Khai Nguyen Dental Lab would like to thank the clinicians at Paris Dental for their trust, and for sending back the clinical images taken after delivery.
The case
This was an All-on-X full-arch implant restoration, built on titanium thimbles as the connection between the implants and the ceramic superstructure.
Why the connection matters
In full-arch implant work, error does not distribute the way it does on natural abutments. One implant that is not passively seated loads the whole framework, and the consequence usually appears later as a loosening screw or a ceramic fracture rather than at the moment of delivery.
Using intermediate titanium thimbles separates the metal interface with the implant from the ceramic outside it. That lets the lab control fit at the contact surface while keeping enough room to build form and shade in the esthetic layer. It is the reason this family of solutions is used so often on full-arch cases that have to deliver both durability and esthetics.
Why clinical feedback is worth having
The post-delivery images the clinician sent back are valuable data for a lab. A restoration on the model and the same restoration in the mouth sit in completely different lighting, and only a clinical photograph shows how shade, translucency and the relationship with lip and gingiva actually read.
We are grateful for feedback like this, because it is how a lab calibrates its shade work for the cases that follow.

What the lab needs to start an All-on-X case
Our original Facebook post (November 2025) records only our thanks and the clinic’s feedback photographs. It does not state the number of implants, the material or the shade, so what follows is our general workflow for full-arch implant cases, not a description of this one.
- Implant positions: a splinted impression, an intraoral scan with scan bodies, or intraoral photogrammetry (IPG) data. Each has limits across a fully edentulous arch; see IPG for full-arch implants.
- Soft tissue and opposing arch: a soft-tissue scan, the opposing arch and the bite. If the patient is comfortable in a provisional, scan that too. It is the most useful record of vertical dimension, smile line and lip support.
- Facial photographs so midline, smile line and occlusal plane can be checked against the design.
- FP1, FP2 or FP3: agree the route with the lab early, because it changes both the design and the finishing work. See All-on-4 in FP1.
What we check at the lab
- Digital design: All-on-X design is returned within 24 hours (CAD design service). We check screw access positions, tooth position against the lip, and whether the intaglio surface can be cleaned.
- Passive fit: the framework is verified on the model, for example with a single-screw (Sheffield) test, before the ceramic is finished. This is the step that relates directly to the connection discussed above.
- Tissue surface: polished carefully to limit plaque accumulation.
- Try-in on the model and photographs before shipping. Timing for full-arch cases is agreed per case and normally includes one try-in before finishing.
