Magnets have become very popular as retainers for removable prosthesis overdentures for both root and implant abutments. The advantages of magnetic retention over either bars or stud attachments are:

• No specific path of insertion is required (good for limited dexterity patients)
• No abutment parallelism is required
• Soft tissue undercuts may be engaged
• Potentially pathologic lateral or rotating forces are basically eliminated providing maximum abutment protection
