Treatment and Care

The treatment phase for dental crowns at Liv Hospital is a meticulously orchestrated clinical procedure that blends microsurgical precision with advanced prosthodontic engineering. The workflow is designed to maximize the biological preservation of the tooth while ensuring the mechanical durability of the restoration. From the initial anesthesia to the final cementation using advanced dental glue for a crown (luting agents), every step is governed by strict protocols. We utilize CAD/CAM technology to streamline the dental crown procedure, often reducing turnaround times while increasing accuracy. Whether it is a routine restoration or a complex dental implant crown, our focus is on patient comfort and long-term survival of the prosthesis.

The Clinical Procedure: Step by Step

DENTISTRY

The standard protocol typically involves two visits, though same-day options exist.

Visit 1: Preparation and Temporization

  • Anesthesia: Profound local anesthesia is administered. For anxious patients, sedation options are available.
  • Core Buildup: If the tooth is severely damaged, a composite resin core is bonded to the remaining structure to create a solid foundation for the crown.
  • Tooth Preparation: The dentist reduces the circumference and height of the tooth by approximately 1-2mm. The preparation geometry is critical; it must have a specific taper (6 degrees) to ensure retention. The margin geometry (chamfer or shoulder) is tailored to the chosen dental crown material zirconia or ceramic, to provide a perfect seal.
  • Tissue Management: Retraction cords or lasers are used to gently retract the gums, exposing the preparation margin for an accurate impression.
  • Impression/Scanning: A digital intraoral scan is taken. This captures the preparation, the adjacent teeth, and the bite registration.
  • Provisionalization: A temporary acrylic crown is fabricated and cemented with temporary cement. This protects the sensitive dentin, maintains the tooth position, and preserves the gum architecture while the permanent crown is made.

Laboratory Fabrication (CAD/CAM)

The digital file is sent to the lab (or milled chairside).

  • Design: Technicians design the crown on a computer, optimizing contact points and occlusion.
  • Milling and Sintering: The crown is milled from a zirconia or ceramic block. Zirconia is then sintered in a furnace at high temperatures to achieve its final hardness and strength.
  • Glazing and Polishing: The surface is stained and glazed to mimic natural enamel characteristics.

Visit 2: Delivery and Cementation

  • Try-In: The temporary crown is removed, and the permanent crown is seated. The fit is verified clinically and radiographically.
  • Adjustments: The contact points and occlusion (bite) are checked with articulating paper and adjusted to ensure no interference.
  • Surface Treatment: The internal surface of the crown is treated (sandblasted or etched) to enhance bonding.
  • Cementation: A definitive dental cement for crown retention (resin-modified glass ionomer or resin cement) is applied. The crown is seated under pressure. Excess cement is meticulously removed to prevent peri-implant or gingival inflammation.
  • Light Curing: If resin cement is used, a curing light initiates the setting reaction.

Variations in Treatment

DENTISTRY
  • Dental Implant Crown: The procedure involves taking an impression of the implant fixture. The crown is then either screwed directly into the implant or cemented onto a custom abutment. The focus here is on the emergence profile to shape the soft tissue.
  • Pediatric Dental Crowns: For children, pre-fabricated stainless steel crowns are often crimped and cemented in a single visit to protect decaying primary teeth until they exfoliate naturally.
  • Same-Day Crowns (CEREC): Utilizing chairside milling units, the entire process from preparation to cementation can be completed in a single appointment, eliminating the need for a temporary crown.

Post Treatment Care and Management

  • Loose Crown: If a crown debonds, it must be re-cemented immediately. Patients should not rely on over-the-counter dental glue for a crown as a permanent solution; these are temporary measures.
  • High Bite: If the tooth feels “high” or hits first, the patient must return for adjustment to prevent bruising of the ligament or pulpitis.

Advantages vs. Disadvantages

We ensure patients understand the trade-offs.

  • Advantages: Restoration of form, protection of weak structure, esthetic improvement, and high success rate.
  • Disadvantages of Dental Crowns: Irreversible removal of tooth structure, potential for pulp irritation leading to root canal therapy, cost (dental crowns cost is higher than fillings), and the eventual need for replacement.

Material Specific Care

  • Zirconia: Highly durable but requires polishing if adjusted to prevent wear on opposing teeth.
  • Glass Ceramic: Requires careful bonding protocols and is more brittle than zirconia, so avoid extreme forces.

FREQUENTLY ASKED QUESTIONS

Why does my tooth hurt after getting a crown?

Mild sensitivity to hot and cold is normal for a few weeks as the tooth nerve heals from the preparation; however, severe or throbbing pain may indicate the need for a root canal.

A loose crown usually means the cement seal has broken; you should see your dentist immediately to have it re-cemented before bacteria cause decay underneath.

This is often the metal edge of a porcelain-fused-to-metal crown showing due to gum recession; replacing it with an all-ceramic or zirconia crown can eliminate this line.

Yes, if the crown margin is rough, overhangs, or invades the biological width of the gum attachment, it can cause chronic inflammation and bleeding.

No, a crown should fit perfectly into your bite; if it feels high or you hit it first when closing, you need a quick adjustment to prevent pain and damage.
