Results of Soft Tissue Grafting Around Implant in the Mandible Molar Area

Обзор

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.

Подробное описание

This randomized controlled trial is designed to compare two approaches for peri-implant soft tissue augmentation in the mandibular molar region: an autogenous connective tissue graft (CTG) and a collagen matrix. Adult patients with insufficient peri-implant soft tissue thickness will be enrolled and randomly allocated in a 1:1 ratio to receive either CTG or a collagen matrix at the time of implant surgery. Randomization will be performed using a block randomization method, and outcome assessment will be conducted by a blinded examiner.

Clinical and digital evaluations will be performed at predefined time points, including baseline and follow-up visits up to 9 months after surgery. Peri-implant soft tissue thickness, width of keratinized tissue, and soft tissue contour changes will be assessed using standardized clinical measurements and digital workflows based on intraoral scanning and cone-beam computed tomography where indicated. Postoperative healing and adverse events will be monitored throughout the follow-up period.

The study is conducted at a single academic center and is intended to provide comparative clinical data on the effectiveness and safety of collagen matrix versus connective tissue grafting for peri-implant soft tissue augmentation.

Вмешательства

  • Устройство 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.
  • Процедура 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.
