摘要：
An implant (1) having one prosthetic interface (28, 29, 30, 31) in its cervical region (2), one core (22) and at least one thread (23) extending from the cervical region to an opposing apical region (3), wherethe outer diameter (24) of the core (22) decreases in the apical direction (19), and the external diameter (25) of the thread is constant in a first cylindrical portion (13) and decreases in a second tapered portion (12) also in the apical direction (19), where the decreasing rate (10) of the outer diameter of the thread (23) in its tapered portion (12) is greater than the decrease rate (9) of the core diameter (24), the greater height (104, 204) of the thread (23) occurs at the transition point between the cylindrical portion (13) and the tapered portion (12) of the thread, and the width of the thread (4, 5, 6, 7) is greater in the threads (4, 7) close to the cervical (1002) and apical (1003) ends, and smaller in the threads (5, 6) close to the transition point (27) between the cylindrical portion (13) and the tapered portion (12) of the thread (23). It also refers to a thread geometry (23) including semispherical surface cutting edges (40) spaced apart along their entire length.
