[Theoretical and clinical prerequisites for the use of fragments of molar roots as abutment for dentures].
Experimental and clinical studies confirmed the possibility of using fragments of a multi-root tooth as abutment tooth for a bridge denture. When planning orthodontic treatment, choosing the abutment teeth, designing the denture, and treating the patient the orthodontist should be able to use the information on the maximum allowable loading of the fragments of resected teeth. A positive factor in utilization of the remaining tooth fragment is the ratio of clinical crown and root length, which should be inversely proportional. The study showed that retention of the morphofunctional integrity of dentition is possible when using dentures ensuring the optimum regulation stress (no higher than physiologically tolerable) in abutment tissues. Analysis of remote clinical and X-ray data showed normalization of the periodontal function of tooth fragments after tooth-sparing operations in cases when the patients were fitted with prostheses with consideration for theoretically valid methods for estimation of reserve force.
