Prosthodontics Case Studies

ABSTRACT

It is rightly said preservation of what remains is more important, with this in consideration preventive prosthodontics can be appropriately applied highlighting the importance of delaying or eliminating future prosthodontic treatment. In this case study mandibular tooth supported BPS (bio-functional prosthetic system) overdenture and maxillary flexible partial denture was fabricated for the patient. This gives the patient a denture that has more support and retentive principles incorporated, resulting in improved retention. Decrease in rate of resorption of bone hence preservation of alveolar ridge. Overdenture patient possessed preserved sensory function, i.e., discriminating between occlusal forces closer to natural teeth. These

The overdenture is defined as a removable partial denture or complete denture that covers and rests on one or more remaining natural teeth, the roots of natural teeth and / or dental implants; a prosthesis that covers and is partially supported by natural teeth, natural tooth roots and / or dental implants–GPT 7.

The idea of leaving roots of natural teeth to support an overdenture is far from new; even in 1856, ledger had described a prosthesis resembling overdenture. (book) or

The existence of the periodontal membrane under the overdenture gives the patient a sense of discrimination not possible with conventional dentures. Natural tooth stops of an overdenture provide for a static, stable base unparallel by any conventional denture. The overdenture literally does not move. Retention is usually sufficient merely by overlaying the teeth. It is true that there is a large initial cost, mainly due to periodontal and endodontic treatment and occasionally due to the fabrication of a cast coping or cast retainer device. However, when weighing total service involved, the case of maintenance in years to come, the low percentage of remakes, and the alternative treatment of extensive fixed and removable partial prostheses, the cost of an overdenture compares very favorably with different treatment. Patients are most receptive to and appreciative of this treatment because they experience a striking improvement in function and esthetics while still maintaining some of their own teeth. The overdenture concept is designed so that if for some reason overlaid teeth must be extracted, the overdenture can readily be converted to accept the alteration. Even if all the teeth must be lost, the overdenture, because of its basic complete denture design, can be easily
