A porcelain crown is a custom-fitted cap that covers a tooth weakened by extensive decay, fractures, or structural defects. It is a permanent restoration designed to protect the tooth while fully regaining its aesthetic appearance and chewing function.
Treatment Processes:
Precision Preparation: The tooth is reshaped at a micrometric level to create space for the crown's placement.
Digital Optical Impression: The prepared form is transferred to a digital platform as error-free data using laser scanners (Intraoral Scanners) instead of traditional pastes.
CAD/CAM Design: Computer-aided design software is used to create a crown form that best matches the morphology of adjacent teeth and the patient's smile line.
Ceramic Block Milling: The designed form is processed from a block of reinforced porcelain in high-tech milling machines without manual intervention.
Adhesive Cementation: The prepared crown is molecularly bonded to the tooth using specialized light-cured resin cements, concluding the process after functional testing.
Benefits and Advantages:
Biocompatible Aesthetics: Being metal-free, it avoids allergic reactions or gray reflections on the gums, providing a maximum "natural tooth" feel.
Superior Light Translucency: It reflects and refracts light just like natural enamel, preventing the restoration from appearing dull or artificial.
Wear Resistance: The smooth surface of porcelain minimizes plaque accumulation and resists staining from external factors like coffee or tea.
Structural Protection: It prevents fractures in weakened or root-canal-treated teeth, extending the functional lifespan of the tooth.
