<abstract abstract-type="main" id="clr12073-abs-0001"> <title>Abstract</title> <sec id="clr12073-sec-0001" sec-type="section"> <title>Objective</title> <p>The aim of this study was to clinically and histologically analyze the healing of grafted sockets by mineralized human bone allograft (MHBA) and nongrafted sockets, correlating the results with buccal plate thickness.</p> </sec> <sec id="clr12073-sec-0002" sec-type="section"> <title>Material and methods</title> <p>Thirty‐one sockets were randomly split into control (CG) and treatment (MHBA grafted) (TG) groups and, subsequently, into four subgroups according to buccal plate thickness: a ≤ 1 mm and b > 1 mm. Ridge thickness, depth, and height were monitored. Four months after, at implant placement, a bone core biopsy for histologic and morphometric analyses was taken.</p> </sec> <sec id="clr12073-sec-0003" sec-type="section"> <title>Results</title> <p>The differences of buccal height (TG‐a ‐0.27 and CG‐a ‐1.17 mm) and width (TG‐a 0.55 and CG‐a 2.67 mm, TG‐b 0.12 and CG‐b 1.17 mm) were statistically significant. The increase in bone amount CG‐b (28.17%) compared with CG‐a (16.98%) was statistically significant. Soft tissue amount of TG‐b (54.21%) and TG‐a (56.91%) was lower than that of CG‐b (71.83%) and CG‐a (83.01%), both being statistically significant (<italic>P</italic> = 0.002).</p> </sec> <sec id="clr12073-sec-0004" sec-type="section"> <title>Conclusions</title> <p>The results proved that thin buccal plates had a worse outcome on socket healing and that network formation by MBHA not only predisposes a successful implant insertion but also acts as size keeper.</p> </sec> </abstract>
