Dentists' Perspective and Experiences Relative to the Accidental Dropping of Implant Drivers and Components Intraorally: A Survey of Practicing Clinicians.

Ingestion or aspiration of dental implant screwdrivers or implant components is potentially life-threatening. There are no reports on the frequency at which dentists drop these devices within the mouth or which components are most problematic. There are few reports on what protective measures clinicians take, where risks exist, and how this problem is managed.

A technique to guide replacement of multiunit abutments supporting an existing implant-supported fixed complete denture.

This article describes a technique for replacing a fractured multiunit abutment (MUA) supporting an existing implant-supported fixed complete denture (ISFCD) with a custom-fabricated abutment alignment device. The angulated MUA threads that receive the prosthetic screw to secure the ISFCD can become stripped, cross-threaded, or, in some patients, the thin metal in this region may fracture. These conditions necessitate the removal and replacement of the angulated MUA.

A technique to eliminate subgingival cement adhesion to implant abutments by using polytetrafluoroethylene tape.

Residual excess cement adhered subgingivally to an implant abutment has the potential to cause periimplant mucositis or periimplant disease. This article describes a procedure in which polytetrafluoroethylene (PTFE) tape is used to protect dental cements from adhering to the implant abutment. This technique ensures complete removal of cement from the implant abutment after seating of the crown.
