Abstract: The term maxilla, as gcrierally used in human anatomy, corresponds to the premaxilla and the maxilla in lower animals, All mammals, with the exception of the bats and certain edentates, possess premaxillary bones which generally remain distinctly separated from the maxilla on the facial aspect (Walter, ’39). Ever since the publication of Vesalius’ De hurnanni corporis fabrica in 1543, there has been controversy over the premaxilla in man. It is generally understood that the classical teaching of the anatomy of Galen before Vesalius was based on the anatomy of monkeys. Vesalius denied the existence of the premaxillary suture on the facial aspect of man as was described by Galen, but he noticed the presence of the palatine portion of the premaxillary suture on the palate. Columbus (1559)’ Fallopius (1561)’ Kollikcr (1882), Fawcett (’11) and others also observed thc palatine portion of the suture. Albinus (1746), Qoethe (1786) and Rosenmueller (1804) described the endofacial portion of the premaxillary suture. Camper (1 778) emphasized the absence of the suture on the facial aspect. Blumenbach (1776), who named the premaxilla as the intermaxillary bone, recognized its human distinction. Wood Jones (’29, ’47) regarded the early facial absence of the premaxilla as a “specific human

Abstract: This invention provides a hearing aid of the kind which has a transmitter element and a receiver-transducer element having a vibrating element The receiver element is suitable for being placed, preferably movably, in the mouth of the user The receiver element includes a device for supporting and holding the vibrating element The device for supporting and holding the vibrating element is formed so that when the vibrating element is in place it is in permanent contact either with at least one tooth or with the palate bone, thereby providing sound transmission to the inner ear by bone conduction

Abstract: Introduction When an orofacial cleft lip is discovered, precise characterization of this malformation is necessary, especially the extension of this cleft to the secondary palate. We aimed to develop and evaluate the feasibility/reproducibility of a score-based quality control for the visualization of the fetal hard palate during the second-trimester scan. Material and methods All ultrasound images of fetal hard palate assessed routinely during second-trimester scan were retrospectively retrieved for a 6-month period. One hundred of these images were randomly selected and analyzed by two blinded reviewers, according to a scoring system (0-6 points). Criteria retained in the score were complete palate bone horizontal plate, presence of two pterygoid processes, visible alveolar ridge, and horizontal axis of insonation. A score ≥4 defined images of good quality. Inter- and intra-reviewer reproducibility was assessed. Results Inter-reviewer reproducibility was excellent with significant correlation (Pearson coefficient 0.953; P 0.8. Rates of images of good quality (score ≥ 4) were 75%-77%, also with excellent agreement (κ coefficient 0.89, 95% CI 0.79-0.99). Intra-reviewer reproducibility retrieved the same results (excellent agreement) except for the axis of insonation (satisfactory agreement). Conclusions This simple image scoring system for the fetal palate is easy, has excellent inter- and intra-reviewer reproducibility and could also help sonographers to correctly identify the palate structure.
TL;DR: In this paper, the authors described a rapid orthodontics treatment method after corticotomy and the skeletal anchorage plate, which comprises the steps of: incising gums within a range established in consideration of a set of teeth to be corrected; incising front and rear surfaces of a cortical bone; suturing incised gums; and placing an orthodentic appliance on the teeth and applying tensioning force to the set of false teeth, thereby to correct irregularities of the teeth.
