CTG Versus Collagen Matrix for Peri-Implant Soft Tissue Augmentation

NCT07371481 · Status: NOT_YET_RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 46

No results posted yet for this study

Summary

This randomized controlled trial compares two techniques for peri-implant soft tissue augmentation in the mandibular molar region: an autogenous connective tissue graft (CTG) and a collagen matrix. Adult patients requiring implant treatment with insufficient peri-implant soft tissue thickness will be randomly assigned to receive either CTG or a collagen matrix at the time of implant surgery.

The study aims to evaluate and compare changes in peri-implant soft tissue thickness, width of keratinized tissue, and soft tissue contour over a 9-month follow-up period, as well as the occurrence of postoperative complications. The results of this study will help determine whether a collagen matrix can provide clinical outcomes comparable to those of connective tissue grafting for peri-implant soft tissue augmentation.

Conditions

  • Peri-implant Soft Tissue Deficiency
  • Insufficient Peri-implant Keratinized Tissue

Interventions

DEVICE

Collagen Matrix

A porcine-derived collagen matrix is used for peri-implant soft tissue augmentation at the time of implant surgery, serving as a substitute for autogenous connective tissue grafting.

PROCEDURE

Connective Tissue Graft

An autogenous connective tissue graft harvested from the patient is used for peri-implant soft tissue augmentation at the time of implant surgery.
