A systematic approach to minimal veneer preparation

Advances in dental materials and fabrication techniques have now enabled technicians to create Porcelain Laminate Veneers of minimal thickness. Although minimal tooth reduction is a desirable goal, it is still generally acknowledged that at least some tooth surface reduction is required. However, unless enough tooth reduction is carried out by the clinician there may not be enough room for the technician to build adequate thickness of porcelain without producing over-contoured restorations for the clinician. This presentation will outline a simple and precise clinical technique to facilitate the minimal of tooth surface reduction while still allowing enough room for the technician to create aesthetic Porcelain Veneers without having to over-contour the restorations by building them outwards in a labial direction.

Learning outcomes:

At the end of the presentation delegates will:

  • appreciate the significance of adequate tooth preparation in allowing the technician to build correctly contoured and aesthetically pleasing porcelain restorations of minimal thickness
  • understand the benefits of following a strict protocol utilising a step by step approach when carrying out minimal preparation for porcelain laminate veneers
  • be able to select the correct dental bur to be used for each stage of the process, including the benefits of using calibrated depth cutting burs
  • be able to follow a systematic approach to minimal veneer preparation with confidence.

If the media are to be believed, many dentists prepare teeth for veneers far too aggressively. However, without a consistent approach to the process, the result may very well be an over prepared tooth.

As undergraduates, my generation were never actually taught a protocol to prepare teeth for crowns, let alone veneers, and we were often left to our own devices. In my day we were shown a diagram of a completed crown prep and then told to go away and do it. When all was finished we would call over our Instructors who would then critique the result (often condescendingly and with little positive to say, if my memory serves me!). Either way, not much was actually taught by way of a step by step approach of how we could achieve the finished preparation shape.

Over the years I have developed a protocol whereby the standard veneer preparation is broken down into 8 individual stages, with each stage being carried out using its own specific preparation bur. Each stage is undertaken one after another following a methodical step by step process in order to achieve very minimal tooth reduction, but at the same time providing enough clearance for the technicians to do their work. The “8 step prep” can be considered a “roadmap” to be used every time a veneer preparation is carried out, thereby fostering a consistent approach to tooth preparation. In times past my surgery looked like a bombsite with almost every piece of equipment in use, but now everything is under control and the atmosphere generally is much less stressed, to say nothing of keeping my surgery tidy …  your nurse will love you for it !

I feel this is a great “back to basics” presentation for anyone currently providing veneers in their practice, or equally for those who wish to provide veneers, but are perhaps less confident of how to approach “minimal preparation”
