The no prep approach, when and how
Indications for no prep protocols are quite strict and may be summarized as follows:
– Post orthodontic treatment needing some small improvement
– Little smile design corrections (embrasures, diastemas, etc…)
The no prep concept is nowadays heavily trending, but for proper planning the practitioner should have a precise idea of dos and donts.
This article is made to highlight the use of chips in esthetic treatment.
TIPS of the case:
– basic way of production in the lab restoration: press and polish
– bleach before starting the case to increase esthetic integration of chips
– bonding sequences starting by chips first and laminate after.
No prep restorations can be very precious in contemporary treatment planning to solve some everyday cases, though it is important to integrate this type restoration in a basic workflow where it is simple for both the lab and the dentist in order to do it in a feasible and repeatable way.
The role of the dentist as a smile architect is fundamental to visualize the ideal pink/black/white ratio for top quality esthetics and biological preservation.
