Direct vs. indirect restorations: 10-year outcomes
Researchers compared the long-term outcomes of direct and indirect restorations.
In a study published in the Journal of Dentistry, investigators analyzed the tooth survival rates in more than 189,000 patients with extensive dental defects who received either extensive direct restorations via fillings on three or more surfaces or single dental crowns between 2014 and 2019.
After a follow-up of up to 10 years, the investigators discovered that the survival rates for indirect restorations were greater compared with those for direct restorations — the latter of which required more frequent retreatments and tooth extractions. The risk of extraction was higher among those who received previous root canal treatments or had a post and core.
Further studies are needed to validate the results and better understand the relationship between direct and indirect restorations and long-term tooth survival.
