The Trouser Technique: A Novel Approach for Peri-Implant Soft Tissue Augmentation

Background/Objectives: Peri-implant mucosa plays a key role in both peri-implant health and aesthetics. Differences in contour and color between implants and natural teeth can negatively affect patient satisfaction, while soft tissue deficiency may lead to complications such as peri-implantitis. Peri-implant plastic surgery aims to improve these conditions. The objective of this study is to describe the trouser-shaped connective tissue graft technique designed to enhance vestibular and interproximal peri-implant tissue volume in a single surgical procedure, and to assess its effectiveness and morbidity. Methods: Ten patients requiring soft tissue augmentation in edentulous areas prior to delayed implant placement were selected. Intraoral scanning was performed before and 6 months after treatment to evaluate tissue thickness gain. Results: Significant soft tissue volume gain was observed at both the coronal (mean: 2.74 mm with a 95% confidence interval of 2.21–3.26 mm) and vestibular (mean: 2.79 mm with a 95% confidence interval of 2.24–3.35 mm) levels in all analyzed positions (p < 0.001). The procedure exhibited low morbidity, with minimal complications and discomfort reported by the patients. Conclusions: The trouser-shaped connective tissue graft technique is effective in increasing peri-implant soft tissue. It allows for vestibular and interproximal tissue augmentation in a single procedure, minimizing tissue contraction and morbidity. This technique could be a predictable and minimally invasive alternative for managing volume deficiencies in peri-implant tissues, particularly in aesthetic areas.
