Impression Post & Core Restoration Case

Overview

This article explores single and dual impression post & core restoration case examples. We used an AutoScan-DS-EX Pro blue light 3D scanner with exocad software. Since exocad does not feature the post & core design process, we defined the restoration type as a telescope crown. This helped avoid undercut.

Single Post & Core Case Study

1. Single Post & Core impression Scan

Scan the single Post & Core impression with DS-EX 3D scanner and get the scan data.

2. CAD Design

Import the scan data into exocad directly and start designing.

  • 1.Drawing Margin
  • 2.Set Bottom Parameters
  • 3.Set Tooth Position
  • 4.First Layer Telescope
  • 5.Finish Design 

3. Printing

  • 1. Setting
  • 2. Printing
  • 3.Use line cutting to cut the post&core from the metal plate. 
  • 4.Then polish the Post&Core and blast it.

4. Try-in

Dual Post & Core Case Study

1. Impression scan

Scan the impression with DS-EX scanner and get the scan data.

2. Design

Import the scan data into exocad directly and start designing.

  • 1. Drawing Margin
  • 2. Set Bottom Parameter
  • 3. Set Tooth Position
  • 4. First Layer of Telescope 
  • 5.Finish the design 
  • 6.Separate the Post&Cores
    Use Magics software to design the finished data to seperate the post&cores

3. Printing

  • 1. Setting
  • 2. Printing
  • 3. Use line cutting to cut the post&cores from the metal plate
  • 4. Metal finishing

4. Try-in
