No membrane was used. Buccal bone wall height was measured by computed tomography in the preoperative period (T0) and 6 to 12 months after procedure (T1). Likewise, buccal\u2010lingual width of alveolar ridge as well as thickness of buccal wall was compared with the contralateral tooth.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> Fourteen patients were selected. Buccal wall height at T1 was not significantly different after 6 to 12 months between the treated and contralateral teeth, although both were greater than T0 (<jats:italic>P<\/jats:italic> &lt;0.01). The heights ranged from 6.4 to 16.30 mm at T0, 12.8 to 25.6 mm at T1, and 14.8 to 25.29 mm in the contralateral teeth. Significant differences were observed between treated teeth (T1) and their contralateral, both buccal\u2010lingually in the alveolar ridge (<jats:italic>P<\/jats:italic> = 0.007) and in buccal wall thickness (<jats:italic>P<\/jats:italic> = 0.003). Wall thickness ranged from 0.9 mm to 3.81 mm at T1 and 0.25 mm to 1.60 mm in the contralateral teeth.<\/jats:p><jats:p><jats:bold>Conclusion:<\/jats:bold> Immediate implant placement at dehiscence buccal bone sites using flapless surgery combined with xenograft blocks provided complete formation of the buccal bone wall up to the implant
