Direct bonded glass ionomer crowns.

Area of Science:

• Restorative Dentistry
• Dental Materials Science

Background:

• Severely carious incisors pose a restorative challenge.
• Direct bond crowns offer a conservative approach to tooth restoration.
• Glass ionomer cements are bioactive restorative materials.

Observation:

• One-year clinical evaluation of direct bond crowns fabricated with glass ionomer filling materials.
• Assessment of crown retention, wear, and esthetics.
• Clinical performance in restoring incisor teeth.

Findings:

• The direct bond crowns exhibited favorable wear characteristics after one year.
• Excellent crown retention was observed in all cases.
• Esthetic outcomes remained highly satisfactory post-treatment.

Implications:

• Glass ionomer materials demonstrate significant potential for restoring severely decayed incisors.
• Direct bond crown technique with glass ionomers offers a viable and durable restorative option.
• Further long-term studies are warranted to confirm durability.
