Expertise in removable prosthodontic biomechanics and digital surveying. Developed the RPD Rx design workflow.
Send an intraoral scan or study cast photographs. GDC-registered dental technicians survey the case, design the framework, and return a written rationale with a prescription ready to send to your laboratory. You remain responsible for the final treatment plan.
Most problems found at try-in were present at the planning stage: an unrecognised undercut, a rest seat with too little clearance, a retainer in the aesthetic zone. We review your records against a defined survey and design protocol, so the preparation plan and laboratory prescription are agreed before treatment.
So that you know what to expect before you submit.
Every case follows the same four stages, and is recorded against a case reference.
We confirm your GDC registration and check the scan or photographs are adequate to plan safely. If not, we tell you before any design work starts.
A team member surveys the case, selects the path of insertion and draws the framework.
A second team member independently reviews the survey and design. Disagreements are resolved and noted in the rationale.
You receive the written report and prescription. You review, amend and authorise it under your own registration.
Documentation you can file in the patient record, discuss at consent, and pass directly to your laboratory.
.RPD file for RPD Rx. Amend it at the chair, add your GDC number and send it to your laboratory.Cases are reviewed by named, GDC-registered dental technology staff who also teach removable prosthodontics at university level. You can confirm any registration on the GDC online register.

Records check and refunds. We check your records before starting. If the scan or photographs are not adequate to plan the case safely, we will tell you what is needed. If the case cannot be planned from the records available, the fee is refunded in full.
The service is provided to registered dental professionals for use alongside their own clinical judgement and record keeping.
Upload your records and tell us what you would like reviewed. We verify GDC registration before any case is released for design.
Yes. The service is independent of any laboratory. The PDF prescription and survey images can be attached to a 3Shape Communicate, iTero or Medit Link case, or to a paper laboratory prescription.
Yes. Occlusal and lateral photographs of study casts, with your notes, are enough for most cases. An STL scan allows undercut depths to be measured, so the survey is more precise.
Do not enter patient names or dates of birth. In your browser, we clear the header of binary STL files, which some scanners use to store a patient name, and rename every file before upload. Files are held in an encrypted UK/EU store and permanently deleted 30 days after the review is complete.
You do. As the treating clinician you remain responsible for diagnosis, tooth preparation, consent and the final prescription. We provide a considered design and an editable file, which you review and amend before authorising it under your own registration.
We tell you what is missing before design work starts, for example a scan with incomplete palatal or lingual detail. If the case cannot be planned from the records available, the fee is refunded in full.
No. The service is provided to the treating clinician only.
