She'd been quoted a six-unit "social six" by a prior dentist and said no. Her lip line showed teeth from first premolar to first premolar when she laughed, so six wouldn't have been enough. She came back with a referring dentist who scoped the case properly: 16 units, upper 1–8 and lower 3–6, staged across multiple visits.
A few things to note before the technical work started:
- No history of bruxism in her chart, no reported morning soreness
- Enamel largely intact on the upper arch; two lower premolars had old composite that had to come off and be re-prepped
- Lip line asymmetric — right side rose about 1 mm higher on smile
- Occlusion Class I, canine-guided, no cross-bite
She wasn't after a cosmetic reset. Her exact words to the referring dentist, paraphrased back to us in the case notes: she wanted teeth that looked like her teeth would have looked without the staining. Natural, with age. That read is important — it changed the translucency targets later.
2. What the Dentist Asked For
The prescription that landed in our case-coordination team wasn't short. Here's the core of it, cleaned up for this page:
Item | Dentist's request |
|---|---|
Units | 16 total — upper 1–8, lower 3–6 |
Material | Lithium disilicate, pressed. HT ingot on the body, LT cutback on the incisal third |
Target shade | BL3 at cervical, blending to a slightly warmer BL4 at the incisal |
Stump shade (per tooth) | Mapped individually. Ranged from ND5 (two cervical) down to ND2 (incisal edges) |
Prep design | Butt-joint margin, incisal overlap, enamel-preserving facial reduction |
Delivery | Two batches — upper arch first, lower arch four weeks later |
Temporaries | Lab-fabricated bisacryl shells, cemented spot-etch, must hold four weeks |
Occlusion | Canine-guided. No working-side contact on the lateral incisors |
Records required | Full-arch digital scans, bite registration, 1:1 facial photos, approved digital mock-up |
The table is the shape of it. The reasoning underneath each line is what mattered to us. Here's how we read the prescription when it came in:
On the unit count. 16 isn't a cosmetic default. It's a function of her lip line. First-premolar-to-first-premolar on smile means anything short of 16 would have left a visible color break at the corners. Six units stops at the canines. Ten stops at the first premolars but leaves the lower arch untouched, which creates a top-bottom mismatch when she talks. The dentist walked us through this before CAD started, so we weren't guessing at where to end the design.
On the ingot strategy. HT (high translucency) on the body plus LT (low translucency) on the incisal cutback is a deliberate choice for tetracycline cases, not a stock preset. HT on the body carries the color blend across the mid-third. LT on the incisal gives us a layer that masks residual gray if any shows through near the edge, which is where tetracycline bands usually peek out at age. If we'd used LT throughout, the result would have looked opaque — too white, too flat. The patient had already told the dentist that was her nightmare outcome.
On the shade gradient. BL3 at the cervical blending to BL4 at the incisal is a reverse-of-natural gradient. Natural teeth go darker toward the gum and lighter toward the edge. The dentist flipped it on purpose: a slightly cooler cervical, a slightly warmer incisal. For this patient, with her bulky upper lip and the way light hit the cervical third first, that gradient read more natural at speaking distance than a textbook one would have. We confirmed it in the digital mock-up before pressing a single unit.
On the per-tooth stump shade. Nine of the sixteen units came back inside a two-step range on the stump scale. The other seven didn't. Two cervical uppers at ND5. Three mid-arch teeth at ND4. Four incisal-area teeth at ND2–ND3. The dentist mapped it with a shade tab held against each prepped tooth under neutral LED, photographed under polarized light, and sent us the whole set. That let us dial the thickness budget per tooth instead of pouring the same ceramic depth over every unit.
On the prep design. Butt-joint with incisal overlap is the design that gave us the best shot at keeping enamel on the facial surface. The dentist specifically wrote "enamel-preserving facial reduction" — which, in practice, means we didn't get to compensate for a dark prep by asking her to grind deeper. Veneers bonded to enamel outperform veneers bonded to dentin by a wide margin in the long-run data (preparation design and the success of dental veneers, PMC). So the ceramic has to do the masking work, not the prep.
On the batch split. Upper first, lower four weeks later. The dentist didn't want her sitting in a chair for six hours in one go, and he wanted to see the gingival response on the upper temps before committing the lower arch. He also wanted to catch any shade step at the midline early — if the upper came in warmer than expected, he had a window to adjust the lower before it was pressed.
On the temporaries. Lab-fabricated, not chairside. The dentist's note was explicit: four weeks is long for a chairside shell, and the gingival contour on the upper temp sets the gum shape the final will seat against. He wanted that shape designed from the wax-up, not improvised in the chair.
On the occlusion. Canine-guided with no working-side contact on the lateral incisors. Translation for the lab: the lateral incisors are not load-bearing in lateral excursion, so their incisal thickness can be prioritized for optics instead of strength. The canines carry the guidance, so their palatal contour is a structural request, not a cosmetic one.
On the records. Full-arch scans, bite registration, 1:1 facial photos at rest, smile, and retracted, plus a signed-off digital mock-up before pressing. He asked for the mock-up to be approved by the patient — not just by him. That meant the mock-up had to be good enough to show her, which raises the bar on the design file.
Three parts of this list changed how we actually built the case: the batch split, the per-tooth stump map, and the four-week temporary window. The next section walks through all three.
3. Our Build Process
This is the part most full veneers case pages skip. We'll go slow here, because the whole page falls apart if this section is thin.
Before any ceramic went into a press, three things sat on top of each other as the problems we had to solve. Dark substrate under thin ceramic — the two cervical teeth were ND5 under a BL3 target, a wide delta. Thin enamel in some spots, intact in others — the upper centrals had plenty of enamel, the lower premolars had dentin exposed on about 30% of the facial surface after the old composite came off. And two batches, one smile — four weeks between the upper and the lower meant color had to be locked across time, because any drift on the ingot batch, the staining paste batch, or the furnace calibration would show up later as a visible step at the midline.
Lithium disilicate can mask dark substrate when the ingot translucency and the ceramic thickness are chosen on purpose rather than defaulted (masking capacity of minimally invasive lithium disilicate restorations, PubMed). "Chosen on purpose" is the whole job. Here's what that looked like in practice.
3.1 Case intake and design file build
The case came in through our case-coordination team. Over 10 units routes through them before any CAD work starts, so the first thing we did was open the file, cross-check that everything on the prescription was actually present, and flag what wasn't. Two items came back as follow-ups: the dentist had sent facial photos but no retracted shots under polarized light, and the stump shade for one lower premolar was missing. Both arrived the next day. CAD didn't start until the file was complete.
The CAD designer built the full 16-unit wax-up as one virtual case, not as two separate arches. That matters: the midline, the incisal plane, the canine-to-canine proportion, the lip-support contour — all of these need to be solved once, with both arches in view. Splitting the arches into two separate design files would have risked a midline step we couldn't catch until try-in.
The mock-up went to the dentist. He adjusted the incisal-edge position by about 0.3 mm, softened the lateral contour, and sent it back. We applied the changes, re-rendered, and sent it to the patient through the dentist for her sign-off. She agreed. The design file was locked under the case ID, and that locked file became the reference for both batches.
3.2 Prep review and the dentin flag
Before prep day, we reviewed the planned reduction against the design file. The two lower premolars with old composite were going to expose dentin regardless of how conservatively the dentist worked, because the composite was deeper than the enamel beneath it. We flagged this to the dentist before prep, not after — because once you've already prepped, it's a different conversation.
The answer was a design adjustment on those two units: slightly thicker ceramic on the facial, a different cement shade recommendation, and a note in the file that those two teeth are bonded to a mixed enamel-dentin surface and should be tracked separately in any future recall.
3.3 Splitting the 16 units
The arch split wasn't arbitrary. Upper first, because:
- The upper arch sets the smile line. Lower units reference it, not the other way around
- Fewer units per visit means shorter chair time per appointment. 10 upper plus 6 lower is manageable. 16 at once is a 6-hour chair day most patients can't tolerate
- A four-week gap between arches lets the gingival margin on the upper settle before the lower seats. The dentist checks tissue response before committing the lower batch
Each batch was built as independently seatable. If the upper didn't fit on try-in day, the lower wasn't already milled and sitting in a box waiting. We don't start batch two until batch one is cemented and photographed. That rule is non-negotiable on cases over 10 units.
3.4 Pressing, layering, and the batch-one build
Pressing happened in our ceramics department. Same ceramist from design file to press to cutback to layering. For this case, that continuity meant the person pressing the units was the same person who'd read the stump map, which cut the number of "wait, which tooth is ND5 again?" moments down to zero.
The thickness budget was set per tooth, not per arch. The two ND5 cervical uppers got a thicker body layer because they had the most masking work to do. The incisal-area teeth got a thinner body with a longer LT cutback, because they had less to hide and more to show. Minimum ceramic thickness was never the design target — it was a floor, not a goal.
Staining and glazing were done by one ceramist, start to finish. Same furnace, same program, same lot of stain. The glaze pass was dialed down slightly from our default — the patient had asked for less surface shine, and the dentist had passed that note along in the design file.
3.5 Keeping shade consistent across four weeks
Three things we locked before batch one even shipped:
- Ingot lot number. Same lot reserved for both batches, held in-house for the full case. Not re-pulled from general stock when batch two started
- Staining paste batch. Same bottles, same jars, labeled with the case ID — not shared with other cases on the floor during the four-week gap
- Furnace program file. Exact program saved under the case ID, re-loaded for batch two with no edits
For the stump-shade side, we logged the substrate color per tooth before any cement conversation happened, then used that to pick a resin cement shade per unit. On the two ND5 cervical teeth we called for a Warm+ cement shade with a try-in paste check. The dentist agreed, swapped to Warm+ on those two, kept Neutral on the others.
3.6 Temporaries that had to hold up for four weeks
The dentist asked us to fabricate the bisacryl temporaries at the lab, not chairside. Reasons:
- Four weeks is long for a chairside temp. A lab-pressed shell holds the margin better over that span
- The gingival contour on the upper temp sets the gum shape the final will seat against. We wanted that shape designed, not improvised
- The patient had to eat, speak, work, and show up at a wedding during the temp phase. The shell had to look reasonable, not placeholder
We built the temporaries off the approved digital wax-up, then milled a transfer tray so the dentist could seat all 10 upper units in one pass. Four-week recall was scheduled before the temp was even cemented. The temps also doubled as a shade-and-shape preview: the patient wore the designed shape for four weeks before committing to the final ceramic, which cut the risk of a "I don't like it, change everything" moment on seat day down to near zero.
3.7 Version control between batches
Six changes happened between batch one and batch two. All six got logged. Here's the actual table:
# | What changed | Who flagged it | Impact on batch 2 |
|---|---|---|---|
1 | Upper central length reduced 0.4 mm after try-in | Dentist | Lower incisal reference updated |
2 | Right lateral slightly over-contoured at cervical | Dentist | Lower right cuspid cervical softened to match |
3 | Patient asked for less surface texture on the facials | Patient | Glaze protocol adjusted for batch 2 |
4 | ND5 cervical masking approved as-is | Dentist | No change — kept same thickness budget |
5 | Canine guidance confirmed on upper | Dentist | Lower cuspid palatal contour locked |
6 | Occlusal clearance adequate | Dentist | No change to lower incisal design |
Every item sits in the case file with a timestamp, who approved it, and the specific unit numbers it touches. If a lower unit comes back needing adjustment, we can walk it back to the exact decision point. That's not a tool we built for this case — it's how our case-coordination team opens any file over four units.
3.8 Batch two: pressing, layering, and seat
Batch two started the day after batch one was cemented and photographed. Same ingot lot, same stain jars, same furnace program, same ceramist. The six change items from §3.7 were applied in the design file first, then re-pressed. The glaze pass on batch two was slightly less textured than batch one, per the patient's note.
Final QC on batch two included a side-by-side shade check against the seated upper photos, under D65 and office fluorescent. The lower cleared both lighting conditions. It shipped the next morning.
4. The Finish Line
Both batches seated on the first try. The lower was cemented four weeks after the upper, as planned. One adjustment on the lower-right cuspid distal — about 0.2 mm facial reduction the dentist handled chairside, no return to the lab. Full 16-unit full veneers case closed in two cementation appointments plus one prep appointment per arch.
What we're not claiming on this page:
- We're not claiming a specific lifespan number for this patient. Published survival data for porcelain laminate veneers sits in the mid-90s percent range at 10 years in the general systematic reviews, but that's a population figure, not a promise for one person. Enamel bonding, bruxism history, hygiene — all of those shift the number up or down.
- We're not claiming the shade match is perfect under every lighting source. We matched to the agreed-upon targets under D65 and office fluorescent. The dentist signed off on both.
What we are claiming:
- Both batches fit on the day they were tried in
- The upper-to-lower shade step at the midline was inside the margin the dentist considered acceptable at seat
- All six change items between batches got absorbed without delaying the lower delivery
5. Try-In Feedback: Patient and Dentist
Try-in happened in two sittings — one for the upper, one for the lower four weeks later. The feedback below is paraphrased from the dentist's chair notes and his follow-up email to our case-coordination team. We're not quoting direct speech, because this is a lab page, not a testimonial page.
From the patient, upper try-in. She told the dentist the shape looked like her teeth. That was the single thing she said twice, and it was the single thing we'd been designing toward. She asked for slightly less shine on the facial surface — she thought the glaze read a little too polished for her age. The dentist flagged it in the case file, and we adjusted the glaze protocol for batch two. She did not ask to change the shade, the length, or the contour.
From the patient, final seat. She said the lower matched the upper, which is the sentence a lab wants to hear after a four-week gap. She noticed the slightly softer finish on the facials and liked it better than the batch-one surface. She mentioned the temporaries had held up through the full four weeks without chipping or discoloring, which she had not expected.
From the dentist, upper try-in. Fit was clean on all 10 units — no adjustment needed on the margins, no proximal rock, no occlusal interference beyond what he'd planned. He flagged the right lateral as slightly over-contoured at the cervical and asked us to carry the correction into batch two so the lower cuspid cervical would match. He confirmed the ND5 masking was holding and said the body shade read right under all three of his operatory lights.
From the dentist, final seat. All six lower units seated on the first try. The lower-right cuspid distal needed a 0.2 mm chairside adjustment, which he handled without returning the unit. Midline shade step was inside what he'd called acceptable at the design stage. He wrote back the following week to say the patient had been through a two-week recall with no complaints, no sensitivity reports, and no cosmetic second-guessing.
What the feedback changed for us. Two things. First, the "less shine on the facial" note went into our case-coordination intake sheet as a question we now ask upfront on any full veneers case over 10 units — some patients want polish, some want a softer finish, and the design file should capture that before we press. Second, the lab-fabricated four-week temporary performed well enough that we've written up the protocol as our default recommendation for any case with a staged batch gap over three weeks.
6. What This Case Says About Our Full Veneers Work
Three things, each one tied back to how our lab is actually set up.
All of this happened in one building. CAD, milling, pressing, layering, glazing, QC — same facility in Shenzhen, under Istar's roof. The ingot sitting in the batch-two tray came from the same lot we pulled for batch one, because we don't ship cases out to a third-party sub-lab and we don't swap suppliers mid-case. End-to-end in-house is how we hold the thread across weeks.
Around 460 technicians means someone owns each step. The CAD designer who built the wax-up isn't the person running the furnace. The ceramist who layered the upper is the same person who layered the lower. Four weeks later, same hands. On a long full veneers case, continuity of the technician matters more than the brand on the ingot box.
The records habit came before we needed it. The stump-shade map, the batch log, the version table — none of these are extras we bolted on for this case. They're how our case-coordination team opens any file over four units. If you send us a full veneers case, you get this level of documentation back by default, not on request.
7. A Quick Note on Terms
Worth a short clarification, because "full veneers" gets stretched in a few directions online.
A full veneers case means every tooth across the smile zone gets a veneer — not a few. It does not mean full-coverage around the back and biting surfaces of the tooth. A veneer still covers only the facial surface, maybe wrapping slightly to the incisal edge if the prep design calls for incisal overlap. The lingual side stays untouched. If a tooth needs full coverage all the way around, that's a crown, not a veneer, and it's a different prescription (Cleveland Clinic on dental veneers).
This distinction matters when you're scoping a case. A tooth with a cracked lingual cusp isn't a full veneers candidate. It's a crown candidate. We'll flag that in case review and send the prescription back before any CAD work starts.
8. Working With Us on a Full Veneers Case
If you're scoping a full veneers case for your patient, here's what we need in the file:
- Full-arch digital scans, upper and lower
- Bite registration (digital or PVS)
- 1:1 facial photos — rest, smile, retracted
- Stump shade per tooth, even if two or three units share the same reading
- Target shade, including gradient if applicable
- Prep design preference (butt-joint, feather, incisal overlap)
- Occlusal scheme and any guidance preferences
- Delivery preference — one batch, two batches, or more
- Temporary expectations — chairside, lab-fabricated, duration
Cases over 10 units route through our case-coordination team before any CAD work starts. We flag anything missing, propose a batch split if you haven't specified one, and send a timeline back within two business days.
Factory visits are open — in person or by video — for dentists, clinics, and partner labs. Both Shenzhen and Huizhou facilities are set up for walk-throughs. Request a case assessment and we'll take it from there.
