technique (teknēk´),

n 1. a skillful and detailed method of executing procedures to accomplish a desired result.
2. the method of performance of manipulation in any art; the terms
technique and
technic are used synonymously, but the word
technique pertains more to the artistic skill involved.

technique, aseptic,

n task performed in a sterile environment in order to avoid contact with harmful bacteria.

technique, bisection of the angle,

n an intraoral radiographic technique whereby an angle formed by the mean plane of the tooth and the mean plane of the film is bisected, and the central ray is directed through the tooth perpendicular to the bisection. This is the application of Cieszynski's rule of isometry. See also rule of isometry, Cieszynski's.

technique, calibrated angle,

n an intraoral radiographic technique using a specified degree in vertical angulation from the horizontal plane. It is a variation of the bisection of the angle technique and assumed to be the correct angulation for the majority of patients.

technique, chew-in,

n See chew-in technique.

technique, double investing,

n a method of investing wax patterns, whereby the pattern is covered with a primary layer of investment; this core is then invested, before or after the primary investment has set, in an outer, thinner mix of the same or a different type of investing material.

technique, dual impression,

n a technique by which the anatomic form of the teeth and immediately adjacent structures is recorded and by which the free-end denture foundation areas are registered in their functional form.

technique, Eames's,

n.pr in dental amalgam, a procedure using mercury and alloy in approximately a 1:1 ratio, thus not having residual mercury in the plastic mix.

technique, filling,

n the method used to obliterate the space in the root of the tooth once occupied by the dental pulp.

technique, Fones's,

n.pr See method, Fones's.

technique, Gow-Gates (GG) anesthetic,

n the injection of a local anesthetic that anesthetizes the mandible, along with the floor of the oral cavity, the anterior two-thirds of the tongue, the skin covering the zygomatic bone, and corresponding facial, buccal, and lingual tissues.

technique, hydroflow,

n See dentistry, washed-field.

technique, impression,

n a method and manner used in making a negative likeness. The series of operations or procedures used for making an impression.

technique, long cone,

n the use of an extended cone distance, generally 14 inches (35 cm) or more, in oral radiography. It is generally used with, but not confined to, parallel film placement.

technique metered spray,

n refers to a topical anesthetic dispersal technique that controls the amount and rate at which a drug is administered.

technique, Miller's radiographic localization,

n a method of identifying the buccolingual dimension of a tooth by taking a second radiographic image at an angle of 90° to the first. The technique is also useful for identifying the position of subgingival anomalies. Also called
right-angle technique; SLOB rule, which stands for same
lingual,
opposite
buccal. See also localization, radiographic; technique, parallel.

technique, parallel (right-angle technique),

n a technique in intraoral radiography in which the film is positioned parallel to the long axes of the teeth and the central ray is directed perpendicular to both the film and the teeth.

technique, periapical,

n any of several methods for placing radiographic film to capture images of tooth root structure.

technique, punch,

n a surgical incision of a circular area of soft tissue immediately above a submerged implant in order to expose the full diameter of the implant platform.

technique, scoop,

n office jargon for a one-handed method of needle recap and disposal in which the needle is used in an upward sweep to lift a safety cap onto the needle. The needle is then removed and discarded into a sharps container.

technique, short cone,

n the use of a short cone distance, usually 8 inches (20 cm) or less, that is supplied by the manufacturer as short cone. It is generally used with, but not confined to, the bisection of the angle technique.

technique, telephone,

n the friendly but businesslike conveying of ideas over the telephone.

technique, thermal expansion,

n a casting procedure whereby compensation is made for metal shrinkage by thermal expansion of the refractory investment mold.

technique, wax expansion,

n a casting procedure whereby compensation is made for metal shrinkage by thermal expansion of the wax pattern before setting of the investment.

free from infection or septic material; sterile.

aseptic fever

fever in the absence of infection, e.g. due to trauma, surgical manipulation of tissue, tissue necrosis, injection of certain chemicals, e.g. dinitrophenols.

aseptic necrosis of the femoral head

see legg-calvé-perthes disease.

aseptic technique

required for modern day veterinary surgery, especially orthopedic surgery. Includes a dust-free environment, complete immobilization of the patient, intensive skin preparation, capping, gowning, masking and gloving of the surgeon and assistants, draping and packing of the patient, proper equipment for removal of blood and other liquids and avoidance of the introduction of nonsterile items such as x-rays, stomach tubes, restraint gear into the sterile field.
