Dental implants and related therapy: implant therapy in compromised jaw bone

implications of platform-switching; ridge
preservation techniques; peri-implantitis therapy.
Description of Research
My major focus of scholarly activity since starting at OSU has been
dental implant research. Currently, we conduct studies to: 1)
examine implant stability, radiographic bone loss, implant success
and implant survival rate using the ridge-split technique, in
conjunction with implant placement, on the
thin maxilla or mandible ; 2)
investigate the influence of platform switching (smaller healing
abutment) on the composition of peri-implant crevicular fluid and
how it affects soft tissue healing; 3) assess the effects of a
modified implant abutment design on peri-implant soft and hard
tissue; and 4) determine whether the use of a uniquely-designed polylactic acid membrane can improve the quantitative and
qualitative aspects of new bone formation and ridge preservation
compared to extraction alone.
