Description

Technical Field

[0001] The utility model belongs to the technical field of oral medical instruments, and in particular relates to a forming sheet capable of extending the depth. Background Art

[0002] When there is a subgingival defect distal to the mandibular second molar, crown lengthening, orthodontic traction, and gingival wall lifting can be used clinically to obtain good interproximal margins. Each of the three has its own advantages and disadvantages.

[0003] Crown lengthening is a technique that exposes the clinical crown height by appropriately removing gingival tissue and alveolar bone through surgical methods in accordance with the principle of periodontal biological width. This technique requires reducing the height of the periodontal supporting bone, has a long treatment period, and its clinical efficacy is easily affected by technical factors, root treatment, and anatomical factors of the affected tooth. Orthodontic traction is used to expose the gingival wall of the tooth defect, and the clinical operation time is also long. Its feasibility and clinical effect are affected by multiple factors such as the crown-root ratio, root shape, root bifurcation characteristics, and tooth position.

[0004] Gingival wall lifting is a technique that uses adhesive restorative materials to raise the cervical margin during indirect restoration, promotes the separation and molding of the indirect restoration, facilitates the placement and isolation of the rubber dam system, and improves the bonding effect of the adhesive cement. This technique has the advantages of being minimally invasive, highly efficient, and easy for later restoration. It is suitable for localized defects that do not violate the biological width, and for cases where the buccal and lingual walls of the remaining tooth are sufficient to set up a molding sheet, and ensure that the molding sheet fits tightly against the defect edge and the rubber dam can effectively isolate the defect edge. Currently, there is no unified and standardized design principle and clinical operation process for reference for this technology.

[0005] Clinically, some Class II cavities with particularly deep proximal defects require gingival wall lifting, but conventional molding sheets on the market cannot penetrate deep into the root of the gingival wall. Currently, there is a lack of molding sheets that can extend the depth to achieve tight filling of deep Class II cavities in the gingival wall.

[0006] Therefore, a new technology is needed to solve the problem of lacking a forming sheet with extended depth in the prior art. Utility Model Content
