Abstract
Clinical studies on immediate implant placement for a single anterior maxillary tooth with a facial bone wall defect are rarely reported. To study the clinical outcomes of immediate implant placement combined with flap surgery, guided bone regeneration and non-submerged healing for a single anterior maxillary tooth with a facial bone wall defect. Forty-five patients with a single failing tooth in the anterior maxillary region showing indications for extraction combined with a facial bone wall defect were treated by means of immediate implant placement combined with flap surgery, guided bone regeneration and non-submerged healing. During this study, the implant survival rate, soft and hard tissue dimension changes, pink aesthetic score (PAS), and patient aesthetic satisfaction were assessed at 1, 6, and 12 months post-operatively. At 12 months post-operatively, the survival rate of 45 implants was 100%. Mesial/distal papillary level reduction and midfacial soft tissue recession were measured as 0.53, 0.41, and 0.31 mm, respectively. The thickness of facial bone reduction measured by cone beam computed tomography was 0.94, 0.80, 0.85, 0.82, 0.45, and 0.41 mm at 6 different sites around the implant. The mean PAS and patient aesthetic satisfaction were determined to be 10.58% and 93%, respectively. The proposed surgical procedure is a valuable treatment strategy as assessed by preliminary clinical outcomes.
