Abstract
Implant treatment is safe and predictable with sufficient amount and quality of bone tissue. In case of severely reduced bone tissue after a tooth was lost, augmentation of such tissue is necessary before implant embedment. Retrospective evaluation covered 380 alveolar ridge reconstructions. The study material consisted of human grafts prepared by the Department of Transplantology and Central Tissue Bank, Medical University of Warsaw. Presentation of laboratory procedures in the context of physical parameters of frozen, radiation sterilised, allogeneic corticocancellous material was presented. The preparation process makes it possible to obtain two types of bone material: granules and blocks. Women underwent 164 procedures with the use of bone granules and 61 augmentations with bone blocks. In case of men 122 packages of granules were used as well as 33 bone blocks. Based on the results an evaluation of usability of available allogeneic grafts was performed with reference to planned alveolar ridge augmentation procedures, which they were used for.
-
1.
The opportunity to prepare allogeneic material of different textures allowed selection to meet augmentation requirements while providing biological safety.
-
2.
Allogeneic granules should be used in multi-wall defects, such as a double, closed sinus lift and post-extraction socket augmentation.
-
3.
Owing to their superior mechanical parameters, bone blocks were successfully used in extending the width and height of the alveolar ridge and in open sinus lifts with one-wall or two-wall defects and adequate location of the lamellar bone in a graft prevented substantial graft resorption.
