Are some sites not good for dental implants?

Although implants can allow for replacement of teeth in many situations, some sites , even after a bone grafting procedure, do not end up having sufficient depth or width to place a predictable implant. Implants come in standard shapes and sizes and sometimes are either too long or too large a diameter to fit in some ridges.

In truth, there are many designs for implants that might work but are not commonly used , that might work in some of these situations. An early design that was employed for thin alveolar ridges was called a blade implant. The dentist made a slot  in the bone and the blade implant was tapped into place. These were successfully used for many years but because of a higher failure rate than the cylindrical implant systems currently in vogue, they have fell out of favor.

In my mind, given the desire for many patients with narrow ridges that are challenges to restore with our more modern implant designs , it is time for our dental schools to research alternative techniques and protocols that may allow the placement of more narrow implant designs for "tight spaces". Using different protocols it it quite likely that blade implant systems or some other design will work in sites that most dentist are loathe to place a cylindrical implant system.

Help! My Child is Terrified of the Dentist

Image
If you’re the parent of a young child, you know their brains are similar to sponges that soak up everything around them—especially in their first five years, which neuroscientists say is when they’ll do the most learning and developing in their entire life. At this formative time, your child may amaze you with what they notice: your facial expressions, the different tones of your voice, and your habits. If your habits include regular dental visits and an excellent oral hygiene routine, they’ll notice and want to emulate you. If you happen to feel anxious about your dental visits, or you groan when you’ve got to floss and brush, they may synchronize and feel your dread. This could lead to dental fears that stick with them for years—potentially a lifetime! Kids Can Be Courageous If you’re feeling guilty right now, go ahead and put that away as it won’t serve you or your little one. Everyone has some room for improvement, and Coastal Pediatric Dentistry® is here to help show you an

Going for the Gold?

Image
On the left is the older allow, on the right the new one that my lab has chosen to use The cost of a penny weight of pure gold is currently $79.53. The cost of a penny weight of pure palladium is $130.6. It used to be that palladium was added instead of gold to the precious metals often used for pfms, but now laboratories are finding that palladium is no longer affordable. The lab that I am using has just changed the formulation of the metal it's using to one that has more gold than palladium. I really do not mind, but metals with more gold are softer and often easier for a dentist to accidentally polish off delicate margins. It is important when polishing "higher gold" formulations to exert less hand pressure when performing the final polishing of the crown's margins. Other wise there should be no problem with this change. Traditionally labs have chosen alloys with higher gold percentages for optimal esthetics, since alloys with higher concentrations of

Tongue Ties: What Parents Need to Know

Image
For a long time, people just didn’t seem to know much about tongue ties. In the early years of my practice, few of my patients had ever heard of a tongue tie. When I pointed out that they or their children might be tongue tied, I was often the very first practitioner who’d mentioned it to them. When I told them that a tongue tie might actually be the root cause of their oral myofunctional issues, or even their sleep apnea , I’m sure that some of them thought I was crazy. But in the last few years, things have changed so much! Initially, there was a small increase in the number of patients who were contacting me specifically about tongue ties. Dentists and orthodontists also began reaching out more frequently to discuss the application of myofunctional therapy exercises to tongue tie treatment. But in the last year or so, that little bit of interest has become a surge of awareness. Tongue ties and their effects on health and craniofacial development are finally becoming mainstream.
