Osseointegration Of Wrapped Dental Implants In Rabbits, Alex Whitehead
Osseointegration Of Wrapped Dental Implants In Rabbits, Alex Whitehead

Edentulous patients (those lacking teeth) require one of two approaches to augmentation: inserting a vertical bone graft, or subperiosteally anchoring a device on which an implant can be attached. Bone grafts have had unpredictable results and can undergo resorption over time, compromising implant stability and success. As of the subperiosteal approach, current materials have not proven to directly integrate with the bone, in a process termed osseointegration. Therefore, we used additive manufacturing to create a Ti6Al4V alloy surface with a specific roughness to determine if it would be osseoinductive in a challenging rabbit model over six weeks.

Tooth mobility is the major cause of stress on a tooth implant or partial denture and often results in the damage of the device. For many prosthetic devices like dental bridges, a partial denture used for a person who is missing a tooth to give the appearance and function of a tooth, mobility can cause up to double the amount of stress in comparison to a fixed model. Creating a computer simulation of tooth mobility using Finite Element Analysis allows one to understand and predict this movement in order to improve future dental prosthetic devices. The main cause of tooth …
