In this post, we will explain how to achieve correct occlusal distance with the One Visit Crown (OVC)
Tooth preparation - how much clearance to leave
When preparing the tooth for the placement of the One Visit Crown, at least 1mm of clearance needs to be allowed in the central fossa and 1.5mm at the cusps and marginal ridges for the OVC to be seated.
See how to use the OVC Wedges for deep margin elevation prior to placement of the McDonald Matrix Band.
The OVC Wedges are anatomically shaped to follow the natural curve of the tooth. They come in both a left and right version for mesial or distal placement, and are an ideal tool for deep margin elevation (DME).
Many dentists have questions about how much to prep the tooth prior to placing the OVC 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 OVC 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 (OVC). 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 OVC
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 OVC 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.
Congratulations on taking the first step to delighting your patients with an affordable one visit dental crown solution.
