What is the purpose of this trial?

The primary aim of the study is to determine the amount of newly formed vital bone, residual graft material, and "connective tissue/other" 18 to 20 weeks after ridge preservation is performed using DFDBA fibers alone, DFDBA particulate alone, a combination of xenograft and DFDBA particulate, or a combination of xenograft and DFDBA fibers.

Are You a Good Fit for This Trial?

This trial is for non-pregnant women, including those post-hysterectomy, tubal ligation, or menopause. Participants should be nonsmokers or light smokers (less than 10 cigarettes per day), have a tooth excluding molars needing extraction with enough bone height and space for an implant. Those with active infections other than periodontitis, heavy smokers, certain medical conditions affecting healing, or on specific medications are excluded.

Inclusion Criteria

My tooth socket's bone wall is partially broken but not more than half.

I have enough jawbone height for dental implants without affecting my sinus or nerve canal.

I am a woman who cannot become pregnant due to surgery or menopause.

Exclusion Criteria

Will not cooperate with the follow-up schedule

My jawbone is not suitable for dental implants.

If I become pregnant during the study, I will be withdrawn.

What Are the Treatments Tested in This Trial?

Interventions

• Ridge Preservation
• Vallomix
• Vallomix-F
• Vallos
• Vallos-F

Trial Overview The study aims to compare the effectiveness of different graft materials in dental ridge preservation after tooth extraction. It will measure new bone formation using DFDBA fibers alone versus particulate form and combinations with xenograft material over approximately 18-20 weeks.

How Is the Trial Designed?

Group I: Group 1 Vallos (DCP) Active Control 1 Intervention

Subjects will be randomized into this group and receive DFDBA particulate alone

Group II: Group 2 Vallomix (DCF) Active Control 1 Intervention

Subjects will be randomized into this group and receive DFDBA fibers alone

Group III: Group 3 Vallos-F (DPX) Active Control 1 Intervention

Subjects will be randomized into this group and receive Xenograft combined with DCP

Group IV: Group 4 Vallomix-F (DFX) Active Control 1 Intervention

Subjects will be randomized into this group and receive Xenograft combined with DCF.
