Dental health maintenance organizations and plans that use a preset benefits schedule may do the best job of holding down claims this year.

Researchers at the Segal Group Inc., New York, have published data supporting that conclusion in a summary of results from an informal survey of Segal’s health plan clients.

Most of the health plan clients included in the survey are large, multiemployer plans.

Underlying dental care costs are on track to rise about 4.3% this year at scheduled plans and dental HMOs, the Segal researchers report.

Cost trends at dental preferred provider organization plans will be up about 5.8%, and cost trends at dental indemnity plans will rise 6.8%, the researchers estimate.
