Cone Beam Computed Tomography (CBCT) is variation on conventional Computed Tomography (CT). “Cone beam” refers to the cone shaped beam which usually scans patients in vertical axis to the region of interest (ROI), obtaining nearly 600 distinct images, creating 3D images of object and converting the data in the readable format such as DICOM file format. CBCT is predominantly used in Dental implants, and other areas such as Orthopedics, Interventional radiology, oral surgery, ENT and in certain types of X-ray imaging process. During the processing of radiographic imaging system, various parameters are needed to be considered which are specific to the CBCT imaging includes, X-ray generation, X-ray attenuation by an object, detection of signal, image processing and image display.
Furthermore manufactures of CBCT imaging equipment, are working on various aspects of improving the imaging application more cost-effective, and efficient, by making scanners even smaller, and ability to scan patients in upright positions by using flat panel detectors. CBCT applications are helpful in multiple aspects of dental disciplines. These applications include dental abnormality, vertical root fractures, jaw tumors, prosthodontic evaluations and implant dental evaluations.
Players in the cone beam computed tomography market focus on fueling the growth by boosting these 2 factors mainly, first is launch and availability of improved, rapid and cost-effective computer technology and the second is development of improved software in the CBCT imaging having broad diagnostic capacity. For instance, in March 2019, Planmeca Oy, introduced an advanced Planmeca Viso G5 in the Planmeca Viso family, which offers high CBCT image quality. Similarly, in January 2017, PreXion, Inc., launched advanced PreXion3D Excelsior CBCT in the dental industry which can deliver 30% lower radiation exposure without hampering the image quality. Also, in September 2017, KaVo Kerr introduced KaVo OP 3D, an advanced 3D and cephalometric imaging system developed for meeting the imaging needs of general dental practitioners, craniofacial surgeons and other specialists.
Growth of the cone beam computed tomography market is primarily driven by rise in the dental disorders. Conversely high cost of advanced imaging technology and stringent regulations regarding X-ray exposure within different countries are some constraining factors limiting the growth. The cost of cone beam computed tomography device is significantly high, typically around US$ 100,000. However cone beam imaging in U.S. range from US$150 to US$ 700 per scan.
While in terms of radiations dose, National Center for Biotechnology Information (NCBI), in 2015, studied various article to analyses the dose measurement and effective dose estimation for dental CBCT device. The resulted data reveals the adult effective doses are ranges from 5 to 652 millisievert for small fields of view (FOVs), 9 to 560 millisievert for medium FOVs and 46 to 1073 millisievert for large FOVs. Additionally in March 2012, various evidence based guidelines on CBCT dentistry were laid by the European Commission. European Commission’s “Radiation Protection” series has concluded that radiation dose from dental CBCT is considerably higher over dental radiography. According to the European guidelines, the effective radiation range for dento-alveolar and craniofacial dental CBCT ranges from 11-674 millisievert, 30-1073 millisievert, respectively.
Recent advancement in Cone beam computed tomography:
Recently Prexion Inc. provider of CBCT equipment launched new CBCT scanner possessing smallest focal point (0.3 mm) and delivering 30% lower radiation emission without compromising on the image quality. Carestream health Inc., a provider of dental imaging systems, acquired 42 new patents in the field of Cone beam CT imaging and other device areas from US Patent and Trademark office in 2016. Additionally, it also acquired 52 patents in the European and Asian regions in the same year. Patents includes the new images capture technology which enables easy way of imaging any deformities or functional impairments in orthopedic extremities and spine by using CBCT.
Rising numbers of the dental implants fueling the growth of Cone beam computed tomography market:
According to the American Academy of Implant dentistry, the prosthetic and dental implant market in the U.S. is projected to reach $6.4 billion by 2018. More than 5 million dental implants procedure are done in the U.S. each year. Dental implants are mostly accepted during permanent tooth replacement. CBCT helps to identify the characterization of anatomy, finding out certain abnormalities during dental implants and possibility rate to adoption new dental implants by imaging. CBCT thus helps to make procedure more interactive and easy to adopt by dental professionals. Accordingly due to the high cost, high risk of radiation exposure and difficulty adapting accessibility with conventional computed tomography, CBCT scores more over conventional tomography.
Developed regions are major growth engines of cone beam computed tomography market:
Developed countries such as the U.S., UK, Germany, and Italy accounts for major share in these market owing to the promotion strategies executed by the market players, high numbers of prevalence of dental disease and conditions, introduction of advanced technology adaptation in the cone beam computed tomography market, adoption of smaller design structure to be best suiting the need of the healthcare professionals are major factors to acquire higher market share in the developed economies. For instance, in August 2017, KaVo Kerr announced the expansion of its DEXIS and i-CAT imaging solutions to Patterson Dental, which promoted KaVo Kerr products in the U.S. and enhanced its offering of advanced technologies across the U.S.
Asia pacific regions exhibited the significant growth in near future due to the rising numbers of dental and orthopedic population, higher acceptance rate for newly advanced technologies in CBCT system.
Key players operating in the cone beam computed tomography market includes Carestream Health Inc., Dentsply Sirona, Genoray, Instrumentarium Dental Inc., Planmeca Oy, Ray Ltd., Gendex Dental systems, Brainlab AG, NewTom, Danaher Corporation, Vatech Ltd., J. Morita Corporation, Asahi Roentgen Ltd., and PreXion Inc.
