Biomimetics is an area of research in which the analysis of structures and functions of natural materials provide a source of inspiration for design and processing concepts for novel synthetic materials. Through biomimetics, it may be possible to establish structural control on a continuous length scale, resulting in superior structures able to withstand the requirements placed upon advanced materials. It is well recognized that biological systems efficiently produce complex and hierarchical structures on the molecular, micrometer, and macro scales with unique properties, and with greater structural control than is possible with synthetic materials. The dynamism of these systems allows the collection and transport of constituents; the nucleation, configuration, and growth of new structures by self-assembly; and the repair and replacement of old and damaged components. These materials include all-organic components such as spider webs and insect cuticles (Fig. 1); inorganic-organic composites, such as seashells (Fig. 2) and bones; all-ceramic composites, such as sea urchin teeth, spines, and other skeletal units (Fig. 3); and inorganic ultrafine magnetic and semiconducting particles produced by bacteria and algae, respectively (Fig. 4).

The morphology, chemical composition, and optical properties of long monoaxonic spicules were studied in several species of marine deep-sea hexactinellid sponges of different orders and families: Asconema setubalense (Hexasterophora, Lyssacinosida) and Monorhaphis chuni Schulze (Monorhaphiidae). Their macrostructural organization is a system of thin layers laid around the central cylinder containing a square canal filled with organic matter. A significant role in spicule organization is played by the organic matrix. The macrostructural of organization of the spicule in Monorhaphis chuni is a system of the “cylinder-within-a-cylinder” type. However the spicule surface is covered with ridges. They penetrate a few layers into the spicule. Analysis of the elemental composition of the basalia spicule of Monorhaphis chuni demonstrates a heterogeneous allocation of C, O, Si on the spicule surface, subsurface layers, and on ridges. All studied spicules have the properties of anisotropic crystals and they demonstrate a capability to the birefrigence. On the other hand we discovered unique property of spicules—their capacity for triboluminescence. The discovery of triboluminescence in composite organosilicon materials of which the spicules of hexactinellid sponges are built may contribute to the creation of biomimetic materials capable of generating light emission.

Dental implants are used broadly in dental clinics as the most natural-looking restoration option for replacing missing or highly diseased teeth. However, dental implant failure is a crucial issue for diabetic patients in need of dentition restoration, particularly when a lack of osseointegration and immunoregulatory incompetency occur during the healing phase, resulting in infection and fibrous encapsulation. Bio-inspired or biomimetic materials, which can mimic the characteristics of natural elements, are being investigated for use in the implant industry. This review discusses different biomimetic dental implants in terms of structural changes that enable antibacterial properties, drug delivery, immunomodulation, and osseointegration. We subsequently summarize the modification of dental implants for diabetes patients utilizing carbon nanomaterials, which have been recently found to improve the characteristics of biomimetic dental implants, including through antibacterial and anti-inflammatory capabilities, and by offering drug delivery properties that are essential for the success of dental implants.

Indications for endodontic surgery include failed nonsurgical treatment or retreatment, anatomical problems or iatrogenic errors. Endodontic surgery was considered as the last option with instruments that were unsuitable, surgical sites with inadequate vision and increased incidence of post-operative complication. But today endodontic surgery has evolved into endodontic microsurgery with the advancement in illumination, magnification, instruments and materials. Higher magnification and micro-instruments have increased the clinical outcome of endodontic surgery. Traditional instruments used in endodontic surgery are too large for the small osteotomy sites of microsurgery. Few of the instruments used for microsurgery are the smaller version of the traditional instruments. Endodontic microsurgery represents a minimally invasive treatment option with predictable outcome with the use of micro-instruments. A high success rate of nearly 93.5 % is reported, thus, making microsurgery a predictable option for the management of periapical pathology where surgical root treatment is not possible. The advanced techniques developed to overcome the barriers seen in traditional endodontic surgery have allowed the clinicians to achieve higher success rates. Along with the micro-instruments, the introduction of biomimetic materials has also led to the favourable results after endodontic surgery. This article discusses the different microsurgical instruments available for microsurgical procedures. KEY WORDS Curette, Microblade, Microsurgery, Piezotomes, Retractor, Ultrasonic.
