Abstract

Purpose: To evaluate the effectiveness of collagen matrix (CM) grafts as an alternative to free gingival grafts (FGGs) in increasing the zone of keratinized tissue (KT) around dental implants.

Methods: Thirty subjects with 2 contralateral implants were recruited. The test group (n = 30) received CM grafts. The control group (n = 30) received FGGs. Clinical variables were plaque index, gingival index, probing depths, bleeding on probing (BOP), and mucosal recession (MR). Subjects were followed at 1 and 2 weeks and 1, 3, and 6 months.

Results: FGGs resulted in mean gains (3.73 ± 1.93 mm) in KT for 28 of 30 implants (93% success rate). CM grafts resulted in mean gains (3.23 ± 1.52 mm) in KT for 29 of the 30 implants (97% success rate). Mean change in pocket depth around implants grafted with FGG was -0.24 ± 1.02 mm and with CM was -0.25 ± 0.80 mm. Mean change in BOP around implants grafted with FGG was 0.03 ± 0.49 and with CM was 0.13 ± 0.57.

Conclusion: CM grafts achieved results comparable to those of FGGs in augmented tissue. They do not negatively affect probing depths, MR, or bleeding on probing.

异种胶原基质与游离牙龈移植物增加功能性种植体周围角化黏膜面积的比较。

目的:评价胶原基质(CM)移植物作为游离牙龈移植物(FGGs)的替代品在增加种植体周围角化组织(KT)区域方面的有效性。方法:招募30名受试者，对侧种植体2个。试验组(n = 30)行CM移植。对照组(n = 30)给予fgg治疗。临床变量为菌斑指数、牙龈指数、探诊深度、探诊时出血(BOP)和粘膜退缩(MR)。随访时间分别为1周、2周和1、3、6个月。结果:30个种植体中有28个种植体的KT平均增加(3.73±1.93 mm)，成功率为93%。30个移植体中29个移植体的KT平均增加(3.23±1.52 mm)(成功率97%)。FGG种植体周围口袋深度的平均变化为-0.24±1.02 mm, CM种植体周围口袋深度的平均变化为-0.25±0.80 mm。FGG种植体周围BOP变化平均值为0.03±0.49,CM种植体周围BOP变化平均值为0.13±0.57。结论:CM移植的效果与增强组织中fgg的效果相当。它们不会对探探深度、MR或探探出血产生负面影响。
