The possible advantage of improved appearance and function offered by partial dentures should be balanced against their long-term potential to cause harm to the remaining teeth and supporting soft tissues suggest by dentists in China dental lab. In broad terms this harm can be described as a risk of local damage to the remaining teeth resulting from an increased incidence of caries and periodontal disease and the continued resorption of those parts of the alveolar process supporting the partial denture.

In next serval texts I will introduce some long-term effects of using partial dentures patients. Main as following aspects:
1. Caries and periodontal disease.
2. Plaque and partial dentures.
3. Changes to the alveolar process.

Changes to the alveolar process
Resorption of the supporting alveolar process is a frequent clinical finding. Common consequences are reduced retention, instability, loss of occlusal contacts and fracture of denture components. Further, Trauma from the resulting ill-fitting dentures may well cause inflammation of the denture bearing mucosa. Such trauma and an overgrowth of the fugus Candida albicans are thought to be the most common causes of denture-induced stomatitis not infrequently seen under ill-fitting upper dentures.

The question as to whether there is a cause-effect relationship between this resorptive process and denture use has not been clearly answered. Although several studies strongly suggest this relationship, the small study populations and the large individual variations seen have case doubt on the validity of the results. There is no evidence for the concept of disuse atrophy in non-denture wearers.
