Nankali Post And Core Classification
The Nankali post and core classification is the most advanced classification that is used in restorative dentistry for grouping different types of post and cores. Nankali post and core classification Here Nankali post and core classification is illustrated. As it can be observed all systems are divided into main two groups prefabricated (which is made in factories) and those posts that are made in laboratory or in surgeries. In the next step each group is divided into two subgroups according to their counter-sink constructions including their position. In the other steps either the system is symmetrical or non-symmetrical is another important fact that is pointed out. In the Nankali post and core classification the outline surfaces, threaded, smooth and serrated are profoundly discussed, in addition to the other mentioned directions. Because posts can be made from different justified dental materials such as Stainless Steel, Titanium, Titanium Alloy, Gold-Plated brass, Carbon and ...

Restorative Dentistry
Restorative dentistry is the study, diagnosis and integrated management of diseases of the teeth and their supporting structures and the rehabilitation of the dentition to functional and aesthetic requirements of the individual. Restorative dentistry encompasses the dental specialties of endodontics, periodontics and prosthodontics and its foundation is based upon how these interact in cases requiring multifaceted care. This may require the close input from other dental specialties such as orthodontics, paediatric dentistry and special care dentistry, as well as surgical specialties such as oral and maxillofacial surgery. Restorative dentistry aims to treat the teeth and their supporting structures. Many conditions and their consequences may be assessed and treated by a restorative dentist. Environmental causes may include as caries or maxillofacial trauma. Developmental issues may lead to the restorative dentist treating hypodontia, amelogenesis imperfecta, dentogenesis imperf ...

Post And Core
A post and core crown is a type of dental restoration required where there is an inadequate amount of sound tooth tissue remaining to retain a conventional crown. A post is cemented into a prepared root canal, which retains a core restoration, which retains the final crown. The role of the post is firstly to retain a core restoration and crown, and secondly to redistribute stresses down onto the root, thereby reducing the risk of coronal fracture. The post does not play any role in reinforcing or supporting the tooth and can in fact make it more likely to fracture at the root. When deciding whether or not a tooth requires a post and core crown rather than a conventional crown, the following must be established: # Presence of an adequate ferrule (coronal tooth structure) # Sufficient length of canal to retain a post # Curvature and overall anatomy of root canal system # Sufficient root (radicular) dentine thickness for post preparation # Restorability of tooth The benefit of placing ...

Prosthesis
In medicine, a prosthesis (plural: prostheses; from grc, πρόσθεσις, prósthesis, addition, application, attachment), or a prosthetic implant, is an artificial device that replaces a missing body part, which may be lost through trauma, disease, or a condition present at birth (congenital disorder). Prostheses are intended to restore the normal functions of the missing body part. Amputee rehabilitation is primarily coordinated by a physiatrist as part of an inter-disciplinary team consisting of physiatrists, prosthetists, nurses, physical therapists, and occupational therapists. Prostheses can be created by hand or with computer-aided design (CAD), a software interface that helps creators design and analyze the creation with computer-generated 2-D and 3-D graphics as well as analysis and optimization tools. Types A person's prosthesis should be designed and assembled according to the person's appearance and functional needs. For instance, a person may need a transra ...
