New Single-bottle Ceramic Primer: 6-month Case Report and Laboratory Performance

Area of Science:

• Dental Materials Science
• Adhesive Dentistry
• Biomaterials

Background:

• A novel self-etching glass-ceramic bonding agent, Monobond Etch and Prime (MEP), combines acid conditioning and silanes in a single bottle.
• This simplifies the bonding procedure for lithium disilicate (LD) restorations, reducing steps and chair time.
• A case report evaluated its 6-month clinical performance and in vitro bond strength compared to traditional hydrofluoric acid (HF) etching.

Observation:

• A 42-year-old female patient received esthetic treatment including LD crowns and veneers.
• After 6 months, no marginal defects such as staining, gaps, or fractures were observed.
• In vitro testing showed microshear bond strength to LD was statistically similar between MEP and HF conditioning.

Findings:

• The self-etching glass-ceramic bonding agent (MEP) exhibited favorable in vitro bond strength to lithium disilicate.
• Clinical follow-up at 6 months revealed no adverse effects or marginal deterioration.
• MEP demonstrated comparable bond strength to conventional hydrofluoric acid etching.

Implications:

• The new self-etching bonding agent offers a simplified, efficient alternative for esthetic dental bonding procedures.
• It shows promise for reliable bonding of lithium disilicate restorations.
• Further long-term clinical studies are recommended to validate its performance.
