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.

摘要

目的

评估胶原基质（CM）移植物作为游离龈移植物（FGG）的替代品，增加周围角化组织（KT）在牙种植体的有效性。

方法

招募了 30 名有 2 个对侧植入物的受试者。实验组（n=30）接受 CM 移植物。对照组（n=30）接受 FGG。临床变量包括菌斑指数、牙龈指数、探诊深度、探诊出血（BOP）和黏膜退缩（MR）。在 1、2 周和 1、3、6 个月时对受试者进行随访。

结果

FGG 导致 30 个植入物中的 28 个（93%成功率）KT 平均增加（3.73±1.93）mm。CM 移植物导致 30 个植入物中的 29 个（97%成功率）KT 平均增加（3.23±1.52）mm。FGG 移植的植入物周围袋深度平均变化为-0.24±1.02mm，CM 为-0.25±0.80mm。FGG 移植的植入物周围 BOP 平均变化为 0.03±0.49，CM 为 0.13±0.57。
