Magnetic resonance imaging of TMJ

Magnetic resonance imaging (MRI) of my Temporomandibular joint.

After to remove my wisdom teeth I started having jaw pain and articular problems. Now, 2 years later more or less, I did a MRI. Is a diagnostic prove that shows soft tissues. 

Left side: Seems good, just a small dislocation. 





Right side: displacement of the disc


If we take a look at the right side: the red circle shows the disc. We can see a displacement of the disc without reuptake. If it was good the disc will be in the glenoid fossa. 





In the coronal section we can see that if we go forward, the disc is going to be before the fossa not with the condile.

CASE 4563.2

Yesterday at the university clinic, a patient came for a cleaning. He said he had no apparently disease and that he also brushes his teeth once a day.
He has a severe gingivitis generalised. In the first visit this patient was bleeding all the time so the probing was very difficult. He has a lot of calculus under his gums that apparently we can not see only deduce because his gums are red, shining and big.
We tried to discover why, brushing his teeth once a day, he had this gingivitis. In one moment he said that he spent 2 years in prison and that's why he couldn't brush his teeth well. He lived under pressure.  

Here is the case before we started: 




Here is the end:




Now we need to visit him next time to see if his gums disminued with the cleaning and the products that we gave to him:

Pediatric Crown

Pediatric Crown are the best durable restoration and successful in primary dentition with decays or fractures. It doesn't break and rarely wears in the few years remaining in the mouth. It remains attached to the tooth until the exfoliation and you always have to inform the parents about this fact.

It is indicated in this cases:
  • Restoration of cavities in two or more surfaces
  • Children with high risk of cavities
  • After receiving a pulp treatment: pulpotomy or pulpectomy. 
  • Teeth with structural defects
  • Restoration in fractured teeth or fractured cusps
  • Used like a space maintainer and teeth with excessive wear.
In this image we can see the crowns with the mainteiner.
 

It is contraindicated when the teeth is going to be exfoliated in less than 6-12 months. 

They provide us with this metallic crown:




We first have to isolate the teeth and then we start milling:

Hawley retainer

In this new post I want to show what we did in class of orthodontics: Hawley Retainer. It is a removal brace used to keep teeth straight after fixed braces is removed. It is made by resin and stainless steel wire.

                 

This is a Angle plier that has two ways to fold the stainless: right angle (right side of the picture) or round (left side in the picture). 
After an hour I finally folded my stainless as I could.
