NEW DENTAL ARTICLE BY Dr. Walford PUBLISHED IN ORAL HEALTH JOURNAL

A new article In Canada’s premiere Dental Journal, Oral Health Journal, written  by Dr. Walford about the selection of Dental Composite Resins has been published in the December 2022 Issue at the following link https://www.oralhealthgroup.com/edition/2022-12/

The article is titled: “Why we Need a QR Resin Code When Choosing a Resin for Longevity and Clinical Effectiveness” and give your brain some work to do!

THE DENTAL BUS CLINIC IS CLOSING

Dear Patients.

After 37 years, the dental bus is closing down, and Dr. Walford will be ceasing clinical practice.  A list of practices that can take new patients is now on  this page. Hopefully  This will reduce the amount of time you will need to find a new practice to call home.

To all who have been with us over these years, a heartfelt thanks for your loyalty and appreciation! We have been the object of much love for the last few months as we have been saying our goodbyes. I can think of no other place I would rather have practiced than here.

The dental bus will remain for sale for another 12 months in the hope it can remain on Hornby Island, its birthplace, and be reactivated.. If you know of a dentist who wants to change to a lifestyle on a Gulf Island, send them our way, at pwalford@telus.net

HOW TO HAVE YOUR RECORDS SENT TO A NEW DENTAL OFFICE.

Please have your new office request records and x-rays at dr.peterwalford@gmail.com This email will be reviewed weekly by ongoing personnel and it will take another week to arrive as hard copy by mail. There is no charge for this service.

HOW TO FIND A NEW DENTIST

One of the best ways to find yourself a good dentist  is to ask your friends who they have been happy with. This gives you an inside look at the  office atmosphere, policies, quality of care, and other concerns you will want to know about before booking.

However, in no particular order, here is a list of dental offices that are accepting new patients in the Comox Valley. If the office you want is not listed here, they may have advised me in my research that they are at capacity, but perhaps they  will make an exception for friends or family of a patient already in their care.

However, this list will hopefully save you a lot of frustrating legwork in calling practices that are already full.

In this list, when a name precedes the clinic name, it means that it is a proprietorship. and you are likely to see just one dentist.

If it is listed as a clinic, it will likely mean that it is corporate, or that it has multiple associates, and you may not always have treatment with the dentist who examines you. Be sure to ask about that if it is important to you.

PLASTIC-FREE COVID COMPLIANCE

Last week we changed the last protocol in our Covid compliance to being fully plastic-free.

Living on an abundant ocean’s edge, as I do,and having seen one too many videos of albatross chicks dying of ingested plastic, as I have, I just couldn’t accept that the only way to manage transmission is through single-use disposable plastic barriers.

All our barriers are now washable. Our wipes are washable, up to 300 times, and ultimately compostable. We know that Covid dies in the dryer at 135 degrees F, so our measures agree with science. As I can I will post pictures and more details so that you can see for yourself. And yes, it is much much cheaper, not only  omitting the cost of purchase, but also for tipping fees for increased bulk in the waste stream. And therefore eliminating another cost to pass on to patients.

Do we get to forget the environment because we have a human pandemic crisis? Obviously, if you think that,  you have never considered being an albatross.

NEW ARTICLE PUBLISHED IN ORAL HEALTH: “GUIDED ANTERIOR REHABILITATION IN COMPOSITE RESIN”

An article in Oral health Journal written by Dr. Walford  is now posted online. See the online article

The title is “Anterior composite rehabilitation: a minimally invasive approach.”  . It details a method for augmenting worn anterior teeth from articulator-mounted models, using a stent to arrive at a pre-determined clinical outcome.

This article closely follows the content which will be organized in the upcoming Handbook of  Composite Prosthodontics

JOIN THE BANDBENDER COGNOSCENTI

At the Pacific Dental Conference  in Vancouver on March 8, 2019 , Dr. Walford demonstrated a lower-arch  molar MODL restoration on the Live Stage in the Exhibit hall. The Bandbender™ was an key part of the procedure. A large number of attendees “got it” and placed orders for Bandbenders with Sure Dental Innovations, our dealer for Bandbenders™.

Haven’t heard of the Bandbender? It’s the game-changing matrtix-shaper that makes large composites successful. Without it, don’t pass go, don’t collect $200.When sectionals become useless, bring out the Bandbender™.

You can’t talk about flight if you haven’t got wings. The Bandbender shaping system is a cornerstone to large composite success. It develops properly curved proximals from a flat  typical Tofflemire matrix. No broken contacts, no food traps, no expensive repairs. Win every time. Restore boxes of any size on teeth with any amount of missing tooth structure.

It could bring an enormous improvement in your restorative capability and your practice satisfaction. Stop doing it the hard way.

OMNICHROMA – A PROMISING NEW RESIN

After development in offshore markets, Tokuyama launched a new resin at the prestigious Chicago Midwinter Meeting in February 2019. It also hit the Pacific Dental Conference, March 2019 . The resin is Omnichroma

What’s new? Its singular claim is an ability to blend with very wide range of tooth shades using only a single shade. They manufacture a second to mask/opaque where needed.

See Cases restored using Omnichroma 

The Promising aspect of this product: Universal shade match promises to simplify  inventory for both dentists and suppliers. it also might improve cosmetics for the patient. Also, it might solve an unmet clinical problem-shade mismatch between restorations and teeth  if teeth are whitened (bleached) through a peroxide program, office-provided or OTC .

How good is it? Can we buy it, throw away our other shaded resins, and put it everywhere? We can evaluate esthetics because we can see that. Esthetics are not enough. We need to also evaluate any new resin for properties which we cannot see. Unless you feel like being reckless you will have to address the limitations highlighted in black below. take your own look at physical properties, which are housed in this product at Tokuyama’s Omnichroma Technical Bulletin

Check it out. You  will find  graphic comparisons with other well-known resins from several university research labs on:

  • Gloss -pg 18= >90%,  rates very high compared to most resins
  • Wear resistance – pg 20= negligible with negligible opposing tooth wear. Top in its class
  • Polymerization Shrinkage – pg 21 1.5% a beneficially low number
  • Radiopacity – pg 25 = average for posterior resins
  • Contraction Stress – pg 29 =>2.5MPa, higher than most, a negative quality suggesting careful placement of small increments might be needed to avoid white line defects and crazing enamel in the host tooth
  • Flexural Strength —pg 30- 110MP  weak– suitable for light function patients in Class II restorations
  • Elastic Modulus- pg 30= 9.2 GPa- less than dentin, below median for posterior resins, limiting its application to light to light-medium function patients. See Resin Selection Sieve , Light function patients 
  • Compressive strength -pg31- 310MPa = high, but not usually a significant clinical attribute
  • Depth of cure – pg 32 –  consistent to 4 mm, indicating high curabiity, which should deliver on properties in real-life clinical application. Better than most resins
  • Stain resistance -pg 22 = low, on par with best-rated resins
  • Color Matching- repeatedly superior to most shade-matched resins
