{"product_id":"alef-lock-attachment-system","title":"Alef Lock Attachment System","description":"\u003cp\u003eThe Alef lock attachment system is a low-profile overdenture retention system. A lock abutment (Ø3.85 mm) is screwed onto the Alef implant, a metal housing is processed into the denture, and a silicone cap provides retention. Because the profile is low, the system works well where vertical space is limited. This page keeps the whole system together: straight lock abutments, angled lock abutments for non-parallel implants, and all the housings, rings and caps, each ordered individually.\u003c\/p\u003e\u003ch2\u003eStraight lock abutments\u003c\/h2\u003e\u003cp\u003eStraight lock abutments (LOCK05, LOCK1–LOCK6) are offered in heights of 0.5 to 6 mm to match the soft-tissue thickness.
