These terms establish the rights, obligations, responsibilities, billing procedures, and other conditions governing the relationship between Xviahlink and Customers using the Service.

“Customer” means a dental laboratory, dental practice, dentist, dental professional, or other authorized business entity that uses the service.

Article 3. Eligibility and Account Registration

The service is intended for dental laboratories, dental practices, dentists, dental professionals, and other authorized business users.

The customer represents and warrants that all registration information provided to Xviahlink is accurate, complete, and current.

The customer further represents that it has authority to enter these terms and will maintain all licenses, registrations, permissions, and professional authorizations required for its business and use of the service.

The customer is responsible for maintaining the confidentiality of its account credentials and for all activity conducted through its account.

The customer shall promptly notify Xviahlink of suspected unauthorized account access.

Xviahlink may refuse, suspend, or terminate an account if the customer provides materially inaccurate information, violates these Terms or applicable law, fails to make required payments, engages in fraudulent activity, or creates a material security or operational risk.

Article 4. Services

Xviahlink may provide digital dental CAD design services, including services relating to crowns and bridges, implants, custom abutments, anterior cases, models, full-arch and All-on-X cases, implant bars, and other supported dental design categories.

The service may also include design revisions, digital file delivery, case tracking, communication tools, priority processing, and customer support.

Xviahlink may use employees and independent service providers, including Xviah Inc, as well as authorized third-party CAD designers and design companies to perform all or part of the Service. Such providers may be located outside the United States and are subject to applicable contractual confidentiality, security, and HIPAA requirements.

Article 5. Customer Responsibilities

The customer is responsible for providing complete, accurate, usable, and sufficient case files and design instructions.

Depending on the case, required information may include tooth number, digital scans, material selection, shade, margin information, implant system and component information, design preferences, and other information necessary to complete the requested design.

The customer is responsible for reviewing all information before submitting the case.

Xviahlink is not responsible for errors, delays, redesigns, additional charges, or manufacturing problems caused by incomplete, inaccurate, corrupted, incompatible, or poor-quality case files or customer instructions.

Article 6. Case Submission, Acceptance, Cancellation, and Charges

Submission of a case does not constitute acceptance of the case by a designer.

After submission, the case may remain in pending status until an available designer reviews and accepts it.

The customer may cancel a case at any time before case acceptance without being charged the applicable design fee.

If payment for such case has already been collected before cancellation, the applicable design fee will be refunded or credited, subject to reasonable payment-processing limitations.

Once a designer accepts the case, the case becomes billable, and the applicable design fee is charged or added to the customer’s account.

Cancellation after case acceptance does not eliminate the customer’s obligation to pay the applicable design fee, even if the design has not yet been completed, because design capacity has been committed and work may already have commenced.

Rush and super rush surcharges also become billable upon case acceptance.

Xviahlink may decline a case if the files are incomplete or unusable, the requested service is unavailable, the case falls outside the service scope, or Xviahlink reasonably determines that the requested turnaround cannot be met.

Article 7. Turnaround Times and Priority Services

Normal Service

Normal Service is intended to support an overnight workflow. A case submitted around the customer’s end of business day is generally intended to be completed and available for review at or around the beginning of the customer’s next business day. The target turnaround time is approximately eight (8) hours.

Rush Service

Rush service has a target turnaround time of approximately three (3) to four (4) hours following case acceptance. Rush service is subject to an additional 25% charge based on the applicable standard design fee.

Super Rush Service

Super rush service has a target turnaround time of approximately one (1) hour following case acceptance. Super rush service is subject to an additional 50% charge based on the applicable standard design fee.

Calculation of Turnaround Time

Turnaround time begins when the required case files and design instructions have been received in usable form, and the assigned designer has accepted the case. If clarification, replacement files, new scans, additional instructions, or other information is required, the turnaround period may be paused until the necessary information is received. Rush and super rush services are subject to designer availability, case type, file quality, and case complexity. All stated turnaround times are service targets rather than guarantees, unless Xviahlink expressly agrees otherwise in writing.

Article 8. Revisions

The Customer may request a reasonable revision if a delivered design does not conform to the original design request.

A revision resulting from an error attributable to Xviahlink or the designer may be provided without additional charge in accordance with Xviahlink’s applicable revision policy.

A revision may result in additional charges or constitute a new case if it is due to new scans, changed preparation, changed prescriptions, changed materials, changed design instructions, changed implant components, or any other material change initiated by the customer.

Article 9. Fees, Invoicing, and Payment

The customer agrees to pay all applicable fees for accepted cases and other services purchased through Xviahlink.

A case becomes billable upon case acceptance.

Normal service is charged at the applicable standard design fee.

Rush service is charged at the standard design fee plus twenty-five percent (25%).

Super rush service is charged at the standard design fee plus fifty percent (50%).

Unless otherwise agreed in writing, Xviahlink operates on a monthly billing cycle.

Xviahlink will generally issue an invoice on the first (1st) day of each calendar month for billable cases and other applicable charges incurred during the preceding billing period.

The customer is required to maintain a valid payment method, including a valid credit or debit card, on file with Xviahlink.

By providing a payment method and using the service, the customer authorizes Xviahlink and its authorized payment processor to automatically charge the payment method on file on or around the fifth (5th) day of each calendar month for the amount shown on the applicable invoice.

The customer is responsible for ensuring that its payment and billing information remains accurate, complete, and current.

If an automatic payment is declined, rejected, or otherwise unsuccessful, Xviahlink may notify the customer and request an updated payment method or other payment arrangement. Xviahlink may temporarily suspend the submission, acceptance, or processing of new cases until outstanding amounts have been paid.

The customer is responsible for reviewing each invoice and promptly notifying Xviahlink of any suspected billing discrepancy. A billing inquiry or dispute concerning a portion of an invoice does not relieve the customer of its obligation to pay any undisputed amounts when due.

Xviahlink may modify its billing cycle, invoice schedule, payment methods, or payment terms from time to time. Xviahlink will provide reasonable advance notice of any material change affecting existing customers.

The customer is responsible for any applicable sales, use, excise, or similar taxes imposed on the customer’s purchase or use of the service, except for taxes imposed on Xviahlink’s net income.

Article 10. Refunds

A case cancelled before case acceptance is eligible for cancellation without the applicable design fee.

A case cancelled after case acceptance remains billable.

If Xviahlink is unable to perform an accepted case for reasons solely attributable to Xviahlink, Xviahlink may cancel the charge, issue an account credit, or issue a refund as appropriate.

If a rush or super rush case cannot be completed within the applicable priority timeframe solely because of circumstances attributable to Xviahlink, Xviahlink may refund or credit the applicable priority surcharge.

Delays resulting from customer instructions, case complexity, missing files, inaccurate information, new scans, revisions, third-party failures, or circumstances beyond Xviahlink’s reasonable control do not automatically qualify for a refund.

Article 11. Patient Information and HIPAA

Customers may submit patient-related information in connection with a Case.

The customer represents that it has all rights and legal authority necessary to submit such information to Xviahlink.

Where Xviahlink creates, receives, maintains, or transmits Protected Health Information (“PHI”) on behalf of a HIPAA covered entity, such processing will also be governed by the applicable HIPAA Business Associate Agreement.

Xviahlink uses case IDs, access controls, and other measures intended to reduce unnecessary disclosure of patient-identifying information.

The customer should submit only information reasonably necessary for the requested service.

Article 12. Clinical and Professional Responsibility

Xviahlink provides digital dental CAD design services. Xviahlink does not diagnose patients, prescribe treatment, or provide medical or dental treatment.

The customer remains solely responsible for diagnosis, prescription, treatment planning, clinical decisions, case specifications, verification of design requirements, and final design approval.

Every design must be reviewed and approved by the customer before milling, printing, manufacturing, clinical use, delivery, or placement in a patient.

Xviahlink does not assume responsibility for the clinical suitability of a design based on incomplete, inaccurate, or insufficient customer-provided information.

Article 13. Intellectual Property

viahlink.com, including its website, software, interface, logos, trademarks, graphics, text, and related technology, is owned by or licensed to Xviahlink.

The customer retains its applicable ownership rights in customer-provided case files.

The customer grants Xviahlink and its authorized designers and service providers the limited rights necessary to access and process such files for purposes of providing the service.

Subject to payment of applicable fees, the customer may use delivered designs for the relevant case and legitimate dental laboratory, manufacturing, or clinical purposes.

Article 14. Confidentiality

Each party shall use commercially reasonable measures to protect confidential information of the other.

Confidential information may include case files, patient information, business information, pricing information, technical information, and non-public communications.

Confidentiality obligations survive termination for as long as the applicable information remains confidential.

Article 15. Designers and Third-Party Service Providers

Xviahlink may engage employees and independent service providers, including Xviah Inc, as well as overseas CAD designers and other qualified third-party service providers. The Korean service provider is a legally separate company and is not treated as an affiliate merely because the companies may share a representative or management personnel.

Access to case information shall be limited to information reasonably necessary for the applicable work.

Where a third-party service provider creates, receives, maintains, or transmits PHI on behalf of Xviahlink and qualifies as a HIPAA subcontractor, Xviahlink will require applicable contractual safeguards.

Article 16. Prohibited Activities

The customer shall not use the service unlawfully, submit fraudulent information, compromise platform security, share account credentials without authorization, introduce malicious software, infringe third-party rights, misuse patient information, or circumvent Xviahlink to avoid applicable fees by directly engaging a designer introduced through the service.

Article 17. Service Availability

Xviahlink will use commercially reasonable efforts to maintain the service.

However, Xviahlink does not guarantee uninterrupted or error-free service availability.

The service may be interrupted by maintenance, technical problems, security incidents, internet failures, third-party services, natural disasters, or other circumstances beyond Xviahlink’s reasonable control.

Article 18. Disclaimer

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SERVICE AND ANY DESIGNS PROVIDED THROUGH THE SERVICE ARE PROVIDED ON AN “AS IS” AND “AS AVAILABLE” BASIS.

XVIAHLINK DOES NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR AVAILABLE AT ALL TIMES, OR THAT ANY DESIGN WILL BE SUITABLE FOR A PARTICULAR MANUFACTURING OR CLINICAL PURPOSE WITHOUT REVIEW AND APPROVAL BY THE CUSTOMER.

XVIAHLINK DISCLAIMS ALL IMPLIED WARRANTIES, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT, TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW.

THE CUSTOMER IS RESPONSIBLE FOR REVIEWING AND APPROVING EACH DESIGN BEFORE MILLING, PRINTING, MANUFACTURING, DELIVERY, OR CLINICAL USE.

Nothing in these terms excludes or limits any warranty, right, or liability that cannot lawfully be excluded or limited.

Article 19. Limitation of Liability

To the maximum extent permitted by applicable law, Xviahlink shall not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages arising from or relating to the service.

To the maximum extent permitted by applicable law, Xviahlink’s aggregate liability arising out of or relating to these Terms or the Service shall not exceed the total amount actually paid by the customer to Xviahlink during the twelve (12) months immediately preceding the event giving rise to the claim.

Nothing in these Terms limits liability that cannot legally be limited or excluded.

Article 20. Indemnification

The customer agrees to indemnify and hold harmless Xviahlink, its affiliates, officers, directors, employees, contractors, and service providers from third-party claims arising from the customer’s violation of these Terms or applicable law, unauthorized disclosure of patient information, infringement by customer-provided materials, or improper manufacturing or clinical use of a design.

Article 21. Suspension and Termination

Xviahlink may suspend or terminate an account for material breach, non-payment, fraud, misuse of the service, material security risk, or violation of applicable law.

Termination does not affect amounts already due for accepted cases.

Provisions intended by their nature to survive termination will remain in effect.

Article 22. Force Majeure

Xviahlink shall not be liable for failure or delay caused by circumstances beyond its reasonable control, including natural disasters, war, governmental actions, labor disputes, telecommunications failures, power failures, cybersecurity events, or third-party infrastructure failures.

Article 23. Governing Law

These Terms are governed by the laws of the State of New Jersey, without regard to its conflict-of-laws principles.

Article 24. Dispute Resolution

Before commencing any formal legal proceeding arising out of or relating to these Terms or the Service, the parties agree to make reasonable good-faith efforts to resolve the dispute through informal discussions.

A party seeking to initiate a dispute shall provide written notice to the other party describing the nature of the dispute and the requested resolution. The parties will have thirty (30) days from receipt of such notice to attempt to resolve the dispute informally.

If the dispute cannot be resolved through informal discussions within such thirty (30)-day period, either party may pursue available legal remedies.

To the extent permitted by applicable law, any legal action or proceeding arising out of or relating to these Terms or the Service shall be brought exclusively in the state or federal courts located in the State of New Jersey, and each party consents to the personal jurisdiction and venue of such courts.

Nothing in this Article prevents either party from seeking temporary, preliminary, or other injunctive relief where necessary to prevent immediate or irreparable harm.

Article 25. Changes to These Terms

Xviahlink may update these terms to reflect changes to the service, pricing, billing practices, technology, operations, or applicable law.

Material changes will be communicated through reasonable means where required by applicable law.
