About

This research aims to compare the effectiveness of two bone grafting materials on preserving jawbone integrity after tooth extraction. Following extraction, the jawbone surrounding the removed tooth can shrink, affecting future implant placement. By placing a bone graft material in the extraction socket, we aim to maintain adequate jawbone space for future implants. This study compares how well the mixture of vallos®f (human source bone) and Bio-Oss (animal source bone) [test], and vallos® only [control] grafting materials work.

Participants with at least one tooth planned for extraction and subsequent implant placement are sought for this study. Participants will be randomly assigned to either the mixture of vallos®f and Bio-Oss (test) group or the vallos® only (control) group.

Throughout the approximately 2-year study duration, participants will undergo oral exams, x-rays, surgical procedures, and follow-up visits. All participants will undergo routine tooth extraction, bone graft material placement, and dental implant placement. After the crown is placed on the implant, participants will attend follow-up visits.

Participation in the study is voluntary, and the alternative is to continue routine dental care. Risks include minor discomfort from procedures such as tooth extraction and implant placement. The major benefit of participation in the study is the preservation of jaw dimensions following extraction, which will simplify the placement of a dental implant.

Enrollment: 24 estimated patients

Sex: All

Volunteers: Accepts Healthy Volunteers

Inclusion and exclusion criteria

Inclusion criteria:

1. Provision of informed consent
2. At least 18 years old
3. In need of one posterior tooth (premolar or molar), excluding third molar molars, planned for extraction and replacement with a dental implant
4. Type I or II extraction socket/ ridge identified at the time of enrolment with cone-beam CT scan
5. At least one retained natural tooth adjacent to the study site

Exclusion criteria

1. Insufficient interocclusal or interdental space to allow for an implant- supported prosthesis
2. Previous interventions performed involving soft and/or bone grafting in the study site
3. Active treated caries
4. Uncontrolled periodontal disease present
5. Evidence of active periapical, radicular, or endodontic lesions on teeth adjacent to study site
6. History of recent extraction of an adjacent tooth (mesial and distal) to study site within 6 months of enrollment
7. Current smoker with self-reported history of more than 10 cigarettes or equivalent per day
8. Self-reported use of smokeless tobacco or e-cigarette
9. Self-reported history of current alcohol or drug abuse
10. Systemic or local disease or condition that would compromise bone metabolism, post-operative healing and/or osseointegration e.g. uncontrolled diabetes with self-reported most recent HbA1c > 8.0 within last six-month
11. Systemic corticosteroids or any other medication that would influence bone metabolism, post-operative healing, and/or osseointegration

Masking: Single Blind

24 participants in 2 patient groups

Alveolar ridge preservation with Allograft/Xenograft group

Experimental group

Description:

The patients in both groups will go through the same treatment but with two different bone grafting materials depending on the assigned group. The patients in this group will have alveolar ridge preservation with the mixture of demineralized cortical allograft vallos®f and xenograft bone substitute called Bio-Oss®.

Treatment:

Device: Allograft/Xenograft

Alveolar ridge preservation with Allograft group

Active Comparator group

Description:

The patients in both groups will go through the same treatment but with two different bone grafting materials depending on the assigned group. The patients in this group will have alveolar ridge preservation with mineralized cortico-cancellous bone substitute called vallos®.

Treatment:

Device: Allograft
