A study on soft tissue grafting around implants.

The purpose of this research study is to determine whether you will have a better outcome with a gum graft harvested from the roof of your mouth or a human tissue graft and how you perceive both discomfort and the esthetics of the graft during the healing period.

A two-arm, parallel group, randomized controlled clinical trial on adult human subjects receiving divergent or concave Atlantis™ abutments to assess peri-implant mucosa changes from prosthesis delivery to 1 year.

• (Primary) Compare the influence of experimental concavities in the subgingival transition zone of Atlantis™ abutments on peri-implant mucosal dynamics from final restoration delivery to one year, as compared to current Atlantis™ abutments with linear divergent transition profiles.  
• (Secondary) Quantify the horizontal soft tissue thickness changes around concave and divergent abutment transition profiles from final restoration delivery to one year.  
• (Secondary) Evaluate changes in peri-implant health indicators, such as Gingival Index (GI), Probing Pocket Depth (PPD), and Bleeding on Probing (BOP).

A research study to evaluate the perceived incidence of post-operative sensitivity when a full coverage all ceramic crown is fabricated in the posterior part of the mouth.

A dental implant research study to compare two different implant abutment designs, micro grooved or machined, in order to determine if these texture differences have any impact on the healing of your jaw bone and gums after implant surgery.

A randomized clinical trial to longitudinally evaluate changes in bone stiffness around dental implants placed in the posterior maxilla.

A randomized clinical trial comparing marginal bone level alterations between 6mm and 11 mm Astra Tech OsseoSpeed implants in posterior jaws.

Determined the anti-inflammatory effect of Simvastatin when applied topically around implants with inflamed gums.
