However, this material has a poor affinity to cells and tissues, which needs to be overcome for bone implant applications.
Other obstacles must be overcome before brain implants become practical.
This problem was overcome by subcutaneously implanting osmotic mini-pumps containing VLB.
Therefore, in this study, a polydopamine film was used as an intermediate layer to immobilize HA and collagen type I on a medical grade stainless steel (SS316L) implant to overcome those disadvantages.
To partially overcome these issues, ocular implants have been developed for some posterior segment indications; however, the majority require surgical implantation and removal at the end of the intended treatment period.
The modification of surface features such as nano-morphology/topography and chemistry have been employed in the attempt to design titanium oxide surfaces able to overcome the current dental implants failures.
Zygomatic implants could overcome the possible problem of lacking or poor-quality bone [2, 5, 12, 15 22].
Such degeneration could interfere with therapeutic strategies such as the future application of artificial retinal implants to overcome lesion-induced visual impairment.
In complex revision surgery, modular uncemented femoral implants may overcome the limitations of non-modular and mostly straight stems for example, the difficulty in establishing femoral leg length, femoral anteversion, and soft tissue tension (Berry 2002, Mumme et al. 2004, Gutierrez et al. 2007).
Poor fixation of bone replacement implants, e.g. the artificial hip, in implantation sites with inferior bone quality and quantity may be overcome by the use of implants coated with a cultured living bone equivalent.
