Difficulties in Taking an Impression with an Intraoral Scanner and Making Constructions by Digital Method

Gabriela Kirova

Abstract: Introduction: There are three necessary units of a working digital protocol - an intraoral scanner, a software where the data is processed and the design of the future structure is created and a manufacturing unit. All of the prosthetic structures on implants, require an exact fit of the fixed prosthetic structure to the abutment, whether cemented or screw - retained. When doing the scanning method, it is necessary to transfer the exact position of the implant and to process this information by the software. Aim: The purpose of this article is to examine the main difficulties of taking an impression using an intraoral scanner, as well as those that had arisen after the fabrication of constructions by digital method. Materials and methods: A survey among dentists was conducted, concerning their preferences for taking impressions of implants in the city of Varna. The survey was available on the website of BZS Varna. It was provided electronically via Google Forms. For the time period of April to May 2023, 61 dentists gave their professional opinion. The obtained results were processed with SPSS v.20.0 for Windows. Results: The majority of the respondents are general practitioners in dentistry (68.5%), 26.3% are specialized in prosthetic dentistry and the rest (5.2%) are with qualifications in oral surgery and operative dentistry and endodontics. The results of the study show that some doctors often have difficulties with the scanning method, but most of them do not know which particular area is problematic. The same issue refers to the accuracy and adjustment time of the restorations. This leads to the conclusion that the introduction of digitization in the working process is still complex for clinicians and requires long training time by dental doctors and dental laboratories. Conclusion: Without a doubt, digital impressions have many advantages for dentistry compared to conventional methods. However, difficulties related to the peculiarities of the prosthetic field, as well as clinical and laboratory ones, are noticed.
