The purpose of this exercise is to remove the yellow cross without damaging the blue background. The goal is for you to get acquainted with the simulator and how the drill behaves, as well as to practise the steady handling of a dental drill. The blue material is hard, representing enamel, and the yellow represents dentin. This can be used to guide the drill moving close to the wall.
2. Mesioangular retinated third molar
A 28-year-old male who requires surgical extraction of his third molar.
The goal of this exercise is to fully remove the third molar in a safe manner. Take a look at the X-ray
image and plan accordingly.
Remove some bone to get better access. You can try to pry the tooth loose with the elevator
(press right pedal), but the crown needs to be removed for you to get the tooth out. Section the tooth
in the enamel-dentin border about 2/3 through the tooth. Apply the elevator, and if you have
drilled enough, the crown will come out. Now try to pry out the root with the elevator; you may
need to remove some additional bone to get it out. When completed, you can inspect the
result by hiding the face (using the pad). Tip: rotate the model to inspect from the lingual
3. Impacted d23
Girl, 15 years old, seeks medical assistance due to complaints about a missing d23 and a cross bite
on the left side. After examination, an iCAT is made and a diagnosis made of an impacted d23 in the horizontal plane on the palatal side and root resorption of d21.
Impacted d23 extraction with osteotomy and tooth sectioning.
In this procedure it is important not to harm the surrounding teeth. Remove bone by the border
of the enamel and dentin of the impacted tooth. Section the tooth at this location. Remove
the crown and then the root using the elevator. Examine the remaining hole with the elevator.
4. Extraction d36
Woman, 25 years old, seeks medical assistance due to complaints about d36. This tooth
bothers the patient periodically on the bite. Objectively, d36 is stable, probably ankylosed, and slightly sensitive to percussion.
Tooth 36 extraction with root separation.
Section the crown down to the root separation. Remove some bone if necessary. Apply
the elevator to each tooth half.
5. Impacted d85
Girl, 16 years old, seeks medical assistance due to complaints about a missing d45 and
d46. After examination, an iCAT was made and diagnosed impacted d85 (probably ankylosed) and impacted d45 and d46.
1) Impacted d85 extraction with osteotomy and tooth sectioning. 2) D47 extraction with
osteotomy and tooth sectioning.
Begin by removing bone to access the impacted d85, then section it vertically and, if needed,
horizontally. Remove each part of the tooth using the elevator. Section the d47 from the
crown and down between the roots. Pry out each part with the elevator.
6. Apicoectomy d22
Woman, 37 years old, seeks medical assistance due to complaints about d22. This tooth
bothers the patient periodically on the bite. Objectively, d22 is stable, slightly sensitive to
percussion, with qualitative endodontic treatment.
Tooth 22 apicoectomy.
Access the apex of the root by removing bone. Use the excavator (right pedal) to remove the
infected tissue. Make sure to feel around the cavity to remove it all.
Currently we have three new cases in the making and eventually there will be more, but we need your help. By buying a simulator or applying for grants for creating cases for your curriculum, you will support the creation of a growing library of cases.
