Abstract
Aim: The implementation of computer applications has become a necessary step in providing higher quality service to patients receiving dental/medical prosthodontic restorations.
Thus, the aim of this research was to determine the time necessary for the vestibuloplasty
fixation plate manufacturing using the computer aided method based on the computer-
aided design and computer-aided manufacturing (CAD/CAM) technologies, and then compare it with the conventional method, which is presently used in common practice. Methods: During this research two vestibuloplasty fixation plates were manufactured. The first one was made as per conventional method using the alginate impression and hard stone, while the other one was made using new computer aided method based on the CAD/CAM technologies. Using both methods, we analysed the total time for fixation plate manufacturing
as well as necessary steps in process. In addition, access, documentation creation and transport between dental laboratory and the dental/medical office time were also analyzed.
Results: The use of the CAD/CAM technologies ensures the continuity of all steps in the process of vestibuloplasty fixation plate production. Electronic documentation created in this way can be stored at a network server and become available for wider range of users. Data analysis indicates that the number of steps used in the computer based method is decreased
for 18,1 % compared with the conventional method. Improvements indicate that documentation preparation time was decreased for 30,0 %, and time for documentation access
was reduced for 86,7 %. Time for documentation creation was decreased for 40,0 %. This computer method also increased transport time efficiency for 83,3 %. In comparison with the conventional method, the total time necessary for fixation plate manufacure was significantly reduced for 51,6 %. Discussion: The use of computer aided method based on the CAD/CAM technologies in comparison with the conventional method significantly accelerates
production time in dental/medical office thus raising the level of service.
