Extraction techniques. Niemiec BA(1). Author information: (1)Southern California Veterinary Dental Specialties, San Diego, CA , USA. [email protected] A dental extraction is the removal of teeth from the dental alveolus (socket) in the alveolar bone. .. Rarely, tooth extraction was used as a method of torture, e.g. to obtain forced confessions. Until the early 20th century in Europe, dental. In dentistry, elevator instruments are used to luxate teeth, and this technique imparts forces to tooth particles that sever the periodontal ligament.

Luxation can also expand the space between teeth roots and the surrounding alveolar bone, by severing the periodontal ligament and tooth extraction techniques the roots away from the alveolar bone surface. This expansion increases the degrees of freedom of tooth particle movement inside the socket.

However, luxation forces on alveolar bone can potentially cause alveolar bone fracture, or cause necrosis of bone cells lining the socket, due to pressure-induced or compression-induced necrosis 456.

Forces on alveolar bone during luxation can be minimized by sectioning tooth particles such that individual tooth particles transmit less force to alveolar bone during luxation.

This article presents the elevator instrument techniques to luxate tooth particles, explains teeth sectioning and bone removal to optimize luxation effectiveness, and explains how the use of microscope-level magnification combined with shadow-free, head-mounted or co-axial illumination helps to optimize tooth particle luxation.

Elevator positioning An elevator should be positioned such that the ventral surface of the tip contacts a tooth extraction techniques point s on tooth extraction techniques tooth particle being extracted, while the dorsal surface of the elevator working end contacts a hard intra-oral point ssuch that if a tooth extraction techniques of a specific magnitude and direction is applied to the tooth particle at the ventral contact point of the elevator tip, the tooth particle will move progressively, but the force will not be enough to damage the ventral or dorsal contact point swhich would cause loss of leverage at that elevator position.

Alternatively, elevator positioning can be described as a combination of luxation parameters: If the tip contact points are structurally weak and can be damaged by a large force, or if a neighboring tooth must be used as a dorsal tip contact point, only a small force should be applied to the elevator tip contact surfaces that are available for luxating.

This non-ideal leverage may result in only a microscopic progressive movement of the tooth particle, which may only be detected with microscopes 9.

However, this microscopic movement can tooth extraction techniques to macroscopic movement of tooth extraction techniques tooth particle or permit microscopically deeper penetration of the elevator tooth extraction techniques between the tooth particle and the alveolar bone, which can open access to other elevator tip contact points and could cause additional microscopic progressive tooth particle movements.

Luxating while using a neighboring healthy tooth as a dorsal elevator tip contact area is generally discouraged 123. The clinician should try different elevator tip positions and angles to minimize movement of neighboring teeth.

The maxillary sinus sits tooth extraction techniques above the roots of maxillary molars and pre-molars. There is a bony floor of the tooth extraction techniques, dividing the tooth socket from the sinus itself.

This bone can range from thick to thin, from tooth to tooth, from patient to patient.

Dental extraction

In some cases tooth extraction techniques is absent and the root is, in fact, in the sinus. At other times, this bone may be removed with the tooth, or may be perforated during surgical extractions.

The doctor typically mentions this risk to patients, based on evaluation of radiographs showing the relationship of the tooth to the sinus. The sinus cavity is lined with tooth extraction techniques membrane called the Sniderian membrane, which may or may not be perforated.

Extraction techniques.

If this membrane is exposed after an extraction, but remains intact, a tooth extraction techniques exposed" has occurred. If the membrane is perforated, however, it is a "sinus communication".

These two conditions are treated differently.

In the tooth extraction techniques of a sinus communication, the dentist may decide to let it heal on its own, or, may tooth extraction techniques to surgically obtain primary closure—depending on the size of the exposure and the likelihood of the patient to heal.

In both cases, a resorbable material called "gelfoam" is typically placed in the extraction site to promote clotting and serve as a framework for granulation tissue to accumulate.

Patients are typically provided with prescriptions for antibiotics that cover sinus bacterial flora, decongestants, and careful instructions to follow during the healing period. This is primarily an issue with extraction of third tooth extraction techniques, but can occur with the extraction of any tooth should the nerve be close to the surgical site.

Two nerves are typically of concern, and are found in duplicate one left and one right: This nerve supplies sensation to the lower teeth on the right or left half of the dental arch, as well as sense tooth extraction techniques touch to the right or left half of the chin and lower lip.
