Abstract Neochelys is an exclusively European Eocene podocnemidid genus belonging to a linage that reached this continent at the early Eocene. The so far available anatomical information about it is relatively abundant, especially considering that of its shell, at least partially preserved for the eight valid species currently considered.

Changes through growth (ontogenetic) in the braincase of the eutyrannosaurian tyrannosauroid Gorgosaurus libratus are discussed. Most notably, brain cavity endocasts of immature Gorgosaurus are found to more clearly show details of the brain morphology than more mature individuals, a finding that has implications for improving dinosaur paleoneurology ...

Mandibular Fracture in Conjunction with Bicortical Penetration, Using Wide-Diameter Endosseous Dental Implants [PDF]
Prosthodontic rehabilitation of a patient with an atrophic edentulous mandible presents a significant challenge in restoring esthetics and function. The purpose of this clinical report is to describe fracture of an atrophic edentulous mandible opposing ...

A Review of Titanium Zirconium (TiZr) Alloys for Use in Endosseous Dental Implants
Dental implants made from binary titanium-zirconium (TiZr) alloys have shown promise as a high strength, yet biocompatible alternative to pure titanium, particularly for applications requiring small diameter implants.

Five‐Year Results of One‐Piece Zirconia Oral Implants Supporting Three‐Unit Fixed Dental Prostheses
ABSTRACT Objectives The purpose of the present prospective case series was to investigate the clinical and radiological outcome of one‐piece zirconia implants fabricated from 3Y‐TZP with a moderately roughened endosseous surface (Sa = 1.24 μm) to support three‐unit fixed dental prostheses (FDP) after five years in function. Materials and Methods Twenty‐

Soft Tissue Grafting to Improve Implant Esthetics [PDF]
Dental implants are becoming the treatment of choice to replace missing teeth, especially if the adjacent teeth are free of restorations. When minimal bone width is present, implant placement becomes a challenge and often resulting in recession and ...

The effect of platelet-rich fibrin on the acceleration of osteoblast proliferation after endosseous dental implant insertion [PDF]
The osseointegration process of dental implants begins with osteoblast differentiation and proliferation, which is an important aspect of the bone regeneration process.

ABSTRACT Restoring the anterior mandible may be challenging due to both insufficient height and width of the edentulous alveolar ridge; thus, this case report aimed to treat anterior mandibular atrophy by using the inlay technique without the use of mini‐screws or mini‐plates to stabilize the augmented bone fragments. A 19‐year‐old patient who lost his

Surface modifications of dental implants: An overview [PDF]
Osseointegration is the key for long term success of endosseous dental implants. Implant surface properties like surface roughness, surface topography, surface energy and surface composition are the major characters that influence the process of ...
