This review aims to provide the dental fraternity with information on the mechanism of botulinum neurotoxin and its therapeutic applications currently prevailing in clinical practice. It is essential, especially for prosthodontic experts treating temporomandibular disorders, bruxism, chronic tooth pain, myofascial pain, etc., to know the pros and cons of botulinum neurotoxin.
The fabrication of removable partial dentures (RPDs) through fully digital procedures remains a challenge. In this study, the authors developed a novel CAD/CAM method for manufacturing a patient-specific RPD in a single piece, using a custom plate. This method, which does not use a gypsum model to combine RPD components, metal framework, denture base, and artificial denture teeth, offers an advantage in the efficiency and accuracy of RPD fabrication over conventional methods. The development of this fully digital RPDs fabrication approach presented in this report will significantly impact prosthodontic clinics worldwide, especially in the context of an increasing aging population.
Interocclusal registration is an important procedure in the digital workflow. This article compares the accuracy of optical interocclusal registration using Trios 3 with different instructions, such as “bite normally,” “bite lightly,” and “bite strongly.” The authors concluded that the use of optical impression methods under a “strong bite force” condition may reduce deviation and allow for stable interocclusal registration. This method will help to obtain accurate prosthodontic treatment in digital dentistry.
Using a dental air turbine and a mannequin, the authors recreated the droplets and aerosols that occur during dental procedures. The key is the high-sensitivity camera and high-intensity LED light source, which allowed for high-quality images of the droplet spreading during the simulated procedure. Using these techniques, the authors demonstrated efficient reduction of droplet and aerosol spread by using oral suction devices. Understanding the spread and diffusion of such particles in the air is a key step in successfully protecting individuals from potentially harmful diseases that can be spread through airborne droplets.
There is a debate among clinicians regarding severe endodontically treated teeth (ETT) in terms of residual tooth substance—whether to extract the tooth or perform partial ferrule. This work conducts the first meta-analysis study that introduces clear evidence-based guidance for clinicians regarding partial ferrule so that they can take appropriate clinical decisions and adequately plan restorative dental treatments of ETT.
