Highly Upset: Hoping they would do better. I am retired from Navy 20 years , and working with Private Dental Office 15 years. with 9 years as Dental Asst., Dental Hygiene and 26 years as Dental Laboratory Technician trained and Highly experienced. So, I am not speaking from the lack of experience or knowledge. This is not enough room to tell it all in brief I WOULD NEVER RECOMMEND ASPEN to friend or enemy. More concerned about time than quality, left sharp edges, no inter proximal contacts, terrible prosthetics User's recommendation: Don’t be a future customer, not worth the money.
