Do You need a new set of complete dentures?



Prosthodontics is the branch of dentistry pertaining to the restoration and maintenance of oral function, comfort, appearance and health, by the restoration of natural teeth or the replacement of missing teeth with artificial substitutes. 

Any artificial replacement of a missing body part, including teeth, is known as a prosthesis or prosthetic. 

Complete Denture

A complete denture or a full denture is a removable prosthetic that replaces all teeth in the mouth. Facial muscles aid in the control and function of the denture. No matter how much care is take in the fabrication of a complete denture, it will never allow the same function as the natural dentition. Often success or failure of a denture is dependant on the tolerance the patient has for the difference. A complete denture is held in by the alveolar bone and oral mucosa, surrounding tissues and palatal structures. 

Careful diagnosis and treatment planning are just as important in the fabrication of complete dentures as they are in any other dental treatment. The treatment plan must consider the need for surgery and the specific design of the appliance. Every aspect of the patient health must be considered; age, habits, jaw relationship, saliva flow, occlusion, dietary habits, aesthetic expectations, alternatives to complete denture, oral hygiene,and tori, are all useful in determining the appropriate plan for the patient. 

Components of a Complete Denture
  1. Base: fits over the alveolar ridge and gingival tissue. It is usually made of tissue coloured acrylic. If additional strength is needed a wire mesh can be embedded in the acrylic.
  2. Flange: extends into the vestibule are facially as well as lingually or palatially.
  3. Post Dam: often described as the posterior palatal seal on a upper jaw complete denture. It extends across the entire palate behind the maxillary tuberosity.
  4. Denture Teeth: the teeth which are used in a complete denture can be made out of acrylic or porcelain. They are set to an acrylic base. A full denture will have 14 teeth in an arch as the wisdom teeth are excluded (there's usually no room for them anyways)
