Effects of Ribose Cross-Linked Thick Collagen Membranes and Connective Tissue Grafts on Peri-Implant Tissue

Ömer Alperen Kırmızıgül·interventional·Posted Mar 17, 2025·Updated Dec 9, 2025

In Brief

A clinical study evaluating Connective Tissue Graft and Ribose Cross-Linked Thick Collagen Membrane for Peri-implant Mucosa Thickness and 2 related conditions. Completed, enrolled 20 participants across 1 site.

Detailed Summary

Background:This study aimed to compare the effect of ribose cross-linked thick collagen membrane (RCCM) with that of subepithelial connective tissue graft (CTG) in sites with soft tissue deficiency in the horizontal aspect around the implant. Methods:Single implant sites were included in the study of 20 systemically healthy patients. All procedures were performed concurrently with implant placement; SCTG was administered in ten patients, and RCCM in the other ten. Before the operation, the PIMT and peri-implant mucosa width (PIMW) were measured. Visual analog scale (VAS) and Oral Health Impact profile-14 (OHIP-14) scores were recorded on post-operative days 1, 3, and 7. At 1 and 3 months measurements were repeated. Results:In terms of PIMT, an average increase of 1.87 mm was recorded in the RCCM group and 1.99 mm in the SCTG group. The rate of increase in PIMT was statistically similar in both the groups (p\>0.05). The OHIP-14 and VAS scores were similar between the groups on days 1, 3, and 7. There was a decrease at 3 months in both the groups. Conclusion:Within the limits of this study, RCCM provided a similar increase in PIMT as SCTG. RCCM is a promising alternative to SCTG for increasing the PIMT. Keywords: Collagen, Connective tissue, Dental implants, Oral mucosa

Interventions

Connective Tissue Graftother

Implant treatment was performed in 20 patients with a single tooth deficiency and soft tissue deficiency in the horizontal direction in the edentulous site. All patients received bone-level titanium implants. Soft tissue augmentation was performed simultaneously with implant treatment. The group were divided into CTG , and 10 patients were randomly assigned to group.
