Restorations should reproduce the physiologic behavior of the natural tooth as far as possible, with biologic, biomechanic, functional, and esthetic integration.
3 Different treatment options may be considered when esthetic adhesive restorations in the anterior region are required: direct composite restorations, ceramic laminate veneers, and metal-free crowns (lithium disilicate, zirconia, alumina).
The choice between direct and indirect techniques should be based on several criteria: tooth vitality preservation, minimum loss of sound tissue, a minimally invasive approach toward the gingival complex, esthetic demands, patient age, financial cost, and total treatment time.
Further parameters are the number and extent of involved teeth, type of function, antagonist teeth situation, feasibility of functional and anatomical recovery of the restored tooth, and biomechanical resistance of the restored tooth.
Indirect techniques are indicated when treating multiple complex restorations, endodontically treated teeth with a major loss of sound tissue, complete crown fracture, major shape modifications, dental crowding, very young uncooperative patients, and patients with high esthetic demands,discoloration that is resistant to vital bleaching procedures; displeasing shapes or contours and/or lack of size and/or volume, requiring morphologic modifications; diastema closure; minor tooth alignment, restoring localized enamel malformations; fluorosis with enamel mottling; teeth with minor chipping and fractures; and misshapen teeth
Among indirect techniques, ceramic laminate veneers represent a well-documented, effective, and predictable treatment option.
In dentistry, a veneer is a thin layer of dental restorative material usually porcelain that replaces enamel.
Based on their strength, longevity, conservative nature, biocompatibility, and aesthetics, veneers have been considered one of the most viable treatment modalities.
Aesthetic veneers in ceramic materials demonstrate excellent clinical performance and, as materials and techniques have evolved, veneers have become one of the most predictable, most aesthetic, and least invasive modalities of treatment. For this reason.
Porcelain veneers are an excellent solution for correcting small or medium spaces between teeth, imperfections in tooth position (e.g., slight rotations), poor color, poor shape or contours, as well as some minor occlusal (bite) related problems. Porcelain veneers can allow for dramatic improvements for patients who have worn their teeth by bruxism (grinding of one’s teeth through habit patterns) or fractured teeth.
Several ceramic materials are currently indicated for veneers: lithium disilicate, feldspathic ceramic, feldspathic reinforced with leucite, fluorapatite, and lithium silicate reinforced with zirconia.
Thus, translucent zirconia has been considered as an esthetic material, as it offers indications for manufacturing crowns and anterior and posterior monolithic fixed prostheses, including veneers and ultrathin veneers.
E.max lithium disilicate has a wide spectrum of indications, and it is characterized by good modeling properties, high stability and excellent firing behavior. It is suitable for many types of restorations in the anterior and posterior region. Due to its natural-looking tooth coloring and excellent light-optical properties, this material produces impressive results.
Direct composite veneers serve as one method for restoring anterior teeth.
The reasons for choosing this treatment are: correction for esthetic concerns, attrition and erosion, abfraction, fractures, caries, diastemas, restoring proximal contact, occlusal discrepancies, the desire for a minimally invasive approach, and the financial limitations of the patient.
Also of significant benefit is their use in medically compromised patients who display dental anomalies as secondary signs of conditions such as fluorosis and amelogenesis imperfecta.
The long-term maintenance of the surface quality of materials is fundamental to improving the longevity of esthetic restorations.
The contraindications must be recognized as well. The placement of veneers is contraindicated when there is reduced interocclusal distance; deep vertical overlap anteriorly, without horizontal overlap; or severe bruxism or parafunctional activity. Severely malpositioned teeth, the presence of soft tissue disease, and teeth with extensive existing restorations are other factors that prevent the placement of laminate veneers.
The maintenance of your porcelain laminate veneers is relatively simple. Here are some recommendations:
