“…Similar elastic properties of different components of the restoration i.e., adhesive system, luting agent, post material and dentin allows for a homogenous stress distribution to the tooth and surrounding tissues, thus providing a protective effect and favoring the integrity of weakened roots. [1][2][3][4][5][6][7] Fiber posts are chemically inert and non-toxic, can be easily removed in failure cases, has Better light conductivity, high fatigue resistance, low electrical conductivity, resistance to solubility, and resistance to biochemical degradation. 8 Pulp cavity of the maxillary central incisor is widest cervically where the pulp chamber shape is triangular and pulp canal appears to be rounder at the midroot and apical level.…”

Customizing the prefabricated fiber post to direct anatomic post possesses advantages of intimate adaptation of the cast metal post and similar modulus of elasticity of prefabricated fiber post, thus optimizing the properties of both. This report presents the case of a 30-year-old female patient with a grossly decayed upper right central incisor having a history of intermittent pain and swelling since 2 weeks. Patient presented with a history of trauma 2 years back and recurring sinus formation since 6 months. A diagnosis of chronic periapical abscess was established and the endodontic treatment followed by direct anatomic post and crown were recommended for the affected tooth. One year conclusive outcome of the presented case highlights that customizing the prefabricated fiber post is relatively simple, minimally invasive and requires only few additional steps in single appointment beyond those needed to lute a prefabricated fiber post.

“…CoCrWMo) (Dewangan & Shrivastava, 2012;Habibzadeh et al, 2017). O titânio e as suas ligas possuem uma alta resistência à corrosão e biocompatibilidade associados a uma alta resistência mecânica (Bueno et al, 2012;Moyin et al, 2019). Materiais com propriedades mecânicas deficientes aumentam o risco de falhas em regiões com acentuada carga oclusal, como as encontradas em pacientes com hábitos parafuncionais (ex.…”

Retenção intracanalar na reconstrução coronária de dentes tratados endodonticamente – uma revisão narrativa

et al. 2020

Considerando o desempenho a longo prazo dos dentes tratados endodonticamente, são vários os fatores que podem conduzir ao insucesso, especialmente em estruturas dentárias com perda tecidual severa. O objetivo do presente trabalho foi realizar uma revisão narrativa da literatura relativa aos diferentes retentores intracanalares para reconstrução coronária de dentes tratados endodonticamente. Os resultados encontrados apontam para a importância da manutenção de estrutura dentária a nível coronário no sucesso clínico a longo prazo. O tratamento endodôntico e a seleção de retentor intracanalar são determinantes para o prognóstico a longo prazo. Apesar da evolução dos materiais e técnicas adesivas nos últimos anos, há limitações mecânicas e geométricas dos materiais retentores intracanalares para compensar a perda de estrutura dentária. Como consequência, falhas clínicas levam a situações de re-tratamento ou perda de elementos dentários com desconforto e maior custo aos pacientes.

Background and Aim: This study aimed to assess the effect of G-Bond and Z-Prime Plus on fracture resistance of prefabricated zirconia posts bonded to root canal walls. Materials and Methods: This in-vitro experimental study evaluated 22 mandibular premolars with equal diameter and length. The teeth were cut at the cementoenamel junction (CEJ), underwent root canal treatment, and were randomly divided into two groups (n=11). One tooth from each group served as a control. Post space was prepared in the remaining teeth with a 10-mm length. Intracanal dentin was then etched, rinsed, and dried. Panavia F2 resin cement was applied to the canal. Z-Prime Plus and G-Bond were applied to the surfaces of zirconia posts in groups 1 and 2, respectively, and the posts were then cemented into the canals. The cores were built-up using Photo Core resin composite. The teeth underwent a compressive force applied to the central fossa of the core along their longitudinal axes at a crosshead speed of 0.5 mm/minute. The load at fracture was recorded. Data were analyzed using t-test considering their normal distribution. Result: The mean fracture resistance was 1094.2±328.0 N with G-Bond and 912.6±373.0 N with Z-Prime Plus; the difference was not significant (P=0.4). Conclusion: G-Bond and Z-Prime Plus were not significantly different in fracture resistance of zirconia posts bonded to root canal walls. However, G-Bond is recommended for this purpose since it had a lower coefficient of variation (CV) and slightly higher fracture resistance.
