ABSTRACT:
A device for supporting a dental prosthesis and to provide a rigid engagement to a dental implant or natural dentition while correcting the lack of parallelism of the latter. The device includes an implant abutment that has a spherical portion and an anchorage portion for rigidly mounting to the implant. A tubular engaging assembly supports the prosthesis and includes two ends. At least one of the ends has a diameter that is smaller than the diameter of the spherical portion and sufficiently large to house a substantial area of the spherical portion. A dental surgeon fills the tubular engaging assembly with cement and brings it in contact with the spherical portion. A protuberance with irregularities for enhancing the engagement is introduced in side the tubular engaging assembly. The latter can be positioned in site to correct any lack of parallelism of the implant.
