An Improved Direct Injection Technique With Flowable Composites. A Digital Workflow Case Report.

This article presents a clinical technique based on a case report for restoring the contours and shape of the upper teeth involved in the smile display of a young patient. After planning the treatment for the patient using digital tools (Digital pictures, Digital Smile Design, digital waxup, three-dimensional [3D] printed models, mockup), the upper teeth were restored using an improved injection technique. This improved technique involves the direct injection of flowable composite resin using clear polyvinyl siloxane molds made from 3D-printed models of the patient.

Layperson's preference of the transverse occlusal plane in asymmetric facial model.

Objective: Facial asymmetries are common, especially deviated nose and chin. The clinician must consider these variables when establishing the smile, placement and angulation of the occlusal plane. The purpose of this article is to determine if nose and chin deviations affect the perception of laypeople towards different angulations of the occlusal plane cant.

Comparison of a non-destructive technique using three-dimensional imaging and histoanatomical chemical dissolution for dental morphology analysis.

Aim: The present work aims to compare a digital dental histoanatomical analysis method with chemical enamel dissolution for the study of dental morphology.

Material And Methods: Extracted maxillary anterior teeth were scanned under microcomputed tomography (μCT) (μCT 40; Scanco Medical), segmented, and reconstructed three-dimensionally (Amira, version 5.5.

[Differential diagnosis of syncope attack in the district hospital].

With the aim to establish a rational and effective programme for the diagnosis of syncopes for district hospitals 159 patients with previous syncopes underwent an examination programme which contained the whole specialized diagnostic spectrum of a district hospital up to the higher-frequent right-atrial stimulation. In 141 patients (88.7%) the diagnostics was successful, 18 cases (11.

[Morphometric studies of the aging of human submaxillary glands (author's transl)].

Morphometric examinations were made on hematoxylin-stained paraffin sections of 43 human submaxillary glands, in order to determine and describe histological changes of this organ during the aging thereof. The number of fat cells per unit area increases in the first decades, whereas that of the striated ducts decreases. Obviously, striated ducts differentiate earlier than serous acini, with the former thus being less subject to involution with aging than the latter.
