A 16-year-old girl presented with the worst case of ectodermal dysplasia I had ever seen.. She was missing all of her lower teeth except for her 12-year molars. She presented with a lower denture (made by a previous dentist) on two temporary implants in the canine position.  She had only a few maxillary teeth that were malformed; some of these were still her primary teeth.  The appearance of her smile made her look like she was a 9 year old child. 

She was embarrassed by her smile and realized she would need implants and restorative dentistry down the road. At the time, she was too young. Our hearts went out to her. 

Another dentist had recommended direct bonding, which certainly could have worked, but I thought that we could get a better aesthetic result for her with significantly less time in the chair. So, we captured preclinical digital impression scans with our iTero scanner and along with Matt Roberts at CMR Dental Lab in Idaho, we designed a digital wax-up for an improved occlusion and smile. From there, we had milled PMMA (Polymethyl Methacrylate) overlays created that we direct bonded onto the existing dentition as a long-term temporary solution. We did not need to prep any teeth, and we quickly gave her a broad beautiful smile that looked natural and age appropriate. 

She was in tears. We were in tears. Her mom and sister were in tears. It was the best day ever! 

Soon after, she got a part as an extra in a series filmed here in Georgia, and is thinking about a career in acting. Seeing her life change with simple, comfortable clinical procedures has been priceless.

A situation occurred in my office when I was working with a patient who needed a 30-year-old PFM crown replaced on #8. I was struggling with the shade because the adjacent teeth were an in between color. What I did was take a shade photo of the brightest one, which was B1, and then I took a shade photo with A1–because those were the two shades that matched the best. They weren’t what we were looking for. So, I made a provisional out of the A1 shade and a a provisional out of the B1 shade. I took the extra time to place both of them onto the tooth and let the patient look with me and help me decide. The patient chose the A1 shade. 

After I placed the A1 provisional, we sent  photos to my lab. These photos included the first shade photos of B1 and A1 alongside the tooth, photos of the B1 and A1 provisionals, and photos of the provisional I placed on the tooth from various aesthetic views. I then talked to the lab over the phone while we viewed the photos together so they could create the right in-between shade.  

At the end of the process, my patient expressed gratitude for taking the extra steps and meeting her expectations for a beautifully blended smile. 

Why Use an Essix Retainer Versus a Flipper During Dental Implant Therapy 

Lee Ann Brady, DMD 

When it comes to choosing a provisional during implant therapy in the anterior aesthetic zone, we have two removable options. One is called a “flipper.” It’s an interim partial denture composed of an acrylic base and a denture tooth. The other is an Essix retainer.  

There is no question that both options are taxing for the patient for the three to five months that the patient is edentulous and must deal with having this removable device to replace the tooth. So, I always tell my patients that they are going to have to manage the provisional for that time, but it’s worth it because, in the end, they have replaced the tooth with an implant with all the benefits of an implant versus an alternative prosthetic solution. 

In my practice, I use Essix retainers in nearly 100% of the cases. Why? Because an Essix retainer is tooth-borne. The pressure is placed on the teeth and not on the surgical site. In the case of a flipper, the prosthesis is primarily tissue-borne with a little pressure placed on the adjacent teeth. We really don’t want any pressure on the surgical site while it is healing. Pressure can induce biological problems in bone grafts and connective tissue, which affect the long-term outcome. From an aesthetic perspective, the most challenging thing about anterior implant aesthetics is replicating the size, shape, and position of the tissues of the alveolar ridge and papilla. I want to do everything I can to eliminate pressure on the healing tissue. 

In my practice, we do Essix retainers that don’t have a full solid tooth in them. Instead, we simply paint flowable on the facial so that there’s zero pressure anywhere around that surgical site after extraction, after grafting, and after implant placement.  

In addition to explaining the improved outcomes associated with using an Essix retainer, I assure my patients that the retainer will be more comfortable to wear than a denture and be easily removed by them for eating, for drinking liquids other than water that are likely to stain the retainer, for teeth cleaning, and for cleaning the prosthesis. When out in public, such as in a restaurant, patients may carefully eat while wearing the Essix retainer.
