02 The key differentiator

Most dental panoramic and cephalometric sensors use a two-step process: X-rays strike a scintillator which converts them to visible light, which is then captured by CCD or CMOS photodiodes. PointNix's Super OLED sensor uses Cadmium Telluride (CdTe) — a direct-conversion semiconductor that turns X-ray photons straight into electrical signal, skipping the light-conversion step entirely.

Conventional

• •Two-step conversion: X-ray → light → electrical
• •Light scatters and overlaps across neighboring pixels
• •Effective X-ray absorption ~35%, requires more radiation
• •Standard for most competitor panoramic sensors

• •Single-step conversion: X-ray → electrical (no light)
• •No scatter — each pixel captures its own signal cleanly
• •Manufacturer reports ~100% X-ray absorption vs ~35% for CCD/CMOS
• •Higher contrast image quality at lower radiation dose

Absorption percentages per PointNix product documentation.

Conventional CCD / CMOS ~35% Super OLED (CdTe) ~100% Higher absorption → lower required dose No light scatter → sharper images 48 μm pixel pitch 12-bit A/D conversion

Honest note: the ~100% vs ~35% figures are published by PointNix and reflect theoretical absorption efficiency of the sensor material, not clinical outcome differences. In practice, panoramic image quality depends on the whole imaging chain (tube, collimation, processing). That said, direct-conversion sensors are a known and legitimate technical improvement over scintillator-based indirect sensors.

Honest disclosure

What pre-owned means specifically for PointNix:

• →PointNix is a smaller, specialist Korean dental imaging brand — much less international recognition than Vatech or Genoray.
• →This is both a downside (brand recognition, resale value) and an upside (lower entry price for genuine Korean-made hardware).
• →Production years of current stock typically range 2018–2023. Tube remaining life disclosed per unit, usually 75%+ on the units we select.
• →RealScan III software supports English and Korean; other language packs may need to be requested from PointNix.
• →PointNix international service network is limited — we are your primary service point for units sold through us.
• →Regulatory registration in your country is the buyer's responsibility. Some markets register PointNix directly; others may need import-as-refurbished routes.

Staged investment path

The CT sensor is detachable —
start without it, add it later.

PointNix designed the 3-in-1 with modular CT — meaning you can purchase a 2-in-1 (Pano + Ceph) configuration today and upgrade to full 3-in-1 later by adding the CT sensor, without replacing the whole unit.

Useful when: your initial case mix doesn't justify 3D imaging but you anticipate adding implants, orthognathics or airway workflows; when you want to spread the capital investment; or when you simply want the option to maintain/service the CT sensor independently.

08 FAQ Why PointNix instead of Vatech or Genoray? +

Three honest reasons:

1. Super OLED sensor. PointNix's CdTe direct-conversion technology is a legitimate technical advantage for panoramic and cephalometric image quality. Vatech and Genoray use different sensor architectures.
2. Price. PointNix doesn't command the same brand premium — you're paying for the hardware, not the reputation. Used Point 800S HD 3D Plus is typically 20–30% cheaper than comparable used Vatech or Genoray 3-in-1.
3. Upgrade path. The detachable CT sensor lets you staged-in the full 3-in-1 capability.

Three honest reasons against:

1. Smaller brand = less regulatory clearance in some markets (check your country).
2. Lower resale value if you ever upgrade or exit.
3. Less third-party service availability outside Korea.

If you want the established brands instead, look at Genoray Papaya 3D Plus or Vatech Implagraphy.

Is the Super OLED sensor actually better? +

Direct-conversion X-ray detectors (CdTe, a-Se) are a well-established concept in medical imaging — used in cardiac catheterization labs, mammography, and high-end radiography for exactly the reasons PointNix advertises: better X-ray absorption, no light-conversion step, no photon scatter between pixels. The technology is real.

Whether you'll see a clinically meaningful difference vs a well-designed CCD/CMOS panoramic depends on patient, technique, and what you're diagnosing. For general dental work most clinicians won't see obvious differences. For detailed endodontic or periodontal evaluation, the sharper pixel-level contrast can matter.

The marketing claim of "twice better than other panoramics" is PointNix's own — we report it because they print it, but we're not endorsing the exact multiplier. The underlying physics of direct conversion is sound.

How do I verify the sensor works before payment? +

Sensor health is our #1 QC concern for PointNix — because the Super OLED sensor is a proprietary specialty part that's hard to replace. Before any deposit we share for the specific unit:

• Per-pixel dark-field and flat-field test results (identifies dead or drifting pixels)
• A/D conversion linearity verification across the exposure range
• Live video of the unit performing a panoramic scan with sample DICOM export
• Sample DICOM file for you or your radiologist to open in any viewer
• High-resolution photos of the unit (real, not renders)
• Service history and tube hours reading

Can I buy the 2-in-1 version first and upgrade later? +

Yes — PointNix's product line includes the Point 800S HD Plus (Pano + Ceph only) as a 2-in-1 configuration that can be upgraded to 3-in-1 by adding the CT sensor later. We occasionally stock these 2-in-1 units at even lower pricing. Ask us if you want to start there. Just note that upgrading later means a second transaction (sensor cost + installation labor) — if you already know you want CT, buying the 3-in-1 today is typically more cost-effective overall.

What warranty and service do you provide? +

12 months parts warranty on main gantry, Super OLED sensor, and CT sensor from installation. Free replacement parts during warranty (buyer covers shipping). 24/7 remote diagnostics via TeamViewer/AnyDesk. We stock the most common PointNix wear parts in Shanghai. Note that the Super OLED sensor itself is a specialty item — failure is rare but replacement can take 2–4 weeks to source from Korea.

Country registration — is PointNix approved in my market? +

PointNix has registrations in Korea and several international markets including parts of the Middle East, Southeast Asia, and Eastern Europe. US FDA, EU MDR, and some Latin American registrations may be incomplete — this is a smaller manufacturer than Vatech/Genoray. Tell us your country when you inquire and we'll give you a realistic read on what's available. For markets without direct PointNix registration, refurbished import pathways are sometimes possible.

What's the pricing and payment terms? +

Certified pre-owned Point 800S HD 3D Plus typically ranges USD 18,000–30,000 FOB Shanghai — depending on production year, tube hours, sensor condition, and workstation specification. 2-in-1 (Pano + Ceph) configurations are available at lower price points. Standard payment: 30% deposit after documentation review, 70% before shipment. T/T preferred; L/C at sight accepted. Multi-unit orders receive volume pricing.

Installation and training? +

Remote installation support is included — our engineers guide your local technician via video call for physical assembly, software installation, sensor calibration verification, and training on RealScan III. PointNix installation is slightly more delicate than simpler single-modality units because of the Ceph arm alignment and detachable CT sensor seating. On-site installation by our engineers available for additional cost if you prefer hands-on setup.
