The next patient broke her upper first molar biting on a hard piece of food.

Fractured teeth of the day. Every day I see broken teeth. Here are 2 examples from today.

This patient cracked his molar biting a chicken bone. I was able to save the tooth, and without a root canal, but it did require a crown lengthening periodontal surgery and a crown.

This next patient bit down on a mint candy and fractured her molar down the root. The tooth could not be restored and was extracted and we will place a dental implant.

Implant case of the week.

This was a challenging implant restoration case due to the alignment of implants. In order for the implant to osseointegrate  firmly into the jaw bone we like to place the implants where the jaw bone is the thickest and strongest. In this case the best bone was not lined up nicely so we had to stagger the implants. I was still able to make the final implant crowns line up perfectly in the mouth.

Before and After

Retention Grooves to help crowns last longer.

On these 2 crowns, the first porcelain and second gold, that I did last week in my office I show how I place retention grooves in my crown preparations to help lock my crowns in. These grooves prevent rotation and help secure the crowns in place. These slots allows for more surface area for the cement and results in a longer lasting restoration that holds firmly in place. This is especially important in short weak teeth. With this technique I am able to save teeth that otherwise would need to be extracted or require periodontal crown lengthening surgery.

Two patient’s smiles I made happy today.

The first patient was concerned about his broken down front upper teeth and the gap between the teeth.

The next patient broke her lateral incisor tooth. It is very dark since it was traumatized and had a root canal many years ago.

Thank you letter from one of my patients last week :-)))

For 44 years, I have been practicing dental hygiene in Virginia.  Recently I had to have a crown prep done on #8 and a replacement crown on #9.  My first crown on #9 was stainless steel, placed at age 7 in 1958.  Since then this tooth has had 14 replacement crowns that improved the appearance as dental materials progressed over the years.
 
My new ones though are the best I’ve ever had made.  The contacts, size, shape, color & occlusion are perfect and needed no adjustments when they were delivered.  I experienced no discomfort during the procedure, even while wearing the temporaries.
 
I have seen thousands of crowns & fillings by hundreds of dentists over my long career and Dr. Gentry’s work surpasses them all.  He is extremely attentive to detail.  The perfect fit and aesthetics are evident in every restoration he does.  I have no reservations in recommending his work to family, friends & current patients.  His sensitivity and approach while interacting with patients is a model for all individuals interested in entering the profession.
 
I truly feel he is deserving of the recognition equal to his daily accomplishments in the field of dentistry. As a dental hygienist with 44 years of private practice experience, I know who the best dentists are, and Dr. Gentry is one of the best!
I highly recommend Dr. Gentry. His dental work is the best I have seen. 
 

Sincerely,

Fractured molar

This patient fractured the lingual side of his first molar tooth biting down on a Skittle candy. Dr. Gentry was able to restore the tooth with a porcelain crown and was able to avoid a root canal and crown lengthening periodontal surgery.

Importance of taking a radiograph to verify accurate interface of the custom abutment to implant.

In this case report Dr. Gentry demonstrates the importance of taking a radiograph when seating the custom abutment and crown before final torquing of the gold implant interface connecting screw.

Now the gold screw can be tightened to 20 Newtons per centimeter squared with the torque wrench.

Here’s an example from a case I was doing with a dental student involving the 2 upper front teeth. In the first x-ray the impression copings were not fully seated. I re-positioned the copings and another x-ray was taken to confirm proper alignment. You cannot tell without an x-ray since this is below the gum-line.

Here’s an example of another implant check x-ray to verify proper seating.
