Summary

Removable partial dentures (RPDs) are traditionally fabricated by lost-wax casting technique, a time-consuming and very laborious manual technique. Recently, fabricating removable partial dentures using computer designing and laser sintering techniques have been introduced. The purpose of this study was to evaluate the patient satisfaction with new computer-generated removable partial dentures and compare it to the traditional removable partial dentures.

Conditions

  • Partially Edentulous Jaws

Interventions

DEVICE

Laser-sintered removable partial denture

The master cast was scanned using 3D scanner. In the digital file, the path of insertion was determined using a special software. The survey line was drawn and all undesirable undercuts were eliminated. After that, the entire framework design was built virtually 3 dimensionally using a special software (3Shape Software) according to the specified design in three steps: deciding the contour of the component, building the tissue surface then creating the polished surface. The file was saved in STL file and was transferred to rapid prototyping machine. Framework was produced by selective laser sintering technique using the alloy powder (Sintech Metal).
