The new additive era of orthodontics: 3D-printed aligners and shape memory polymers—the latest trend—and their environmental implications

Journal of Orthodontic Science
The era of printed aligners has just began in the orthodontic field. Orthodontists have become more interested in 3D-printed in-office aligners. Treatment due to this technology can become faster and more efficient.

Microbial Adhesion and Biofilm Formation on Clear Aligners: A Literature Review [PDF]

Journal of Clinical and Diagnostic Research
Oral cavity is a host for a variety of microorganisms, these microbes tend to adhere to retentive areas in the oral cavity such as deep occlusal grooves on posterior teeth, interdental areas and form biofilm.

Aligners: The Science of Clear Orthodontics

International Journal of Dental and Medical Specialty, 2020
Since their inception, clear aligners have undergone multitude of advancements that aimed to make the orthodontic treatment less conspicuous. Used for moving teeth for alignment and creating healthy and beautiful smiles, like many other orthodontic appliances, clear aligners have proven to be a much more comfortable and esthetic alternative.

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Damage source localisation in complex geometries using acoustic emission and acousto-ultrasonic techniques: an experimental study on clear aligners

Scientific Reports
Passive non-destructive evaluation tools such as acoustic emission (AE) testing and acousto-ultrasonics (AU) approach present a complex problem in damage localisation in complex and nonhomogeneous geometries. A novel AU-guided AE frequency interpretation

Orthodontic treatment of class three malocclusion using clear aligners: A case report

Journal of Oral Biology and Craniofacial Research, 2019
Class III malocclusion is a growth-related challenging condition for orthodontists. We present a case of a 11-year-old girl with a skeletal class III malocclusion with bilateral cross bite, and a functional shift of the lower dental midline. A multiphase

Clear Aligner Attachments: A Comprehensive Review

Turkish Journal of Orthodontics
Clear aligner therapy has gained significant popularity in orthodontics due to its aesthetic advantages and patient comfort. However, achieving complex and precise tooth movements with aligners often necessitates the use of auxiliary features such as attachments.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

FEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...
