Before a denture can be created and placed, a patient needs to have an initial consultation and evaluation by a general dentist or a prosthodontist. This will include a comprehensive dental examination and a medical and dental history. X-rays and impressions of the teeth may be taken. This information will allow the dentist and patient to discuss options and preferences.
Teeth usually must be extracted or otherwise prepared for the denture. Dentists typically try to save as many natural teeth as possible because no form of artificial teeth performs as well as natural teeth. Retaining some natural teeth also enables the use of overdentures or partial dentures, which tend to be more stable and secure than conventional dentures.
The time it takes to place a denture and the process used depends on the type of denture to be placed. For conventional dentures, impressions are made after the teeth have been extracted so that the gums have time to heal before the denture is placed. The impressions are sent to a dental laboratory, where the denture is made.
The denture is typically sent back incomplete. In another appointment, the artificial teeth are secured on the denture base with wax for a trial fitting. This helps ensure that the color, shape and fit of the denture works well for both the patient and the dentist. Some patients may have multiple trial fittings, or “try-ins,” before the best fit, occlusion (bite) and match is achieved. After the fit, occlusion and match are adequate, the teeth can be permanently secured onto the base.
If an immediate denture is planned, impressions are made before the teeth are extracted so that the denture can be placed during the same appointment as the extraction. For a partial denture, the adjoining abutment teeth usually need to be prepared, such as with an artificial crown.
If an overdenture is planned, the teeth that will support the denture are reshaped by a dentist to fit the denture. These teeth usually need a root canal treatment prior to the reshaping. The reshap ed teeth are covered with copings (metal castings) to improve their fit with the dentures. If natural teeth are not available, implants may be used. An impression is made after the natural teeth have been shaped or the implants are in place. Implants usually require several visits that take place over a period of months. |
