入选标准

  • Provision of informed consent
  • At least 18 years old
  • In need of one posterior tooth, excluding third molar molars, planned for extraction and replacement with a dental implant (If the subject requires two adjacent socket preservation, they can still be enrolled in the study but only one site will be used for the study)
  • Intact ridge as verified with cone-beam CT scan
  • At least one natural tooth adjacent to the study site present.

排除标准

  • Insufficient interocclusal space to allow for implant supported prosthesis
  • Dehiscence or fenestration identified at the time of reviewing CBCT.
  • Non-treated caries or uncontrolled periodontal disease present affecting the teeth in adjacent to study teeth.
  • Any of natural teeth adjacent to the study site presents active periapical endodontic lesion ("active periapical endodontic lesion" will be determined per consultation by endodontics specialist).
  • Adjacent tooth (mesial and distal) to study site was extracted within last 6 months
  • Adjacent teeth (or tooth) to study site with significant soft tissue loss
  • Smoker using more than 10 cigarettes or equivalent per day
  • Smokeless tobacco use or e-cigarette use
  • Current alcohol or drug abuser
  • Systemic or local disease or condition that would compromise post-operative healing and/or osseointegration e.g. uncontrolled diabetes
  • Need for systemic corticosteroids or any other medication that would influence post-operative healing and/or osseointegration
  • Pregnancy, as indicated by positive serum human chorionic gonadotropin (HCG) test result.
  • Unable or unwilling to return for follow-up visits for a period of 5 months
  • Unlikely to be able to comply with study procedures according to Investigators judgement
  • Subject in other clinical trials

结局指标

主要结局

Change in Radiographic Measurements of Ridge Dimension (Horizontal Ridge Width)

时间窗: Baseline and 4 months post-surgery

Cone-beam computed tomography (CBCT) is taken at the ridge preservation procedure (baseline) and 4 months after the procedure. Linear measurement of horizontal ridge width is measured at 1 mm apical to the crest. Change of horizontal ridge width = (Baseline measurement - 4 months measurement)

Change in Radiographic Measurements of Ridge Dimension (Volumetric Assessment)

时间窗: Baseline and 4 months post-surgery

Cone-beam computed tomography (CBCT) is taken at the ridge preservation procedure (baseline) and 4 months after the procedure. Bone volume measurement is expressed in mm3, which allowed for a calculation of the % of volumetric reduction that took place from baseline to 4 months post-surgery.

次要结局

  • Histomorphometric Assessment of Newly Formed Mineralized Tissue(5 months post-surgery)
  • Histomorphometric Assessment of Non-mineralized Tissue(5 months post-surgery)
  • Change of Marginal Bone Level Around Dental Implant(Baseline, 6, and 12 months after crown delivery)
  • Histomorphometric Assessment of Residual Bone Graft Particles(5 months post-surgery)
