An In Vitro Analysis of the Physical and Mechanical Behavior of a PEEK Component for an Implant-Supported and Retained Removable Dental Prosthesis

Factors influencing retention and durability of attachments for overdentures – adverse effects of cleansings, pH, and temperature: A systematic review

“…Among the attachments analyzed is the Locator with six studies [ 10 , 11 , 13 , 14 , 16 , 23 ], bar/clip with three [ 12 , 15 , 21 ], magnetic [ 17 ] with one, and a new model of o'ring for the ball attachment with four [ 7 , 22 , 26 , 27 ]. The most analyzed cleansing solutions were NaOCl [ 7 , 11 , 12 , 13 , 15 , 16 ], followed by different alkaline solutions with different commercial brands [ 7 , 10 , 11 , 12 , 13 , 15 , 16 ] with more details found in Table 2 .…”

“…Two studies evaluated the effect of pH [ 17 , 21 ] on attachments. One study evaluated the simulation of the effect of saliva [ 14 ] and five studies evaluated the effect of aging on attachments [ 17 , 22 , 23 , 26 , 27 ].…”

“…For the criterion “were outcomes measured in a reliable way”, twelve studies [ 7 , 10 , 11 , 13 , 15 , 16 , 17 , 21 , 22 , 23 , 26 , 27 ] showed a high risk of bias. This is because the studies did not declare by how many authors, if they were trained, or if there was blinding regarding the analyzes performed.…”

“…However, the use of solutions and immersions for denture cleaning presents problems such as discoloration, corrosion, and loss of retention of the attachments used [ 12 , 17 , 18 ], the latter is the most common problem with overdentures [ 19 , 20 , 21 , 22 ], which have salivary composition, different temperatures, and pH to which the oral cavity is subjected during food intake as factors associated with loss [ 14 , 17 , 21 , 23 ].…”

Efeitos dos métodos de higienização mecânicos e químicos na cápsula de o\'ring de overdenture

“…Correlação entre a força de retenção e a alteração dimensional dos diâmetros. A higienização das overdentures é indispensável para longevidade do tratamento reabilitador e apresenta como obstáculo a composição das próteses por diferentes materiais (BONACHELA et al, 2003;VARGHESE et al, 2007;NGUYEN et al, 2010;YOU et al, 2011;RUTKUNAS et al, 2011;WATCHARAPICHAT et al, 2014;DERAFSHI et al, 2015;KÜRKCÜOGLU et al, 2016;ALGRAISI et al, 2018;KHODADADKASHIP et al, 2019;AYYILDIZ et al, 2020;FELIPUCCI et al, 2020;VALENTE et al, 2021). O método mecânico (escovação) é o método mais utilizado pelos pacientes para higienização de próteses totais (DILLS et al, 1988;PARANHOS et al, 2007;PERACINI et al, 2010;ARRUDA et al, 2017).…”
