<p>A 10-Year Follow-Up of Different Intra-Radicular Retainers in Teeth Restored with Zirconia Crowns</p>

Abstract: Purpose: To evaluate the survival rate in restored teeth with three different types of retainers prior to the fixing of crowns with zirconia through this retrospective clinical study. It is unclear how the type of post and core rehabilitation, and type of resin cement affect the longevity of teeth restored with crowns. Methods: In a private clinic, a total of 101 retainers installed by the same professional between June 2008 and January 2018, with an average time of 58.2 months (4.8 years), were analyzed regar… Show more

“…The use of fiberglass pins (FGPs) has been an alternative to improve the quality of temporary seals intracanal. [ 1 2 , 7 8 ] Among its key features are aesthetic color, do not suffer from corrosion; not require laboratory steps; modulus of elasticity, compressive strength, flexural strength, and thermal expansion are similar to dentin; union chemistry the resin materials; and greater preservation of tooth structure. [ 7 8 9 10 ]…”

“…[ 13 ] This monoblock has great importance, as it provides less risk of fracture of the root remaining relative to metal seals. [ 4 7 ] However, the green fluorescent protein (GFP) modulus of elasticity is approximately 20GPa, whereas prefabricated metal pins have about 97GPa and the dentin has a modulus of elasticity of about 18GPa.

“…Na ocorrência desses casos, pode ser indicada a utilização de retentores intrarradiculares, estes podem ser compostos por diferentes materiais: metal (fundido ou pré-fabricado), fibra de vidro pré-fabricado ou cerâmica (CALABRO DE, et al, 2019). Os retentores pré-fabricados podem ser serrilhados, lisos ou rosqueáveis, além do formato, eles se diferenciam pelo tipo de cimentação, os dois primeiros recebem cimentação passiva, enquanto, o pino pré-fabricado rosqueável tem cimentação ativa, quando comparados o último acaba por produzir certo grau de tensão nas paredes do conduto (OLIVEIRA R, et al, 2018).…”

Entretanto, independentemente de seu formato ou composição, o retentor detém a função de reter o material restaurador coronário que irá receber a coroa protética (CALABRO DE, et al, 2019).…”
