The aim of this clinical case series was to evaluate buccal bone thickness using cone beam computed tomography and to demonstrate optimal clinical outcomes for implants placed into extraction sockets in the anterior maxilla with a thin biotype, by placing a graft of mineralized and demineralized human bone allograft into the buccal gap. The preliminary outcomes showed good preservation of soft and hard tissue architecture after 1 year in function. In particular, in eight patients, this allograft mixture appeared to minimize the amount of buccal contour change in the extraction site ridge with a thin buccal plate.
