Fabrication of additively manufactured custom impression copings based on stock abutments.

This article describes a dental implant impression technique using custom impression copings. The implant impression coping was designed by using a dental computer-aided design software program and manufactured by using additive methods. The impression copings were cemented to stock abutments, and the assemblies were used to make the definitive pick-up impression.

Fabrication of a CAD-CAM custom healing abutment guided by a conventional dental radiograph for delayed loaded dental implants: A dental technique.

This article describes a technique for fabricating a custom anatomic healing abutment for delayed loaded implants by using the computer-aided design and computer-aided manufacturing (CAD-CAM) technology from a polymethyl methacrylate (PMMA) blank. The dimensions of the custom healing abutment are measured from a conventional dental radiograph and diagnostic casts. The healing abutment is used in the second surgical stage to guide soft tissue healing. The resulting soft tissue contour guides the design of the mucosal part of the custom implant abutment.
