Abstract
A dental implant provided herein includes a body including titanium or titanium alloy and a diamond-like coating on the body. The diamond-like coating has a surface kurtosis Rku value of at least 1.5, a surface skewness Rsk value of at least 1.2, or a combination thereof to have an increase in gingival cell adhesion to the implant in soft tissue surrounding the dental implant when a portion of the dental implant is implanted into a jaw bone.
Claims20
A dental implant, comprising:
- a body comprising titanium or titanium alloy,
- a diamond-like coating on the body, the diamond-like coating having a surface kurtosis Rku value of at least 1.5 to have an increase in gingival cell adhesion to the implant in soft tissue surrounding the dental implant when a portion of the dental implant is implanted into a jaw bone.
A dental implant, comprising:
- a body comprising titanium or titanium alloy,
- a diamond-like coating on the body, the diamond-like coating having a surface skewness Rsk value of at least 1.2 to have an increase in gingival cell adhesion to the implant in soft tissue surrounding the dental implant when a portion of the dental implant is implanted into a jaw bone.
A method of forming a pro-healing coating on a dental implant, comprising:
- adding oxides to a surface of a dental implant by exposing the surface to an acid, the dental implant comprising titanium or titanium alloy;
- forming an amorphous carbon coating on the dental implant by holding the dental implant at a temperature of at least 700° C. for at least 30 minutes in an atmosphere comprising methane;
- and
- annealing the dental implant having the amorphous carbon coating at a temperature of at least 900° C. for at least 1 hour to create a diamond-like coating having a surface kurtosis Rku value of at least 1.5, a surface skewness Rsk value of at least 1.2, or a combination thereof.
1 more element
A dental implant, comprising:
- a body comprising titanium or titanium alloy,
- a diamond-like coating on the body, the diamond-like coating comprising comprises between about 95% and about 97% by weight carbon and between about 3% and about 5% by weight oxygen, the diamond-like coating having a surface kurtosis Rku value of between 1.5 and 3.0, a surface skewness Rsk value of between 1.2 and 2.0, an average surface roughness Ra of between 65 and 100, a root mean square deviation Rq 0roughness of between 65 and 100.
