“…Coral-based bone substitutes are predominantly composed of calcium carbonate used either in its naturally occurring form or processed by heat treatment with ammonium phosphate and converted into crystalline HA which subsequently has minimal residual carbonate [ 3 , 10 , 71 , 72 ]. HA is a natural polymer of calcium phosphate obtained from bone or natural materials, such as coral, and widely used to promote bone healing due to its ability to act as a structural scaffold.…”

After tooth loss, bone resorption is irreversible, leaving the area without adequate bone volume for successful implant treatment. Bone grafting is the only solution to reverse dental bone loss and is a well-accepted procedure required in one in every four dental implants. Research and development in materials, design and fabrication technologies have expanded over the years to achieve successful and long-lasting dental implants for tooth substitution. This review will critically present the various dental bone graft and substitute materials that have been used to achieve a successful dental implant. The article also reviews the properties of dental bone grafts and various dental bone substitutes that have been studied or are currently available commercially. The various classifications of bone grafts and substitutes, including natural and synthetic materials, are critically presented, and available commercial products in each category are discussed. Different bone substitute materials, including metals, ceramics, polymers, or their combinations, and their chemical, physical, and biocompatibility properties are explored. Limitations of the available materials are presented, and areas which require further research and development are highlighted. Tissue engineering hybrid constructions with enhanced bone regeneration ability, such as cell-based or growth factor-based bone substitutes, are discussed as an emerging area of development.

“…In the past 50 years, calcium phosphate for daily oral care has been thoroughly researched, especially in preventative dentistry. HA can be extracted from various natural resources such as bovine, ovine, porcine bone and marine structures [12][13][14][15][16]. Trace elements such as zinc, sodium, magnesium and carbonate present in some natural sources of HA have been found to mimic the apatite produced from human bone and influence the physical properties of HA such as crystal structure, morphology and solubility, and also the thermal stability [4].…”

Calcium phosphate compounds form the inorganic phases of our mineralised tissues such as bone and teeth, playing an important role in hard tissue engineering and regenerative medicine. In dentistry and oral care products, hydroxyapatite (HA) is a stable and biocompatible calcium phosphate with low solubility being used for various applications such as tooth remineralisation, reduction of tooth sensitivity, oral biofilm control, and tooth whitening. Clinical data on these products is limited with varied results; additionally, the effectiveness of these apatite compounds versus fluoride, which has conventionally been used in toothpaste, has not been established. Therefore, this review critically evaluates current research on HA oral care, and discusses the role and mechanism of HA in remineralisation of both enamel and dentine and for suppressing dentine sensitivity. Furthermore, we position HA’s role in biofilm management and highlight the role of HA in dental applications by summarising the recent achievement and providing an overview of commercialised HA dental products. The review also indicates the existing limitations and provides direction for future research and commercialisation of apatite-based oral care products.

“…In another study by Shavandi et al (2016), waste kina shells were converted into hydroxyapatite with preserved porosity and interconnected porosity structure without addition of any other matrix. The process started with boiling and cleaning the kina shells from soft tissue and spine fragments.…”

This chapter explored the synthesis method of macro porous ceramic by using the partial sintering, direct foaming, replica template and sacrificial template technique. The focus is to produce macro porosity in the ceramic for specific application purposes that required this porosity range. At first, fundamentals in each technique were discussed and the advancement in the topic for the recent five years was presented. This is followed by advantages and limitations existing with the current technology for each synthesizing technique. Finally, the chapter covers the possible future trends that can be explored in making the process of synthesizing macro porous ceramic to be more repeatable, stable and sustainable in the near future.
