  • CBCT planning and guided surgery will save you money by decreasing the time needed for surgery, making your surgeries more precise, decreasing the need for lots of inventory, and making your restorative costs more predictable.
  • CBCT planning and guided surgery will make you more money through increased case acceptance, more referrals, giving you confidence to tackle more cases, and by helping determine which cases will be complicated and/or less profitable

Which Implants To Use

Everyone’s titanium integrates……. some just integrate much cheaper!

  • Use a value branded implants with a good track record like Blue Sky Bio (my favorite)
  • Use a conical connection with a platform switch
  • Use implants with aggressive threading

Reduce Your Risks:  Failures are the Kiss of Death

  • Flap everything you can and bury the implants with primary closure in a 2 stage approach.
  • Flap rather than punch at uncover to gain keratinized gingival by rolling it to the buccal
  • Avoid immediate placement until you’re very experienced.  I suggest grafting all sites with                 Maxxues 50:50 Mineralized/Demineralized FDBA ($51 for 0.5cc) mixed with Fusion Bone Binder (Woodland Hills Pharmacy) and covered with a collaplug in single rooted teeth or a Cytoplast TXT-200 Nonresorbable membranes ($40) in molar sockets
  • Stick with shorter implants (8 and 10mm lengths).  There’s almost no value in a longer implant unless primary stability is of the utmost importance (ie immediate and single staged implants which you’re not going to do…… right!?
  • Stay 2-3 mm from anything with a name (inferior alveolar canal, mental foramen, etc)

Tips to do More Implants

  • Learn to do conservative crestal sinus lifts. 30% of all potential implant sites you encounter will need a sinus bump or a sinus lift.
  • Buy a CBCT.  Having to refer out for scans creates a much bigger barrier than you realize.  Most dentists find that the number of implants they do doubles once they get CBCT in office.
  • Plan cases in front of the patient.  The purpose is twofold:  you will be able to confidently tell them whether you can do the case and what it will cost right then and there.  It also creates a significant “wow factor” when your patients see you using this level of technology and planning.
  • Lower your prices.  Price is your gas pedal.  If you want to do more, step on the gas and lower fees.  A routine single tooth placed guided takes me an average of 2 hours total time and 3 appointments from start to finish.  Even by charging a bundle fee of $2500, you’ll still generate over $1,000 an hour.
  • Offer in house financing:  Implants are perfect for financing since they won’t get the final product for several months after starting the process.  Not staying current with payments? No implant crown for you!

SLA vs FFF / FDM workflow and space requirements

By | Education, Healthcare, Materials, News | No Comments

SLA (Stereolithography ) is often compared to the FFF (Fused Filament Fabrication) / FDM (Fused Deposition Modelling) process of 3D printing and always shows very impressive results. The detail level is far superior for SLA but there are a lot of complications to the process. Due to the huge numbers of dentists, dental labs and orthodontists contacting us recently I thought I would share some of what I have learned.

The most common comparison is the strength of the parts created from resin vs those created with fused filament which always comes out on top. Next are the many resin handling issues which make filament printers much easier and safer to use.

It is easy to discount FFF/FDM completely by just looking at pictures of the excellent smoothness of an SLA print vs an FDM print. The SLA process can create a smoother and more detailed surface finish and and can create a fully solid, partially transparent part which is difficult to achieve on FFF /FDM machines without post processing. This makes it harder for those of us demonstrating fused filament fabrication printers to keep a viewers attention.

To someone viewing the printed results of 2 models side by side it would be hard to choose the FFF / FDM print if visual quality or surface detail was the goal. In a comparison of useability which requires strength, the FFF /FDM print is far more likely to come out on top particularly due to the huge selection of material types available. The SLA materials tend to be closely linked to specific printers, it is unlikely a 3rd party resin will be allowed or compatible. This limits the SLA user to the resins developed by that manufacturer. In a comparison of workflow the SLA process is quite scary, warning labels and notes on resin handling and cleanup dominate but the consumption of core components of the SLA printer along with litres at a time of IPA (Isopropyl alcohol) and the expensive resin is certainly worth exploring before any decision is made to exclude filament printing. The accuracy of the two methods should theoretically be the same but I have yet to see an SLA print which has been perfectly dimensionally accurate while my Robox is within 0.01mm in all axes without my input all day every day. Cost comparisons are far further apart than the price of the printers would suggest. SLA resin cost is high, plastic filament cost is low. This expensive resin is wasted with every print, plastic filament is only extruded as required. This cost in particular is not shown in “part cost comparisons”, nor is the very wasteful rinsing in IPA to remove excess resin following a print or the cost of the consumable resin carrying and curing parts, or the disposal and storage as well as low shelf life for expensive SLA resins. Oh and the space required for SLA printing is rarely mentioned, you really need a spare room and some strict policies to control the spread of sticky resin the smell and the harm to the environment.

In the chart below I’ve listed some positives and negatives of each method along with typical usage and costs. Blue indicates the best in my opinion for each row. I obviously support filament printers in this, perhaps your comments can sway my opinion?

FDM SLA
Limited detail, high accuracy, layer lines visible High detail and accuracy, layer lines hard to see in some cases
Parts and excess material can be disposed of in regular waste Resin waste and printed parts require special disposal. H413: May cause long-lasting harmful effects to aquatic life
No material wasted except with support creation, no mess Wasted resin is washed away in IPA and disposed of regularly in build tank, sticky residue from resin spreads around work area and is hard to clean. Disposal of cleaning products restricted
No use by date on filament with low cost 12 month shelf life and high cost
Material is inert and harmless before and after printing Requires special handling equipment
Can be used in any work area Requires special work area
Materials are widely available and cross compatible Only specified resins can be used with most SLA printers
Minimal requirements for storage of material Requires special storage conditions for resins and required cleaning chemicals in large quantities
No additional equipment Cleaning baths, UV Light booth, safety, storage and disposal equipment
Minimal space required to function Considerable space requirement to keep several large pieces of equipment away from other equipment and work areas
Range of materials in many colours and with a huge range of mechanical properties Very limited range of materials, locked to manufacturer
Opaque parts unless post processed Optical clarity in some materials
Material dependant useable indefinitely  Low shelf life of parts due to UV exposure
Low cost of consumable parts High cost of consumable parts
Material cost is low $25 per kg Material cost is high $99 per kg + processing and waste!
Medium flexural strength  (material relevant to medical use) Low flexural strength (material relevant to medical use)
Low upfront equipment cost High upfront equipment cost, printer and additional equipment
Potential for dual material with dissolvable or peel away support Single material with mechanical removal of support
System allows dual material for overmolded parts and pause features for inserting captive objects No system for inserted or overmolded parts
No training required for use or handling High level of materials handling trainingrequired

 

My conclusion is this:

SLA is not a threat to FFF / FDM printing, if anything the 2 methods can work side by side as their benefits do not overlap. Personally I would not let the resin (or the smell of it) near my home or my family but if I had a dedicated space within a business and the training and staff to run this then I would consider SLA as an addition to several far lower priced FFF /FDM printers. I could print many iterations of a design on the filament printers and perhaps a surface model on the SLA machine once the design was final, actually it might be best to just outsource that part…

SLA should remain in the hands of professional labs or dedicated service providers, FFF /FDM is for everyone. In fact with the low cost of filament printers, every designer should have one on their desk.

The Ferguson Technique – Dental implants using 3D printed surgical guides

By | Design, Healthcare, News | No Comments

Dr Rick Ferguson DMD presents a webinar hosted by Michael Saltzman, Director of Guided Surgery from Blue Sky Bio.

Dr. Ferguson is a Diplomat of the ICOI, Associate Fellow of the AAID, Clinical Assistant Professor University of Florida. He has lectured nationally and internationally He teaches live surgery and is a visiting lecturer at the University of Miami GPR Program. He has a full time private practice in Davie, FL. His course in dental implants can be viewed on his website here http://www.implanteducators.com/index.php/courses/3d-course

Dr Ferguson gives a brief look at previous guided surgery techniques and guides and compares them to the current method he uses and teaches in using 3D printed surgical guides. Rick describes the development of his technique which enables in practice low cost guided surgery.

Several cases are presented during this webinar including each stage of the workflow for each case, reasoning and options, costs and alternatives. Please note that case documentation includes 3D scans of bones as well as photos and video of guided surgery taking place which is quite graphic, the information presented is more suited to dentists than patients.

Examples of workflows in past high cost methods and current low cost 3D printed guides. Dr Ferguson shows examples using Robox and provides comparisons to Form2 DentalSG workflows and printed surgical guides.

The free software Dr Ferguson uses in this video can be found in the links below:

You can buy a Robox as used by Dr Ferguson directly from Blue Sky Bio’s US website (select United States from the dropdown on their site) https://blueskybio.com/store/cel-robox or from a Robox reseller closer to you www.cel-robox.com/where-to-buy/. The material used to print surgical guides with Robox is nGen by Dutch company Colorfabb, you can buy this from Robox resellers on Robox SmartReels. Robox does allow printing with materials from other suppliers and the range of materials available on SmartReels is constantly being updated.

Back in stock!…..oh wait, no, sold out again…

So we had a shipment delivered…but…they are all going out again over the next 2 days, none left at CEL-UK. You can still buy from our resellers http://www.cel-robox.com/where-to-buy/

wheretobuy160504pt

I think it might be the schools buying them all, maybe dentists, maybe both….oh no, maybe it is DENTAL SCHOOLS!

We are making more. If this keeps up we might need to cancel warehouse leave…or get the engineers to do some physical labour 😀

Some tips for a successful video:

  • Gaps and pauses are fine, don’t rush. A short answer to the point is much more likely to be used. The whole edited video will be made up of short, relevant responses.
  • Good sound is important, turn off fans where possible and move the microphone close to your mouth, test the sound before starting.
  • More light will improve most video recordings, use the highest resolution possible, the resolution is not critical but we do want to see your face (or an entertaining stand in).
  • Be positive! Be happy! Smile at the start of a response and sit up straight.

Conditions:

  • Pete will decide everything. Pete will have the final say. Pete’s decision will be final unless he changes his mind. No guarantee of compensation, reward, payment or credit is offered, nor will it be provided for any video.
  • Entries must be posted here in our forum with a link but can be uploaded to any video streaming service.
