Crown cementation and pulpal health

Crown cementation A wide range of cementation forces have been used in many studies ranging from a minimum of 22 5 N (Wang et al 1992) to a maximum of 700 N (Moore et al 1985) With such an extensive range of forces documented it is not certain what constitutes a relevant force clinically

Extraoral Cementation of Implant Crowns

After cementation to the stock abutment the laboratory-fabricated crown will support and shape any gingival tissue coronal to the restorative margin on the abutment Intraoral cementation of the crown to the abutment has the possibility of cement retention which can be biologically injurious to the soft tissue and bone surrounding the implant
