Status of the maxillary bone after Coldwell - Luc operation

It is known that a trepanation bone defect in the front wall of the sinus remains after Coldwell Luc surgical operation in the maxillary sinus. Mild tissues of cheek and scarry tissue in the presence of defect grow into the cavity of the sinus that brings about the relapse of inflammation and development of pathological syndrome. Methods of filling a defect by transplants and implants are used for liquidation of trepanation defect. Under insufficiently hard fixation of implant its rejection takes place due to deformation under variable chewing loads. Therefore it is necessary to conduct the biomechanical study of the maxillary bone and mathematical substantiation of choice of sizes of trepanation defect and need of its closing. For this purpose Coldwell Luc operation is considered and analysed its consequence for the maxillary bone both from medical and from biomechanical viewpoint with the help of solution of boundary-value problem of theory of elasticity.
