[QUOTE="Tero, post: 45451, member: 4267"] 1 piece zr abutments are not problem if you know what are you doing and if you have right kind of screw. It is allso important how manufacture these abutments and what kind of machine is used. It is truth that zr abutments can failure in cases that Ti abutments will stand. But, zr abutments won't break by itself. Think about it this way. In case that zr abutment will break for exsample becouse of bad impression with wrong implantposition, Ti abutment will bend. This can cause lot of more problems to implants. When you have hi-quality zr abutments and everybody in team knows what to do, no problem. About of strenght of zr abutments,for exsample custom made Astra 4.5-5.0 (lilac)zr abutment can take more than 1400N force in 45 degree angle. (Turku University pilot test, made in Finland) Who can bite this to pieces? :cool: [URL=http://imageshack.us/photo/my-images/27/abutments.jpg/][attach=full]8960[/attach][/URL] Uploaded with [URL=http://imageshack.us]ImageShack.us[/URL] [ATTACH=full]8960[/ATTACH] [/QUOTE]
