Biopolymer-based membranes associated with osteogenic growth peptide for guided bone regeneration
(2018-03-14)
Barrier membranes for guided bone regeneration (GBR) mainly promote mechanical maintenance of bone defect space and induce osteopromotion. Additionally, biopolymer-based membranes may provide greater bioactivity and ...
Different oxides used as diffusion barriers in composite hydrogen permeable membranes
(Elsevier Science, 2006-04)
Composite Pd-Ag membranes supported on modified porous stainless steel substrates were prepared by sequential electroless plating. To improve the stability of the Pd-Ag alloy, two different intermediate layers of α-Fe2O3 ...
EFFECT OF HYDRATION UPON THE FLUIDITY OF INTERCELLULAR MEMBRANES OF STRATUM-CORNEUM - AN EPR STUDY
(Elsevier Science BvAmsterdamHolanda, 1995)
Guided tissue regeneration with a bioabsorbable polylactic acid membrane in gingival recessions. A histometric study in dogs
(Amer Acad PeriodontologyChicagoEUA, 2000)
Experimental validation of computational models for mass transport through micro heterogeneous membranes
(Elsevier Science, 2013-02-27)
This work describes a setup for the experimental and theoretical study of the mass transport of a penetrant through a two-dimensional model-material microstructure consisting in a homogeneous matrix with slender obstacles. ...
Calcium sulfate and PTFE nonporous barrier for regeneration of experimental bone defects
(Medicina Oral S L, 2008-06-01)
The aim of the study was to evaluate the possibility to obtain guided bone regeneration with two types of physical barriers (calcium sulfate and PTFE nonporous barrier) in surgical defects created in rat parietal bones. ...
NaA zeolite as an effective diffusion barrier in composite Pd/PSS membranes
(Elsevier Science, 2009-04)
Palladium composite membranes on porous stainless steel were prepared by electroless plating. In order to obtain a thin palladium film, an intermediate layer was necessary to modify the pore size of the substrate and form ...
Flunitrazepam-membrane non-specific binding and unbinding: Two pathways with different energy barriers
(Elsevier Science, 2002-02-19)
The effect of molecular packing on flunitrazepam's ability to interact with bio-membranes was studied using dipalmitoylphosphatidylcholine monomolecular layers at the air-water interface as a model membrane. Flunitrazepam ...
Short-term use of an exposed polypropylene barrier in the preservation of alveolar bone after extraction: randomized clinical trial
(2021-01-01)
This study was performed to evaluate the short-term preservation of alveolar bone volume with or without a polypropylene barrier and exposure of the area after extractions. Thirty posterior tooth extraction sockets were ...
Absorbable versus nonabsorbable membranes and bone grafts in the treatment of ligature-induced peri-implantitis defects in dogs: A histometric investigation
