President Donald Trump praised Sen.
The appointment marks the end of arguably the most turbulent and divisive episode of Trump's presidency.
Hours later, Kavanaugh was sworn in at a private ceremony.
The last minute ambush of Kavanaugh was done with an eye on the upcoming elections by the Democrats, who hoped the battle would reinvigorate their base.
Nearly all Republicans argued that the Federal Bureau of Investigation report provided "no corroboration" of Ford's claims, but at least one Democratic senator, Kirsten Gillibrand (N.Y.), disputed that.
Has political roots.: Kavanaugh joined independent counsel Kenneth Starr's team in 1994 to investigate then-President Bill Clinton.
After Kavanaugh's name was put forward as a potential nominee for the vacant position on the court, Ford came forward with allegations that Kavanaugh had sexually assaulted her under the influence of alcohol when they were in high school.

Trump celebrated the victory at a rally in Kansas shortly afterward, drawing cheers as he announced he had signed the justice's official commission just before his plane landed in the state. He went on to cite the testimony of Christine Blasey Force and "serious allegations" from two other women.
On the other side, Senate Democratic leader Chuck Schumer of NY called the fight "a sorry epilogue to the brazen theft of Justice Scalia's seat".

But he scoffed at the idea that Kavanaugh's nomination, and the tumult it has unleashed, will help Democrats in November's midterm elections.
"They managed to deliver the only thing we had not been able to figure out how to do, which is to get our folks fired up", McConnell said. Conservatives were not going to lose again, like they did with Bork, or settle for a centrist, like they did with Kennedy and Powell for the past 47 years.
The nomination process has ripped open the scabs on the never-healed wounds of polarisation on the USA body politic exactly a month before the mid-term elections to Congress that can determine the future of Trump's presidency.
Kavanaugh's nomination seals a conservative majority on the nine-seat high court, possibly for decades to come.
This takes the Supreme Court down a more conservative path and is a bitter blow to Democrats already fuming at the Republican control of the White House, the Senate and the House of Representatives.
"Truly, Judge Kavanaugh's confirmation is a low moment for the Senate, for the court, for the country".
In an unexpected move on the eve of Friday's vote, retired supreme court justice John Paul Stevens said Kavanaugh's strikingly partisan tone while denying the allegations against him before the Senate judiciary committee last week should disqualify him.
In a chamber where Republicans hold the narrowest of majorities, all senators voted in accordance with party lines, with the exception of Democrat Joe Manchin of West Virginia, who endorsed Kavanaugh, and Alaska Republican Lisa Murkowski, who voted against.
Kavanaugh's nomination was protested from the beginning by Democrats and liberal activists who oppose the judge's conservative record on key issues including abortion, environmental protection, and presidential powers.
Murkowski ultimately withdrew herself from the final tally as a gesture of goodwill toward her Republican colleague, Sen.
Some Democrats are blaming Michael Avenatti, the attorney who represented Kavanaugh accuser Julie Swetnick, for making the case against Kavanaugh less powerful, as she ultimately faced questions about her credibility when she appeared to walk back some of her previous statements and it appeared she had a history of legal disputes.
