IMPRESSIONS AND MODELS

Transfer-type and pick-up type impression coping

The devices used to make the impression have been specially developed to transfer the clinical situation to the working model in an exact fashion. They are available in different diameters and replicate the emerging profiles of the gum conditioners used in the IMPLOGIC® and IMPLASSIC implant systems.

Pick-up type impression copings for use with standard/closed impression trays are available for the IMPLOGIC® and IMPLASSICimplant systems. Transfer-type impression copings for use with individual open impression trays are available for the IMPLOGIC®/IMPLASSIC,IMPLASSIC TR2 and TRW2 implant systems.

Designed to achieve optimum results, they must used in combination with suitable materials and equipment, meaning impression materials which allow stable seating and which, in the case of the pick-up technique, faithfully reproduce the shape. The impression trays must be rigid and stable, for both the standard technique or the transfer technique.

The devices must be assembled and fixed to the implants using the dedicated lag-screw. The screw may be tightened manually or using the appropriate screwdriver.

Laboratory analogues

Available in various diameters, they faithfully replicate the internal portion of the IMPLOGIC® and IMPLASSICsystems to be implanted, the internal portion and the collar of the IMPLASSIC TR2 and TRW2 implant systems. Assembled on the transfer impression, they are used by the dental technician to develop the working model.

The external portion is realised so that it remains firmly anchored to the material used to develop the model. There is a rounded channel in the cervical portion of the analogue which is useful for the stable positioning of the false gum created with soft, pliable materials (resin or silicon).

As with transfers, the analogues can be reused, however it is advisable to inspect their integrity before making the impression and developing the model. Given that these devices, together with the prosthetic procedures, must guarantee the precision of the prosthesis and its correct insertion in the oral cavity.

Pillar counterparts

These faithfully reproduce the heights and angulations of the straight and pre-angled pillars used in the IMPLOGIC® and IMPLASSIC implant systems. They are colour coded according to diameter and grooving to identify the differences in angulations.

Pillar counterparts are useful tools, both during surgery and in the prosthetic stage. In fact, the surgeon uses them to check the correct position of the implant in relation to the prosthetic axis, while the technician uses them to choose suitable pillars after having developed the working model. This saves time and avoids the need for investing in large stocks of prosthetic devices.

Transfers and analogues for the direct technique using a full pillar

Available for the IMPLASSIC TR2 and TRW2 implant systems, these devices have been designed to precisely translate the clinical situation to the working model when using a full screwed pillar.

A plastic cap is available, which reveals the implant collar and remains imprisoned in the material used for the impression. The laboratory analogues which are then added to the impression will differ depending on whether the solid abutment screwed to the implant was milled by the clinic or left fully intact.
