The aim of this study was biomechanical rationale for splinting mobile teeth with periodontitis according to the height and slope of teeth crowns, their degree of mobility, and type of occlusion. The research studied the effect of axial vertical and horizontal loads on the functioning of the proposed method of splinting. Set clear indications and contraindications for the use of the method of splinting. Biomechanically proven unreasonableness includes teeth with III degree of mobility in the splinted construction. Clinical variant of splinting is only possible at the height of the anatomical crowns of the teeth of at least 7 mm, otherwise the preferred laboratory methods for the manufacture of tires.

Clinical case of prosthetic rehabilitation of patient (female) with generalized parodontitis complicated by defects and deformations of dentitions was offered. Using 3D-technologies position of teeth was corrected with the help of a series of temporary transparent splints-modifiers with subsequent guy splintage and esthetic 3D-planning of front teeth forms. Teeth forms correction was made by composite using preliminary prepared templet.

The experience of use Michigan splint for temporary splinting of the maxillary tooth at realization of flap surgery at 23 patients. Stages of clinical and laboratory procedures making the splint are described and analysed. Is appeared, that the reduction of mobility of teeth in the period following surgical intervention occurs on the average within 0.5-1 month faster, than with the patients after similar interventions, but without splinting. At the same time it is proved obvious, that the usage Michigan splint promotes normalization of functioning of muscles activity masticatory system and TMJ and helps in revealing of occlusal interferences.

One of the elements of gyuing dentures suggested by the author is described in detail. It serves for redistribution of masticatory loading between natural teeth and can be used alone (for tooth splinting) and in combination with other elements of the proposed denture system (for orthodontic treatment of partial defects of dentition). The schemes of splinting and their biomechanics are described in detail. High reliability of the proposed design is emphasized.

A simple, reliable, and easy-to-make splint is proposed for immobilization of the dislocated upper and lower incisors. The splint does not prevent correct occlusion, is hygienic and atraumatic. The process of immobilization of the dislocated tooth is accelerated if half-products are available. The splint consists of processes for fixation and the part fixing the tooth, its vestibular part involves the palatal surface of the tooth and is finished with an occlusion pad. The splint is fixed with bronze-aluminium wire to 2-3 healthy teeth on both sides of the dislocated tooth.

The authors analyze various orthodontic constructions used in multiple-modality treatment of periodontal diseases. Special attention is paid to combinations of direct fitting with prostheses and use of the novel osteoinductive and immunomodulating agents. Nineteen patients with periodontal diseases were treated. Removable splints, prosthetic splints, and other devices were employed. Special emphasis is made on the use of biositall M-31-a composition on the basis of hydroxyapatite and Algigel. All these materials were found to be effective at the stage of surgical treatment of periodontal diseases, particularly so in combination with immediate prostheses and sodium alginate-based therapeutic films.

The authors compare the periodontal status in 94 patients with moderate periodontitis over the course of treatment making use of various splint designs and without splints. The status of the periodontium was assessed basing on the time course of indexes. Administration of various multiple-modality treatment schemes resulted in improvement of the periodontal clinical status in all the patients, though the efficacy of the therapeutic measures was different. The improvement in respect of all the examined parameters was the most manifest only in the group of patients treated with fixed splints with parapulpal fixation or with those pickling-based.

Immediate and late results of periodontitis treatment with the use of various types of joining in 74 patients are analyzed. Traditional casts were employed in 34 cases; in 40 patients fragmentary nonremovable casts with parapulpar fixation were used, as were adhesive one-piece, equatory, and intradental casts. The initial condition of the periodontium was similar in all the patients. Periodontal status was compared over the course of treatment with the use of different casts. Mathematical characteristics were used for analysis: periodontal and gingival indexes; osseous index and hygienic condition index, that were determined before, 30 days, and 12 months after treatment. Only two of the four studied indexes evidenced a reliable improvement of the condition after therapy and joining by traditional techniques, but the effect proved to be unstable, and 12 months after treatment both values significantly grew again. When traditional treatment modalities are used, alleviation of the inflammation and improvement of the hygienic condition of the oral cavity depend not so much on the type of joining but mostly on the initial status of the periodontium. A more manifest and stable reduction of the inflammation and improvement of the oral cavity hygienic status were observed in the patients treated with the use of present-day more physiologic cast designs. This evidence considerable advantages of these new designs vs. the traditional ones.
