A Modified Plastic Shell Technique for Cement-Retained Implant Restorations
The best possible fit of prosthetic components should be the aim of the clinician. The technical report presented here describes the use of a modified plastic shell technique for modeling a cement-retained single-implant restoration. This approach will help to prevent potential errors caused by the wax modeling technique.Abstract
