Kobra simulator? 手術(shù)虛擬模擬訓(xùn)練 FORSSLUND SYSTEMS
FORSSLUND SYSTEMS AB, proudly presents a one of a kind high fidelity simulator designed for teaching Oral Surgery procedures using Virtual Reality.
KOBRA consists of state-of-the-art haptic technology and 3D stereoscopic viewing, paired with a flexible system of adding new patient cases that is customised to your needs.
A custom-made haptic device lets you feel interacting forces when drilling or exploring the virtual patient’s anatomy.?
Various tissues such as Bone, Enamel and Dentin can be represented by different degrees of hardness.?
With the included 3D glasses, students can simultaneously view the virtual patient in full-screen on the Large 3D Monitor
Get new patient cases and exercises as they are developed, and store recorded sessions in the cloud.
There are a growing number of patient cases available for the KOBRA simulator and new ones can be created on demand.
The core simulation engine is open source, meaning you can have it customised or extended by third-party developers.
The KOBRA simulator is in use at the Dental schools of two leading European universities and has been the subject of studies in Sweden at The Karolinska Institute and The Royal Institute of Technology.
1. CrossBox
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
?
Patient
A 28-year-old male who requires surgical extraction of his third molar.
Treatment plan
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.
Suggested solution
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
side.
3. Impacted d23
?
Patient
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.
Treatment plan
Impacted d23 extraction with osteotomy and tooth sectioning.
Suggested solution
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
?
Patient
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.
Treatment plan
Tooth 36 extraction with root separation.
Suggested solution
Section the crown down to the root separation. Remove some bone if necessary. Apply
the elevator to each tooth half.
5. Impacted d85
Patient
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.
Treatment plan
1) Impacted d85 extraction with osteotomy and tooth sectioning. 2) D47 extraction with
osteotomy and tooth sectioning.
Suggested solution
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
Patient
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.
Treatment plan
Tooth 22 apicoectomy.
Suggested solution
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.
