Effervescent cleansers are the most popular immersion cleansers and include alkaline peroxides, perborates and persulphates. Their cleansing action occurs by the formation of small bubbles which displace loosely attached material from the surface of the denture. They are not very effective as cleansers and have a restricted ability to eliminate microbial plaque. Moreover, they are safe for use and do not cause deterioration of the acrylic resin or the metals used in denture construction.[32] Despite this, they are able to cause rapid damage to some short-term soft lining.[36] Discolouration of the acrylic resin to a white denture often occurs, however, this happens because patients do not follow the manufacturer’s instructions and often add very hot water to the cleaning agent.[37][38]
The lower denture's teeth surface is even with the gum surface making the lower plate essentially flat. I mean there is no white tooth higher than the pink gum material. Not knowing the difference and trusting these so called "professionals," I have worn the partials for 8 years now and my bite is so off that my upper and lower front teeth butt against each other and has resulted in wearing them flat, taking the edge off them.
The process of fabricating a denture usually begins with an initial dental impression of the maxillary and mandibular ridges. Standard impression materials are used during the process. The initial impression is used to create a simple stone model that represents the maxillary and mandibular arches of the patient's mouth. This is not a detailed impression at this stage. Once the initial impression is taken, the stone model is used to create a 'Custom Impression Tray' which is used to take a second and much more detailed and accurate impression of the patient's maxillary and mandibular ridges. Polyvinylsiloxane impression material is one of several very accurate impression materials used when the final impression is taken of the maxillary and mandibular ridges. A wax rim is fabricated to assist the dentist or denturist in establishing the vertical dimension of occlusion. After this, a bite registration is created to marry the position of one arch to the other.
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. <<<<
