This study is being conducted at Ege University Faculty of Dentistry to evaluate the accuracy of different dental scanning technologies in people who need full dentures for their upper or lower jaws. The research focuses on comparing three types of scanning technologies to see which one provides the most precise digital representation of a patient's mouth. This is important because accurate scans can help create better-fitting dentures, improving comfort and functionality for individuals who have lost all their teeth in one or both jaws. In this study, dental impressions are first taken from 30 patients using a traditional method with silicone and plaster to create models of their mouths. These models are then scanned with a high-tech industrial scanner to create a reference. Each patient is also scanned three times with three different types of intraoral scanners, which use various advanced technologies to capture the details of the mouth. The data from these scans is analyzed to compare how closely they match the reference models. The study uses sophisticated software to perform statistical analyses, ensuring that the results are accurate and reliable. By doing this, the study aims to determine which scanning technology is the most effective, potentially leading to improvements in denture fitting and patient satisfaction.

Treatment Groups
Study Objectives

4 intervention groups are designated in this study

This study does not include a placebo group 

Treatment Groups

Group I

Active Comparator
The 3Shape E4 laboratory scanner (EOS) is a desktop laboratory scanner with an indirect scanning procedure. It features fast and accurate scanning technology. With 3Shape E4 scanners, the scanning process begins as soon as you place the model inside the scanner. It records the digital measurement data of the model. In our study, the primary model (reference scan) obtained by taking conventional measurements from the patient is scanned using a laboratory scanner, and digital data is obtained.

Group II

Experimental
It is an intraoral scanner that works with active triangulation scanning technology. In our study, the purpose of using the intraoral scanner is to take intraoral digital measurements by scanning edentulous ridges. They record the patient's intraoral images in high resolution.

Group III

Experimental
It is an intraoral scanner that works with multi-unit-capture scanning technology. In this study, using the new generation digital scanning technology of iTero Lumina, intraoral digital measurements are taken by scanning edentulous ridges. They record the patient's intraoral images in high resolution.

Group IV

Experimental
It is an intraoral scanner that works with confocal microscopy scanning technology. The purpose of using the intraoral scanner in our work is to take intraoral digital measurements by scanning edentulous ridges. They record the patient's intraoral images in high resolution.
