Cone-beam computed tomography in dental practice: Literature review and own observations

Abstract

Abstract A cone-beam computed tomography (CBCT) is a diagnostic method that provides radiographic visualization with an accurate three-dimensional (3D) image of hard tissue structures. CBCT is a modern diagnostic method in dentistry that promises many advantages in the near future, and the possibilities of its use are almost unlimited, provided that it is prescribed reasonably and appropriately. The purpose of this article is the review the possibilities of using cone-beam computerized tomography in dental practice, taking into account the advantages and disadvantages, with illustration of specific clinical cases. The main cases of CBCT usage in dentistry are endodontics, implant planning, orthodontics and orthopedics, diseases of the temporomandibular joint. The article is justified on the basis of literary sources and on the basis of own observations of the use of KPKT in various fields of dentistry, the most significant examples of the use of this diagnostic method, limitations in certain cases and prospects for future use are given. CBCT method is of primary importance for diagnosis, treatment planning and direct selection of the root canal treatment method. It also has undeniable advantages in diagnosing complications in endodontics. CBCT should not be the «gold standard» in orthodontic practice, but should be used only in cases of difficult diagnosis or treatment optimization. CBCT may be justified for preoperative diagnosis, planning, and postoperative rehabilitation, on condition of optimization hardwaredependent, specific, and nonspecific factors that may affect the quality of diagnosis. CBCT may be justified for preoperative diagnosis, planning, and postoperative rehabilitation, on condition of optimization hardware-dependent, specific, and nonspecific factors that may affect the quality of diagnosis. It is also important to use different modes, viewing images in different planes in each case, but with the obligatory justification of their expediency. This brief review summarizes the knowledge of CBCT use in various fields of dentistry and will be useful for practicing dentists, as it is accompanied by illustrations of specific cases from practice.
