Hydroxyapatite as a Biomaterial for Dental Restoration

Hydroxyapatite particle (HAp) is a naturally occurring mineral form of calcium apatite, which is predominately obtained in mineralized tissue . Hydroxyapatite is also one of the major components of dentin. Due to its bone-bonding ability, hydroxyapatite has been widely used as a coating material for various dental implants and grafts. Additionally, HAp is highly biocompatible and can rapidly osteointegrate with bone tissue. Due to these advantages, HAp is used in various forms, such as powders , coatings , andcomposites for dental restoration. Despitevarious advantages, hydroxyapatite has poor mechanical properties (highly brittle) and hence cannot be used for load-bearing applications Our Guarantees! • On-time delivery guarantee • PhD-level professional writers • Automatic plagiarism check • 100% Privacy and Confidentiality • High Quality custom-written papers

Anatomy and Development of the Tooth

Anatomy and Development of the Tooth To design advanced biomaterials for dental repair, it is important to understand the chemical and physical properties of native tissues. Teeth are three-dimensional complex structures consist- ing of the crown, neck, and root. Oral ectodermal cells and neural crest–derived mesenchyme are the primary precursors for mammalian teeth. Tooth development can broadly be divided into fi ve major stages: dental lamina, initiation, bud stage, cap stage, bell stage and eruption Our Guarantees! • On-time delivery guarantee • PhD-level professional writers • Automatic plagiarism check • 100% Privacy and Confidentiality • High Quality custom-written papers

Discuss synthesis and fabrication of bioac- tive nanomaterials, examine their current limitations, and conclude with future directions in designing more advanced nanomaterials.

Nanotechnology is emerging as an interdisciplinary fi eld that is undergo- ing rapid development and has become a powerful tool for various bio- medical applications such as tissue regeneration, drug delivery, biosensors, gene transfection, and imaging. Nanomaterial- based design is able to mimic some of the mechanical and structural properties of native tissue and can promote biointegration. Ceramic-, metal-, and carbon-based nanoparticles possess unique physical, chemical, and biological character- istics due to the high surface- to-volume ratio. A range of synthetic nanoparticles such as hydroxyapatite, bioglass, titanium, zirconia, and sil- ver nanoparticles are proposed for dental restoration due to their unique bioactive characteristic. This review focuses on the most recent develop- ment in the fi eld of nanomaterials with emphasis on dental tissue engineer- ing that provides an….
