Evaluation of the Clinical Accuracy of Implant Abutment-Level Impression Technique Using Digital Superimposition of Customized Abutment
INTERNATIONAL JOURNAL OF PROSTHODONTICS(2021)
Abstract
Taking a conventional implant abutment-level impression with the gingival retraction technique can cause side effects such as gingival recession and bleeding. In order to overcome these problems, an impression technique using digital superimposition of the customized abutment has been newly introduced. In this technique, digital impression data and prescanned abutment data are superimposed to reproduce the abutment's location and shape on computer-aided design software. The present investigation was conducted to evaluate the clinical accuracy of the newly adapted digital superimposition impression technique by assessing the fit of fabricated prostheses. The results showed clinical efficacy of this technique, showing clinically acceptable marginal and internal fit and convenience.
