Defective restoration repair or replacement

by adminjay


Abstract

Background

Clinicians often encounter defective restorations and are faced with the difficult
decision of whether to repair the existing restoration or replace it.

Methods

An electronic survey on repairing or replacing defective restorations was developed
to assess how clinicians are making these decisions and the technical aspects considered
when making a repair. E-mails containing the survey link were sent to the American
Dental Association Clinical Evaluators (ACE) Panel on August 14, 2019, and the survey
remained open for 2 weeks. Nonrespondents were sent reminders 1 week after deployment.

Results

Approximately 4 of every 5 respondents repair defective restorations. The top 3 conditions
for making these repairs were noncarious marginal defects (87%), partial loss or fracture
of the restoration (79%), and crown margin repair due to carious lesions (73%). Among
respondents who repair defective restorations, almost all repair direct resin composite
(98%), whereas approximately one-third do not repair the other restorative materials
(that is, amalgam, glass ionomer, and fractured indirect all-ceramic crowns). Resin
composite is used most often to repair resin direct composite restorations, and likewise,
glass ionomer is used most often to repair glass ionomer restorations. Only 54% of
respondents use amalgam to repair amalgam restorations. Surface treatments varied
among the 3 available restorations types.

Conclusions

Many dentists are actively making restoration repairs, but choosing clinical scenarios
to make these repairs is material dependent.

Practical Implications

The repair of defective restorations is an acceptable and more conservative alternative
than restoration replacement, and its success depends on proper case selection, material,
and technique.
