Radiographic metrics were evaluated using preoperative, immediate postoperative, and follow\u2010up cone beam computer tomography (CBCT) scans, and esthetic indicators were extracted from follow\u2010up clinical records. The buccal bone arch contour of the edentulous area was reconstructed using the mirror symmetry technique. Implants were grouped based on the relative position of the bone grafts and implant to the contour immediately after surgery for comparisons of radiographic and esthetic outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 66 patients (66 implants) were ultimately included. For simultaneous GBR in the anterior maxilla, a bone gain of approximately 0.55\u20130.75\u2009units was expected for every additional unit of bone graft. Bone grafts augmented outside the buccal bone arch contour tended to resorb back to the contour, suggesting that excessive bone augmentation may not provide significant benefits. Implants placed more than 3\u2009mm palatally from the contour tended to achieve greater buccal bone wall thickness and more predictable esthetic outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The buccal bone arch contour provides an individualized reference for determining the appropriate bone graft volume and implant position. Placing the implant at least 2\u2009mm palatally from the contour and augmenting bone grafts to exceed the contour by at least 1\u2009mm appears to be a practical and effective strategy.<\/jats:p>\n
