Many dentists have questions about how much to prep the tooth prior to placing the OVC3 One Visit Crown. If you haven't already, make sure you read this blog post on how to achieve correct occlusal distance when placing the One Visit Crown. One of the benefits of the OVC3 is that is doesn't need an invasive circumferential prep so is more conservative for the tooth.
In this series of blog posts we will be addressing some of the most frequently asked questions surrounding the One Visit Crown (OVC3). Nothing in dentistry is easy, but we hope that some of these tips and tricks will help you to continue to provide great clinical outcomes for your patients.
Firstly, make sure that you have read our articles on how to achieve tight contacts:
- How to get tight contacts using the Garrison Composi-Tight Original Ring
- How to get consistently tight contacts with the OVC3 direct technique
If you familiarise yourself well with the above methods to get tight contacts, then ideally you should not end up with an open contact at all. However, on the odd chance that it does occur, below we will outline what to do in order to recover.
The OVC3 system is flexible in its use. To create separation, you can use any of the following;
- Garrison Composi-Tight® original ring with wooden wedges
- Wooden wedges alone
- Stretch Wedges
Below we will show you a clinical tip on how to use wooden wedges in combination with a separating ring for optimum separating force.

This case study depicts a slightly different technique used by Dr Terry Wong, whereby the uncured material on the buccal side is shaped with OptraSculpt Pads (Ivoclar Vivadent) prior to curing. Dr Wong prefers to do as much of the shaping as possible prior to the final cure to reduce the time needed for finishing and polishing afterwards.
Dr Terry Wong B.SC (HONS) MELB, B.D.SC (MELB) is a leading dentist from Melbourne, Australia.

Every clinician has their preference over which method they like to use to complete a One Visit Crown. Some of you will prefer the direct method for the speed of the procedure and the direct bonding benefits, others will prefer the semi-indirect method for the ease of access and ability to more easily correct any errors along the way. Both of these methods are great techniques that use the McDonald Matrix Band.
