Description of Device: ORTHOPANTOMOGRAPH™ OP 3D LX manufactured by PaloDEx Group Oy is a panoramic, cephalometric and cone beam CT (CBCT) x-ray device for 2D and 3D imaging of patient's cranio-maxillofacial complex. It can be used to capture 2D and 3D x-ray images from pediatric and adult patients. The Primary Predicate Device ORTHOPANTOMOGRAPH™ OP 3D has already been cleared for panoramic and cone beam CT usage (K180947). The ORTHOPANTOMOGRAPH™ OP 3D LX is an X-ray device that can be configured to take panoramic, cephalometric or 3D images of craniomaxillofacial complex, and neck areas including the ear, nose and throat (ENT). The device can be configured to take carpus images. The device is operated and used by qualified healthcare professionals. The ORTHOPANTOMOGRAPH™ OP 3D LX is intended to be used for imaging of adult and pediatric patients. The ORTHOPANTOMOGRAPH™ OP 3D LX is part of digital dental workflow providing image data for diagnosis and treatment planning for the healthcare professionals. Xray images reveal the targeted craniofacial anatomy, and condition and the position of anatomical structures inside FOV, such as teeth, mandibular joints, and oral and nasal cavities. This helps dentists to prepare for various dental procedures such as implant placement, orthodontics and dental prosthetics, providing possible early diagnosis, which enables early and less invasive treatment. Per the Guidance for Industry and FDA Staff entitled, "Bundling Multiple Devices or Multiple Indications in a Single Submission," dated June 22, 2007, PaloDEx Group Oy is bundling the ORTHOPANTOMOGRAPH™ OP 3D LX models below as they do not differ significantly in purpose, design, materials, energy source, function or any other feature related to substantial equivalence. The device description and intended use are identical for all models listed below. Also the supporting data is relevant to the ORTHOPANTOMOGRAPH™ OP 3D LX as a whole, the bundled device components and accessories are used together during therapeutic procedures, and one review group will be involved. | Model Type | Model Part Numbers | Description | |------------|----------------------------------------|-----------------------| | PCX-1 | 0.805.5753 (SAP) / 901265-PTU (Oracle) | OP 3D LX (PAN 3D) | | PCX-1 | 0.805.5754 (SAP) / 901266-PTU (Oracle) | OP 3D LX (PAN CEPH 3D | Table 5.1: ORTHOPANTOMOGRAPH™ OP 3D LX models ## Principle of Operation / Mechanism of Action: Panoramic imaging is used for acquiring 2D images. In the panoramic mode the rotating unit rotates around patient head and scans the patient with a narrow x-rav beam. Generation of exposure is turned off and turned on during the exposure to produce partial panoramic, bitewing (BW) and TMJ (Temporo Mandibular Joint) images. Cephalometric imaging is performed by utilizing a second x-ray source. System is using same sensor for all imaging modalities. Both the x-ray source and the rotating unit make a scanning movement to produce either lateral cephalometric or PA image of the patient's head by using a narrow x-ray beam. Patient head is positioned in the ceph {5}------------------------------------------------ head support. For carpus imaging there is a dedicated carpus holder to be attached to the ceph head support for supporting the object during exposure. In 3D CBCT mode the rotating unit rotates around patient's head and scans the patient with a rectangular beam, where the beam size is adjusted depending on the selected FOV (Field-of-View) size. Several 2D projection images are recorded during this rotational movement. These 2D images are saved, and based on the data, the 3D data is generated by reconstruction. Once images are reconstructed, they can be viewed in an image viewing software (dental application). The image viewing software is not part of this proposed device. ## Accessories: The Accessories for the ORTHOPANTOMOGRAPH™ OP 3D LX are listed in Table 5.1A below. All Accessories are the same/identical to the cleared Primary Predicate Device ORTHOPANTOMOGRAPH OP 3D (K180947). | Device /<br>Accessory | Description | Manufacturer | |-----------------------|-------------------------------------------------------------------------------------------------------------------------------------------|------------------| | Disposable<br>covers | Intended to serve as a disposable barrier for dental<br>instruments to reduce the risk of cross contamination<br>between dental patients. | Palodex Group Oy | | Chin rest | Used with bite block or lip support in standard and<br>pediatric imaging to provide patient support | Palodex Group Oy | | Bite block | Used with chin rest in standard and pediatric imaging for<br>dentate patients to provide patient support | Palodex Group Oy | | Lip support | Used with chin rest in standard and pediatric imaging for<br>edentulous patients and for TMJ imaging to provide<br>patient support | Palodex Group Oy | | Head support | Used to provide patient support | Palodex Group Oy | | Carpus holder | Used in carpus imaging to provide patient support | Palodex Group Oy | ## Table 5.1A: Accessories #### ട.

Substantial Equivalence: #### Details of the similarities between subject and predicate devices: A The similarities between Subject Device, ORTHOPANTOMOGRAPH™ OP 3D LX, and the Primary Predicate Device, ORTHOPANTOMOGRAPH™ OP 3D (K180947), are listed in Table 12.1 below for Technological Characteristics and Performance Testing. The proposed device ORTHOPANTOMOGRAPH™ OP 3D LX shares the similar architectural components and utilize as ORTHOPANTOMOGRAPH™ OP 3D (K180947). Both devices utilize cone beam x-ray technology to acquire volumetric data. The Conical x-ray beam rotates around the patient's head and incidents upon the receptor and the system generates volumetric data from the 2D projection images, similarly to the predicate device. Image modes, 3D resolutions, exposure times and 2D imaging programs are identical. The reconstruction of 3D images from 2D image data in the proposed device is made using the same reconstruction techniques as in the predicate device. Performance testing were conducted on ORTHOPANTOMOGRAPH™ OP 3D LX. Image quality testing was performed as part of bench testing, and the result indicate that ORTHOPANTOMOGRAPH™ OP 3D LX is substantially equivalent to the predicate devices. Biocompatibility evaluation was conducted on patient contacting parts and their material and found to be in conformance with ISO 10993-1 for both proposed and the predicate device. Software on ORTHOPANTOMOGRAPH™ OP 3D LX is designed according to the manufacturer´s software development quidelines complying with IEC 62304. Testing was performed as part of the electrical safety testing. - A Details of the differences between subject and predicate devices: There are no major differences between the subject device (ORTHOPANTOMOGRAPH™ OP 3D LX) and predicate devices (ORTHOPANTOMOGRAPH™ OP 3D (K180947) and ORTHOPANTOMOGRAPH™ OP300 (K163423)), however there are some minor differences as described below. ## Intended Use/Indications of use: "Ear, nose and throat (ENT) and airway regions, and cervical spine." is not part of the primary predicate intended use/indications of use. Secondary predicate ORTHOPANTOMOGRAPH™ OP300 (K163423) has also "neck area, ear, nose and throat (ENT) regions" included in the intended use/indications of use. Performance testing demonstrates the proposed ORTHOPANTOMOGRAPH™ OP 3D LX and both predicate devices can image the same anatomical areas, that is the dentomaxillofacial complex and neck area which include the airway regions and cervical spine. As a summary ORTHOPANTOMOGRAPH™ OP 3D LX Indications for Use statement is utilizing more descriptive wording to communicate anatomical structures inside the scanned volume. {7}------------------------------------------------ ### X-ray source: The proposed and the predicate devices utilize the same x-ray tube. The chosen technique factors are slightly different. The small difference in the device's tube current is due to the proposed device having longer SID requiring a bit larger current for imaging. ### Image Detectors: The proposed device has only one TFT (Thin Film Transistor) sensor capable of capturing all modalities (panoramic, cephalometric and CBCT image data). Using only one sensor is possible due to the bigger image detector size at the proposed device (Effective detector area 240 x168 mm) compared to the Primary Predicate (Effective detector area 125 x125 mm). TFT imaging performance is similar to CMOS sensors used with the Predicate device and equivalent clinical performance can be achieved. Measured DQE performance is substantially equivalent to the predicate device. ### 3D Field of View: The larger image detector in the proposed device enables bigger field of view options. Field of view options in the proposed device are optimized for clinical needs to achieve intended use of the device. ### Pixel size: The proposed and the primary predicate device have almost identical pixel sizes. 5 um /10 um difference in pixel sizes is not significant in clinical practice. ## System footprint: Minor difference in the adjustable height of the device does not impact the safety or effectiveness of the device. ## Materials (Patient contacting): The proposed device uses the same materials for the patient contacting parts with exception for the head support. ORTHOPANTOMOGRAPH™ OP 3D LX uses "Grilamid TR 90+ EMD- 802744 MB Black" also for the head support and "Ultradur B2550 FC+ EMD-802744 MB Black" is not used. However, these minor differences do not raise new concerns of substantial equivalence. The comparison below (Table 5-2) for the Subject Device and Predicate Devices demonstrates that the Subject device is substantially equivalent to the Primary Predicate with regards to their Indications for use, technology and performance specifications. Furthermore the subject device does not introduce a fundamentally new scientific technology, and nonclinical performance testing demonstrates that the device is substantially equivalent as the Subject device performs as well as the Primary Predicate device for its intended use. {8}------------------------------------------------ # Device Comparison Table: | Table 5.2: SE Table | | | | | | |---------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------|--| | Descriptive<br>Information | Subject Device<br>ORTHOPANTOMOGRAPH<br>TM OP 3D LX | Primary Predicate Device<br>ORTHOPANTOMOGRAPH<br>TM OP 3D (K180947) | Predicate Device #2<br>Orthopantomograph<br>OP300<br>(K163423) | Comparison | | | Regulatory Information | | | | | | | Manufacturer | Palodex Group OY | Palodex Group OY | Palodex Group OY | Same | | | Regulation # | 21 CFR 892.1750 | 21 CFR 892.1750 | 21 CFR 892.1750 | Same | | | Regulation<br>Title | X-Ray, Tomography,<br>Computed, Dental | X-Ray, Tomography,<br>Computed, Dental | X-Ray, Tomography,<br>Computed, Dental | Same | | | Regulation<br>Class | Class II | Class II | Class II | Same | | | Product Code | OAS | OAS | OAS | Same | | | Indications for Use/Intended Use | | | | | | | Indications for<br>Use | ORTHOPANTOMOGRAPH<br>PHTM OP 3D LX is an X-<br>ray device that is<br>intended to be used for<br>imaging of adult and<br>pediatric patients.
