Intraoral Acrylic Resin Coping Fabrication for Making Interocclusal Records

Abstract

A safe and accurate method for the fabrication of acrylic resin copings to be used for interocclusal registration is described. Copings are fabricated on vital prepared teeth using visible light-cured acrylic resin, and the records are then obtained with autopolymerizing acrylic resin. This allows for an interocclusal recording to be obtained at the final impression 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.…”

Intraoral Registration Coping Formation Using an Interim Restoration as a Matrix

“…Flowable composite resin has been proposed to form registration copings intraorally; 9 however, in everyday clinical reality this is a very technique‐sensitive procedure, because of the handling difficulties presented and the instability of this material. A challenging method has been presented for the direct coping construction 10 . Copings are fabricated from a light‐cured acrylic resin by means of a soft polyethylene matrix.…”

“…A challenging method has been presented for the direct coping construction. 10 Copings are fabricated from a light-cured acrylic resin by means of a soft polyethylene matrix. In the present article, the same acrylic resin has been employed to form the copings, using the shell of an interim FPD as a matrix.…”

Interocclusal Records: A Review.

“…1 An accurate interocclusal record with proper mounting of the casts in an articulator allow the laboratory technician to create proper contours, alignment and clearance of the substructure as well as proper occlusion and intercuspation of the final restoration. 2,3 An interocclusal registration material records the occlusal relationship between the natural and / or artificial teeth for planning occlusal rehabilitation and for construction of removable and fixed partial dentures 4 .…”
