[Hemisection of the mandibular molars and their use for orthodontic purposes].

The results of a combined treatment of 41 patients with chronic periodontitis of lower molars are described. The four-stage technique of hemisection is presented in detail: (1), endodontic treatment of a preserved root; (2), crown reconstruction beneath the root in the form of the premolar; (3), separation of the afflicted root from intact ones using an improved set of minute instruments; (4), diseased root extraction. The recommendations are given to improve the orthopedic treatment.
