alloplastic implant
Pronunciation: AL-oh-plas-tik
Synthetic biocompatible materials used to augment or reconstruct body structures in plastic surgery.
Full Definition
Alloplastic implants refer to synthetic, non-biological materials designed to augment, reconstruct, or replace anatomical structures in plastic and reconstructive surgery. These biocompatible materials include silicone gel or saline breast implants, facial implants made from solid silicone, porous polyethylene (Medpor), or expanded polytetrafluoroethylene (ePTFE). Unlike autologous tissues which use the patient's own tissue, or allografts from donors, alloplastic materials are manufactured devices that integrate with surrounding tissues. Common applications include breast augmentation, facial contouring, and reconstruction following trauma or tumor resection. Selection depends on factors such as biocompatibility, durability, and the specific anatomical requirements of the reconstruction.
Usage
Usage note: Distinguish from allograft (donor tissue) and autograft (patient's own tissue); alloplastic specifically refers to synthetic materials.
In Context
