Biomechanical behavior of customized scaffolds: A three-dimensional finite element analysis
(Elsevier, 2022-09)
Teeth loss due to periodontal diseases, trauma, or infections often causes dimensional loss in the affected maxillary. In patients with reduced maxillary size, restoration of chewing function and esthetics with endosseous ...

Deposition of bioactive gelatin coatings on porous titanium: Influence of processing parameters, size and pore morphology
(Elsevier, 2021-09)
In this work porous commercially pure Ti substrates fabricated by spacer-holder technique (50 vol% NH4HCO3 and three range pores sizes, 100–200 μm, 250–355 μm and 355–500 μm) were coated with two types of gelatinous ...

Surface Modification of Porous Titanium Discs Using Femtosecond Laser Structuring
(MDPI, 2020-06)
The failure of titanium implants is associated with two main problems that include the bone resorption and fracture of the surrounding bone tissue (stiffness incompatibility) and implant loosening (poor osseointegration). ...
