*3.1. Manuscript Collection*

Manuscript revision and recording data process followed the PRISMA flow diagram (Figure 1). The initial electronic and hand search retrieved 1197 citations and four more papers from Dentistry, PubMed MEDLINE and Oral Sciences Source with a total of 1201 selected papers. Furthermore, 617 papers were excluded because they were published prior to 1 February 2010. Then, titles and abstracts were evaluated, and 52 articles were selected as having significant data regarding "facial bone reconstruction biomaterials" topics. In addition, 48 articles were determined as full-text papers, 39 of which were incorporated in this work. Some research was excluded due to being classified as single case reports presented (*n* = 4), weak methods or being way off-topic (*n* = 5).
