A two-step functional impression technique for the fabrication of an implant-retained silicone auricular prosthesis

Applications of CAD/CAM Technology for Craniofacial Implants Placement and Manufacturing of Auricular Prostheses—Systematic Review

“…The bone thickness in the mastoid region varies between 2.5 mm and 5.5 mm; therefore, the length of craniofacial implants is usually selected between 3 mm and 5 mm to retain the auricular prostheses [ 10 , 11 ]. Upon osseointegration, CI can be used in combination with various types of retentive attachments (clip bar attachment, magnet attachment, locator attachment, or combination of these types of attachments, i.e., bar with locator attachments or bar with ERA attachment) to retain the auricular prostheses [ 11 , 12 , 13 ].…”

Digital surgical planning and placement of osseointegrated implants to retain an auricular prosthesis using implant software with cone‐beam computed tomography and 3D‐printed surgical guides: A case report

“…Both acceptable 1,3,4,[6][7][8][9][10][11][12][13] and suboptimal outcomes have been reported. 6 Conventional analog approaches used to fabricate implant-retained auricular prostheses involve making a conventional impression of the affected and unaffected ear sites (using the intact ear as an indirect template), 7,14 fabrication of a gypsum-product master cast, 7,[15][16][17] and production of a wax pattern, 7,14,17 used to fabricate the definitive prosthesis via conventional flasking, wax-elimination, and molding and curing of the prosthesis, commonly using silicone. Various modifications of this conventional technique have been described with the objective of overcoming technique-sensitivity hurdles, such as tissue movement, 16 accurate reproduction of convoluted auricular anatomic dimensions with severe undercuts, 14 and impression distortion.…”
