The objective of this case series was to evaluate the clinical and histologic outcome of guided bone regeneration around simultaneously placed implants in sites with missing buccal bone walls. Eight weeks after tooth extraction, implants were inserted, and the sites were augmented in both the horizontal and vertical dimensions using a mineralized collagen bone substitute and a nonresorbable titanium-reinforced membrane. Six months later, small hard tissue biopsy specimens were harvested from the buccal bone walls at approximately mid-height of the original defect. The histologies revealed ongoing bone formation. Clinically, an adequate amount of hard and soft tissue volume had formed.
本病例系列的目的是评估在颊侧骨壁缺失部位同时植入种植体周围引导骨再生的临床和组织学结果。拔牙8周后植入种植体，并使用矿化胶原骨替代物和不可吸收的钛增强膜在水平和垂直方向上对种植部位进行增量。6个月后，在原缺损处大约中部高度的颊侧骨壁采集小的硬组织活检标本。组织学检查显示骨形成仍在进行。临床上，已形成了足够量的硬组织和软组织体积。
