The ceramic reverse three-quarter crown for anterior teeth: laboratory procedures

Area of Science:

• Dental materials science
• Prosthodontics
• Ceramic restorations

Background:

• The demand for esthetic and durable anterior dental restorations is significant.
• Porcelain restorations offer excellent biocompatibility and aesthetics.
• Developing efficient laboratory techniques for ceramic crowns is crucial for dental practices.

Purpose of the Study:

• To describe the laboratory procedures for fabricating a Hi-ceram porcelain anterior reserve three-quarter crown.
• To introduce a technique utilizing an aluminum oxide coping for enhanced crown fabrication.
• To assess the learnability and applicability of the described technique for experienced dental technicians.

Main Methods:

• A core of high-fusing aluminum oxide was utilized as a coping.
• Tooth contours were meticulously restored on the coping using a compatible porcelain material.
• Standard dental laboratory equipment was employed throughout the fabrication process.

Main Results:

• The described technique allows for the successful fabrication of anterior reserve three-quarter crowns.
• The use of an aluminum oxide coping provides a stable foundation for porcelain application.
• The procedure was found to be readily learnable by experienced ceramics technicians.

Conclusions:

• The Hi-ceram porcelain anterior reserve three-quarter crown technique is a viable option for dental laboratories.
• This method combines a robust coping with esthetic porcelain for effective anterior restorations.
• The technique's simplicity and reliance on standard equipment make it practical for widespread adoption.
