Telescope-assisted combination and attachment cases Telescopic structures can add an additional layer of stability and support in many situations. The telescopes are milled parallel with the path of insertion of the attachments and other milled construction elements. Zero-degree milled bar with locators and friction fit CAD/CAM-milled titanium superstructure: The milled bar and the superstructure are one telescope in function, providing friction fit and load distribution over the entire structure, preventing the locators from becoming load-bearing. The locators are strictly a retentive element, as they should be (Figs. 78 and 79). " Screwmented " telescopic implant bridge: The anterior implant abutments are telescopes; the distal implants are screw-receiving (Figs. 80-83). Full analog workflow: Individual telescopes supporting attachments and zero-degree friction-fit shoulder attachments (Figs. 84-86, p. 62). These are cast gold secondary telescopes welded into the cast partial frame. All the milling and path of insertion is parallel with the attachments.

Implant abutments can be seated as usual or with the help of the seating jig. O n l y t he pr i m a r y c opi n g s g e t cemented; no cement or bonding agent should be used to hold the secondary copings or denture in place-this is 100% friction fit. Do not ever put cement into the secondary copings! All primary copings get cemented simultaneously, then the denture is used to seat these home. Do not cement the primary copings separately; this will negatively affect the fit of the denture and it may never seat properly. dentaltown.com \\ APRIL 2021 DT0421_Mohr_Telescopic-MM.indd 61 61 3/18/21 1:40 PMhttp://www.dentaltown.com
