<p>The structure (600) has a body (601) made of pharmaceutical grade calcium sulphate and calcium phosphate or apatite biomaterial e.g. hydroxyapatite, in the form of porous granules having granulometry by weight of between 250 and 3000 micrometers. The body has an end (602) with an opening (603) prolonged by a central cavity (604) to receive an end of an implant. The granules have a specific surface area of between 10 and 50 meter/gram, where the structure has a ratio by weight of calcium sulphate dihydrate to the porous calcium phosphate or the apatite granules of between 1:3 and 3:1. An independent claim is also included for a tool for creating perforations or cavity in a structure.</p> |
