Missing Teeth Replaced with Mini Dental Implants & Porcelain Crowns ~ A technique from the Advanced CE Seminar

This is part II of the post Mini Dental Implants to replace a missing front upper tooth.  See recent posts for the history of the case.

Missing teeth    Minis in

Its been 4 weeks or so and the all Porcelain crowns are back from First Impressions Dental Lab to fit over the ACE Secure Mini Dental Implants.

A scan was taken of the mini dental implants with a iTERO digital optical scanner and Jon Younce at the lab was able to plan the case in a all digital format to make Zirconium all porcelain crowns.

These crowns could be made over any mini dental implant (Intra Lock, IMTEC, OCO Biomedical mini, Hiossen etc…) 

I have often been told that it is not possible to make good looking anterior(front) tooth crowns on top of mini dental implants because of the ridge lap design.  Or without creating a emergence profile below the gum its not possible. 

Crowns over mini dental implants

 

I think the real issue is the patients gum thickness.  If the gum is too thin you see the gray halo of the implant as it comes out of the gum.  Even if you have a traditional implant with a two piece design and a custom fabricated ceramic abutment if the gum is too thin its hard to have room for the crown. 

So I like to have patients know before we place the mini dental implants if they have thin tissue type and what can be done to make the gum thicker if aesthetics is a primary concern. 

As with anything in dentistry….almost everything is possible…..its just how much time, money and effort the patient and doctor are willing to invest.

Frequently Asked Questions on Mini Dental Implants ~ Do They Work?

Mini Dental Implants ~ Are they bad? Do they work? Can you unscrew them with your fingers? Do the break? Can you use a mini implant on the upper arch?  And many more……

I get lots of questions from Dentists and Patients alike on Mini Dental Implants.  The short answer is if used and placed properly Mini Dental Implants will work to solve the patients request….to have a 2nd chance for teeth.  A mini dental implant just does it a different way.  Do I think mini implants will replace traditional regular conventional implants?  No….mini dental implants offer the patient another choice.  There will always be a need for regular implants.

Do Mini Dental Implants Work?

Yes…they can replace missing teeth in the upper and lower jaws with porcelain crowns or bridges.  They can hold in upper or lower dentures with a o-ball and a snap fitted into the denture.  Mini Dental Implants have a history of working well for over 15 years.

My Dentist tells me that I should not get Mini Dental Implants; what should I do?

There is lots of confusion on this subject of mini dental implants vs. regular traditional implants.  There should not be.  They both work and they both work well.  It's more of an issue of choice for the patient.  If a patient does not choose regular traditional implants they should not be told to just go home; they should have been offered mini dental implants.  With 40 – 50 Million Americans without teeth, implant treatment should not be only for the rich.  Mini Dental Implants offer what was once not possible for most patients.  With only 3% of Americans with Dental Implants we as Dentists have so much work to do.   It would take us our entire careers to help everyone live a better life with dental implants. 

Mini Dental Implants do integrate (bond) to the bone. 

They are approved to use in the USA by the FDA for long term use anywhere in the mouth.

I can tell you that my success after placing over 1500 mini implants is the same as regular conventional dental implants.  I encourage patients who have reservations to make a consultation with a skilled Dentists (Oral Surgeon, Periodontists, or General Dentist) who places traditional implants and a Dentist who places mini dental implants.  I would ask each one to see examples of their final results and how many implants they have placed.  With that information I think patients are well equiped to make a choice that is appropriate for them. 

Mini Dental Implants are so small, will they holdup in my mouth?  I was told they would break.

Mini Dental Implants are made from titanium alloy.  This alloy is 1.6 x stronger than CP(Commercially Pure) Titanium.  Most mini dental implants are between 2.0mm and 3.0mm in size and fracture LESS because they are SOLID.  A regular conventional implant is two pieces that is held together with a screw.  If the traditional implant on average is 4.0mm wide and the screw hole in the center is 2.0mm wide then the outer wall of the implant is at most 1.0mm.  Because of the one piece design the mini dental implant will fracture less than a regular traditional implant.

Do Mini Dental Implants integrate or bond to the bone?  I was told they do not.

All the mini dental implants we use are made from the same Titanium alloy used in making the larger regular style traditional implant.  The surface coatings are the exact same, so if titanium integrates (bonds) with the bone, the same will happen with a mini dental implant.  Studies now show this to be true.

Mini Dental Implants to replace a Missing Front Upper Tooth

Our next patient was missing one of his front teeth….well actually he is missing a few of his teeth.  However our plan is to replace these missing upper teeth with mini dental implants and crowns a few at a time as he can afford to do so.

He has an upper plastic partial denture plate.  We will remove the plastic denture teeth as the crowns and mini dental implants are added.

Upper Partial or Mini Dental Implant Bridge?

It seems here lately we have had a lot of patients come in that are unhappy, frustrated and just don't like their partial dentures.  They specifically want to just get rid of it and replace it with some mini dental implants and a set of porcelain crowns or porcelain bridges. 

Existing upper partial

 

Photo of my patients existing upper partial denture that replaces most of her upper front teeth.  I did not think it looked all that bad for being 7 years old….she just did not like it.  The way it kept her from tasting her food, the way she talked with it, the bulk of metal as she put it on the roof of her mouth.  She also did not like the lower but wanted to start with replacing the top partial plate with mini dental implants and a bridge.

 

Ridge before mini

 

Like most patients that seem to find me…she had what looked at initial glance good bone.  However on the x-ray it was mostly tissue.  It had just been too long since the teeth had been extracted and the bone had just melted away.  Without roots the body over time just starts taking away the bone.  If an ill fitting partial sits and rubs on the bone year after year it accelerates the process of bone resorption.

 

So we went over the options as usual of traditional implants and some bone augmentation or I could use what bone she had, place at least 6 minis and make her a 8 tooth bridge to replace her missing teeth. 

Partial

 

I used her existing upper partial denture plate as a guide on where I could place the mini dental implants.  I drilled a hole in the center of each tooth, placed in back in her mouth and with a marking stick located the ideal place for the mini implant. 

 

 

 

Of course in her mouth most of the 'ideal' locations had less than ideal bone. 

 

Post mini

 

 Photo of 6 mini dental implants placed day of.  You can see 2 areas where we tried to get the last 2 mini dental implants in but found poor bone.  These areas will just fill back in with gum tissue. 

 

 

A impression was taken of the mini dental implants and off to First Impressions Dental Lab for them to make the 8 tooth porcelain bridge.  In three weeks her mini dental implant bridge will be back and I will post the photos.

Mini Dental Implants to Secure a Lower Partial

The uses for a mini dental implant never stop amazing me.  Today we had a fella come in who had broken his lower little front tooth.  Broken lower front tooth

 

Clinical photo of the broken lower front tooth….it was broken below the level of the gum tissue.

 

 

 

So I decided to extract the root tip for him with some peritomes to save as much bone on the lip side as possible to hold our ?????  You guessed it, a mini dental implant.

Our goal is to add a few more mini dental implants over time and then get rid of his lower partial denture for either a full set of fixed crowns or a secure lower denture.  At the end of the procedure our patient commented on how quick and painless the entire process had been.  It nice that such new products exist for us as dentists to offer such a non invasive, non surgical approach to dental implants.

Mini Dental Implants ~ Extractions ~ Immediate Placement and Saving the Bone

Another good use for mini dental implants is when we have a failing bridge or a tooth that has had a failing root canal treatment.  Our next case is a patient that came to see us after having pain with her temporary bridge.  Her old bridge she told me was wobbling around and her dentist told her the post was weak and he needed to make the bridge longer…..only if we had met sooner that might not have been what she had chose to do. G8PBAUAAQB92

Failing RCT bridge

 

We can see on this x-ray (this is the x-ray she brought from her previous dentist before he removed the bridge and made it one tooth longer)the decay under the post that continues down the root on the tooth that has had the root canal treatment.  The root canal tooth was very mobile (as in when I took the bridge off to assess the teeth I could move the root in the bone. 

 

We covered all the options with the patient from a new bridge(her previous dentist has already made the decision to make a longer bridge for her that went to the canine tooth in front of the root canal tooth).  I told her I thought it would not be a good idea to keep the root canal tooth since is was already mobile. 

We talked about 2 traditional implants, or a few minis and single crowns on her natural teeth. 

Extraction

 

She decided to let me extract the Root canal tooth.  There was enough destruction of bone on the cheek side that I explained to her that I would place some socket preservation material (a freezed dried mixture of bone) in the hole where the root was to help her body fill in that hole with good live bone so we could come back in 12 weeks and place a mini dental implant.

 

 

Bone graft

Here we have the socket preservation material in the extraction site.  Its easy to see how plump the ridge looks.  It will stay that way without caving in and will give us lots of good bone to put a mini dental implant.

I will continue the post with the pictures of the crowns when we get the final mini dental implant in place and the crowns back from the lab.

Secure Mini Dental Implants~A System to solve most dental problems

Mini Dental Implants were originally used to Secure  lower dentures….but they can be used for much more.  From replacing a single missing tooth to replacing several missing teeth to a full arch of missing teeth with a fixed porcelain bridge. 

Mini Implants ranging in size from  1.8mm~2.0~2.3mm~2.5mm~up to 2.9mm.  Anything over 3.0mm gets in my mind into the traditional implant range. Some people will state that 3.25mm is the cutoff for a conventional implant to secure a 2 piece abutment system. 

To Secure a lower set of crowns on our next patient we used traditional implants to do the All on 5 concept. 

New Picture (1)

Post Implant Pan x-ray with 5 implants in place that will Secure the lower fixed porcelain crowns

 

 

 

 

 

Clinical photo day of surgery…full flap was made to find both mental nerve bundles.  The lower ridge had to be surgically made wider to accomodate a larger traditional size implant.  You can see from the photo the level of surgical skill needed to due such surgery.  It is quite different than placing a mini dental implant.  It takes a very talented dentist to do this kind of surgery on a daily basis.  I commend and compliment any dentist that takes the time to offer this kind of implant dentistry.  Although I did this case and several more; I question myself each time….could I have offered a different solution that would not have required so much from my patient? 

 

New Picture

 

 

 

 

 

 

 

The mini dental implant solution to Secure a lower set of crowns would be 8-12 of them.  With that much surface area the minis have the ability to absorb the force of chewing and can equally distribue that force over the entire lower jaw. 

New Picture (2)  
This case illustrates how we can Secure with Mini Dental Implants a lower set of Porcelain crowns.  As you can see from x-ray there would have not been room for a larger traditional implant without additional surgery.  That surgery would have been to flatten the ridge of bone or to lay a full flap similar to the prior picture and expand the bone.  Both would increase the cost to the patient….in terms of $$ and healing.  I have done this same concept on the upper arch as well to replace a denture plate with fixed crowns. 

 

 

To review, Mini Dental Implants do not replace the need for Conventional or Regular Implants….they just offer the patient another choice in their dental treatment.  Technology has made it possible to make a smaller implant out of the same dental alloy with the same surface coating as a larger implant at a reduced cost.  With this we now as Dentists should offer our patients ALL the choices from doing nothing and letting millions of patients suffer with missing teeth, to traditional implants that have the longest track history of success to mini dental implants that have over 15 years of success.

Mini Dental Implants to Replace an Upper Partial Denture Plate

This is actually a case that was done last year.  My patient came in for his 6 month cleaning about 6 months late….  Not what I like for patients to do.  But he was certainly not the ideal patient and I explained that to him prior to committing my time, energy and mini implants to the case.  He is a heavy smoker (around 2 packs a day).  A big NO NO for traditional implants or any kind of implants in general.  But I told him if I could get the mini's in without having to flap his gum away from the bone the implants would have a better chance of healing. He had seen another dentist about traditional or conventional implants but could not move forward with treatment due to the cost.  A familiar story.  I told him we could offer another choice…the mini implant choice.  Not the same solution but a different solution that might work for him.   He had a upper partial to replace his missing 6 front teeth.  He had an accident over 10 years ago and had been wearing a cast metal partial that he did not like.  His big complaint was the metal hooks and just the bulk of it.  He did not really have a complaint on the way his front teeth looked on the partial plate.

Overall I am happy.  I know he is happy.  I think his comment was, 'Doc now that I got my show teeth do I really need to get the rest of them fixed?'  How do you answer that question as a Dentist?

Now if I could just get him to quit smoking, come in when he is required to for his cleanings and move forward with fixing the rest of his teeth…..  But as they say, Rome was not built in a day so we move forward one MINI step at a time.

Mini Dental Implants ~What I use them for ~Just about anywhere in the mouth

Mini Dental Implants have a wide variety of uses.  I find more and more uses for this as a General Dentist.  I think in a matter of time mini implant dentistry will become everyday dentistry.  As routine as getting a filling.

 

Minis lowers

 

Mini Dental Implants in the lower jaw.  With 4 mini implants in place you can secure a lower denture.  Even with a thin ridge most of the time these can be placed without cutting the gum.  If the gum is not cut then no blood supply to the bone is disrupted.  The bone heals faster around the mini implants allowing the patient to function with a implant retained denture immediately.

 

Minis upper denture

Mini Dental implants in the upper jaw.  The upper jaw bone is softer and not as dense as the lower jaw.  With 6 mini implants in place you can secure an upper denture.  With a good well made denture that covers the hard bone at the very end of the upper arch (maxillary tuberosity) you can remove the middle of the denture. Most patients appreciate the palate of the denture being removed.  With this horseshoe shape design patients can taste food better, have better speech, decrease in gagging and less bulk of plastic.   With more implants sometimes it is hard for patients to 'line up' all the o-balls and housings in the denture.  What I would like as a dentist is if someone would make a Zest Locator mini dental implant.  The Zest Locator is the 'gold standard' in attachments for the traditional or conventional implants.  It is much smaller in height and guides the patients denture into the retentive rings.  The retention rings are also made of nylon so the rings last much longer than the rubber ring used in the o-ball attachment.  Right now OCO Biomedical i- mini and i-micro implants, IMTEC MDI, and Intra Lock mini implants all use the o-ball with no locator attachment available. 

Locators

 

Zest Locator attachments with metal housings shown in picture.  You can see how close to the gum they are.  Increase in patient comfort, less vertical and horizontal stress to the implants due to less of a lever arm. 

 Locator image

Image of the Zest Locator implant attachment.  You can see the 'flat' top surface.  The male snap that fits on the outside and inside of the Zest Locator acts as a guide for ease of inserting the denture.  When you have multiple mini implants this would be a welcome advantage.

With just a few mini implants you can take a lower partial denture and remove the metal clasp, fit the retention housing in the partial denture and now the patient does not have any visible metal on their teeth.  If the partial is well made and has proper stops in the back of the lower jaw (retromolar pad) the partial will not settle and the implants will not get overstressed.

Once again even with a few of these minis you can make a case that works.  Over time if the patient's desires change and they want to add more its always possible.

Retention of Fixed Bridges

In this case multiple teeth were failing and mini dental implants were placed the day of extraction to support a acrylic temporary bridge made in our dental lab.  I used some pink acrylic around the front teeth to help hide the extraction sites while they were healing.  A final porcelain bridge was made to fit over the mini dental implants once all the gums heal.  This case is now been in function for over two years.

Academy of Mini Dental Implants First Journal

Many thanks to Dr. Bob Caseldine for getting the first edition of the Journal of the Academy of Mini Dental Implants published. For him it has been a labor of love and it shows.  Great Job!  With this new addition to the Academy I hope it encourages more Dentists to see the value that the mini dental implant has to offer for our patients who all too often suffer from ill fitting dentures and missing teeth.  Without these mini implants I just do not see how we can help so many patients who think there is no other option except to stay at home and suffer.
