Brief Summary:
Comparison of the clinical healing of simultaneous vs. delayed grafting for dental implant placement.

Condition or disease Intervention/treatment Phase
Tooth Loss Procedure: Delayed graft Procedure: Simultaneous graft Not Applicable

Detailed Description:
The primary aims of this study are to compare the clinical and histologic results of a traditional ridge preservation with implant placement at 16 weeks (control group) with early implant placement (8 weeks) with simultaneous contour augmentation as described by Buser (test group).

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 7 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Ridge Preservation Comparing the Traditional Approach vs. Early Implant Placement With Simultaneous Contour Augmentation
Actual Study Start Date : November 8, 2018
Actual Primary Completion Date : April 26, 2019
Actual Study Completion Date : April 26, 2019

Arm Intervention/treatment
Experimental: Delayed Grafting
8 weeks after extraction implant placement and simultaneous osseous grafting.
Procedure: Delayed graft
8 weeks post-extraction 15 test patients will receive implant placement plus osseous grafting.

Active Comparator: Simultaneous Grafting
At the time of extraction the socket will be grafted and implant placed 4 months later.
Procedure: Simultaneous graft
At the time of extraction osseous graft will be placed in the socket and implant placed 4 months later.

Primary Outcome Measures :
  1. Final ridge width for simultaneous and delayed grafting treatment. [ Time Frame: 16 to 20 weeks ]
    Measure final ridge width to determine if adequate bone is available.

Secondary Outcome Measures :
  1. Soft tissue thickness [ Time Frame: 16 to 20 weeks ]
    Facial and occlusal

  2. Histology [ Time Frame: 16 weeks ]
    Histologic composition for control group only

  3. Implant dehiscence [ Time Frame: 20 weeks ]
    Implant dehiscence
