Bone level female socket O-ring retention insert for the Dentium overdenture system, used as the replaceable retention element within the overdenture housing that engages the ball abutment to provide patient-removable prosthetic retention.

Available Variants (Housing Diameter / Retention Force):

• 4.05 mm — Retention Force 300–500 gf
• 4.85 mm — Retention Force 500–700 gf

Function:

The female socket O-ring is a resilient elastomeric insert that sits within the metal housing embedded in the overdenture base. When the patient seats the overdenture, the O-ring snaps over the bone level ball abutment, providing a tactile, secure retention force. Over time, the O-ring undergoes wear and loses retention force, at which point it can be easily replaced chairside without disturbing the housing or the denture base. The two size and retention force options allow the clinician to match the correct insert to the housing diameter used and to select the appropriate retention level based on the patient’s dexterity and the number of implants supporting the overdenture.

Compatible With:

• Dentium Bone Level Implant System (Standard platform)
• Dentium Ball Abutment and female socket housing (Bone Level)

Indications:

Indicated for use as a replacement retention insert in Dentium bone level ball attachment overdenture systems. Replace when the patient reports reduced retention or when clinical assessment confirms loss of snap retention. Select the variant matching the housing diameter used in the overdenture.
