Guidelines for abutment selection
{"Image DocumentName": "Guidelines for abutment selection", "Image ImageDescription": "A case study: Resistance to dislodgement of zirconia copings cemented onto titanium abutments of different heights. Abbo B, Razzoog M, Vivas J, Sierraalta M. J Prosthet Dent 2008; 99: Purpose: Authors measured the force it takes to dislodge a cemented crown on. abutments of various heights. Results: The taller the abutment height the greater the force required to dislodge a cemented crown. Study recommends that abutments should be no less than 4mm in height when using a cemented crown. Abutment height: 6.5mm 5.5mm Average dislodgement force: N N. One other study I would like to share with you before we move on is this article by Razzoog and others. In this article the authors measured the force it takes to dislodge a crown cemented on abutments of various heights. They determined that the shortest height of an abutment should be no less than 4mm. Other wise the crown will fall off too easily regardless of what kind of cement you use.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
