Redesign of a fixture mount to be used as an impression coping and a provisional abutment as well

Abstract

Purpose:An integrated fixture mount/impression coping/ temporary abutment can provide many advantages for immediate loading of dental implants, such as simpler procedure, less chair time, cost reduction, and comfort for the patients.Materials and Methods:A newly designed dental implant fixture mount (DIFMA) can be used as an impression coping for taking an immediate impression. An immediate load provisional prosthesis can then be fabricated shortly after implant placement to immediately load the implants. This fixture mount can also serve as a temporary abutment for immediate chair-side fabrication of provisional prosthesis. Two clinical cases are presented.Results:A clinical case utilizing the fixture mount abutment (DIFMA)/implant assembly is presented. The precision of fitting between the impression copings and implants is secured with this system. The chair time for taking an immediate impression is greatly reduced. Less cost for the restoration is provided and patient comfort is delivered.Conclusions:More patient satisfaction can be conferred by employing the fixture mount in the process of immediate impression taking and as an immediate provisional abutment.

Modification of Fixture Mount to be used as an Impression Coping in Closely Placed Implants

“…In addition, there is no need to purchase a separate impression coping so the cost of restorations can be reduced, which also benefits the patients. Therefore, we can modify the implant fixture mount so that it can be used as an impression coping [7].…”

“…The fixture mounts are removed and connected to the implant analogs, and then the fixture mount-analog assemblies are reinserted in the impression before fabricating the definitive cast [7]. Unscrewing the ball impression screw from the implant when the tray is removed or screwing the matching implant analog in the impression may cause minor movement and thus influence cast accuracy.…”
