Holding a DENTAL PROSTHESIS in place by its design, or by the use of additional devices or adhesives.
Devices implanted to control intraocular pressure by allowing aqueous fluid to drain from the anterior chamber. (Hoffman, Pocket Glossary of Ophthalmologic Terminology, 1989)
A ready-made or custom-made prosthesis of glass or plastic shaped and colored to resemble the anterior portion of a normal eye and used for cosmetic reasons. It is attached to the anterior portion of an orbital implant (ORBITAL IMPLANTS) which is placed in the socket of an enucleated or eviscerated eye. (From Dorland, 28th ed)
Chronic inflammation and granuloma formation around irritating foreign bodies.
Synthetic organosiloxane gels that are formed from synthetic polymers of silicone oxide with organic sidechains (polydimethylsiloxane) by lengthening the polymer chains. Unlike silicone elastomers, they are not treated with amorphous silica. They are used as fillers in breast implants.
An anabolic steroid used mainly as an anabolic agent in veterinary practice.
Absence of teeth from a portion of the mandible and/or maxilla.
A broad family of synthetic organosiloxane polymers containing a repeating silicon-oxygen backbone with organic side groups attached via carbon-silicon bonds. Depending on their structure, they are classified as liquids, gels, and elastomers. (From Merck Index, 12th ed)
Synthetic or natural materials, other than DRUGS, that are used to replace or repair any body TISSUES or bodily function.
The process whereby an utterance is decoded into a representation in terms of linguistic units (sequences of phonetic segments which combine to form lexical and grammatical morphemes).
Inability or inadequacy of a dental restoration or prosthesis to perform as expected.
The shrinkage of the foreign body encapsulation scar tissue that forms around artificial implants imbedded in body tissues.
The mineral component of bones and teeth; it has been used therapeutically as a prosthetic aid and in the prevention and treatment of osteoporosis.
An inflammatory process with loss of supporting bone in the tissues surrounding functioning DENTAL IMPLANTS.
Procedures for correcting HEARING DISORDERS.
The testing of materials and devices, especially those used for PROSTHESES AND IMPLANTS; SUTURES; TISSUE ADHESIVES; etc., for hardness, strength, durability, safety, efficacy, and biocompatibility.
Replacement for a hip joint.
The plan and delineation of DENTAL IMPLANT fitting with DENTAL ABUTMENT.
Preprosthetic surgery involving rib, cartilage, or iliac crest bone grafts, usually autologous, or synthetic implants for rebuilding the alveolar ridge.
Characteristics or attributes of the outer boundaries of objects, including molecules.
Surgical insertion of an inert sac filled with silicone or other material to augment the female form cosmetically.
Prostheses used to partially or totally replace a human or animal joint. (from UMDNS, 1999)
Materials incorporated mechanically in plastics (usually PVC) to increase flexibility, workability or distensibility; due to the non-chemical inclusion, plasticizers leach out from the plastic and are found in body fluids and the general environment.
An ester of phthalic acid. It appears as a light-colored, odorless liquid and is used as a plasticizer for many resins and elastomers.
Supplies used in building.
