Polymers have also played a major part in dental restorations and replacements [ 6 ]. Thus, the macrospheres possess an intrinsic property for bone homeostasis. These components are held together with graded interlocking surfaces either with use of embedded fibers or by subtle melding of not-so dissimilar materials inside junctional zones such as the cementum-dentine junction Figure 10 [ ].

Evolving Marine Biomimetics for Regenerative Dentistry

Nevertheless, it is anticipated that with continuous advances in biochemical engineering and the continuous technical advances in materials modification to fine-tune material properties, a window of new opportunities will be opened for tooth regeneration and repair. Such organisms represent a deep and diverse reserve of materials, substrates and structures that can facilitate tissue reconstruction within lab-based cultures.

Metals and ceramics have been predominant in fixing and replacing the major hard tissues of the tooth. The extracted and concentrated preparation of water-soluble matrix WSM has shown considerable potency. Part I.

Making a tooth: Biomaterial aspects of Interpore porous hydroxyapatite. Over the years, the pursuit of tooth regeneration and total tooth repair has been one of the main goals of research in regenerative and restorative dentistry. Reddy S. Isolation, characterization and biological evaluation of jellyfish collagen for use in biomedical applications. The effectiveness of nacre WSM in bone formation, remodeling potential and osteoporosis treatment; A , B Nacre powder and WSM extract induce osteoblast mineralization via consequential molecular signaling pathways e.

Effect of a test dentifrice containing nano-sized calcium carbonate on remineralization of enamel lesions in vitro. In one case, marine sponges have been farmed with the express purpose of producing bioactive metabolites in practical amounts [ 70 ] Cloning of the gene coding for the metabolite of interest has been advanced as a solution for this that can be sustained for all needs and applications [ 71 , 72 ].

Evolving Marine Biomimetics for Regenerative Dentistry

Coral, a new biomedical material. This property is something we want to exploit. Ideas for re-design of the structure of microshells via genetic and metabolic routes.

However, their usage in regeneration therapies has not been fully exploited in practice because of the bias towards well-established restorative materials such as titanium [ 56 ], metal alloys [ 57 ], zirconia [ 58 ], bioactive glasses [ 59 ], calcium phosphates [ 60 , 61 ] and glass ionomer resins [ 62 , 63 ]. The release display is time dependent and occurs at a constant rate, thereby representing zero-order kinetics as shown for incorporated Gentamicin sulfate in Figure 5 C.

There are two ways that proteins are stably entrapped in the Diatom skeleton. Jodaikin A. The marine environment is filled with biodiversity that extends into many levels, chemical and structural.

It has been impossible to completely emulate the evolutionary perfected design of natural biomaterials synthetically.

Open in a separate window. Gene modulation of Thalassiosira pseudonana has led to the directed evolution of differently structured Diatoms with stark variations in pore size and patterns of pores [ 78 ]. National Center for Biotechnology Information , U.
