Description

  The present invention relates to a dental implant fixture mount and a driver thereof.

  Traditionally, in most dental implant systems, fixture mounts are used for fixed placement of dental implants. After the dental implant is placed, the fixture mount is removed and disposed of immediately. Three to six months after placement of the dental implant, a conventional impression coping and coping screw are used to produce the plaster model required for restoration. This is not only a waste of time, but a waste of fixture mount material.

  It also requires fixture mounts, impression copings, coping screws, pre-made or customized abutments to prepare dental restorations, which are not only expensive and time consuming, but also in clinical use Is also inconvenient.

  Related arts include Patent Documents 1 to 3 and the like, but there is no fixture mount for a dental implant that is inexpensive and easy to use.
