Investigating the Process of Cement Line Maturation on Substrate Surfaces with Submicron UndercutsKo, James Chih-Hsien Jr. 06 January 2011 (has links)
The cement line is the first mineralized matrix deposited on an implant surface during contact osteogenesis forming the bone/implant interface. The hypothesis underlying the present project was that non-collagenous cement line proteins must be deposited into the submicron undercuts on substrate surfaces prior mineralization. In vitro osteogenic cultures were used to grow bone nodules on Thermanox® coverslips modified with calcium phosphate nanocrystals, creating an undercutted surface. Electron microscopy was used to observe cement line formation. BSP immunogold labelling was used to determine if the cement line organic matrix is deposited within undercuts prior mineralization. The results showed the deposited bone nodules, and on test coverslips the deposited cement line was thicker and evenly distributed than control. Furthermore, positive BSP labelling was found within the undercuts prior to cement line mineralization. Thus, it can be concluded that cement line proteins are deposited into submicron undercuts on substrate surfaces prior to mineralization.

The Comparative Performance of Micro- and Nano-topographically Complex Endosseous Implant Surfaces in Normoglycemic and Hyperglycemic SubjectsBell, Spencer 11 July 2013 (has links)
Endosseous implants have notably high success rates, yet a small percentage of implants still fail for unidentified reasons. Recent literature points to hyperglycemia, resulting from untreated or undiagnosed diabetes, as a possible contraindication in an otherwise apparently healthy population. To investigate the effect of surface design on peri-implant healing in the presence of hyperglycemia, STZ-treated rats were implanted with custom rectangular implants of two surface topographies: grit blasted (GB) and grit-blast with a calcium phosphate nanotopography (GB-DCD). Tensile testing was conducted at 5, 7, and 9 days post-operative. Results demonstrated hyperglycemia to delay early stages of the peri-implant healing. Contact osteogenesis was increased along the GB-DCD surface, even in an environment of uncontrolled hyperglycemia, and the GB-DCD surface outperformed the GB surface in both healthy and hyperglycemic animals, showing peri-implant bone matured more rapidly on nanotopographically complex surfaces, even in the presence of uncontrolled hyperglycemia.
