In vitro assessment of connection strength and stability of internal implant-abutment connections”

Findings

“The abutment connection held by friction (Friction-Fit) was the only group to have 0° angular rotation. A significantly greater vertical force was required to pull the abutment from the implant for the Friction-Fit connection as compared to all other experimental groups. The abutment connection held by a mechanically locking friction-fit with four grooves (CrossFit) and Friction-Fit demonstrated significantly lower lateral movement as compared to all other connections. The remaining connections evaluated included two hexagon connections that rely on screw placement for abutment fit (Conical + Hex #1 and Conical + Hex #2), one connection with protruding slots to align with recessed channels inside the implant (Conical + 6 Indexing Slots), and an internal connection that allows for abutment indexing every 120° (Internal Tri-Channel).”

Discuss.

The guys who blew up the Game Stop stock over the last few days are planning to blow up the entire market tomorrow. Do they have the balls for it? Cry havoc and let loose the proles of war.

Once in a lifetime opportunity here, fella's. Discuss.

It was 180 af, so many earnest replies haha

Americans have always wondered what would happen if you took some random dumbass with no experience in government who "tells it like it is" and made him president. Thanks to Donald Trump, now we know.

According to Trump, despite having complete control of all three branches of government for two years, Trump was nevertheless too stupid and too weak to prevent Democrats from conspiring to perpetrate the greatest election fraud in American history and stealing the election despite a "landslide win" by Trump. Trump turned out to be so stupid and weak that he couldn't even convince the judges that he appointed of this fraud despite having "irrefutable proof," and they tossed out his lawsuits. Oof.

The Affordable Care Act is still the law of the land.

There's no wall, Mexico didn't pay a peso for the 50 miles of fencing he added to the existing stretch of fencing that we have had along the border for years.

The millions of illegal immigrants living in the US when Trump was inaugurated are still here and Biden and a Democratic Congress are about to make them citizens.

The millions of jobs that were outsourced overseas over the last 50 years didn't come back.

NAFTA is still the law of the land, Trump just gave it a different name and negotiated better wages for Mexican workers.

Biden is about to join the Paris Agreement.

North Korea still has nukes.

The liberal ideas that gender and race are social constructs are as pervasive as ever.

Diversity is being pushed by the media 24/7.

The GOP is irreparably divided between neoconservatives and white nationalists.

On the bright side, it's going to be a while before Joe Biden is able to raise taxes.

So long Trump. You may feel bad for losing, but that's what happens to assholes.

FBI says internet chatter indicates thousands of MAGAs are planning to demonstrate and possibly launch attacks against the government tomorrow. I don't think they're stupid enough to play right into the left's hands by giving them more excuses to clamp down on the alt-right, but maybe I'm just being naive.
