INTRODUCTION

IN MANY DENTAL PROCESSES, COPIES OF THE HARD AND SOFT TISSUES OF THE ORAL CAVITY AND SURROUNDING AREAS ARE REQUIRED. THE MATERIALS WITH WHICH REPLICAS ARE OBTAINED, FROM A MISSING PART OF A TOOTH TO ALL THE TEETH OF THE UPPER OR LOWER PART (DENTAL ARCHES) OR TEETHLESS PROCESSES ARE KNOWN AS "IMPRESSION MATERIALS". FROM THESE, A POSITIVE OR DUPLICATE IDENTICAL TO THE IMPRESSED BODY IS OBTAINED, FILLING THE IMPRINT LEFT BY THE TISSUES OF THE MOUTH WITH A MATERIAL IN A PLASTIC STATE WHICH LATER HARDENS (DENTAL PLASTER).
