[QUOTE="npdynamite, post: 343856, member: 11802"] I wouldnt say there is a maximum ratio, but in general the more "even" things are with zirconia the more even they sinter. So I would look to have the sprues that remain in tact for sintering to be more evenly spaced. Also a large area of pontics on a bridge that is otherwise mostly abutment supported is a likely spot to have a warp. For that reason I would ensure that besides being evenly spaced I would ensure that the spot with the highest likelihood of warping is supported [/QUOTE]
