gingivalis induced periodontal bone resorption(PBR) in rat.

Three-dimensional finite element analysis of stress distribution about abutments periodontal membranes of separated removable partial denture and traditional removable partial denture;

The factors of root resorption during orthodontic treatment;

Influence on root resorption by distalizing molars with face bow;

Root resorption observation of molars distalized by face bow using dental positioning films;

Multiple idiopathic cervical root resorption(MICRR)is a clinical term used to describe a relatively uncommon,insidious and often aggressive form of cervical external tooth resorption.

Conclusion When the distant-abutment periodontal tissues were absorbed by 1/3,the pressure on the abutments periodontal tissues and the alveolar bone under the denture was obviously enlarged,and increasing the abutment number couldn\'t effectively decrease the pressure of supporting tissues.
