Intraoral Registration Coping Formation Using an Interim Restoration as a Matrix

Abstract

An intraoral procedure for registration coping fabrication is described. The indirectly constructed shell of the interim fixed partial denture is used as a matrix, and a light-cured resin is added directly to form the copings. The proposed technique reduces the total number of clinical sessions and can be useful in cases when tooth preparations and final impressions can be completed at the same appointment.

A Method for Fabrication of Implant-Supported Fixed Partial Dentures

“…A proper fit requires the accurate transfer of the intraoral implant position to the master cast and an exact fit of the impression copings ( Figure 2). 10,16,[20][21][22][23] A precise fit to the abutment can be achieved with electroformed gold copings, which are normally used as the external part of telescoping systems for removable dentures (Figures 10, 19, and 20). Due to their properties, electroformed copings were used in the method presented here to achieve the precise transfer of implant abutment form, angulation, and position in the fabrication of FPDs.…”

“…These include: (1) the correct transfer of the implant position, (2) the correct transfer of vertical height and maintenance of the maxillomandibular relationship, (3) the determination of optimal occlusion, and (4) the correct shaping and angulation of the implant abutments. [1][2][3][4] This case report is presented to introduce a method of restoration with FPDs that allows the transfer of the correct implant position, interocclu-sal relationship, and occlusal recording, as well as the provisional restoration of the implants.…”
