FAQs
How many implants are needed for an overdenture?
Mandibular overdentures require minimum 2 implants, though 4 provides better stability. Maxillary overdentures typically need 4-6 implants due to bone density differences.
What is the difference between bar and locator attachments?
Bar attachments connect implants with a milled bar, providing rigid splinting and lateral stability. Locators are individual attachments offering easier hygiene but independent implant movement.
How often do attachment components need replacement?
Locator inserts typically need replacement every 6-12 months depending on patient habits. Bar clips may last 2-3 years. Regular maintenance appointments are essential.
