What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to determine whether the patient's own gum tissue or a pig-derived collagen matrix (Zderm™) works better for gum graft surgery. Both options assist individuals with thin gums around teeth or dental implants. Participants will undergo random assignment to receive surgery with either their own tissue or the collagen matrix. Ideal candidates for this trial include those with dental implants needing gum augmentation and who smoke fewer than 10 cigarettes a day. As an unphased trial, this study allows participants to contribute to important research that could enhance future dental treatments.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research from previous studies shows that using a collagen matrix for gum treatment is generally safe. For example, 8 out of 10 patients experienced complete healing. Another study found that these collagen materials help gums heal without causing harmful effects or complications. Derived from pig tissue, this collagen matrix has been used in gum surgeries for a long time. It offers a safe alternative to using a person's own gum tissue. So far, patients have tolerated the collagen matrix well, with no reports of toxicity or serious side effects.12345

Why are researchers excited about this trial?

Unlike the standard treatment for receding gums, which typically involves using a patient's own tissue from the palate, Zderm™ offers a novel approach by utilizing a porcine collagen matrix. This innovative material aims to simplify the procedure by eliminating the need for a second surgical site to harvest tissue, potentially reducing patient discomfort and recovery time. Researchers are excited about Zderm™ because it could offer a less invasive alternative with similar or improved outcomes in gum tissue augmentation.

What evidence suggests that this trial's treatments could be effective for receding gums?

This trial will compare the effectiveness of a collagen matrix, such as Zderm™, with traditional palatal grafts for treating receding gums. Studies have shown that a collagen matrix can reduce the gap between the gum line and the tooth root by an average of 3.39 mm, covering 43% to 56% of the exposed root. Most patients heal completely within two weeks and experience less pain compared to traditional methods using tissue from their own palate. Additionally, research suggests that the collagen matrix provides lasting results over several years, making it a promising option for treating gum recession. Participants in this trial will join either the collagen matrix group or the palatal graft group to evaluate these outcomes.12346

What Are the Treatments Tested in This Trial?

Interventions

  • Zderm™

Trial Overview

The study compares two types of gum grafts: one uses the patient's own palate tissue, and the other uses a collagen matrix made from pig tendon (Zderm). Patients are randomly assigned to either group during routine dental appointments.
