Now, these are important in helping to retract the cheek and tongue when there are treatments happening. This will also help with wrist position in the dentist as well, since it’ll give your fingers the properly resting place to help reduce the strain on the dentists’ hand. A fulcrum will give you the correct amounts of pressure when each stroke is used.
There are various types of finger rests for you to choose from as a dentist. For a patient, you might notice a few of these when they are being used, and we’ll go over them.
There is first the conventional, which is where the finger rest is on the surfaces that are next to the area being worked. Then there is the cross arch, which I on the other side of the arch being worked on. Then there is the opposite arch, which is on the surfaces opposite on the arches that are being worked on. There is also the finger n finger, which is where you use the fourth finger of your hand is on the index finger of the non-operating hand which is typically on the lingual surfaces of the posterior teeth when they are being worked on. There is also the palm up extra oral fulcrum, which is on the backs of the fingers, which is on the lateral aspect of the mandible while the maxillary teeth are being worked on. finally, there is the palm down, which is where the front of the fingers is on that same area while the maxillary teeth are being worked on.
You might also notice that there is a fulcrum placement as well. There are three types. The intra-oral, which is where the ring finger is on a tooth close to the working area, extraoral, which is where they’re on the chin or cheek to help stabilize, and then the advanced fulcrum, which is a variation of both of these where more advanced hand placements are made to help stabilize the wrist and finger position.
You might notice that the wrist is aligned with the lower arm, the palm is opened and relaxed to help decrease strain, the pressure is light against the handle with the thumb in a good grip, and the index finger and thumb are held in almost a rounded shape against the instrument of choice. If you notice these, then you’ll be in good hands, since the dentist is making sure that their wrists are being taken care of.
If you use the right technique, along with the finger rests and the fulcrums, you’ll be able to have a stress-free position, and it’ll allow you as a dentist, and you as a patient to have a better experience.
If you notice that your dentist looks strained, you can even ask your dentist at Eagle Rock about this, and they might tell you. you can learn more about it from them, but if you notice the dentist is using a strange placement of fingers for everything, know that it is because they are trying to protect their hands, to make sure that they work great, for the dental procedures.
