Summary: | 碩士 === 國立成功大學 === 材料科學(工程)學系 === 85 === Owing to the characters of titanium and it's alloys such
as, strength ,density, corrosion resistance, and
biocompatibility, they were studied extensively in the dental
area, and applied clinically in the human body in recent years.
Since the titanium is easy to be oxidized in the high
temperature, during the process of sintering porcelain on
titanium a thick oxidation layer will be formed quickly on the
surface, which will make the porcelain easy to be delaminated.
Thus there are still lots problems with firing porcelain on
titanium. Being restricted to the appearance, the titanium
couldn't be used more extensively on the dental restoration.
In order to overcome the problem that taking titanium as the
basemetal results in the failure of coated porcelain, our
experiment is trying to replace the porcelain by applying the
composite resins to coat on commercial pure titanium as a
restorative material. The different sand blasting pressure, and
different curing condiction are selected as variables to observe
the changes of bonding strength. The result shows the high
roughness the high bonding strength it is. The experiment result
also points that the bonding strength of composite resin/Ti is
much higher than the one of porcelain/Ti, and also higher than
the one of porcelain/Ni-Cr-Mo.
