A low-profile Hader-bar system for implant-supported overdentures with minimum vertical clearance.

A method for treating a minimum vertical clearance maxillary overdenture patient is detailed. A low-profile, cemented, Hader bar with parallel guiding planes is used to stabilize a maxillary implant-supported overdenture. This system maximizes implant support while maintaining simple construction, ease of oral hygiene maintenance, good space for excellent esthetics, and allows enough acrylic bulk for long-term service.
