Abstract:
An 18-year-old female patient reported to the Department of Conservative and Endodontics with the chief complaint of fractured tooth with respect to 21 and increased pain and mobility tooth with respect to 22. Intraoral periapical radiograph of 21 revealed coronal loss of tooth structure involving enamel, dentin, and pulp, suggestive of split tooth with respect to 21. Intraoral examination revealed a fracture of coronal structure of 22 and increased mobility in the coronal aspect, suggestive of horizontal crown-root fracture. For management of 21, after endodontic phase, placement of fiberpost, and coronal buildup, intentional reimplantation was done to expose and reattach the vertically fractured root fragment. For management of 22, after endodontic phase, crown lengthening was done, and the fractured fragment was reattached by making it a Natural Richmond's Crown. Radiographs revealed a complete sealing of the fractured fragment and proper positioning of the tooth.

Ionic Bonds
When atoms gain or lose electrons to achieve a more stable electron configuration they form ions. Ionic bonds are electrostatic attractions between ions with opposite charges. Ionic compounds are rigid and brittle when solid and may dissociate into their constituent ions in water. Covalent compounds, by contrast, remain intact unless a chemical reaction breaks them.

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
