The purpose of this study was to evaluate the clinical feasibility of using a native collagen physical resorbable barrier made of bovine pericardium to augment localized alveolar ridge defects for the subsequent placement of dental implants.
MATERIALS & METHODS: There were 8 systemically healthy patients with 19 implant sites (aged 35 to 68 years), with inadequate dental alveolar ridge widths, selected for study. All patients completed initial therapy, which included scaling, root planning, and oral hygiene instruction. All ridge defects were augmented with bovine xenograft and a collagen pericardium membrane. Horizontal (width) hard tissue measurements were taken the day of ridge augmentation surgery, or implant placement and augmentation (baseline), and at the 6-month (reentry or uncovering) surgery.
The change in ridge width varied from a loss of 0.2 mm to a gain of 7.8 mm, measured clinically with a mean value of 3.0368 and a median of 2.8 mm from baseline.
The results suggested that pericardium collagen membrane may be a suitable component for augmentation of localized alveolar ridge defects in conjunction with different xenografts.
本研究的目的是评估使用由牛心包制成的天然可吸收胶原蛋白屏障来增加局部牙槽嵴缺损，以便后续植入牙种植体的临床可行性。
选取8例全身健康的患者（年龄35至68岁），共19个种植位点，这些位点的牙槽嵴宽度不足，用于研究。所有患者均完成了初始治疗，包括洗牙、根面平整和口腔卫生指导。所有牙槽嵴缺损均用牛异种移植物和心包胶原膜进行了增量。在牙槽嵴增量手术当天、种植体植入和增量时（基线）以及6个月后的手术（再次切开或暴露）时进行水平（宽度）硬组织测量。
牙槽嵴宽度的变化范围从减少0.2毫米到增加7.8毫米，临床测量的平均值为3.0368，与基线相比中位数为2.8毫米。
结果表明，心包胶原膜可能是与不同异种移植物联合使用以增加局部牙槽嵴缺损的合适组件。
