Foreign Body Reaction to Subcutaneous Implants

2015
Subcutaneously implanted materials trigger the host's innate immune system, resulting in the foreign body reaction. This reaction consists of protein adsorption on the implant surface, inflammatory cell infiltration, macrophage fusion into foreign body giant cells, fibroblast activation and ultimately fibrous encapsulation.

Foreign Body‐Type Reaction following Crown Cementation

Journal of Periodontology, 1977
1. Hazards of the indirect impression techniques for crown fabrication are discussed. 2. A foreign body reaction caused by retained cotton fibers is substantiated. 3. Since the gingival retraction cord is a possible and likely source, placing the cord and choice of instruments is important.

Osseous Foreign Body Reaction in the Hand

Annals of Plastic Surgery, 1980
We report a patient who sustained a puncture wound of the palm and developed an osteolytic metacarpal lesion probably due to an organic foreign body reaction caused by grass and wood.

Symptomatic foreign body reaction to haemostatic alginate

British Journal of Oral and Maxillofacial Surgery, 1994
Kaltostat, a haemostatic wound dressing made from non-woven sodium calcium alginate fibres is becoming more frequently and widely used by practitioners. We report a florid foreign body giant cell reaction elicited by Kaltostat which had been used to obtain haemostasis in an apicectomy cavity on an upper lateral incisor approximately 7 months earlier ...

The foreign body reaction

2012
The foreign body reaction is examined as a continuation of a normal inflammatory response. A brief discussion is presented of some of the problems and artifacts inherent in the testing of soft tissue reactions to artificial implants. The process of inflammation and wound healing in presented.

Orthosorb: A case of foreign-body reaction

The Journal of Foot and Ankle Surgery, 1995
The authors present a previously unreported foreign-body reaction to poly-p-dioxanone pin fixation of a distal first metatarsal head osteotomy. The reaction was diagnosed by fine-needle aspiration under fluoroscopic guidance and computed tomography scan.

Endotoxin contamination delays the foreign body reaction

Journal of Biomedical Materials Research Part A, 2011
AbstractBiomaterials are at continuous risk of bacterial contamination during production and application. In vivo, bacterial contamination of biomaterials delays the foreign body reaction (FBR). Endotoxins such as lipopolysaccharides (LPS), major constituents of the bacterial cell wall, are potent stimulators of the immune system in vitro and in vivo ...

The foreign body reaction—an experimental protocol

Journal of Biomedical Materials Research, 1974
AbstractA comprehensive protocol is presented for the in vivo evaluation of soft tissue foreign body reactions to surgical implants. A number of methods of evaluation and quantitation of the tissue reaction to implants are presented and discussed.

Experimental Foreign Body Reactions to Toothpaste Abrasives

Journal of Periodontology, 1976
Some clinical oral foreign body reactions have been reviewed. The testing of the foreign body potential of substances used as abrasives in toothpastes has shown a number to be capable of this. The clinical implications are briefly discussed. The initial studies were conducted when the author was on the faculty of the School of Dentistry, University of ...

Foreign Body Reactions to Plastic Implants

Journal of Macromolecular Science: Part A - Chemistry, 1970
Abstract There are three types of foreign body reactions to plastic implants: 1) reactions due to physical characteristics of the implant, 2) reactions due directly to chemical properties of the implant, and 3) immune reactions. Responses which vary with the physical properties of the implant are epithelial encapsulation of the plastic, epithelial ...
