It is an instrument that in the form of a forceps and acting as a 2nd degree lever, picks up the tooth and through different movements that break the tooth socket ligament eject the piece from its socket.
Like most dental instruments it consists of 3 parts:
- Handle: Handles are usually of different sizes to be comfortable and to release enough pressure to remove the required tooth.
- Hinge: The hinge is only a connection mechanism between the handle and the spout.
- Peak: The peaks of the extraction forceps are the origin of a wonderful variation between them. The beak is designed to adapt the root of the tooth to the crown-root junction. It is important to remember that the tips of the forceps are designed to be adapted to the structure of the tooth root and not to the crown of the tooth. In a different sense the spikes are designed for 1, 2 or 3 roots.
Types of forceps
- Forceps for the upper jaw: In the upper jaw the forceps for the anterior group are straight, and for the premolars and molars the active part forms an angle of 30º to 45º with the handle.
- Jaw forceps:In the lower jaw, the active part and the handle form a 90º angle.
- Upper incisor forceps:They are straight, the tips do not touch and when the tips are in contact they are used to extract root remains from the anterior area.
- Upper premolarforceps : The upper premolar forceps are the same but with an inclination of the active part in order to better grasp the tooth, since the active part must always be parallel to the tooth axis.
- Upper molarforceps : The upper molar forceps have different blades, the blade that takes the tooth from the vestibular face presents a beak whose purpose is to enter the vestibular roots of the upper molars. There are different designs of this type of forceps. The palatal palate is rounded so that it takes up the entire palatal root. Upper molar forceps.
- Forceps for upper third molars:For the third upper molars we use an equal bladed forceps, it has a very marked angulation so it adapts perfectly to the axis of the molar. It can also be used for the other molars.
- Bayonet for superior roots:For root remains in the superior arch we use straight forceps with the tips joined in the anterior segment and the bayonet-shaped forceps for more posterior roots.
- Forceps for lower incisors and premolars:Forceps for lower roots
- Anterior prey forceps (frontal attack)
- Physick Forceps Exists:A little used forceps called Physick, which rests on the anterior molar and dislocates the molar that we are going to extract, taking it only on the mesial side. It is a dangerous forceps, which can also be used in the jaw, and can cause a fracture of the maxillary tuberosity by exerting excessive distal force.
