Every human smile is unique and special, reflecting the different shapes, textures, and colors of the teeth as well as their combinations. This uniqueness conveys a direct and specific message when it comes to creating a new smile design. Dentists need to consider the 'unity of the whole' concept in this task, which involves bringing together biology, structure, function, and esthetics to create the fifth dimension of the smile. This approach is quite different from the traditional one. A smile reflects the personality and emotional state of the patient, and the translation of this into a new smile design occurs in various ways. This can be performed either through analog methods or digitally; however, the use of visual language will assist the dentist and dental technician in the creation of a personalized smile design. Nowadays, with the significant digital advances that have occurred in dentistry, there are systems on the market that help the dental team to create a personalized new smile design for each specific patient. The Rebel system is one example of such a system. It is actually a virtual laboratory that creates individualized smile designs in three dimensions. The system, with its very sophisticated artificial intelligence (AI)-based software, immediately creates a digital wax-up (STL file). It is therefore simple to use for dentists and dental technicians at all skill levels because the direct mock-up and wax-up stages are eliminated.

Succinyldiamide derivatives are important structural motifs in various natural products, pharmaceuticals, and functional materials. Herein, a novel, mild, and environmentally friendly method was developed for synthesizing functionalized succinyldiamides each containing a quaternary carbon center. This strategy was designed to involve photocatalytic decarboxylation of readily available oxalic monoamide using a non-precious metal photocatalyst, 4CzIPN, followed by a free-radical addition/Smiles rearrangement cascade reaction of -aryl--(arylsulfonyl)acrylamides.

: Digital diagnostic waxing is a contemporary alternative to the conventional wax-up method. This study aims to evaluate the impact of both techniques on the perceived frontal symmetry in aesthetic treatment planning. Dental symmetry significantly influences smile perception and, consequently, the acceptance of treatment outcomes, highlighting its clinical importance in restorative dentistry.

An important consideration in their experimental design is the choice of initialization procedure as this influences the duration of initial-condition memory, with implications for interpreting the temporal evolution of both the ensemble-mean and ensemble-spread. Here we leverage the strategic design of the 100-member Community Earth System Model version 2 (CESM2) SMILE to investigate the dependence of ensemble spread on the method of initialization (micro- vs.
