Abstract
Osseodensification is an innovative surgical instrumentation technique based on additive (non-cutting) drilling using special burs. The osseodensification burs should operate in a clockwise direction to drill holes and in a counterclockwise direction to compact the osteotomy walls. For these purposes, the burs have special design features, like conical contour shape, increased number of helical flutes and negative rake angle on their peripheral part. However, although other parameters and features of the burs define their overall performance, they are not described sufficiently, and their influence on the surgical quality is almost unknown both for clinicians and tool manufacturers. The purpose of the present research is to identify the key design features of burs for osseodensification and their functional relationship with the qualitative indices of the procedure basing on analytical review of research papers and patent documents. It will help to further improve the design of osseodensification burs and thereby enhance the surgical quality and, ultimately, patient satisfaction. Results: The most important design features and parameters of osseodensification burs are identified. Thereon, the structural model of osseodensification bur is first represented as a hypergraph. Basing on the analysis of previous researches, functional relationships between design parameters of osseodensification burs, osseodensification procedure conditions and procedure performance data were established and for the first time described in the comprehensive form of a hypergraph. Conclusion: This study provides formal models that form the basis of database structure and its control interface, which will be used in the later developed computer-aided design module to create advanced types of burs under consideration. These models will also help to make good experimental designs used in studies aimed at improving the efficiency of osseodensification procedure.
