Ivory Matrix Medium Molar 0.05mm - 12 pieces 4979/2 - Medesy (4979/2)

What is the Medesy medium 0.05mm ivory molar matrix?

The medium 0.05mm ivory molar matrix marketed by Medesy is a restoration instrument used in conservative dentistry. It comes in the form of a thin metal strip designed to surround the tooth during caries treatment or coronary reconstructions. Its structure is specifically adapted to molar dimensions, offering a medium height to cover the interproximal surface. This model is packaged in lots of 12 pieces under the reference 4979/2. As a dental metal matrix, it ensures physical separation between the cavity to be filled and the adjacent teeth, thus facilitating the creation of a rigorous anatomical contact point.

What are the clinical indications for this consumable?

The use of the ivory molar matrix is indicated for all direct restorations involving the proximal surfaces of molars (Class II cavities). It is particularly useful when using amalgams or composites to recreate the missing wall of the tooth. In conservative surgery, it allows for the confinement of the restoration material, prevents gingival overhangs, and guarantees satisfactory occlusal and proximal morphology. Its 0.05mm thickness facilitates its insertion into interdental spaces even when contact points are tight, making this device essential for complex posterior restoration treatments.

What are the technical characteristics of the 4979/2 matrix?

The Medesy 0.05mm ivory matrix features precise technical specifications to meet practitioner requirements. It has a thickness of 0.05mm, which corresponds to a standard 0.05mm dental matrix, offering a balance between resistance to deformation and flexibility for cervical adjustment. Its medium size is optimized for the morphology of permanent molars. Manufactured by Medesy S.r.l., this matrix is designed to be used with an Ivory-type matrix holder, allowing for effective tensioning around the tooth. The metallic material used guarantees stability during the packing of restoration materials.

What are the contraindications for the use of these matrices?

Although no specific medical contraindications are mentioned in the source data, the use of this dental metal matrix should be avoided in patients with a known hypersensitivity to the metals constituting the alloy, if specified by the manufacturer. Clinically, its use may be limited in cases of excessive coronary destruction that does not allow for stabilization of the matrix holder, or in the presence of severe gingival inflammation that risks causing bleeding that interferes with the polymerization of restoration materials. Reference should be made to the recommendations for use provided by Medesy S.r.l. for each specific clinical situation.

What are the precautions for use and handling?

As a consumable, the ivory molar matrix must be handled with care to avoid any deformation before positioning. The practitioner must ensure it is correctly adjusted at the tooth neck to prevent excess restoration material in the gingival sulcus. After filling, removal of the matrix must be done delicately to avoid fracturing the still-fresh restoration material, particularly at the marginal ridges. As with any thin metallic instrument, special attention must be paid during placement to avoid injuring the surrounding soft tissues (marginal gingiva and papillae).

Who is the manufacturer and what standards are respected?

The official manufacturer of this device is Medesy S.r.l., a recognized manufacturer in the field of dental and surgical instrumentation. The product is referenced under code 4979/2 within the Medesy catalog. Regarding regulatory standards, such as the medical device class or specific CE marking, this information is not detailed in the current technical documentation. Practitioners are invited to consult the product labeling and the instructions for use provided by Medesy S.r.l. to verify compliance with the regulatory requirements in force in their geographical area before any clinical use.
