Device for manual unstressed osteotome mucotome for taking three-layer autograft from maxillary tubercle

INTRODUCTION. Recently, the direction of dentition defects restoration on artificial supports with immediate dentoalveolar reconstruction of the alveolar process which is widely used for the bone crest and soft tissues loss develops rapidly. The main factors in the formation of destructive changes in the alveolar process are chronic foci of infection in the periapical region, localized and generalized pathologies of periodontal tissues, fractures of the bones of the facial skeleton and teeth, as well as non-carious lesions of the roots of the teeth (internal and external resorption). In this regard, when performing dental implantation, it is necessary to pay attention to the implementation of additional interventions restoring the anatomical shape of the alveolar process using various tools, materials and methods. Taking into account the above, a manual unstressed mucotome-osteotome device was developed for taking a three-layer autograft from the tubercle of the upper jaw, and the results of its practical use are presented in this research.

AIM. Purpose of the research is to improve the efficiency of surgical and orthopedic stages of dental defect repair in dental implantation with dentoalveolar reconstruction by developing a special device.

MATERIALS AND METHODS. The paper presents the results of our practical application of the manual unstressed mucotome-osteotome for taking a triplraft from the retromolar region of the upper jaw (tubercle) (patent application No. 2025131706 dated 14.11.2025). At the same time, a dynamic analysis of the effectiveness of our developed device for three years was carried out in 112 clinical cases in the age group from 21 to 69 years old. Statistical evaluation of the obtained results was carried out in the MS Office Excel program using standard methods.

RESULTS. The combination of the main features of the developed device and its use contribute to improving the quality of graft preparation by extracting a single three-layer graft consisting of mucosal connective tissue with periosteum, cortical and spongy bone tissue from the tubercle of the upper jaw, which determine the clinical effectiveness of its use in osteoplastic operations and simultaneous dental implantation.

CONCLUSIONS. The obtained clinical results of practical application of the developed manual unstressed mucotome-osteotome for sampling a three-layer autograft from the maxillary tubercle characterise its effectiveness, safety and ease of use of the given medical device.
