IMPRESSIONING

The following pages describe the impression techniques and laboratory procedures with the Myriad-Connect™ implant.

The impressioning components for the closed tray impression with Myriad-Connect™ include the single use plastic transfer snap on cap which is included in the all – in – one packaging. Also available separately is a titanium closed tray impression post.  The Laboratory analog is included in the implant package.

The Myriad-Connect™ open tray impression post with the long screw can be used for the pick-up impression technique.

Closed – tray transfer cap

.

.

.

The gingivaformer is removed and the yellow plastic single use snap on transfer cap is pressed/snap fitted onto the prosthetic platform face. Impression material is syringed around the cap that is locked into and picked up in the impression

.

.

The laboratory analog is repositioned into the transfer cap within the model following which standard model making procedures are followed.

Closed tray – impression post

.

.

.

The impression post is simply screwed into the implant after removing the gingivaformer.  Impression material is syringed around the impression post and the tray seated in place and removed after the impression is set.

.

.

The impression post is removed and the gingivaformer re-seated.

The impression post is now secured into the laboratory analog and repositioned into the impression.  A tactile snap is felt when the post engages the circumferential undercut groove it created within the impression.

Open tray  pick-up  technique

.

.

The  open tray impression post with the long screw is fastened into the implant.  Impression material is syringed around the impression post and the tray with an open window seated over the impression post to expose the screw extended beyond the tray.  Once the material has set, the screw is opened and the tray removed with the impression post locked into the impression.

.

.

.

The laboratory analog is placed onto the impression post within the impression and the screw fastened through the tray opening to secure the entire assembly.  Model making procedures are carried out as per standard protocols.

LAB PROCEDURES - Myriad-Connect™ Ball

The following pages describe the laboratory procedures for Myriad-Connect™ bar, ball and locator supported overdentures as well as hybrid screw retained prostheses.

Overdenture fabrication with Ball attachments.

Ball attachments screwed into the laboratory analogs.

Gold matrices placed on the ball attachments.

Silicone spacers in place around the gold matrices and  blocking out of the undercuts with wax. Flasking of the denture is now proceeded with over this blocked out situation where the denture acrylic engages only the undercuts on the gold matrices and get locked into the denture base during acrylisation.

Finished overdenture with the matrices in place.

LAB PROCEDURES - Myriad-Connect™ Bar

Overdenture fabrication with a bar and clip attachment.

Gold bar abutments  on the laboratory analogs.

The prefabricated bar is cut to the individual length.

The bar is fixed to the bar abutments  using Pattern Resin (GC) or Duralay.

The bar ready for investing .

The invested bar on the soldering model.

The soldered bar in place.

The matrix / clip  is marked for cutting to the individual length.

The finished bar with matrix in place.

Before flasking and pressing the denture the undercuts are blocked using wax.

Finished overdenture.

The bar clip in place in the denture.

LAB PROCEDURES - Myriad-Connect™ Locator

Overdenture fabrication using Locator attachments.

Locator abutments in place on the laboratory analogs.

Locator matrices on the  abutments  using the silicone spacers  for blocking out the undercuts prior to  acrylisation.

The locator matrices in place in the denture.
