assembled:

threaded cap (Pt-Ir)

with fitted brass dupli-

cating coping and in-

serted stainless steel

positioning screw.

The positioning screw

has been designed so

that it completely

covers the recess for

the attachment base

to prevent metal flow-

ing into the recess

during casting.

Caution

Before each try-in or final cementation the wholerestoration should be cleaned in accordance withcurrent hygiene regulations.

Before investingAfter removing the model from the duplicate mould,

place the cast-on threaded caps with the brass

duplicating copings in the impression of the patrix

analogue.

With reusable duplicating material the duplicating

coping should be placed in the recess without ap-

plying excessive pressure.

With silicone duplicating material we recommend

wetting the duplicating coping with grease or oil.

This raises the duplicating coping automatically to

the correct height if it has been pressed in too far.

material). Ensure that the reusable duplicating

material is not too old to prevent any inaccuracies

in the height.

The titanium retention nut REF 0707 and palla-

dium-silver retention nut REF 0708 are for use with

prosthetic restorations that require a solder-free

connection of the attachment or attachment holder

with the metal denture framework.

The palladium-silver nut is marked with a circumfer-

ential groove to distinguish it from the titanium

nut. The washers (accessories) made from non-resid-

ual burnout plastic are incorporated in the wax-up

of the metal denture framework and ensure a flat

surface between the patrix base and retention nut.

Technical data

Instruments and accessoriesThe following instruments and accessories are

essential to ensure correct preparation and accurate

results.

The duplicating patrix analogue, Standard REF 7552/ Micro REF 6552 (without a thread), is essential

for

duplicating. After preparing the metal denture frame-

work, insert the patrix analogue, Standard REF 7551 / Micro REF 6551.Do not exchange the analogue for the originalpatrix, Standard REF 0701 / Micro REF 0601,

until the denture is finished.

Fabricating a duplicate modelSoak the model in water at 40-50°C for 10 min-

utes. Then dab the model with a soft cloth and

duplicate immediately (with reusable duplicating

material). Ensure that the reusable duplicating

material is not too old to prevent any inaccuracies

in the height.

Fig. 57: Wax out under the attachment bar and matrix. Cover the bar

and matrix with a layer of wax approx. 0.10-0.15 mm thick

and then reduce until parallel.

Fig. 58: Insert the activated, cleaned duplicating patrix analogues into

the matrices. Ensure that the duplicating patrix analogues fit

flush on the matrices.

applied to the top of the washers. Wax up the metal denture

framework in the usual way.

Prepare the metal denture framework after casting. Ensure

that the washers cast in metal are not damaged when pre-

paring with a rotary cutter.

The fitting surfaces of the cast washers are waxed out during

polishing.

Fig. 65: After securing the nuts in position on the patrices, lift the

metal denture framework from the crowns and hold the patrix

with the exchange instrument REF 7452. Place the screwdriver

REF 7471 onto the nut and tighten fully to connect the

two components.

Fig. 64: Place the threaded nuts on the thread and screw them on

using the screwdriver REF 7471.

Fig. 66: If the height of the plastic washers has been altered due to

incorrect preparation or polishing of the washers, a spacer

REF 7553 or REF 6553 for regulating the snap point can be

inserted to restore the original snap point of the patrix.
