Extra oral cementation of implant prosthesis: a case report.

Extraoral cementation is a technique that utilizes a stock abutment and a laboratory fabricated crown that is cemented extra orally; the advantage of this technique is that the retained excess luting agent during intraoral cementation, which can be a source of bacterial retention and cannot be observed radio graphically and is not possible to remove with explorer all the time, does not get accumulated and can be trimmed off easily before the final placement of the crown. Thus this technique allows no retention of luting cement, providing better soft tissue contours, no soft tissue inflammation, no retention of plaque and no bone loss. In short it prevents implant failure related to retained cement around implants. This technique provides overall health of peri-implant soft tissues as compared to conventional technique of crown placement where cement retention is a common problem, leading to implant failures.
