Ceramic orthodontic bracket bond strength on dental porcelain is clinically sufficient, especially with tensile debonding. Careful composite removal and polishing preserve the porcelain surface, similar to enamel bonding.

Area of Science:

  • Dental Materials Science
  • Orthodontic Technology
  • Biomaterials Engineering

Background:

  • Dental porcelain surfaces present unique challenges for orthodontic bracket adhesion compared to enamel.
  • Assessing bond strength and porcelain surface integrity after debonding is crucial for clinical success.

Purpose of the Study:

  • To evaluate the bond strength of ceramic orthodontic brackets bonded to dental porcelain.
  • To compare different bonding systems, debonding techniques, and post-debonding surface treatments.

Main Methods:

  • Utilized 200 porcelain samples mimicking maxillary incisors, testing two bracket types, two porcelain surfaces, and two bonding systems.
  • Measured bond strength using an Instron Universal testing machine; analyzed surface integrity via scanning electron microscopy.

Main Results:

  • Tensile debonding methods minimized porcelain surface damage.
  • The Ormco primer-Concise system demonstrated significantly higher bond strength than Scotchprime-Transbond.
  • Specific composite removal and polishing techniques effectively restored the porcelain surface finish.

Conclusions:

  • Bonding ceramic brackets to glazed porcelain using silane primer yields clinically sufficient bond strengths, comparable to enamel.
  • Tensile debonding and appropriate surface restoration techniques are recommended to maintain porcelain integrity.
