Dental impressions are primary as they are taken to ensure that the new bridge or crown which needs to be made would align perfectly with the current bite. Dentist Barrie uses mould formed by these dental impressions which are similar to the teeth so that the treatment has a natural feeling and doesn’t affect the soft tissues.
How are dental impressions taken?
Discomfort during dental impressions procedure is inevitable as this is the only way to make sure that the results are perfect. This discomfort is due to the alginate materials which are used or a gag reflex. The alginate materials don’t have a pleasant taste, as they are a foreign entity entering the body they might trigger the defence mechanism of the body causing you to have a gag reflex.
In order to take dental impressions, the dentist begins by picking out a horseshoe tray that would approximately fit the patient’s teeth. This tray has been filled either with alginate or polyvinyl siloxane. It is crucial to remember that these products used in the procedure should not be swallowed even though they are non-toxic. After being filled up, the tray is then placed into the patient’s mouth and left to stand for five minutes. You are advised to stay still during these five minutes as any movement could lead to inaccuracies. After the tray is removed it is used to cast the bridge or crown.
What to do when gagging occurs?
Gagging is normal during a dental impression. If gagging does occur then try to breathe through your nose. At this point breathing through your nose when your mouth is wide open might be a little difficult, but it would help to get a perfect impression. Before the procedure, you could consider taking some decongesting medication if your nose is congested. In the meanwhile, allow your saliva to drool.
Try and distract yourself during the process. You could do some calculations, count sheep, plan your daily activities or think about things or read the charts in the dental room. Make sure that you are comfortably seated before the tray placed in your mouth. Movement after the tray has been placed can hamper the procedure. You might be set into an upright position or asked to tilt your head forward in order to ensure that the impression material doesn’t trickle down your throat.
What are 3D scanners?
The results from traditional methods might have some slight variations. Impressions taken by 3D scanners are faster, more comfortable and accurate. The scanner is inserted into the mouth and scans through the teeth with a laser. The time estimate depends upon how far each tooth is. The whole process takes very little time. The data is transferred to the computer to form an accurate 3D model. This model can be printed out if needed.
