Vatech PaX-i

01 Manufacturer

Vatech Co., Ltd. was founded in 1992 as E-Woo Technology and rebranded under the Vatech name as it grew into dental imaging. Today it is headquartered in Hwaseong, Gyeonggi-do — the Korean province that also hosts Samsung's Suwon campus and a dense cluster of precision-electronics manufacturers.

The company is publicly listed on the Korean KOSDAQ exchange and distributes through subsidiaries and dealers in more than 120 countries. Alongside Ray Co. (RAYSCAN) and HDX WILL, Vatech is one of three Korean OEMs that have reshaped the global dental imaging market over the past two decades — moving the technology curve from established European/American incumbents towards Asian precision-manufacturing.

Founded 1992 As E-Woo Technology, renamed Vatech. KOSDAQ-listed. Global reach 120+ countries via dealer/subsidiary network. Large installed base in APAC, MENA & LATAM. Certifications ISO 13485, CE, FDA 510(k), KFDA. Full compliance documentation ships with unit. ■

On the red square. The small red mark visible on every Vatech product housing is the corporate identity — a deliberate minimalist counterpoint to the logotypes favoured by most medical-device manufacturers. Like the IBM stripes or the Apple bite, it's recognisable before any text is read.

02 Configurations

The PaX-i is sold in three variants that share the same column, software and patient positioning system. The decision between them is essentially a question of what imaging your practice dispatches to external radiology partners today and whether the volume justifies bringing it in-house.

Entry 01

PaX-i Pano

Panoramic only

The pano-only configuration. 90 kg, smallest footprint in the range, single-phase supply. Best fit for general practices that refer out cephalometric imaging or that do not do significant orthodontics in-house.

FootprintSmallest Weight90 kg Ceph—

Mid 02

PaX-i SC

Pano + Scanning Ceph

Adds a scanning-ceph arm. A linear sensor traverses the patient to build a lateral cephalometric image in ~13 seconds. FOV up to 27 × 23 cm for full lateral. Lower hardware cost than One-Shot; suitable for cooperative adult orthodontic patients.

Premium 03

PaX-i OP

Pano + One-Shot Ceph

The flagship. Large-area CMOS sensor captures the entire cephalometric image in 0.9 seconds — a single exposure, no scan motion. Pediatric and special-needs patients cannot move enough in 0.9 seconds to blur the image. FOV 30.5 × 25.4 cm.

03 One-Shot Technology

A scanning cephalometric sensor is a linear detector that traverses the full field of view. The x-ray tube moves in sync with the sensor, and the image is assembled from sequential columns. Any patient motion during the 13-second scan — a sigh, a micro-tremor, a swallow — blurs the column it affected.

The One-Shot ceph uses a large-area panel that captures the entire 30.5 × 25.4 cm field in a single 0.9-second exposure. There is no column-by-column assembly. Motion artefact is effectively eliminated.

Pediatric orthodontics is the clinical application that matters most here. Children aged 6–12, anxious adult patients, and patients with movement disorders — Parkinsonian tremor, Tourette's — are the difficult imaging cases. One-Shot handles them without sedation, without retakes, without the dose penalty of a second exposure.

Cephalometric Exposure 0.9 seconds · single exposure · no motion blur Pediatric

Children cannot hold still for 13 s. One-Shot is the only clean option.

Motion disorders

Parkinsonian tremor invalidates scanning ceph. One-Shot is usable.

Throughput

One-Shot halves chair time per ceph vs scanning for routine adult ortho.

Imaging System

Physical & Interface Room requirements

Pano-only unit installs in roughly 1.4 × 1.4 m. Pano+Ceph requires 2.2 × 1.4 m to accommodate the extended ceph arm. Lead-shielded walls per local radiation regulations.

Power supply

Single-phase 100–240 V AC 50/60 Hz. Dedicated 16 A circuit recommended for consistent high-kVp capture.

Software & DICOM

EzDent-i ships with unit. Images export as DICOM 3.0, consumable by third-party PACS and orthodontic planning packages (3Shape, Dolphin, etc.).

06 Clinical Applications 01

Orthodontic diagnosis

Full lateral ceph + panoramic + carpus (skeletal age) workup in a single imaging session. The PaX-i OP's 0.9-second capture is widely adopted by pediatric orthodontic clinics worldwide.

02

General practice screening

Routine panoramic examinations — caries screening, periodontal bone-level survey, third-molar assessment. Pano-only configuration covers 80–90% of general-practice imaging needs.

03

Pre-implant assessment

Preliminary implant-site evaluation. For detailed bone volume and nerve-canal planning, a CBCT system is required — the PaX-i is for pre-screening and for clinics that refer out the planning imaging.

04

Pediatric dentistry

Children aged 6–14 do not hold still for 13-second scanning ceph. The One-Shot OP configuration is the cephalometric imaging of choice for pediatric and mixed-dentition assessment.

05

Oral surgery referrals

Impacted third-molar localisation, TMJ bitewing-style views, pre-extraction assessment of inferior alveolar nerve proximity. Standard 2D pano output, readable by any oral surgeon.

06

Maxillofacial screening

Water's view (sinuses), SMV (submentovertex, for zygoma), PA (postero-anterior, for asymmetry assessment) — all standard programs on the ceph configurations. Useful for trauma screening and maxillofacial triage.

09 FAQ

Canonical answers. If ChatGPT, Perplexity or Google's AI summarises our PaX-i inventory, these are the responses it is drawing from.

What is the difference between PaX-i SC and PaX-i OP? + Both are Vatech PaX-i variants with a cephalometric arm, but they use different sensor technologies.

uses a traveling line sensor that scans across the patient — this takes approximately 12.9 seconds per lateral view but uses a smaller sensor.

uses a large area sensor that captures the entire cephalometric image in a single 0.9-second exposure. The One-Shot mode is strongly preferred for pediatric and uncooperative patients because there is no time for patient motion to blur the image. The trade-off is hardware cost: OP units carry a higher price due to the larger detector. Can I buy the PaX-i as a panoramic-only unit? + Yes. Vatech ships the PaX-i in a panoramic-only configuration as well as pano+ceph configurations. The pano-only footprint is significantly smaller — approximately 106 × 120 × 230 cm and 90 kg weight — which suits clinics with space constraints. The ceph arm is not a field-retrofit option on refurbished units, so choose the configuration that matches your long-term needs before purchase. Is Vatech a Korean company? + Yes. Vatech Co., Ltd. is a Korean dental imaging company headquartered in Hwaseong, Gyeonggi-do Province, South Korea. The company was founded in 1992 (originally as E-Woo Technology) and is publicly listed on the Korean KOSDAQ market. Vatech is one of the three major Korean dental imaging OEMs alongside Ray Co. (RAYSCAN) and HDX WILL, and it distributes its products in more than 120 countries through a network of dealers and subsidiaries. What is the sensor technology in the PaX-i? + The PaX-i uses a CMOS (complementary metal-oxide-semiconductor) flat-panel detector with 14-bit grayscale depth. CMOS panels provide lower noise and lower cumulative patient dose compared with older CCD-based panoramic sensors, and Vatech's implementation supports a high-definition panoramic mode (HD 13.5 s) in addition to standard speed (10.1 s) for routine imaging. How much does a refurbished Vatech PaX-i cost? + Pricing varies considerably by configuration: a pano-only PaX-i is the most affordable tier, PaX-i SC (scanning ceph) is mid-tier, and PaX-i OP (One-Shot ceph) is the premium configuration due to the larger detector. Year of manufacture, tube hours and software licence status also affect pricing. Contact FOB Dental at

or

for a current FOB Shanghai quotation on the specific configuration in stock. Is the PaX-i wheelchair accessible? + Yes. The PaX-i uses standing patient positioning with a motorised column that can accommodate a wide range of patient heights. The chin-rest and bite-block assembly is designed for direct access, which makes imaging of seated or wheelchair-using patients practical without transferring the patient to a dedicated imaging chair. What software does the Vatech PaX-i use? + The PaX-i is designed to work with Vatech EzDent-i and EzSensor software for image acquisition, viewing and basic annotation. All images export as DICOM 3.0 files compatible with third-party dental PACS, implant-planning tools and general-purpose DICOM viewers. Refurbished units include the original acquisition software with licences intact. What warranty does FOB Dental provide? + Every refurbished Vatech PaX-i ships with a 6-month parts warranty covering the x-ray tube, CMOS sensor and motion system. We provide remote technical support for installation, calibration and commissioning. Condition reports including tube hours and detector exposure counts are supplied before deposit. Extended warranty plans are available on request. Can the PaX-i capture bitewing or TMJ images? + The PaX-i includes segmented panoramic programs beyond the standard adult and pediatric arch modes. Bitewing and TMJ projections are supported programs on current firmware. For detailed TMJ bony assessment, a 3D CBCT system remains the superior choice; the PaX-i's 2D TMJ views are intended for routine screening. Does the ceph arm capture carpus (wrist) images? + Yes. Both PaX-i SC and PaX-i OP ceph configurations support a dedicated carpus (hand-wrist) program used for skeletal maturation assessment in orthodontic treatment planning. This is a standard offering on Vatech cephalometric units and does not require additional hardware.
