Design forms of all cases of RPD using attachments or implants



Case Design #1
1
Bilateral Free-End Distal ExtensionBilateral free-end distal extension partial dentures are most
commonly restored with resilient function attachments when
opposing natural teeth or fixed bridgework. Solid function
attachments are indicated when opposing a removable partial
or full denture. Milled lingual arms arm recommended with
solid function attachments. Double abutting is always recommended
when possible, especially when using solid function
attachments. Leave rugae open for comfort when possible.

2
Option #1 Extracoronal Resilient
or Solid
Indirect retention should be added for attachments such as
the ORS-DE or SA Anchor/Ceka, etc. Attachments such as
the Dalbo and ASC 52 have built-in indirect retention. Milled
linguals are recommended for solid/rigid attachments such as
the D 2.7, Strategy, Vario, etc.
Resilient Attachments: Dalbo or Swiss Mini, ASC 52, Swiss
Anchor, ORS-DE, Zaag RPD.
Solid Attachments: D 2.7, Strategy, Vario SG, Swiss-EX,


3
Option #2 Intracoronal SolidRemovable Partial Denture with double abutted crowns on
#6-7 and 10-11. Milled lingual arms are recommended for stability,
retention and support. A cylinder type attachment such
as the Omega-M maybe placed interproximal between 6-7
and 10-11. The male of the Omega-M attachment becomes
part of the removable milled lingual arm.
Attachments Indicated: Score PD, PT Snap, Biloc,
McCollum

4
Option #3 Implant BridgesBridges may be cemented over titanium post abutments or
retained with set screws. Angled Titanium Abutments may be
needed for divergent implants. Bridges may also be screw
retained using direct UCLA abutments. Hexed UCLA
Abutments may be used to make custom angled abutments.
The Score-UP placed intracoronally into #6 & #11 with or without
the U-Pin.
Implant Components: Titanium Abutment Posts Straight or
angled, UCLA Abutments, non-hexed for bridges and hexed
for custom angled abutments.
Attachments: Set Screws, Score-UP

Case Design #2
5
Unilateral EdentulousThe unilaterally edentulous arch is a common situation with
special concerns. Cross stabilization with clasps or attachments
is required when restoring more than a three-tooth
span. For unilateral removable partials without cross arch stabilization
see Case #110. Two abutments should be splinted
when possible. Milled lingual arms are recommended when
using intracoronal attachments or solid function extracoronal
attachments.

6
Option #1 Extracoronal ResilientRemovable Unilateral Partial Denture with double abutted
crowns on #10 & 11 and cross arch stabilized between #3 &
#4 with a Cross Arch Roach attachment. A resilient attachment
such as the ASC 52 or Mini Dalbo is placed on the distal
of #27. Milled lingual arms are contraindicated for resilient
designs. For comfort we recommend an open rugae on maxillary
restorations when possible.
Attachments Indicated: ASC 52, Mini Dalbo, SA Anchor, etc
on distal. Cross Arch Roach interproximal of #3 & #4.

7
Option #2 Intracoronal SolidRemovable Unilateral Partial Denture with double abutted
crowns on # 10 & #11 and cross arch stabilized with an
attachment such as the Biloc or Omega-M between #3 & #4.
Milled linguals are recommended on the abutments. For comfort
we recommend an open rugae on maxillary restorations.
Attachments Indicated: Score-PD, Biloc, PT-Snap,
McCollum, etc. For additional stability the Omega-M may be
placed interproximal. For cross arch stabilization you may
select the Biloc, Pt-Snap, McCollum etc.



8
Option #3 Implant BridgesBridges may be cemented over titanium post abutments or
retained with set screws. Angled Titanium Abutments may be
needed for divergent implants. Bridges may also be screw
retained using direct UCLA abutments. Hexed UCLA
Abutments may be used to make custom angled abutments.
The Score-UP placed intracoronally into #6 & #11 with or without
the U-Pin.
Implant Components: Titanium Abutment Posts Straight or
angled, UCLA Abutments, non-hexed for bridges and hexed
for custom angled abutments.
Attachments: Set Screws, Score U-P

Case Design #3

9
Posterior Unilateral ToothborneRestorative options for this partially edentulous situation
include a one-piece bridge, segmented bridge, implant bridge,
implant single units or a removable partial denture. If abutments
are not parallel or if the posterior abutment is questionable
a segmented bridge with an intracoronal attachment
is indicated. In cases with severe tissue defect a removable
partial denture may be indicated.

10
Option #1 IntracoronalFixed bridge with divergent preparations. Intracoronal attachment
placed on distal of #6 with the possibility to convert easily
to a partial denture if the molars fail. An attachment such
as the Score BR or Score U-P is easily converted for this
purpose.
Attachments Indicated: Score-BR, Score U-P, PDC,
Beyeler, Biloc, Strauss Micro, McCollum, etc.

11
Option #2 Extracoronal Screw
Retained
Telescopic operator removable bridge with a cemented crown
on #6 with an extracoronal screw type attachment such as the
ScrewBloc or SwissBloc. A telescopic coping on #3 may also
be made incorporating a tube from the Tube & Screw
Attachment. The pontics would be attached to the telescopic
crown on #3.
Attachments Indicated: ScrewBloc, SwissBloc, Fletcher
Bloc, T-Bloc, etc. Tube & Screw Attachment.

12
Option #3 Implant BridgesSingle or splinted implant crowns over Titanium Abutment
Posts may be cemented or retained with Set Screws. Angled
Titanium abutments may be necessary for divergent implants.
Screw retained single units or custom angled abutments may
be made with the hexed UCLA cylinders. Non-hexed UCLA
cylinders are used for bridges.
Implant Components: Titanium straight or angled abutment
posts, UCLA hex type abutments for single units or custom
angled abutments. Non-hexed UCLA Abutments for splinted
crowns.
Attachments Indicated: Set Screws.

Case Design #4
13
Bilateral ToothborneRestorative options for this partially edentulous situation
include one-piece bridges, segmented bridges, implant
bridges, implant single units or a removable partial denture. If
abutments are not parallel or if the posterior abutments are
questionable, segmented bridges with intracoronal attachments
are indicated.

14
Option #1 Intracoronal SolidFixed segmented bridges with Score-UP attachments in #22
& #27. If the posterior abutments are lost in the future, a
removable partial denture may be constructed. If #31 is questionable,
a Cross Arch Roach may be placed into #20 for
future resilient partial denture or a Biloc may be placed into
#20 for future solid function partial denture.
Attachments Indicated: Score-UP on #22 & #27. A Cross
Arch Roach or Biloc into #20 pontic.

15
Option #2 ExtracoronalRemovable partial denture with solid or resilient attachments.
While solid function attachments are most commonly used in
this situation, resilient attachments may be selected if posterior
abutments are questionable. This would allow for conversion
to resilient function. The lingual arms on the partial denture
would have to be removed to allow resilient function.
Attachments Solid: D 2.7, Swiss-EX, Bredent, Strategy
Attachments Resilient: Dalbo or Swiss Mini, ASC 52,ORS -
DE

16
Option #3 Implant BridgesA Titanium Abutment Post may be placed onto #20 implant
and splinted to #22 via a Score-BR or Score-UP. The implant
crown may be cemented or retained with a lingual Set Screw.
The #20 implant bridge may also be restored with a nonhexed
UCLA Abutment and Screw. Implants #27-#30 may be
restored with Titanium Posts or UCLA abutments. Angled
abutments may be necessary for divergent implants.
Implant Components: Titanium Abutment Posts, UCLA
Abutments
Attachments: Score UP or Score BR, Swiss Set Screw


Case Design #5
17
Anterior ToothborneSince 5 teeth are missing in this example, a patient removable
restoration is recommended. If restored with implants, a
cemented or screw retained bridge may be fabricated, except
in cases with severe bone loss where a removable implant
restoration would be indicated. Palatal coverage for a removable
partial denture may be avoided with attachments placed
mesially inconjuction with milled lingual arms for stability.

19
Option #1 IntracoronalRemovable Partial Denture with double abutted crowns on
#5-6 and #12-13. Intracoronal attachments are placed mesially
with milled linguals. A cylinder type attachment such as the
Omega-M may be placed interproximal between #5-6 and
#12-13. If possible, do not cover the rugae area unless there
is a palatal defect. This design maximizes patient comfort.
Attachments: Score-PD, Biloc, PT-Snap, McCollum, etc.
Omega-M interproximal.
