109FIFTY · 01
Non- to Minimal-Prep: tissue preservation as the standard
Maximum precision. Minimal preparation.
109FIFTY plans definitive veneers as fully additive non-prep or selective minimal-prep restorations when clinical conditions allow. If a circumferential full-crown preparation is required, the restoration is not called a 109FIFTY veneer. Enamel preservation is supported as a prognostic factor – without an individual success guarantee.
At 109FIFTY, preparation is not done solely out of routine or to simplify fabrication. The space required is derived from the planned outcome and the clinical findings. Non-prep or selective minimal-prep is the standard. A circumferential stump preparation for a full crown is something else and is not called a veneer. Tissue preservation has the highest priority.
109FIFTY principle
Why preparation must remain the exception
Any broad surface reduction costs enamel, which is especially valuable for adhesive cementation. That is why the first check is whether form, position, colour, space and function allow an additive restoration.
Minimal-prep means a selective preparation guided by the planned outcome – only where space, path of insertion, margin design, colour control or functional safety require it.
109FIFTY plans definitive veneers as fully additive non-prep or selective minimal-prep restorations when clinical conditions allow. If a circumferential full-crown preparation is required, the restoration is not called a 109FIFTY veneer.
Limits and framing
Aligners and tooth position – when space is missing
Orthodontic pre-treatment can, in selected cases, create restorative space and thereby enable a more tissue-preserving later restoration. A fully preparation-free restoration is not guaranteed by that alone.

109FIFTY principle
Ceramic veneers only – quality standard
Definitive 109FIFTY veneers are planned in ceramic – not composite. For 3D simulations we use hybrid materials so form, length and effect can be assessed on the patient before definitive ceramic is made.
Damaged veneers are replaced, not repaired. Where findings require it, ceramic partial crowns may also be considered – always defect-oriented, not as a standard crown “as it used to be”.
109FIFTY principle
Direct coordination with thin ceramic
With very thin ceramic, small differences in form, length, colour and translucency have a large effect. That is why these features are coordinated directly with the patient in demanding cases.
Indication
When it may fit.
And when it may not.
- Expectation of standard preparation “as crowns used to be done”
- Strongly proclined or heavily crowded starting situation without pre-treatment
- Colour goal that would only be reachable with clearly more material thickness and preparation – then honest indication clarification
Process
From standard to decision
- 01
Diagnostic capture
Capture expression, facial dynamics, lip movement, speech, proportions, existing tooth features, enamel, bite and desired self-image – before preparing.
- 02
Understand the patient directly
The dental technician experiences the patient directly and understands the target vision themselves – not only the description relayed by the dentist.
- 03
Make the goal visible in the 3D try-in
Smile design and 3D simulation show form, length and lip effect before irreversible steps. The principle remains: make the goal visible first – with digital technique more precise and traceable than the classic, labour-intensive wax-up/mock-up.
- 04
Decide non-prep, minimal-prep or pre-treatment
Additive ceramic, minimal-prep, aligner pre-treatment, discreet bite elevation or a combination – always with tissue preservation as the guiding measure. Full-crown preparation ≠ 109FIFTY veneer.
- 05
Try in chairside and cement adhesively
Jointly check form, length, colour, surface and lip effect; then cement adhesively and provide risk-based follow-up care.
Materials & technique
Material logic
- Definitive 109FIFTY veneers are planned in ceramic
- Lithium disilicate (e.g. IPS e.max® CAD or Press) typically for thin adhesive restorations
- Zirconia when implants are also to be restored in a full-mouth rehabilitation
- Feldspathic ceramic when maximum individual layering is desired
- Hybrid materials for 3D simulations – not as definitive veneers
Limits and framing
What to keep in mind.
- Forced non-prep can lead to unfavourable contours – then controlled minimal-prep is more honest.
- No individual longevity guarantee.
- Care intervals are set on a risk basis – not as a blanket rule for every case.
Care · quality standard
The ceramic itself does not develop caries. Tooth and gingiva remain biological tissue.
Veneers do not protect against caries, gingivitis or periodontitis. Transitions between tooth, ceramic and gingiva must be kept biofilm-free. The review and cleaning interval is risk-based – not a blanket higher professional cleaning frequency for all veneer patients.
Qualified prophylaxis
Complex restorative cases should be cared for by specially trained prophylaxis staff. Dental hygienists hold the highest level of the modular training system and are particularly qualified for comprehensive prophylaxis and periodontal pre- and aftercare. Dental prophylaxis assistants may also perform professional cleaning within the legally permitted framework under dental responsibility. 109FIFTY defines care by a dental hygienist or comparably qualified prophylaxis staff as its own quality standard – not as a legal exclusivity.
Home care
- Electric toothbrush: Can reduce plaque and gingivitis slightly more on average than a manual brush; correct use remains decisive. Twice daily with fluoride toothpaste, without excessive pressure.
- Interdental brushes matched to the embrasure width; floss especially for tight contact points.
- Floss at tight contacts: guide controlled through the contact point, then wrap C-shaped around each tooth surface and clean vertically.
- Do not: snap into the gingiva or saw horizontally between teeth. Short: through the contact point – not through the gingiva. No sawing.
Interval and focus of professional cleaning are set by the treating practice according to risk and findings.
Knowledge
Frequently asked questions.
Is non-prep always better than minimal-prep?+
109FIFTY plans definitive veneers as non-prep or selective minimal-prep when conditions allow. Within that standard, minimal-prep can be biologically more sensible than forced non-prep with overcontour. Space is often created with discreet bite elevations via tabletops in the posterior – especially when larger changes are desired in the aesthetically visible area. Circumferential full-crown preparation is not called a 109FIFTY veneer.
Why ceramic as the definitive veneer?+
Definitive 109FIFTY veneers are planned in ceramic. Typical composite or resin veneers are often less colour-stable, can yellow at the margins and look bulky with large form changes. For 3D simulations we use hybrid materials. Damaged veneers are replaced, not repaired; partial crowns may be considered when needed. Clinical long-term comparisons support ceramic veneers in suitable indications (including RCT data) – without an individual guarantee.
What about aligners before veneers?+
Orthodontic pre-treatment can, in selected cases, create restorative space. A fully preparation-free restoration is not guaranteed by that alone. Limited clinical evidence / case reports.
Why chairside for thin veneers?+
With very thin ceramic, small differences in form, length, colour and translucency have a large effect. That is why these features are coordinated directly with the patient in demanding cases.
