Effect of different implant angulations and insertion-removal cycles on the retentive force of zirconia and coated titanium denture attachments: An in vitro study.
Coated titanium denture attachments have been studied to ensure adequate retention. However, studies on the retentive force of zirconia denture attachment under different implant angulations and insertion-removal cycles are lacking. The purpose of this in vitro study was to evaluate the effect of di...

However, studies on the retentive force of zirconia denture attachment under different implant angulations and insertion-removal cycles are lacking. The purpose of this in vitro study was to evaluate the effect of different implant angulations and insertion-removal cycles on the retentive force of coated titanium and zirconia denture attachments. Nine patrix blocks and 9 matrix blocks were equally divided into 3 denture attachment groups: 2 coated titanium attachments (LOCATOR and LOCATOR R-Tx) and 1 zirconia attachment (Zeramex Docklocs patrix). Each attachment group was subdivided into 3 subgroups based on implant angulation (0-, 15-, and 30-degrees) (n=8). Each specimen underwent up to 3240 cycles of denture insertion-removal. Retentive force was measured 5 times and averaged at insertion-removal cycles of 0, 270, 540, 810, 1080, 2160, and 3240. Data were analyzed by using 3-way repeated measures ANOVA (α=.05). Significant interactions were observed among denture attachment, implant angulation, and insertion-removal cycle (P <.001). In the 0-degree group, retentive forces among all attachments demonstrated no significant differences (P >.999), while, in the 15- and 30-degree groups, retentive forces among all attachments demonstrated significant differences (P <.001). Comparing implant angulations, the retentive force in the LOCATOR R-Tx group exhibited no significant differences (P >.999), while the retentive force in the LOCATOR and Zeramex Docklocs groups exhibited significant differences (P <.001). The retentive force in each attachment group tended to decrease as insertion-removal cycles increased (P <.001). The Zeramex Docklocs zirconia denture attachment provided retention similar to that of the coated titanium attachments at 0-degree implant angulation; however, at 15- and 30-degree implant angulations, the LOCATOR attachment provided the greatest retention, followed by Zeramex Docklocs and LOCATOR R-Tx. Implant angulation up to 30 degrees affected the retention of the LOCATOR and Zeramex Docklocs attachments, while it did not impact the retention of the LOCATOR R-Tx attachment. Retention decreased over time in both zirconia and coated titanium attachments. pubtype: Academic Journal doctype: research Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
