The fabrication of a set of complete dentures is a challenge for any dentist/denturist. There are many axioms in the production of dentures that must be understood; ignorance of one axiom can lead to failure of the denture. In the vast majority of cases, complete dentures should be comfortable soon after insertion, although almost always at least two adjustment visits are necessary to remove the cause of sore spots. One of the most critical aspects of dentures is that the impression of the denture must be perfectly made and used with perfect technique to make an accurate model of the patient's edentulous (toothless) gums. The dentist or denturist must use a process called border molding to ensure that the denture flanges are properly extended. An array of problems may occur if the final impression of the denture is not made properly. It takes considerable patience and experience for a dentist to know how to make a denture, and for this reason it may be in the patient's best interest to seek a specialist, either a prosthodontist or denturist, to make the denture. A denturist is a trained and licensed professional who sees patients in need of dentures, partials, relines or repairs. A denturist not only takes the impression, but makes the entire denture in his or her own laboratory. The denturist then schedules a date for the delivery of the finished dentures to the patient. A general dentist may do a good job making dentures, but only if he or she is meticulous and experienced. Many dentists no longer make dentures themselves. but instead take an impression of the patients' mouth and then either send the impressions to a dental laboratory, which could be anywhere in the world, or send the patient to a denturist. Once the laboratory receives dental impressions of the patient's mouth, the laboratory creates plaster molds from them. The laboratory uses the molds to create the wax rims used to register the patient's bite. These wax rims are returned to the dentist, who uses them to register the patient's bite. The dentist may assist the patient in choosing the correct size of teeth for the dentures, or simply make the selection himself. Once bite registration is completed and the teeth are selected for the dentures, the wax rim is usually returned to the dental laboratory in order to have the denture teeth set into the wax. Once the teeth are set into the wax rim, the result is a prefinished denture that looks almost like the finished product. This prefinished denture is usually returned to the dentist's office and the patient usually has a chance to approve the setup (for immediate or standard dentures) or to try the denture before it is finished. After approval by the patient, the dentist returns the pre-denture to the laboratory for final processing. The finished denture is then returned to the dentist's office for delivery to the patient.
Making quality dentures is a blend of science and art. First, an accurate impression (mold) is made of the alveolar ridges on the top and bottom of your mouth. The base of the denture is made from this mold in a dental laboratory. Working together, the dentist and lab technician choose from among many different sizes and shapes of prosthetic teeth to re-create a natural-looking smile. When everyone is satisfied with the result, the temporary dentures are made in permanent form.
In addition to the complications that are specific to the implant, abutments, and dentures, there are various oral health problems that can occur in patients with dentures. Patients should keep their teeth and gums clean, and visit the dentist every six months so problems, if they exist, can be identified and treated. The types of oral health problems that commonly affect patients with dentures include:
Over a period of time, your denture will need to be relined, remade, or rebased due to normal wear. Rebasing means making a new base while keeping the existing denture teeth. Also, as you age, your mouth naturally changes. These changes cause your dentures to loosen, making chewing difficult and irritating your gums. At a minimum, you should see your dentist annually for a checkup.
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.
Partial dentures, or partials, are dentures that replace only a few missing teeth in the patient’s mouth. Partials rest on a metal framework that will be latched onto the patient’s natural teeth for support. If the patient’s existing teeth are insufficient, dental crowns are usually used to augment the natural teeth and serve as more stable anchors for the partial dentures.
MCCALLA, ALABAMA -- 5/8/18 I had all my remaining top teeth removed & an immediate denture (ID) put in. First, I was the last surgery of the day. The dentist let all his experienced staff leave & had the receptionist assist him! He had to tell her every little thing to do. She couldn't even work the suction instrument correctly & she finally just quit suctioning my mouth!
Implant technology can vastly improve the patient's denture-wearing experience by increasing stability and preventing bone from wearing away. Implants can also aid retention. Instead of merely placing the implants to serve as blocking mechanism against the denture's pushing on the alveolar bone, small retentive appliances can be attached to the implants that can then snap into a modified denture base to allow for tremendously increased retention. Available options include a metal "Hader bar" or precision balls attachments.
When you lose a tooth, the nearby teeth may tilt or drift into the empty space. The teeth in the other jaw may also shift up or down toward the space. This can affect your bite and place more stress on your teeth and jaws. You may find it harder to clean teeth that have shifted, which can lead to tooth decay and gum disease. That is why it is important to replace missing teeth.
Having a complete set of bright and well-aligned teeth can give you a beautiful smile. When a person loses his or her teeth to disease, injury, accidents or age, the gaps in the smile are usually enough reasons to warrant a dental solution. Of course, the reasons for treating missing teeth goes beyond aesthetic reasons and extends into the realms of health, such as personal well-being and simply feeling good about oneself.
The gums, tongue and palate should be brushed with a soft bristle brush every evening when the dentures are removed, and each day before you insert them to stimulate the gums and remove plaque accumulation. When removing dentures at night, brush them carefully to remove any loose debris and plaque then soak them in a cleansing solution. Your dentist will be able to recommend one. Some people keep theirs in an ultrasonic cleaner, but keep in mind that an ultrasonic cleaner doesn’t replace brushing. When cleaning your dentures, place a towel beneath them or clean them over a sink filled with water to avoid breakage.
Dentures are removable appliances that can replace missing teeth and help restore your smile. If you’ve lost all of your natural teeth, whether from gum disease, tooth decay or injury, replacing missing teeth will benefit your appearance and your health. That’s because dentures make it easier to eat and speak better than you could without teeth—things that people often take for granted.
