Zest CHAIRSIDE Attachment Processing Material · Normal Set · 8 g (4 mL) Syringe

The FDA describes endosseous dental implant accessories as manually powered devices intended to aid in placing or removing implants and abutments, to prepare the site for them, to aid in fitting them, to aid in making dental prosthetics, and to be used with implants where tissue contact lasts less than one hour. The list includes drill bits, screwdrivers, countertorque devices, placement and removal tools, laboratory pieces used for making dental prosthetics, and trial abutments, and the class is Class I. An implant-supported overdenture is retained by an attachment matrix housing that sits inside the denture and connects to the implants through either solitary-type or bar-type attachments. That housing is fitted either chairside, called the direct technique, or in a laboratory, the indirect one, and a study notes most practitioners prefer the chairside technique to minimize processing errors.

An endosseous dental implant is a prescription device made of a material such as titanium or titanium alloy, intended to be surgically placed in the bone of the upper or lower jaw arches to support prosthetic devices such as artificial teeth and restore chewing function. The FDA puts root-form implants in Class II with special controls, and describes them as four geometrically distinct types: basket, screw, solid cylinder and hollow cylinder. This shelf holds no implants: it carries accessories for implant-retained prostheses, a bur, and bone graft and collagen dressing materials.

Bone grafting material is defined by the FDA as a material such as hydroxyapatite, tricalcium phosphate, polylactic and polyglycolic acids, or collagen, intended to fill, augment or reconstruct periodontal or bony defects of the oral and maxillofacial region. It is Class II with special controls, unless it contains a drug that is a therapeutic biologic, in which case it is Class III and requires premarket approval. A review sorts bone grafts by source into autografts from the patient, allografts from a different person of the same species, xenografts from another species, and synthetic substitutes made to mimic natural bone.
