Partial Upper and Partial Dentures

Part Upper and Part Lower Dentures

Meaning:

A Denture that replaces the lost teeth of a partially toothless upper or lower jaw.

Usage:

A partial denture can be found either on the upper or lower jaw. A removable partial denture can be made for patients in need from 1 to13 missing natural teeth. Partial dentures "fill in the gaps", thus not only enhance the persons appearance but also aid in function such as improved eating and speaking. The use of a partial denture spreads the forces placed upon natural teeth during mastication. It also stops natural teeth from "drifting" as the back teeth have a tendency to drift forward and the upper back teeth drift downwards or upwards to find an opposing tooth.

Materials used:

Partial dentures at our denture clinics can be manufactured using chrome cobalt (a type of metal). Metal dentures are smaller thinner, stronger and last longer due to NO wear and tear. The clasps (clips) made out of metal fit around the natural teeth perfectly and often tend to support them. This is due to a casting machine adapting the clasps directly onto your natural teeth during the process. Alternatively plastic material can be used including "hi impact" acrylics. The chemical structure of such acrylics makes the denture material stronger, more resilient to wear and breakage, but it does not compare to the strength and size of a chrome cobalt denture material. The clasps of a plastic denture are hand wrought and cannot compete with the accuracy when using a centrifugal casting machine for a chrome cobalt denture. Then there are flexible thermoplastic dentures. These type of appliances are undetectable, durable and resistant to breakage. Our clinics more often provide this type of denture to any other.

Clinical Procedures:

Initial assessment: Prior to commencement the Dental Prosthetist will take a health and dental history and obtain a reason for presenting. This includes answering a few questions concerning the patient's general and dental health. The old dentures are also examined. This process allows the practitioner to obtain patients expectations, a treatment plan and a prognosis. Often a quotation of fees is given, alternatives and the method of payment discussed. If agreement is reached the next step for the denture treatment is arranged. Commencement of the Partial denture construction follows immediately after the assessment or an alternative appointment time may become necessary.
(Time: approx.30-40mins)

Primary impressions: Initial impressions (imprint) of the upper and lower jaw are made. This involves placing special material (non drip) into an appropriately sized impression tray and placing it into the mouth. Once to the upper jaw and once to the lower jaw. The reason for this procedure is to produce an initial model of the mouth in order to produce specially fitting trays, referred to as "special trays". These trays will be produced by our dental technician in the laboratory.
(Time: approx.20mins)

Secondary impressions: Another lot of impressions is taken in the specially prepared "special trays" using different (usually non drip) material. The reason for this procedure is to obtain a more accurate representation of the mouth.
(Time: approx.20mins)

Bite Registration: A "bite block" (wax rim resembling a denture shape) is placed into the patients mouth and skillfully trimmed and manipulated to obtain the correct contour and length. Special measurements such as: centre, lip length and jaw relation ship will be taken. This procedure will be checked on the next visit for its accuracy. At times the skill of the operator is not enough to get this procedure correct on the first time without the help of a relaxed and responsive patient. Also during this visit, teeth will be selected. This is discussed closely with the patient. The complexion, colour of hair, eyes and shape of the face as well as remaining natural teeth and the teeth on the old dentures are all taken into consideration. Once selected the next step will be prepared in the laboratory.
(Time: approx.30mins)

Try in: The teeth selected during the previous visit are now presented to the patient set into the bite rim. Like a denture made out of wax with the teeth on set into wax will be placed into the patients mouth. Initially the practitioner will check all necessary dimensions as well as the previously taken bite registration. If all looks well then the patient is reminded of the purpose of this visit and handed or pointed to a mirror where the patient can check the appearance. It is a good idea to bring a trusted friend or a member of the family to give a second opinion. This visit is very important as generally the appearance cannot be changed when the denture is finished.
(Time: approx.20mins)

New denture insert: The denture is now ready and the wax has been replaced with highly polished and characterised acrylic that resembles human gingival tissue (gums). All dimensions and the fit is checked once again and the patient is shown the finished dentures in a mirror. Instructions concerning the care of gums teeth and dentures are given at length and the patient expectations are discussed. Patient is instructed to persevere with the new denture but not over persevere and encouraged to return for a check visit in a week or earlier if necessary.

Check visit: During this visit the patient tells the Dental Prosthetist his/her problems (if any) with the new denture . The mouth and denture are then thoroughly checked and if necessary adjustment to the denture is made. Once again the patient is reminded of returning for further adjustments at later stage if found necessary.

Note: There are circumstance where this process described above may not be used. The Dental Prosthetist may decide on a totally different technique he considers more appropriate for a particular patient.
