Support is the principle that describes how well the underlying mucosa (oral tissues, including gums) keeps the denture from moving vertically towards the arch in question during chewing, and thus being excessively depressed and moving deeper into the arch. For the mandibular arch, this function is provided primarily by the buccal shelf, a region extending laterally from the back or posterior ridges, and by the pear-shaped pad (the most posterior area of keratinized gingival formed by the scaling down of the retro-molar papilla after the extraction of the last molar tooth). Secondary support for the complete mandibular denture is provided by the alveolar ridge crest. The maxillary arch receives primary support from the horizontal hard palate and the posterior alveolar ridge crest. The larger the denture flanges (that part of the denture that extends into the vestibule), the better the stability (another parameter to assess fit of a complete denture). Long flanges beyond the functional depth of the sulcus are a common error in denture construction, often (but not always) leading to movement in function, and ulcerations (denture sore spots).
Custom-made porcelain dentures are crafted to look like your natural teeth (or an improved version of your natural teeth). Great care is taken to design and fabricate a set of teeth that not only look natural, but also complement the size and shape of your mouth. Dentists may first create wax versions of the dentures so patients can try on their new teeth on before the final dentures are made; this process allows for design modifications and fit adjustments that can be applied to the final set of dentures.
Throughout your lifetime, dentures will need to be replaced and adjusted which can become time consuming and expensive. It is a simple fact that dentures start to become loose and can break through normal activities such as talking, eating, etc. If a denture arch breaks, it may be possible to repair but in some cases it will need to be replaced entirely.
Dr. Okunuga’s dental center has an on-site dental lab that fabricates new dentures and provides repairs and relines, often with same-day service. Being able to provide dentures in a day is a significant advantage, especially for patients who have traveled far distances. The on-site lab also eliminates the need to use outside commercial labs, which helps keep our fees low.
Later that afternoon I came back to have 16 teeth extracted. I got to the office and waited about 30 minutes before I was seen. I got to the back and began injections. After this I went to a full blown panic attack and came close to passing out. The one positive is the dentist who was working on me took it in stride. I wasn't treated disrespectfully and after about 30 minutes the panic subsided and she was able to finish my injections and begin pulling teeth.
