To report biological and technical outcomes of implant-supported restorations placed into previously maxillary sinus floor augmentation using the lateral wall approach (MSA) using anorganic bovine bone mineral (ABBM) + autogenous bone (AB) (control group) or collagen-stabilized ABBM (test group).
Single implant was placed 6 months after MSA in 27 control and 26 test patients. Fixed restorations were delivered 12 weeks later and reviewed 12 months after function. Outcomes measured included implant survival, marginal bone levels (DIB), peri-implant parameters, and incidence of biological and technical complications.
Seven patients (three control, four test group) did not return for their 1-year review. No significant inter-group differences were noted for all parameters. At baseline (3 months after implant placement), a mean(SD) marginal bone loss of 0.66 mm (0.40) and 0.77 mm (0.48) from the implant shoulder was recorded in the control and test group, respectively. After 12 months of loading, a mean (SD) additional marginal bone loss of 0.32 mm (0.24) and 0.35 mm (0.23) was noted in the control and test group, respectively. Peri-implant mucositis (≥1 site BOP) was diagnosed in 62.9% of control and 69.23% of test patients. No peri-implantitis was diagnosed. Screw retention and single crowns predominated. Technical complications mostly comprised of ceramic veneer chipping and were noted in 7.4% of control and 11.54% of test patients.
Based on a short observation period, implant reconstruction of the partially edentulous posterior maxilla after MSA using ABBM + AB or collagen-stabilized ABBM led stable marginal bone levels, high prevalence of peri-implant mucositis, and low rates of technical complications.
报告使用外侧壁方法（MSA）进行上颌窦底提升后，使用无机牛骨矿物质（ABBM）+自体骨（AB）（对照组）或胶原稳定 ABBM（实验组）植入物支持修复的生物学和技术结果。
在 27 例对照组和 26 例实验组患者中，在 MSA 后 6 个月植入单个种植体。12 周后交付固定修复体，并在功能后 12 个月进行检查。测量的结果包括种植体存活率、边缘骨水平（DIB）、种植体周围参数以及生物学和技术并发症的发生率。
7 名患者（对照组 3 名，实验组 4 名）未返回进行 1 年复查。所有参数均未发现组间差异。在基线（植入后 3 个月）时，对照组和实验组的种植体肩部分别记录了 0.66mm（0.40）和 0.77mm（0.48）的平均（SD）边缘骨损失。在加载 12 个月后，对照组和实验组分别记录了 0.32mm（0.24）和 0.35mm（0.23）的平均（SD）额外边缘骨损失。诊断出 62.9%的对照组和 69.23%的实验组患者存在种植体周围黏膜炎（≥1 个部位 BOP）。未诊断出种植体周围炎。螺钉保留和单冠占主导地位。技术并发症主要包括陶瓷贴面崩裂，在对照组和实验组中分别有 7.4%和 11.54%的患者出现。
根据短期观察期，MSA 后使用 ABBM+AB 或胶原稳定 ABBM 进行部分无牙后上颌骨的种植体重建导致稳定的边缘骨水平、高比例的种植体周围黏膜炎和低技术并发症发生率。
