ACE DNTL STUDIO

Minimal-Prep Veneers

Minimal-prep porcelain veneers preserve maximum natural tooth structure by removing only 0.3 to 0.5 millimetres of enamel — less than the thickness of a contact lens. The bonded porcelain reinforces the remaining tooth and the case remains revisable. ACE DNTL STUDIO defaults to this preparation depth across the practice; aggressive preparation (1.5mm+) is refused except in clinical situations that genuinely require it, with the reason documented per case. The 100-case dataset (DOI 10.5281/zenodo.19634136) shows 66% of completed cases documented as minimal-prep or no-prep. Pricing at ACE DNTL: from €600 (pressed e.max) to €900 (hand-layered Signature porcelain) per veneer. Full upper arch (8-10 veneers) €4,800-€9,000. Two or three visits across about a month, with the temporary mock-up phase between visits.

What exactly is a minimal-prep veneer?
A veneer placed on a tooth where 0.3 to 0.5 millimetres of enamel — less than the thickness of a contact lens — has been removed to create design space for the porcelain. The bond stays on enamel (durable). The bulk of the tooth structure is preserved. The result is structurally additive: the bonded porcelain reinforces the remaining tooth.
How is minimal-prep different from no-prep?
No-prep removes zero enamel — the porcelain bonds directly to the unaltered surface. Minimal-prep removes 0.3-0.5 mm. The trade-off is design space: minimal-prep allows correction of minor proportional, alignment, and shade issues that no-prep cannot fully address. No-prep is theoretically reversible; minimal-prep is not, but the structural commitment is small.
How long do minimal-prep veneers last?
Hand-layered minimal-prep veneers, properly bonded on enamel and reviewed at six months, two years, and five years, have clinical longevity well above ten years and frequently fifteen to twenty. The longevity comes from the same restraint that produces the natural look — minimal preparation preserves the bond strength that aggressive prep destroys.
Is the studio's default minimal-prep?
Yes. Across the studio's 100-case Smile Index dataset, 39% of cases are minimal-prep, 27% are no-prep, 34% are moderate-prep. Two-thirds sit at the conservative end of the spectrum. Aggressive-prep is the exception, used only when the structural starting point demands it.
Can I have minimal-prep veneers if I have crowding or rotation?
Sometimes, when the visual correction is small and the tooth position allows ceramic to compensate via line angles and shade. Significant crowding or rotation usually needs more design space than minimal-prep allows — the case is better served by a moderate-prep approach, or by orthodontic alignment first. The threshold question is structural, decided per case.
How is the 0.3-0.5 mm preparation actually done?
Under local anaesthesia (often very mild), a fine-grit diamond bur removes the enamel surface in controlled increments. Depth-cut burs ensure consistent reduction across the visible surface. Margins are placed at the gum line or just below for aesthetic integration. The whole preparation typically takes 30-45 minutes per tooth. Hand-finishing with finer instruments creates the final smooth surface for bonding.
