Tooth Loss Clinical Trial
Official title:
The Esthetic Effect of Bio-OSS Collagen® on the Mid-facial Gingival Dimensions When Placed Into Gaps Between 3i® Implants Placed Into Fresh Extraction Sockets and the Labial Plate of Bone
This study compares two ways of placing a dental implant on the day of tooth extraction. One
method will place a additional bone graft (derived from bovine bone) and the other group will
not have the graft placed. Both groups will be restored at the same time with an immediate
crown.
The investigators will be researching and comparing the changes in gum level that occur after
each surgical method, as well as changes in jaw width where the implant is placed.
The investigators will enroll 16 patients per group. The patients will be followed for 3, 6,
and 12 months post-immediate implant placement to observe healing.
The purpose of the current study is to evaluate the soft tissue dimensional changes after extraction of teeth in the esthetic zone, when combined with the placement of implants into these fresh extraction sockets. In addition, the effect of placing a graft material, such as Bio-Oss Collagen® into the gap between implant and the labial plate of bone will be evaluated after an immediately loaded provisional restoration is placed. 32 subjects will have an immediate dental implant placed in the maxillary anterior region (#4-12) after extraction of a hopeless tooth. 16 subjects will be randomly selected to receive Bio-Oss Collagen® (Test group) and 16 subjects will have no graft (Control group) in the gap between the implant and the labial plate of bone. Hopeless maxillary anterior teeth will be extracted and implants will be placed in a flapless procedure. Implants will be immediately loaded with provisional restorations once determined that the implant is stable. Changes in vertical height and horizontal dimensional changes of the free gingival margins will be evaluated at 3, 6, and 12 months post-immediate implant placement. ;
