Resorption is exacerbated by pressure on the bone; thus, long-term complete denture wearers will experience more drastic reductions to their ridges than non-denture wearers. Those individuals who do wear dentures can decrease the amount of bone loss by retaining some tooth roots in the form of overdenture abutments or have implants placed. Note ...
Periodontal disease; Other names: Gum disease, pyorrhea, periodontitis: Radiograph showing bone loss between the two roots of a tooth (black region). The spongy bone has receded due to infection under tooth, reducing the bony support for the tooth.
The advanced lesion is no longer localized to the area around the gingival sulcus but spreads apically as well as laterally around a tooth and perhaps even deep into the gum tissue papilla. There is a dense infiltrate of plasma cells, other lymphocytes and macrophages. The clusters of perivascular plasma cells still appears from the established ...
Healthy gums fill and fit each space between the teeth, unlike the swollen gum papilla seen in gingivitis or the empty interdental embrasure seen in periodontal disease. Healthy gums hold tight to each tooth in that the gum surface narrows to "knife-edge" thin at the free gingival margin. On the other hand, inflamed gums have a "puffy" or ...
Gingival recession, also known as gum recession and receding gums, is the exposure in the roots of the teeth caused by a loss of gum tissue and/or retraction of the gingival margin from the crown of the teeth. [1] Gum recession is a common problem in adults over the age of 40, but it may also occur starting in adolescence, or around the age of 10.
In theory, gingival fibers are the protectors against periodontitis, as once they are breached, they cannot be regenerated.When destroyed, the gingival sulcus (labelled G in the diagram) increases in depth apically, allowing more debris and bacteria to remain in intimate contact with the delicate sulcular and junctional epithelia for longer times.
The bone destruction patterns that occur as a result of periodontal disease generally take on characteristic forms. This X-ray film displays a horizontal defect . This X-ray film displays two lone-standing mandibular teeth, #21 and #22: the lower left first premolar and canine, exhibiting severe bone loss of 30-50%.
The findings support the concept that a healthy and stable occlusion can exist despite missing teeth as long as an acceptable number of teeth are in occlusion. However, this management technique may not be suitable for those with gum disease, parafunctioning activity (tooth grinding or clenching) or malocclusion. [74]
