Metal structure that serves as an internal support to a dental prosthesis, comprising at least two support posts (1) designed to be attached on respective dental implants (10), and at least one rod (3) for connecting two adjacent support posts (1), where at least one support post (1) comprises at least one protruding element (4a, 4b) that projects from its side, and at least one rod (3) that comprises a first end (5) provided with a blind hole (6) designed to receive a first protruding element (4a) of a support post (1), thus providing an articulated connection that acts like a ball joint, and a longitudinal recess (7) designed to receive a second protruding element (4b) of the adjacent support post (1). This structure is easy to prepare and to assemble.作用成假牙的內部支撐件之金屬結構,包括有設計用以被接合於各自的假牙植體(10)上之至少二支撐柱(1),以及用於連接二鄰接的支撐柱(1)之至少一桿體(3),其中至少一支撐柱(1)包括由其側邊突出之至少一突出元件(4a,4b),且至少一桿體(3)包括具有盲孔(6)的第一端(5),該盲孔(6)係設計用以收容一支撐柱(1)之第一突出元件(4a),從而提供如球窩接頭般作動的活動軸接,以及一縱向凹槽(7)設計用以收容一鄰接的支撐柱(1)之第二突出元件(4b)。這種結構是很容易準備和組裝的。1‧‧‧支撐柱2‧‧‧縱向軸線3‧‧‧桿體4a‧‧‧(第一)突出元件4h‧‧‧(第二)突出元件5‧‧‧第一端6‧‧‧盲孔7‧‧‧縱向凹槽8‧‧‧第二端9‧‧‧凹槽
