RESUMEN
This dental technique described assists the clinician with determining the maxillary midline and for the maxillary midline to coincide with the facial midline. This is accomplished during the acquisition of a facebow registration which is often utilized during prosthetic rehabilitation.
RESUMEN
The purpose of this article is to describe a technique to accurately cement implant crowns on an abutment extraorally and prevent misalignment that might change the desired position of the crown on the abutment when delivered. An implant-retained crown was tried-in and occlusal and interproximal contacts were adjusted for delivery. The cementation verification aid was fabricated using a polyvinylsiloxane bite registration material (Blu Mousse) to cement the crown onto the abutment extraorally to ensure proper alignment of the crown on the abutment. Cementation of the prosthesis occurred with no adjustments required to the interproximal or occlusal contacts during final delivery. This article provides a technique that aims to increase accuracy in the placement of the crown on the abutment when cementing screwmentable crowns.
RESUMEN
Bacterial recontamination of the empty space is of concern in the time between the post space preparation and cementation of a cast post-and-core. This dental technique describes a novel treatment approach with sterilized polytetrafluoroethylene tape and a reinforced zinc-oxide eugenol restorative material to maintaining asepsis of the root canal space while awaiting fabrication and delivery of a cast post-and-core. On delivery of the cast post-and-core, the material can be removed with minimal time and effort.
RESUMEN
Preventing retained cement around implant-retained crowns is crucial for the long-term health and success of the implant. Residual subgingival cement is strongly associated with peri-mucositis and can lead to peri-implantitis. This clinical technique utilizes a 3D printed model of a custom abutment to seat the implant crown on before cementing intra-orally to extrude excess cement. The technique aims to limit the amount of retained cement at the crown-abutment margin and also takes into consideration the cement space already designed into the crown-abutment complex.
RESUMEN
Provisional restorations are required in fixed prosthodontics to protect a prepared tooth until a definitive restoration can be delivered. A patient sought treatment at a prosthodontics practice to replace a missing provisional crown until definitive treatment could be performed once the patient returned from a field exercise. This case report describes a novel way to provide a provisional restoration when other techniques are not feasible, which can be utilized in the clinic or in an austere environment.
