Modified Periosteal Tissue Graft vs Collagen Matrix for Soft Tissue Augmentation Around Implants: A Comparative Study

January 31, 2025 updated by: heba ahmed abdelmaged, Minia University

Modified Vascularized Interpostional Periosteal Connective Tissue Graft Versus Xenogeneic Collagen Matrix for Soft Tissue Augmentation Around Implant in Esthetic Zone (Comparative Study)

This clinical trial aims to evaluate the effectiveness of the Modified Vascularized Interpositional Periosteal Connective Tissue Graft (mVIP-CTG) compared to Xenogeneic Collagen Matrix (XCM) around immediate implant in esthetic zone . This study will assess outcomes such as keratinized tissue thickness, keratinized tissue width, pink esthetic score and radiographic buccal cortex thickness over a defined follow-up period. By comparing mVIP-CTG to XCM, the study seeks to determine which method provides superior clinical and aesthetic results for best soft tissue augmentation

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study investigates two surgical techniques for managing peri-implant soft tissue deficiencies: the Modified Vascularized Interpositional Periosteal Connective Tissue Graft (VIP-CTG) and the Xenogeneic Collagen Matrix (XCM). Peri-implant soft tissue deficiencies, characterized by inadequate tissue volume or recession around dental implants, can lead to complications such as implant exposure, sensitivity, and aesthetic concerns. Conventional treatment methods aim to enhance soft tissue volume and improve the aesthetic and functional outcomes of implants.

The mVIP-CTG approach utilizes autogenous pedicle grafts to improve tissue thickness and width, potentially enhancing soft tissue integration and thickness around immediate implants. In contrast, XCM is a xenogenic membrane offering a minimally invasive alternative substitute for soft tissue regeneration.

The study design includes randomized assignment of participants to either the mVIP-CTG group or XCM group, with standardized surgical and follow-up protocols. Primary and secondary outcomes will include peri-implant soft tissue thickness, keratinized tissue width, pink esthetic score, and radiographic buccaal cortex thickness. Statistical analysis will evaluate the comparative effectiveness of both techniques in promoting peri-implant soft tissue regeneration and aesthetic recovery.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
keratinized tissue thickness
Time Frame: baseline, 3 months, 6 months
measurement of Kertinized tissue thickness around implant using endodontic file
baseline, 3 months, 6 months
keratinized tissue width
Time Frame: baseline, 3 months and 6 months
measurement of keratinized tissue width using graduated UNC-15 Probe
baseline, 3 months and 6 months
buccal cortex thickness
Time Frame: baseline and 6 months
measurement of buccal cortex thickness using CBCT
baseline and 6 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
