should it take this long????

[missmolly]

monday will be six weeks since i had impressions done for my refinements on the bottom and my aligners are still not here..is this normal?? when they did the impressions they told me it would be about three weeks until they are here, well we are double that and they are still not here..i cant get any info from the dentist the last time i was there was 2 weeks ago and he said "i should be getting them any day now" well that was 2 weeks ago..i have an appointment on monday for impressions for my upper refinement so i better get some answers then about what is going on...i hope i dont have to wait this long for my uppers too...anyone else had to wait so long for refinement trays??? my whole case was 15/u and 11/l and after my first set of impressions all my aligners were here in 4 weeks..so why are a few refinement trays taking so long??? im wondering if invisalign sent a new clin check to the doc and they are waiting for approval from him and he has not checked his mail or something...i could totally see him doing something like that...sorry for the long post but any feedback would be appreciated i just feel like so much waisted time is going by with no movement..
