Without a doubt, dentistry as we know it will be facing huge change, post the coronavirus pandemic.

It's easy to get caught up in the hysteria:

• How will we financially recover?
• How will we manage with the inevitable influx of extensive treatment needed?
• How will we, with our patients, cope with navigating the new regulations for “soft-openings”?

As default as our nature may be to panic, now is NOT the time to do so - now is the time to take action.

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).

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. 

To identify your first One Visit Crown (OVC) case, look for;

The patient presented with cracked tooth syndrome on a lower premolar. The One Visit Crown (OVC) was chosen based on its competitive price and good aesthetics.

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.

Congratulations on taking the first step to delighting your patients with an affordable one visit dental crown solution.

To get the most out of the One Visit Crown system, it is important you receive clinical training to make sure that you are as comfortable as possible with the procedure.

The secret to a successful first OVC case is to be prepared.  

We've included in this post a checklist, plus extra tips so you can systematically plan your first OVC restoration and ensure everything goes as smoothly as possible.   

We've also included links where you can access further clinical training. 

Key resources we recommend you review before your first OVC case:

• Read the latest OVC Instructions 
• Download the OVC Chairside Guide for use during the procedure
• Review OVC case studies on our website 
• Watch the clinical run-through video in our videos section

This clinical tip will show you how to place the McDonald Matrix Band in three manageable steps. You will see how to stabilise the band while placing, which makes it easier to tighten the matrix band and to achieve the correct vertical height.
