Screw Retained Or Cemented Dental Implant Abutments….Which Is Better?

This is actually a really old topic that has become renewed again in the last few years. Do you hold your implant crown or bridge in with a screw abutment connection or do you hold it in with cement? Each technique has their merits.

In this video I will describe many of the reasons why one should be chosen over the other. There seems to be a very large educational gap in dentists that are heavily involved with implants and those that just dabble in dental implant restorations. Some people take an all or none approach with regards to screw retained crowns or cement retained crowns but did not really seem to understand the biomechanical principles in relationship to bone physiology.  The same educational gap holds true for connecting implants together or leaving them as individuals. I hope this helps you make a good decision on how to determine what is best for your unique situation. I have utilized both methods for almost two decades now.

Patient Review: Full Upper Dental Implants with a Fixed Prettau Bridge

Are you interested in dental implants? See what one patient (who traveled all the way from Michigan to California for her procedure) has to say after receiving full mouth upper and lower dental implants with a fixed Prettau bridges from Dr. Ramsey Amin.

If you are looking to replace all of your teeth with dental implants, please hear with this patient has to say about her experience with Ramsey Amin DDS.

Full Arch All on 4, 5, 6, 7, 8 Implants – 3D Lab Teeth Design Video

This is a great video explanation of full arch zirconia Prettau style dental implant bridges made for the All on 4, 5, 6, 7, 8 etc. procedures.  These are full jaw situations.  In this video I narrate the actual lab design of how the teeth are made.  Buyer beware!  Not all teeth are created equal!  Experience is everything when it comes to designing the teeth.  In this case the upper is an “All on 6” while the lower is an “All on 5” totaling eleven dental implants.
Every single day I get comments, calls and patients in my office that have had these procedures done.  Although the implants have integrated the bridges have failed, broken or they are so ugly and bulky that the patient hates them.  Fabrication of the teeth is controlled by me and a very skillful lab technician.  Everything I do is done in 3-D planning so that we can make the teeth as precise and naturally cosmetic as possible.  There are so many factors to consider… the video to find out!

Replacing Four Lower Back Teeth With Dental Implants and Bone Grafting – Start to Finish Detailed Video Review -Ramsey Amin DDS

This video has a lot of information on dental implants and bone grafting. There is also a lot of information on how the teeth and dental implant abutments are made in the rationale of why I did everything. You also see the sequence where three of the implants were placed in a delayed fashion and one was placed as an immediate dental implant.

***If you are considering having dental implants and perhaps socket bone grafting, this is a must-see video.**





Please be sure to watch the entire video as there is so much to learn about the entire process of having teeth replaced with dental implants. In this video I review the diagnosis, treatment planning, 3-D scan analysis, surgical placement of four implants and the restoration of the four implants with for non-connected monolithic zirconia crowns with prefabricated abutments.

This patient has several failing root canals and very heavily worked on teeth. The teeth have been crowned in re-crowned multiple times and now several molars need to be extracted. In fact a few of the crown/root canal teeth came apart during the healing!!! They were added to the list of teeth to extract and replace with dental implants.

I also show after photographs so that you can have a complete start to finish outlook on this procedure. I consider this patient a very basic case in my office. In the 3-D scan analysis, I discuss how the surgery and planning can prevent long-term complications such as peri-implantitis which is bone loss around implants.

I appreciate your comments and questions. I hope this video helps you.

Zirconia Dental Implants Pros and Cons Video

Are zirconia dental implants the answer?  The vast majority of dental implants are titanium alloys that have been in use since the mid 1960s.

The focus is whether the actual implant screw is made of zirconia or titanium.   Zirconia dental implants are attractive for those that may be concerned about a metal allergy.  In this blog post I describe the pros and cons of zirconia dental implants.  As of the year 2015, I would not recommend them… The scientific evidence and clinical practice does not support their claims.

The one piece design in itself is a very limiting factor.  The implant cannot be redirected by an abutment….  Right or wrong, position cannot be changed.

In my dental office in Burbank, California, I commonly use zirconia as the crown or bridge portion.  It is also very useful as an abutment which is the intermediary piece on a two-piece dental implant.  Both the crown/bridge and abutment portion are not embedded into the bone.  Zirconia bridges such as the Prettau dental implant bridge is extremely strong as long as it is made very thick.

In this post I also discussed what happens when orthopedic surgeons use zirconia as a hip replacement material.... You will be shocked to hear the results!!

Your comments and questions are welcome as usual.

Prettau Full Mouth Dental Implants ~3D planning by Ramsey Amin DDS

This is a case being planned for upper and lower Prettau dental implant Bridges. The patient just lost her lower front teeth extracted and now has no teeth at all. She can no longer wear a lower denture and desires dental implants that are nonremovable.

This video walks you through some of the clinical photographs involved in planning the case and then moves into 3-dimensional planning from a 3-D CBCT scan. I will show you how the implants should be spread out and placed into the best bone possible. The video also shows how a surgical guide is made from the 3-D scan planning that I personally do for every single case. I do not believe in outsourcing surgical planning to other dentists and technicians from companies that do not understand anatomy…. Yes this is very common!

The video highlights some of the powerful software that I use every day to plan surgeries for safety and predictability. The surgeries are performed in one of four surgical suite in my Burbank, California office

Thank you for watching!

Antibiotics for a Tooth Infection, Dental Implant, Bone Graft… Do I Need Them? 

In this short, but highly informative video, I review some of the common truths and misconceptions about antibiotics in relationship to tooth infections, dental implants and bone grafting.

Use of antibiotics should be judicious and carefully thought out.  Just because you have an “infection” in your tooth, it does not mean you need an antibiotic.  Also, not all “infections” are actually infections.  Not all infections can be cured by antibiotics alone.

Antibiotics are commonly needed for procedures that involved cutting through bone or addition of bone graft materials.  There is a limited supply of new blood vessels that can get your natural immune system’s protection in the first few days following a significant procedures such as a surgical extraction, a bone graft, sinus graft, apicoectomy and dental implants.

Antibiotics are extremely helpful in many situations.  I also discussed common questions such as antibiotic resistance and what happens with common stomach issues and what to do about them.

I think you will find this video helpful.  Please feel free to ask questions below.

All On Four Dental Implant Procedure Review: Is It The Best? –Ramsey Amin DDS

The All on 4 dental implant procedure has become quite popular. You probably even hear about it on radio and TV advertising. Even many dentists don’t really understand it. It is sometimes advertised as the “smile and a day” procedure.   All on four is simply a treatment option for replacing all of your teeth on the upper or the lower with just four dental implants. It is possible to replace all of your teeth in just 1 day. In fact I have been doing this for the last 15 years.

You just have to be very selective that you are the right patient for this type of procedure. I don’t suggest that the final teeth are made on the same day because you will not be able to test the teeth for how they look, feel or bite.  There are many steps to achieve a really good result and a full mouth reconstruction.

The All on 4 Dental Implant Procedure Video Review

There is a lot of hype about all on four. What is perceived is not always the reality. In this video I will review several things you should know about total teeth replacement with “ALL ON FOUR”.

Some advantages are:

Some disadvantages are:

  • Under engineered–only four implants are supporting what 14 upper natural teeth would do.
  • Cost is reduced by making a “fixed hybrid.” These are essentially fixed dentures which have high maintenance and break very often.
  • No implants are placed in the molar areas of your mouth where the bite force is the highest

Here is a patient a decade ago:


Generally speaking, 6 dental implants on the upper and 5 dental implants on the lower are minimum number for stable long-term bone.

This should be combined with an all zirconia or metal ceramic bridge rather than a hybrid, which are plastic denture teeth fused to a base metal. Depending on the size your jaw and bite force, you may need up to 8 dental implants on your upper jaw and 6-8 on your lower jaw.

Sometimes bone grafting cannot be avoided and is necessary to obtain good long-term results for you. You may require sinus bone graft if your sinuses are farther forward in your mouth.

I would strongly suggest all porcelain teeth, preferably CAD milled Prettau, if you have enough space from top to bottom. Porcelain teeth don’t stain, chip and break like plastic hybrid denture teeth do. I would also suggest that all on four or all on 6 or 8 are held in by screws rather than cement, if at all possible, based on dental implant angulation. This video should clarify a lot of questions you may have.

The all on four dental procedure is really heavily marketed and is rarely the best option but **can work for some**.

Remember your teeth are your body parts. I truly believe a customized solution for your particular situation is best. Some dentists just plan all on 4 dental implants for all patients regardless of their unique situations.

It is the equivalent of trying to make your mouth fit the prefabricated teeth, rather than making teeth to fit your mouth.

If my mom or dad were to ever need to replace all of their teeth, this is not the way I would do it.
