Aligner-induced tooth movements in three dimensions using clinical data of two patients [PDF]

open access: yesarXiv
The effectiveness of a series of optically transparent aligners for orthodontic treatments depends on the anchoring of each tooth. In contrast with roots, the crowns' positions and orientations are measurable with intraoral scans, thus avoiding any X-ray dose.

Transformer-Based Tooth Alignment Prediction With Occlusion And Collision Constraints [PDF]

open access: yesarXiv
The planning of digital orthodontic treatment requires providing tooth alignment, which not only consumes a lot of time and labor to determine manually but also relays clinical experiences heavily. In this work, we proposed a lightweight tooth alignment neural network based on Swin-transformer.

Porcelain Surface Roughness, Color and Gloss Changes after Orthodontic Bonding [PDF]

open access: yes, 2006
The purpose of this study was to evaluate the alteration in surface characteristics after orthodontic debonding of two types of porcelain systems commonly used in prosthetic dentistry. For this purpose, porcelain specimens were fabricated from low-fusing

Deformation Quantization of Certain Non-linear Poisson Structures [PDF]

open access: yesarXiv, 1998
As a generalization of the linear Poisson bracket on the dual space of a Lie algebra, we introduce certain non-linear Poisson brackets which are ``cocycle perturbations'' of the linear Poisson bracket. We show that these special Poisson brackets are equivalent to Poisson brackets of central extension type, which resemble the central extensions of an ...

Orthodontic Bracket Adjustable In Different Angles

open access: yesAnnals of Abbasi Shaheed Hospital and Karachi Medical & Dental College
Modern advancements in dentistry, like as laser technology and digital dentistry, are increasing the comfort and effectiveness of dental procedures. Dental lasers, for instance, can now be utilized more precisely and less invasively for treatments like ...

Force to Debond Brackets from High-fusing and Low-fusing Porcelain Systems [PDF]

open access: yes, 2006
The purpose of this study was to test the hypothesis that porcelain surface finishing, ie, low- and high-fusing porcelain, has an effect on the amount of force required to debond orthodontic brackets. A total of 20 high-fusing and 20 low-fusing porcelain
