Cervico Mold

The Cervico Mold is an in-office tool used for the fabrication of the cervico healing abutments and impression posts.

Overview

The Cervico Mold is an in-office tool used for the fabrication of the cervico healing abutments and impression posts.

It can also be used for the duplication of a modified healing abutment or temporary prosthesis to a duplicate impression post. It features 17 wells that can be used for all of the above purposes.


What’s included:
  • Mold Base
  • Centered Silicone Insert
  • Base screw driver
  • VPI prosthetic connection inserts

    A variety of VPI prosthetic connection inserts is available, in order to facilitate multiple implant systems from multiple companies and their respective connection types and sizes.

How Cervico Mold works

How it works

The top ring of the Cervico Mold carries a letter coding that corresponds to the shape and size of the well of the silicone insert.

The bottom ring of the base has 36 sockets which accept the VPI Prosthetic connection inserts (VPI inserts). These sockets are divided in four groups that allow the installation of the VPI inserts in four different depths, ranging from 0mm (crestal implant placement) to -3mm (sub-crestal implant placement of -1mm, -2mm and -3mm). All the sockets of the same group have no difference to each other. The reason for providing many sockets of the same height is to allow the potential installation within the Cervico Mold of many different VPI inserts. This will allow the same mold to be functional with many different implant systems, as implants range in connection type and size.

The top ring of the Cervico Mold, along with the silicone insert installed in a stable position within it, can rotate in relation to the bottom ring of the Cervico Mold. This allows the alignment of different wells of the silicone insert with different VPI inserts installed into the bottom ring of the Cervico Mold.

What is a VPI prosthetic connection insert?

A VPI Prosthetic connection insert is a unit with innovative design that replicates the prosthetic connection and platform of a given implant. The innovative external design allows the installation of the VPI insert into the bottom ring of the Cervico Mold in only one functional orientation and a stable position while its internal design allows it in many occasions to be functional with multiple platform sizes of the same prosthetic connection. Each VPI insert is available with a retention screw that allows its safe coupling to the bottom ring of the Cervico Mold. A plethora of different VPI inserts are available in order to fulfil the clinical needs. 

Fabrication process

Cervico healing abutment

Step 1

Cervico Mold Step 1

Couple thread the temporary abutment into the desired well, manually.

Step 2

Cervico Mold Step 2

The printed dot on the silicone insert is correlated to the orientation of the prosthetic connection of the VPI Prosthetic connection insert and thus to the one of the temporary abutment and implant.

Step 3

Cervico Mold Step 3

Fill in the open space with suitable dental composite material and light cure for 40 sec.

Step 4

Cervico Mold Step 4

In case of large size wells the space can be filled and light cured in two increments in order to ensure proper curing of the composite material.

Step 5

Cervico Mold Step 5

Unthread and remove the cervico healing abutment from the mold and light cure for additional 20 sec. Clean the well of the mold with a cotton tip soaked in alcohol.

Step 6

Cervico Mold Step 6

Secure the cervico healing abutment on the easy grip handle and proceed with polishing of the composite surface, using a micromotor. Utilize the polishing mop and polishing paste to smoothen the composite surface, at 10000 rpm.

Duplication Process

The Cervico Mold can be utilized for the duplication of the sub-gingival portion of a modified healing abutment or a temporary prosthesis to a duplicate impression post.

If modification of the sub-gingival portion of the cervico healing abutment has been initiated, the duplication process must be used.

Step 2

Duplication process step 1

Coat the duplication well with vaseline and couple thread the modified healing abutment or temporary prosthesis.

Step 3

Duplication process step 2

Fill the open space with clear silicone impression material.

Step 4

Duplication process step 3

Let the silicone set for approximately 3-6 minutes according to manufacturer guidelines.

Step 5

Duplication process step 4

Remove the modified healing abutment, or temporary prosthesis from the mold.

Step 6

Duplication process step 5

Couple thread the core impression post.

Step 7

Duplication process step 6

Fill the open space available with the suitable dental composite material.

Step 8

Duplication process step 7

Light cure the composite material for 40 sec. Then, remove the customized impression post from the mold and light cure for additional 20 sec.


Modified Impression Post

Modified Impression Post

The generated custom impression post is an exact duplicate of the modified healing abutment, or temporary prosthesis at least at its sub-gingival portion.

A VPI Prosthetic connection insert is a unit with innovative design that replicates the prosthetic connection and platform of a given implant. The external design allows the installation of the insert into the base of the mold in only one functional orientation and a stable position. The internal design of the VPI Insert allows it in many occasions to be functional with multiple platform sizes of the same prosthetic connection. Each insert is available with a retention screw that allows its safe coupling to the mold. The insert has its item number and an arrow laser printed on its outer surface. A plethora of different VPI Inserts are available in order to fulfil the clinical needs. Please refer to the VPI Prosthetic connection inserts compatibility chart in order to determine the one that fits your needs.


Insert installation process

Installation process

Identify the desired open socket of the mold and install the VPI insert by light pressure. The insert will be able to be installed if only you align the arrow of the insert to the triangular orientation mark of the base. Couple thread the insert to the underside of the mold utilizing the provided VPI Cervico 2mm Allen Screw driver and retention screw.
