Risedronate

Bisphosphonate (oral, antiresorptive)

Brand names: Actonel

Oral health effects

  • Medication-related osteonecrosis of the jaw (MRONJ)

    Exposed necrotic jawbone failing to heal within 8 weeks in a patient on antiresorptive/antiangiogenic therapy without head/neck radiation. Low MRONJ risk in the osteoporosis setting; risk increases with treatment duration.

    Mechanism: Suppressed bone turnover (and/or reduced angiogenesis) impairs healing and remodeling of the jaws after trauma or extraction.

    Clinical management: Optimize oral health and complete invasive work before/early in therapy where possible; prefer non-surgical options and atraumatic technique; refer suspected MRONJ to oral surgery; coordinate with the prescriber.
