Abstract
The invention discloses a developing composition for gum, which relates to the technical field of dentistry and consists of light-cured gum barrier resin and iohexol injection.
Description
Technical Field
The invention relates to the technical field of dentistry, in particular to a developing composition for gingiva.
Background
The gingival biotype is used to describe the morphological characteristics of the tooth body, the soft tissue of the gum and the alveolar bone influenced by gene and environmental factors, and the gingival thickness, width and crown morphology together determine the classification of the gingival biotype. For the biological type of the thin gingiva, the gingiva has the risk of recession, and the aesthetic effect of late planting and conventional crown repair is influenced; for the thick gum biotype, deep periodontal pockets are easily formed. Therefore, the preoperative objective and accurate measurement of the thickness and width of the gum is beneficial to the later clinical curative effect.
Gum thickness is one of the most important criteria for gum biotype classification. The measurement methods for the gum biotype mainly comprise (1) a direct puncture method: measurements are taken under local anesthesia by penetrating the gingiva perpendicular to the bone plane with an instrument such as a unc-15 probe or an enlargement file, which is simple but traumatic. (2) Avansen gauge method: after flap surgery, the gingival flap can be clamped by an Avenson measuring instrument for measurement, and the method has high precision, but patients generally do not accept the method. (3) Ultrasonic measurement: the method is quick and accurate, but high in cost and high in operation requirement accuracy, and a transmitter of an ultrasonic instrument is placed on the surface of the wet gum, and the thickness of the gum can be measured after 2-3 s. (4) Periodontal probe gingival sulcus fluoroscopy: the periodontal probe is inserted into the gingival sulcus, and if the periodontal probe is of a thin gingival biological type, the contour shape of the periodontal probe below the gingiva can be seen through the gingiva; the probe profile is thick gum biotype if not visible. (5) Cone beam CT method: the digital oral cavity is the trend of the future oral treatment development, the CBCT method has the advantages of flexible scanning range, high image precision, short scanning time, low radiation and better soft tissue imaging effect, but artifacts of labial soft tissue, crown prosthesis and metal filler can interfere with imaging and can not clearly and effectively display the gum surface.
The cornified gum is the basis of periodontal health, plays an important role in aesthetic aspect, and is also an important anatomical basis for implementing various periodontal operations, such as pre-operative examination of crown lengthening operation, membrane gum operation and the like, the cornified gum width of an operation tooth and an adjacent tooth needs to be measured, on one hand, the cornified gum can be combined with other clinical indexes to guide the design of a soft tissue operation incision, on the other hand, the cornified gum can be used for predicting and judging the operation prognosis risk, and the necessity of judging the cornified gum transplantation and the like in advance. The current main methods for clinically measuring the width of the keratinized gingiva are as follows: the distance between the gingival margin closest to the coronal aspect and the membrane-gingival junction is measured at the midline of the labial surface of the tooth, which is simple to operate, but less accurate and susceptible to alveolar bone anatomy.
Therefore, the patent provides a more convenient, safe, noninvasive and accurate developing composition for gingiva, and the thickness and the width of the gingiva can be accurately measured by combining CBCT.
