Bonded amalgam restorations: current research and clinical procedure

Area of Science:

• Dental Materials Science
• Restorative Dentistry

Background:

• Amalgam bonding has evolved significantly over time.
• Understanding its historical development is crucial for current applications.

Purpose of the Study:

• To review the history of amalgam bonding.
• To compare clinical and laboratory findings on amalgam bonding efficacy.
• To provide guidelines for conservative preparation and clinical procedures.

Main Methods:

• Literature review of historical developments in amalgam bonding.
• Comparative analysis of recent clinical studies and laboratory results.
• Synthesis of conservative preparation guidelines.
• Description of a step-by-step clinical procedure for amalgam bonding.

Main Results:

• Clinical studies corroborate laboratory findings, showing reduced microleakage with amalgam bonding.
• Amalgam bonding demonstrates increased material retention and inhibition of secondary caries.
• Evidence suggests reinforcement of tooth structure and reduced cuspal deflection when using amalgam bonding techniques.

Conclusions:

• Amalgam bonding is a viable technique with documented clinical benefits.
• Conservative preparation guidelines enhance the effectiveness of amalgam bonding.
• The reviewed procedures offer a practical approach for clinicians implementing amalgam bonding.
