  1. Asterisk (*) presents a significant difference between undersized and normal osteotomy preparation protocol in each Implant apex design. Different small case letters in horizontal rows show a significant difference among different Implant apex design in each osteotomy preparation protocol. Different capital letters in vertical lines show a significant difference among different Bone quality in each Intraosseous depth. Different numbers in vertical lines show a significant difference among different Intraosseous depth in each bone quality. (p < 0.05).
