How to perform effective indirect restoration of front teeth
Straight composite veneers quickly lose their luster, absorb food coloring and shrink, disrupting the edge fit. Degradation of the polymer matrix leads to micro-flow and the development of secondary caries on the contact surfaces of the incisors.
Indirect restoration using lithium disilicate ceramic linings ensures color stability and anatomical accuracy. The protocol requires careful planning using digital casts and wax modeling of a future smile.
Planning and aesthetic analysis
The restoration of the smile zone begins with a photo puncture and taking impressions with A-class silicone masses. A dental technician creates a Wax-up project by transferring an anatomical shape to a plaster model of the patient's jaw.
- assessment of the symmetry of the zenith of the gum;
- calculation of proportions of height and width of incisors;
- determination of the inclination of the axes of the teeth relative to the median line.
The project is transferred to the oral cavity using double-curing plastic, a mock-up procedure. The patient evaluates the phonetics and aesthetics of future veneers before starting enamel preparation.
Gentle preparation and isolation
Ceramic dental treatment is carried out with optical magnification within the enamel layer, the maximum grinding depth is 0.5 mm. Preservation of the enamel frame ensures reliable adhesion of the final structure.
- gum retraction with thin threads;
- removal of a working digital scan by an intraoral scanner;
- fixing of temporary pads made of bisacrylic plastic.
The edges of the preparation are brought out in the form of a groove, which gives a smooth transition of ceramics into the root tissue. The absence of sharp corners of the stump reduces internal stress in pressed glass ceramics of the E.max brand.
Adhesive fixation protocol
The integration of the veneer with the tooth tissues is carried out in conditions of absolute dryness of the working area. The installation of a latex handkerchief - cofferdam - eliminates the ingress of saliva and gum fluid onto the etched surface of the enamel.
The inside of the ceramic is treated with hydrofluoric acid and coated with silane to create a chemical bond with the fixing cement. Polymerization of the composite material under the influence of a powerful LED lamp forms a monolithic structure resistant to chewing loads.
