Abstract:
1. A compound angular joint for connecting an abutment to a dental implant in a predefined angle, the compound angular joint comprising: a basal member having a first length axis and comprising a basal member distal inner thread having a second length axis; and an apical member comprising an apical member distal inner thread, and a proximal outer thread corresponding to the basal member distal inner thread and exhibiting the second length axis upon connection thereto, wherein the apical member distal inner thread has a smaller diameter than the proximal outer thread, wherein the basal member has a hole having a predefined shape and going through the basal member, such that the basal member has an inner surface, wherein the hole allows proximally connecting the basal member to the dental implant by inserting an implant connector through the hole and connecting the implant connector to the dental implant, and wherein the basal member distal inner thread is located distally on the inner surface, and comprises at least two complete windings, wherein the predefined shape is selected such that it allows fastening the basal member to the dental implant by the implant connector, wherein the apical member distal inner thread is arranged to connect the abutment by an abutment connector distally to the apical member, wherein the apical member distal inner thread comprises at least two complete windings, such that the at least two complete windings allow securing the abutment to the apical member by the abutment connector, wherein the second length axis forms the predefined angle to the first length axis, and wherein the compound angular joint allows implanting a tooth prosthesis at the predefined angle wherein the predefined angle is smaller than 180° in respect to the dental implant.
