Straightforward tip for identifying the type of screwdriver needed for screw-retained implant-supported prostheses
Screw loosening is a common complication of screw-retained implant prostheses.1,2 If the prosthesis was made in another clinic, it is sometimes challenging for clinicians to know what type of screwdriver to use. Using magnification loops with light to visualize the screw's head, making a radiograph to identify the implant type, or trying various available screwdrivers may help select the needed screwdriver. However, in some situations, such as when nonoriginal screws have been used or there are very deep screw channels, identifying which screwdriver should be used is not possible.Straightforward procedure for fabricating a digital cast from a conventional impression with a dental scanner and a free software program
An intraoral scanner allows the recording of hard and soft tissues in a rapid and comfortable way for patients with teeth and attached gingiva.1 In edentulous patients with minimal keratinized gingiva and mobile lingual and buccal tissues, scanning can be problematic, leading to poor quality scans.2 In these situations, conventional impression making and subsequent scanning of the resulting cast may be useful for providing the advantages of the digital workflow, including instant delivery to the dental laboratory and the possibility of working cast-free.A straightforward technique for avoiding the need for a prototype when fabricating monolithic prostheses
Intraoral scanners allow the digital scan to be sent immediately to the dental laboratory to manufacture cast-free monolithic prostheses.1 Making a prototype to minimize the risk of damaging the prosthesis during occlusal adjustment is advised when fabricating monolithic prostheses.2,3 This article shows a straightforward technique for avoiding the need for a prototype evaluation appointment by scanning the occlusion designed by the clinician for the interim prosthesis on the same day as tooth preparation.
