DentalBridge1 300x196 FEM for dentists: An easy to use FEM software tool for the biomechanical analysis of the interaction between single dental implants and the jaw bone

 

 

 

 

 

 

 

An “ease-of-use” concept that allows a dentist to perform a patient-specific Finite Element Method (FEM) simulation of the implant – jaw bone interaction is presented.

One reason for implant failure can be exceeding strains in the jaw bone which are induced by the implant’s loading. High strains in the jaw bone for example can lead to a crestal bone loss. Depending on the implant geometry (length, diameter) and the patient-specific jaw bone geometry the biomechanical stressing of the bone tissue is influenced. A well-chosen implant can reduce the loading of the jaw bone and can reduce the risk of implant failure and vice versa.

However, the choice of the implant geometry is typically based on the experience of the dentist and no mechanical issues are considered.

Using the presented concept the dentist can virtually test various implant geometries against each other before the operation is done. This allows him to find in terms of biomechanics the best suited implant. Or, especially in critical situations (low amount of bone) he can judge whether the chosen implant exceeds the allowable stressing.

    Treat your dental suppliers professionally

    Who are your top suppliers? Who are you writing a significant check to each month? Take a look at your credit card statement and business checking account and make a list of your top 10 dental vendors. One of the principles of the national Baldrige award (http://www.nist.gov/baldrige/) is to develop a long term win-win relationship with your “key suppliers/partners and collaborators”. They ask questions such as: What role do these suppliers play in delivering your services to patients? How do [...]

    Great book for parenting: NurtureShock

    Although I normally write about dentistry and business management, I just finished a great book that shares unique insights into children – and for every dentist, hygienist, assistant and office manager raising children – I hope this is helpful. The authors, Po Bronson and Ashley Merryman, are journalists who realized that over the last 10 years there had been some revolutionary scientific research on children that might affect the way people parent. However, this great research was shared in 5 [...]

    Are you leaving money on the table? Submit your full fee to dental insurance

    Dentists agree – dental insurance is a necessary evil. Necessary to help fill schedules since we’re all trained (thanks to health insurance) that we must follow our insurance plan. Evil because it almost physically hurts to write off 15% – 40% of our fees. We all know that we’re taking a huge hit thanks to dental insurance, but are we also leaving money on the table that’s our own fault? Depending upon your set up for submitting claims to dental [...]

    Have you integrated your faith into your work?

    I recently attended the University of Dayton’s Faith at Work breakfast event – sponsored by the Center for the Integration of Faith and Work in the School of Business. Our speaker shared his ‘pilgrimage’ with faith and work. Influenced by his Catholic father who assembled headlights for Chrysler, he went on to teach in a Catholic school and later created a company that provided job training for displaced workers – particularly those from the manufacturing sector. He came to see his [...]

    How the Dentrix appointment history paints an accurate picture

    Here is an actual email I received a few weeks ago from a long term patient: My husband had an appt on 2/7. He’s been away on business since 1/4 and when we realized that he would not be back until after 2/7, I called and rescheduled his appt. I called on Jan 25. I had joined him on his trip the day before. It was rescheduled for March 6 at 8:30 am. I do not know who I talked [...]

    Dental politics: Do you know the scoop?

    Every year our state dental association hosts a “Day at the Statehouse” where dentists are invited to spend a day learning the top legislative issues in dentistry – and then to share these topics with their state senator and representative. The dental association staff provides written materials to the dentists that clearly explain the 2-3 hot topics for that year. These talking points guide the individual meeting between the dentist and his/her legislators. When a dentist registers for this Statehouse [...]

    What I learned at Chicago Midwinter Part 2

    A dental office manager’s perspective Here are the rest of the ideas I picked up at the show: CareCredit updates – Always nice to meet with these reps who show us our applications and credit used in our practice last year, plus, when you spend the time to review this information, they give you a special gift. This year it was a pillow pet – which we took home & gave to our pediatric dentist, of course! Colgate rules change [...]

    What I learned at Chicago Midwinter

    A dental office manager’s perspective With an entire showroom floor full of clinical products and equipment, why would a dental office manager attend a dental tradeshow like the Chicago Midwinter? Here are the ideas I learned at the show: Dentrix updates – Since we use Dentrix practice management software and I know Dentrix brings their best trainers to the show, I always stop by their booth to ask what’s new and ask specific questions. This year I learned a trick with their [...]
