The Art and Science of Creating Well-Fitting Dentures
Even with modern knowledge about oral health and how to prevent tooth decay and gum disease, more than 25 percent of Americans have lost all their teeth by the time they are 65. Perhaps they did not have access to dental education, quality care or treatment. Whatever the reasons, those who suffer from “edentulism” — the complete loss of all permanent teeth — also suffer from poor self-image, impaired nutrition, and reduced quality of life.
Removable full dentures are often the solution of choice for those suffering from edentulism. Dentures can be made to look good and feel great; but successful denture-wearing demands the collaboration of a skilled dentist and a willing patient.
A set of well-fitting full removable dentures starts with detailed planning. We need to work out where each tooth will be placed and how the upper and lower teeth will meet together. To do this, we make use of photos taken before the teeth were lost, as well as using the facial features as a guide. You as the patient have to decide whether you want your dentures to look much like your natural teeth did, including any gaps and uneven areas, or whether you want to make your new teeth more regular and uniform than the originals.
In addition to the size, spacing and locations of the teeth, decisions must be made regarding the colors and textures of the part of the denture that fits over and looks like gum tissue. Photos can help with this aspect as well. Ridges can be added to the section of the denture behind the upper front teeth to aid in natural speaking and chewing.
The upper and lower dentures must be designed so that in the process of biting they stabilize each other. This is called “balancing the bite.” This is necessary for normal function and speech.
All this careful planning and design are only the beginning. The dentures will be created in a wax form, tested and modified. They are then completed in a dental laboratory, where the new teeth and gums are created out of a special plastic called methyl methacrylate. With careful planning, skill and artistry they are made to look like natural teeth and gums.
At this point the role of the denture wearer becomes vitally important. He or she must relearn how to bite, chew, and speak while wearing the dentures. As the dentures press down on bone and gum tissues, over time some bone will be lost. This will require coming in for frequent checkups and modifications to make sure the dentures continue to fit well and comfortably.
