I am considering the use of the Nobel Biocare Easy Abutments for the restoration of an edentulous maxilla. Has anybody attempted this kind of restoration and what complications did you encounter?

I am replacing #11, 12 and 13 with an dental implant fixed partial denture supported by two 4.0×10mm implant fixtures in #11 and 12 sites. #13 will be cantilevered. For this dental implant design, will make any difference if I use the UCLA type abutment crowns or will cement retention be better?

I have difficulty inserting the abutment into the dental implant fixture. The gingival tissue grows tightly against the healing cap.

The last few cases my lab has returned to me have abutments with pointy tops. They say they leave the pointy tops because it increases the occluso-gingival height of the abutment which increases retention.

I have been hearing a great deal about the problem of bacteria colonizing around the micro-gap between the dental implant fixture and the abutment. Is this a real problem to be concerned with?

I have had two patients ‘break’ the abutment about half way down the dental implant.

A patient asks us:Can someone please give me a basic explanation of the various types of dental implant-abutment attachments?

Are they important in the success of a dental implant? Is there really a difference between the attachments produced by different companies? What is morse taper? Thanks for your help.

I’ve heard that there is a problem around the abutment margin junction on dental implants where bacteria tend to collect.

Ronda asks us:My 18 year old son was in a car accident and needed his 4 top front teeth replaced. He has had bone grafted and the
dental implants are in. My question relates to his abutments.

I have heard that there are different types of abutments on the market. Upon doing some research I have also […]

Dr. Croll asks us:
I use Atlantis custom abutments for cement retained crowns and bridges and usually the fit on single units is excellent.

Occasionally for multiple units I have found the fit of bridges to be a little tight.  Are any of you using die relief to create space for the cement?  I am thinking of […]

For some of my more apprehensive dental implant referrals I place the solid abutment onto the dental implant for them, allowing them to take a conventional crown and bridge impression for the crown.

Have any of you started using one-piece dental implants where there is no dental implant-abutment interface? What is your experience with these implants?

here seems to be some controversy over torquing down the abutment screw when placing dental implants. Most of the dental implant crowns and bridges that I do involve torquing down the abutment and then cementing the crown or bridge.

There are other recent studies that have shown no bone loss with an abutment that was step backed from the implant itself. Some manufacturers have already been offering these types of abutments for quite some time. Is this the future direction for abutments?

What has been your experience with cementing crowns and bridges on implant abutments?
