First implant experience proves fun

Jan. 1, 2010
It's not often that I praise patients for not following their dentists' advice, but after placing my first implant, this is exactly what I did.

For more on this topic, go to and search using the following key words: implant, alveolar canal, fixed bridges, periapical radiograph, Dr. Michael DiTolla.

It's not often that I praise patients for not following their dentists' advice, but after placing my first implant, this is exactly what I did. Ten years earlier, when this 32–year–old male patient had tooth No. 19 extracted, his dentist suggested a three–unit bridge to replace the missing tooth.

The patient didn't like how much it was going to cost. But more importantly, he opposed the idea of prepping two adjacent teeth to replace one missing tooth, especially when he had no restorations on the lower arch. I told the patient he made a good decision not having the bridge done, since this is what allowed us to place the implant without harming either of the adjacent teeth.

Fixed bridges seem to create as many periodontal problems as the restorative problems they are meant to solve. Throw in the fact that the two abutment teeth could potentially need endodontic treatment now or later, and a compelling case is made for the single– tooth implant.

Fig. 2: Equally important are the placement of the implant and the identification of the inferior alveolar canal. As can be seen, it was well below not only the implant but also the yellow safety zone around the proposed implant. The risk of paresthesia was one of the concerns that prevented me from placing implants for the first 20 years of my career.

I have always known that patients would rather stay in my office than be referred to another, but I was afraid to surgically place an implant. Up to this point, I had been restoring implants for some time and had taken numerous implant courses. But when our lab's implant department convinced me that digital treatment planning technology would eliminate the guesswork, I decided I was ready to give it a try.

Shown here are some step–by–step pictures of my first implant. I can honestly say it was the most fun I have had in a long time, and it was easier than almost any crown prep I have done recently.

The guide will have some inspection windows from which cusp tips protrude so you can verify that the guide is seated completely. The metal sleeve in the surgical template controls the angle and depth of the implant drills.

I wish there was this much technology available to walk me through molar endo, wisdom tooth extractions, or multiple–unit bridge preps.

Looking at the position and angulation of the proposed implant and the actual implant, I am confident that I could not have achieved this result freehand.

I recommend that you take advantage of this technology and use the digital treatment planning expertise of Glidewell's implant department. If your first experience is anything like mine, you will start looking quickly for a second implant case.

Since we planned on placing a NobelReplace™ implant, this case was done using the NobelGuide™ Guided Surgery System.
