“…U većem broju studija beleže se češće frakture korena kod zuba ojačanih metalnim kočićima nego kod onih ojačanih fiberglas kočićima 46 . Krutost materijala, korozija, decementiranje, koncentracija sila i mikropropuštanje 49 predstavljaju razloge za neuspeh metalnih kočića.…”

Introduction: Diseases of the pulp and periapical tissue, which require endodontic treatment, are often accompanied by a large tooth crown defect caused by caries. Regardless of well-performed endodontic treatment, endodontically treated teeth are prone to fractures. This raises the issue of tooth restoration after quality endodontic treatment. Crowns represent dental restorations, made of ceramics or metal-ceramics, which, in addition to establishing the morphology of the teeth, also have the function of protecting teeth with a larger crown defect. The aim was to review the factors that could lead to the fracture of endodontically treated teeth. Conclusion: When deciding whether to restore an endodontically treated tooth with crowns, it is necessary to consider several factors, among which are the loss of hard tooth tissue, the structure of the endodontically treated teeth, the forces to which the teeth are exposed in the oral cavity, the instruments and materials used during the endodontic treatment, as well as the aesthetics of the endodontic treated teethProsthetic reconstruction with a crown proved to be significant in the protection of posterior endodontically treated teeth, while treatment of the front teeth with crowns is indicated for the teeth with major damage and aesthetic defects that cannot be repaired by other conservative procedures.

“…There is a constant occlusal load on all the teeth during all functions of the oral cavity. These forces intend to damage dental restoration (Bessone and Bodereau, 2010). Post, therefore, helps in distributing equal amounts of forces in endodontically treated teeth.…”

A root canal treatment will have a loss of coronal and radicular tooth structure. This will affect the anchorage of the teeth. Therefore, post- retained crowns are indicated to prevent fracture. The study aims to associate age, tooth-related and gender distribution in patients undergoing prefabricated metal post after root canal treatment. The details of the 86,000 patient records were reviewed and analysed from DIAS (dental information archiving system), out of which 451 case records of the patients who underwent prefabricated posts after root canal treatment were retrieved. The collected data were cross-verified and compiled together in an excel sheet. Compiled data were statistically analysed with the help of SPSS software (23.0). In this study, we can contemplate that there is a significant association between age and type of teeth underwent prefabricated metal posts, l8-30 yrs of age group patients had more posts after root canal treatment compared with other age groups (p<0.05). On comparing the gender to the type of teeth which had posted after root canal treatment, female patients had more number of posts compared to male patients. There is a significant difference seen (p < 0.05). Within the limitations of the study, maxillary premolars are predominantly used prefabricated metal post in females. Mandibular molars are commonly treated among male patients and maximum metal post are given after root canal treatment in less than 40 years of age as the masticatory forces are more, so to support the remaining tooth structure rigid posts are required after root canal treatment.

“…Nevertheless, experimental results (necessary to compare the numerical counterparts) are very scarce due to the laboratory techniques used to analyze the mechanical behavior of sound or restored teeth are not very precise. The difficulties of using experimental or "in vivo" methods are the complexity of teeth geometry, the laboratory equipment exactness, the different involved materials, the different load modes, and the little availability of teeth extraction and patient participation [2][3][4][5][6][7][8][9][10]. On the contrary, FEA allows the creation of complex 3D models under complex load and boundary conditions schemes including direct restoration (amalgam and composite resin) and indirect restoration (dental crown or fixed partial prosthesis).…”

Un modelo tridimensional para caracterizar sistemas dentales en sus diferentes condiciones funcionales, geometría y modos de carga fue desarrollado mediante el código de elementos finitos ABAQUS. Los resultados del modelo fueron utilizados para evaluar cuantitativamente la magnitud y distribución de las relaciones esfuerzo-deformación-desplazamiento en especímenes sanos y restaurados con postes intrarradiculares prefabricados (cónicos y cilíndricos). Bajo las mismas condiciones de carga y contorno, se observaron diferencias en esfuerzos, desplazamientos y deformaciones elásticas en especímenes agujereados, de corona esmaltada, y reforzados con postes cónicos y cilindricos. Se encontró que el poste de fibra de vidrio con geometría cilíndrica minimiza de mejor manera la magnitud de los esfuerzos, desplazamientos y deformación elástica en dientes premolares. Los resultados indican que la metodología de los elementos finitos es adecuada y conveniente para evaluar esfuerzos, desplazamientos y deformaciones elásticas en ortodoncia.
