Double site-bond percolation model for biomaterial implants [PDF]

, 2011
We present a double site-bond percolation model to account, on the one hand, for the vascularization and/or resorption of biomaterial implant in bones and, on the other hand, for its mechanical continuity. The transformation of the implant into osseous material, and the dynamical formation/destruction of this osseous material is accounted for by ...

Imaginologic resources used in diagnosis of root resorptions: comparative study

RGO: Revista Gaúcha de Odontologia, 2022
Objective: Compare the accuracy of early diagnosis of simulated internal root resorptions and external root resorption, using digital periapical radiography and cone beam computed tomography.

Robust acute myeloid leukemia engraftment in humanized scaffolds using injectable biomaterials and intravenous xenotransplantation

Molecular Oncology, EarlyView.
Patient‐derived xenografts (PDXs) can be improved by implantation of a humanized niche. We tested different biomaterials and approaches, and demonstrate that the combination of an injectable biomaterial for scaffold creation plus an intravenous route for acute myeloid leukemia (AML) xenotransplantation provide the most convenient and robust approach to

Dimensional evaluation of root resorption areas in differing severity of chronic periodontitis: A scanning electron microscopic study

Contemporary Clinical Dentistry, 2017
Aim: The aim of this study was to evaluate root surface alterations in terms of location, length, and depth of root resorption in the gingival, middle, and apical third of the mesial and distal surfaces of the root in healthy and periodontally affected ...

High Repetition Rate Laser‐Induced Printing of Bioink with Picosecond Pulse Durations: Optimization of the Printing Process

Advanced Engineering Materials, EarlyView.
This study explores the use of laser‐induced forward transfer in the picosecond regime to create in vitro biomodels. Focusing on hydrodynamics and rheology, it investigates jet dynamics through time‐resolved imaging, optimizing laser fluence, biological ink viscosity, and printing distance to precisely control the volume and location of bioink ...

Apical Root Resorption after Orthodontic Treatment

Česká Stomatologie a Praktické Zubní Lékařství, 2012
Aim: The aim of the present study was to assess the incidence of apical root resorption in patients treated with fixed orthodontic appliances and find out whether the frequency of their occurrence depends on sex, patient's age, Angle class malocclusion ...

A continuum treatment of growth in biological tissue: The coupling of mass transport and mechanics [PDF]

, 2003
Growth (and resorption) of biological tissue is formulated in the continuum setting. The treatment is macroscopic, rather than cellular or sub-cellular. Certain assumptions that are central to classical continuum mechanics are revisited, the theory is reformulated, and consequences for balance laws and constitutive relations are deduced.

Modelling the anabolic response of bone using a cell population model [PDF]

J Theor Biol 307 (2012) 42-52, 2011
To maintain bone mass during bone remodelling, coupling is required between bone resorption and bone formation. This coordination is achieved by a network of autocrine and paracrine signalling molecules between cells of the osteoclast lineage and cells of the osteoblastic lineage.

Bioresorbable and Wireless Rechargeable Implanted Na‐ion Battery for Temporary Medical Devices

Advanced Functional Materials, EarlyView.
An all‐solid‐state bioresorbable Na‐ion battery is developed, composed entirely of bio‐eliminable materials. In vivo and ex vivo tests confirmed harmless disintegration of this implanted battery. Lifetime of the implanted battery can be precisely controlled by adjusting the dissolvable encapsulation layer's thickness.
