Novel nanotechnology to improve osseointegration

Titanium (Ti) and titanium alloys are among the most widely used materials for dental implants due to their excellent biocompatibility, mechanical properties, good machinability, chemical stability and high corrosion resistance.

Despite high clinical success rates greater than 90% in controlled clinical trials, the smooth implants required healing periods as long as six to nine months prior to loading, and were associated with relatively high failure rates in compromised clinical conditions such as poor bone quality especially in the posterior maxilla and specific patient groups such as smokers, diabetics, and oncology patients.

Since Ti is intrinsically bioinert, various approaches have focused on implant surface modifications mainly topographical ones to accelerate and optimize osseointegration, and allow earlier occlusal loading.

In addition to the topographical features of implant, surface chemistry, wettability and charges are   important parameters affecting  peri-implant bone apposition.

Methods used for surface modifications; sandblasting, treatment with fluoric and sulphuric acid and heat treatment.

In vitro study to compare between new surfaces and other commercially available implant surface.
