Resumo: Objective: Implant-supported overdentures are a valid treatment option for edentulous patients. The use of two mandibular implants is considered the minimum standard of care. This study evaluated the retentive force of two attachments and their respective connection systems in a mandibular implant-supported overdenture. Methods: Two acrylic blocks were prepared: two parallel implants set 22 mm apart were embedded in one of the blocks, while in the other were positioned the female systems for each attachment system tested (Dalbo Ball BTI® and Locator® with female components in both clear and pink nylon). A specific machine was designed to measure the retentive force of the attachments over the cycles applied. The speed of insertion/disinsertion was 0.5 Hz, applied constantly. Results: The clear nylon Locator® attachments registered the highest initial retention value (85.7 N), followed by the Dalbo-Ball® system (62.1 N) and pink nylon Locator® (49.6 N). After 5400 cycles, the mean force exerted was highest in the clear nylon Locator® attachments (42.3 N) followed by Dalbo-Ball® (34.3 N) and pink nylon Locator® (24.6 N). Conclusion: The initial retention force decreases over time for the attachment systems tested.

A utilização de dois implantes mandibulares é considerada o minimum standart of care. Este estudo avaliou a força de retenção de dois sistemas de attachments e seus respectivos sistemas de conexão numa sobredentadura mandibular retida por dois implantes. Métodos: Foram confecionados dois blocos de acrílico: num dos blocos incorporaram-se dois implantes paralelos distanciados de 22 mm; no outro foram instalados os respectivos sistemas fêmea para cada sistema de attachment testado (Bola-Dalbo BTI® e Locator®, com fêmeas em nylon transparentes e cor-de-rosa). Desenvolveu-se uma máquina específica para avaliar a retenção dos attachments ao longo dos ciclos aplicados. A velocidade de inserção/desinserção foi de 0,5 Hz, aplicada de forma constante. Resultados: Os Locator® com nylon transparente foram os que apresentaram maior retenção inicial (85,7 N), seguidos do sistema de Bola-Dalbo® (62,1 N) e dos Locator® com nylon cor-de-rosa (49,6 N). Ao fim de 5400 ciclos, a força média exercida foi mais elevada para os Locator® com nylon transparente (42,3 N) seguido do sistema de Bola-Dalbo® (34,3 N) e, por último, dos Locator® com nylon cor-de-rosa (24,6 N). Conclusão: A força de retenção inicial diminui ao longo do tempo para os sistemas de attachments testados.EDIPUCRS - Editora Universitária da PUCRS2014-07-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Articleapplication/pdfhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/1195010.15448/1980-6523.2014.1.11950Revista Odonto Ciência; Vol. 29 No. 1 (2014); 01-05Revista Odonto Ciência; v. 29 n. 1 (2014); 01-051980-65230102-946010.15448/1980-6523.2014.1reponame:Revista odonto ciência (Online)instname:Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)instacron:PUC_RSenghttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/11950/11775Carvalho, Elsa RodriguesFigueiral, Maria HelenaFonseca, PatríciaVaz, Mário AugustoBranco, Fernando Moraisinfo:eu-repo/semantics/openAccess2015-08-04T18:11:30Zoai:ojs.revistaseletronicas.pucrs.br:article/11950Revistahttps://revistaseletronicas.pucrs.br/ojs/index.php/foPRIhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/oai||odontociencia@pucrs.br1980-65230102-9460opendoar:2015-08-04T18:11:30Revista odonto ciência (Online) - Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)false
