It was our impression from viewing the video that this technique is very dependent on the dentist's skill in performing the needed steps (more so than with conventional construction, primarily due to time constraints needed to accomplish certain steps, and accomplish them the first time, properly, before the denture materials set). So in that regard, likely the dentist who fabricated your mother's denture is due as much credit as the system itself.
We paid for extraction and dentures and it was for 2 sets one to wear until gums heal and so we did but it took so much time because they said not ready on gums. This went on & on and then they would NOT answer their phone when we called for the permanent set (we paid for) and they would not return messages. So 2 years have gone and I am left with the first set used until gum set and they are awful and this place is in Odessa, Texas. They are cheats and liars.
The front office has been great in terms of explaining processes, scheduling, and billing. I've also had to coordinate paratransit to get my mom to the office, and they've worked with me on times to make sure everything lines up right. Something you can probably only appreciate if you've been in a similar situation. They've also worked with us on fixing issues and missed appointments due to unforeseeable circumstances. Not only did they not scold us for missing an appointment, but they worked with me to resolve the problem that caused it- my mom's assisted living facility biffed it and didn't give her pain medicine after her surgery. :/ But, like I said, this office came through and helped- always making her care the top priority.
The office people and assistants must be low wage workers. They have the typical low paid, high stress lack of concern for the patient. The person who did my form did not do it well. That was evidenced in the quality of the temporary denture. The Dentist who did the extractions was the absolute best dentist I have ever seen in my 55+ years. They give you a pill to take an hour before you get there and if needed, one when you arrive. It relaxes you and one was enough for me. I was ready to go to sleep. They took me straight in and the dentist took 20 minutes numbing every tooth with a local anesthetic. <<<<Dentures
