Effect of straight and angled abutments on the strain on a zirconia crown and implant in the mandibular second molar region: a FEA-based study

Materiali in tehnologije, 2020
In a literature search no study evaluating implant-supported posterior restorations using zircon crowns with straight and angled abutments was found. In this study, the stress distribution of a zircon-crown restoration that will be prepared by using an angular and straight abutment in a mandibular second-molar deficiency, under functional forces ...

Two cases of calcifying epithelioma beneath the skin of the mandibular angle region.

Japanese Journal of Oral & Maxillofacial Surgery, 1994
In this paper, two cases of calcifying epithelioma arising in the mandibular angle are presented. Case 1 is a 10-year-old boy who had a painless tumor in the right mandibular angle region. Orthopantomograms revealed a radiopaque area in the region. Case 2 is a 49-year-old woman who had a painless tumor in the same region.

Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite

Advanced Functional Materials, EarlyView.
The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.

Dental Microwear Texture Analysis on Radular Teeth

Advanced Materials Interfaces, EarlyView.
3D microwear textures reveal how gastropod radular teeth respond to controlled abrasive contact. Distinct surface signatures distinguish regular abrasion from fracture‐dominated material removal, showing how mineralized coatings, fibrous cores, and substrate properties jointly shape wear and failure in a biological scraping interface.
