Tooth transposition: two case-reports and literature review

open access: yesRevista da Faculdade de Odontologia de Porto Alegre, 2018
Tooth transposition is a rare developmental disorder in which a normal tooth erupts in an inappropriate position. The change in position occurs between two adjacent teeth within the same quadrant.

Maxillary canine anomalies and tooth agenesis [PDF]

open access: yesEuropean Journal of Orthodontics, 2005
The aims of the study were to analyse the records of 26 subjects (18 females, eight males) with maxillary canine-first premolar transposition (Mx.C.P1) together with 160 subjects with a palatally displaced canine (PDC) to determine the pattern of tooth agenesis in these cases and to compare them with similar samples reported in the literature.

Orthodontic treatment of a complete transposed impacted maxillary canine

open access: yesJournal of Dental Sciences, 2015
Tooth transposition is a positional interchange of two adjacent teeth. Transposition most often occurs at maxillary canine. Moving transposed teeth to their normal positions is challenging because this requires bodily movement and translation of one ...

Localization of Impacted Maxillary Canines and Root Resorption of Neighboring Incisors using Cone Beam Computed Tomography in People Aged 12-20 in Sari [PDF]

open access: yesJournal of Mazandaran University of Medical Sciences, 2023
Background and purpose: This study aimed to localize impacted maxillary canines and root resorption of neighboring incisors using cone beam computed tomography (CBCT) in 12-20-year-old patients referred to two private oral and maxillofacial radiology ...

Comparative and functional anatomy of masticatory muscles and bite force in opossums (Didelphimorphia, Didelphidae)

open access: yesThe Anatomical Record, EarlyView.
We describe the functional anatomy of masticatory muscles in nine opossums, finding a generalized anatomical pattern with differences related to skull morphology. Variation in quantitative myological data and estimated bite force was mostly related to size, and the increase in bite force supports dietary diversification associated with size increase ...

A Novel Technique to Expose Impacted Canine by Using Punch Biopsy Instrument

open access: yesJournal of Indian Orthodontic Society, 2019
In orthodontics, the impaction of maxillary canine is a common problem. Treatment for this clinical hitch usually requires surgical exposure of the impacted tooth, followed by orthodontic traction to align the tooth in the arch.

The predictability of orthodontic tooth movements through clear aligner among first-premolar extraction patients: a multivariate analysis

open access: yesProgress in Orthodontics, 2022
Background The purpose was to determine the predictability of tooth movements through clear aligner among premolar extraction patients and to explore the effects of various factors on tooth movements.

The relationship between form and function of the carnivore mandible

open access: yesThe Anatomical Record, EarlyView.
Abstract Dietary morphology diversified extensively in Carnivoraformes (living Carnivora and their stem relatives) during the Cenozoic (the last 66 million years) as they evolved to capture, handle, and process new animal and plant diets. We used 3D geometric morphometrics, mechanical advantage, and finite element analysis to test the evolutionary ...

Does salinity make a difference—Kidney anatomy of Saimaa (Pusa saimensis) and Baltic ringed seals (Pusa hispida botnica)

open access: yesThe Anatomical Record, EarlyView.
Abstract As habitat salinity markedly differs between the endangered, freshwater‐dwelling Saimaa ringed seal (Pusa saimensis Nordquist, 1899) and the brackish water‐inhabiting Baltic ringed seal (Pusa hispida botnica Gmelin, 1788), we investigated whether this difference has resulted in morphological changes to their kidneys.

The Mechanics of Maxillary Molar Distal Movement Using Class II Carriere Motion Appliance: A Finite Element Study

open access: yesApplied Sciences
To clarify the mechanics of tooth movement produced by a unique distalizer, Class II Carriere Motion appliance (CMA), in which the maxillary canine is connected to the maxillary first molar with a stiff bar, long-term tooth movement was simulated by the ...
