Generally speaking partial dentures tend to be held in place by the presence of the remaining natural teeth and complete dentures tend to rely on muscular co-ordination and limited suction to stay in place. The maxilla very commonly has more favorable denture bearing anatomy as the ridge tends to be well formed and there is a larger area on the palate for suction to retain the denture. Conversely, the mandible tends to make lower dentures much less retentive due to the displacing presence of the tongue and the higher rate of resorption, frequently leading to significantly resorbed lower ridges. Disto-lingual regions tend to offer retention even in highly resorbed mandibles, and extension of the flange into these regions tends to produce a more retentive lower denture. An implant supported lower denture is another option for improving retention.
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
