In-House Lab

In-House Laboratory

All of our Dental Implant Prosthetics, Dental Crowns, Dental Implant Crowns, and Dentures are made right here in our Little Rock office to ensure that every step of the process is technically correct. Our Dental Lab Technicians, Grant, Chance, and Beth, and our doctors work closely to make sure every detail is perfect – just for you.


At Hart & Coco, our lab technician and doctors can recommend a smile that looks good on you. Take comfort in knowing that all of our dental prosthetics are made right here in our office, and you have the final say in all of the details.

We begin the design and setup of a smile using your input, facial measurements and facial profile to choose teeth that are proportionate with your stature and that meet the requirement of symmetry that is the basis of a beautiful smile.

We have the ability to make prosthetic teeth that are as unique and as natural as you desire.


We only use the best materials. In our acrylic prosthetics, we use the highest quality, most anatomically accurate acrylic teeth available on the market today.

Ivoclar was founded in 1923 and is located in Liechtenstein – a small country located in the Swiss Alps between Switzerland and Austria. They use a proprietary composite layering process in the fabrication of their acrylic teeth that makes them not only supremely aesthetic, but extremely durable.

We did our research and began using Ivoclar products in 2005 – and we haven’t looked back since. Ivoclar’s acrylic teeth deliver our need for a prosthetic tooth that is worthy of our patient’s and our laboratory’s high demands.

Assistant making dental implants


Perhaps the most important component of our laboratory is our technician-doctor collaboration. That is where all of the elements of excellent prosthetic dentistry coincide.

Our laboratory exercises the same care and detail of technique on each case, respecting the requirements and rules of our materials, to ensure a precise, long-lasting and beautiful end result.

Crowns & Bridges

At Hart & Coco, we believe that crowns should look, feel and function like natural teeth. We use a proprietary milling process to fabricate all of our crowns and practice careful techniques of delivery to ensure that when they are delivered and adjusted to fit and that they maintain their anatomy – not get ground off.

We can match any available shade of tooth you desire. By choosing a blending shade similar to a patient’s natural teeth, we can allow the prosthetic teeth to disappear once they are placed in the patient’s mouth.


The materials used to build a crown are paramount to its longevity. At Hart & Coco, we use zirconium – an incredibly durable, hard, yet naturally-white and beautiful material – to fabricate all of your crowns.

All of your zirconium crowns are fabricated in our own laboratory, on-site, under our direct supervision.

The Hart & Coco Laboratory fabricates these zirconium crowns using a ZirkonZahn Computer-Aided-Design and Milling Process (CAD-CAM).

Each crown and bridge is custom designed digitally. That design is then sent to a milling machine where each crown is milled from a solid block of zirconium.

This computer design and milling process yields stunning anatomy and incredible strength in each crown, bridge or other dental prosthesis it creates.

Zirconium: The Kryptonite of Dental Materials

There are several different forms of the element Zirconium. There is the Zirconium dioxide that we use in dentistry to make crowns, dental implants and dental implant parts, but there is also the cubic form of zirconium – cubic zirconia found in diamond simulants or ‘fake’ diamonds.

Zirconium is a very stable, very bio-compatible material that will ensure a beautiful and long lasting smile…

What Patients Ask Regularly About

What is a dental implant?

A dental implant is a synthetic tooth root that is threaded and metallic (like a wood screw) and is commonly made of titanium. The inside of the implant is threaded (like the outside) and allows a dentist to screw all different types of parts and pieces into it. A dental implant can be used to replace a single tooth (by attaching a crown to it) or can be used to replace a jaw full of missing teeth (using 4-6 implants).

Can I get an MRI or go through airport security with a dental implant?

Yes! Titanium is a non-magnetic metal and it will not give you any trouble when getting an MRI or when being checked through airport security.

How do All-on-4 Dental Implants compare to traditional implants?

The All-on-4 dental implant technique utilizes only four implants per arch, whereas traditional implants utilize anywhere from six to eight implants, or more, in each arch. The implants of the All-on-4 procedure are also placed at an angle, which allows for increased contact by using the natural support of your bone. In addition, the All-on-4 procedure requires no bone grafting for most patients, which is common in traditional implant procedures. Therefore, All-on-4 dental implants save time, money, and discomfort.

What is the All-on-Four Dental Implant procedure?

This is a treatment option for persons who are missing all of their teeth in a jaw, or have a jaw full of non-restorable teeth. This option will replace all missing teeth in a jaw using only four well-spaced and well-placed dental implants. Typically, a patient will have teeth “fixed” to (screwed into) the implants in that jaw on the day that they are placed.

This temporary set of “fixed” teeth will remain in place for four months while the bone heals nicely to the implants. After 3-4 months, this temporary set of teeth will be removed and replaced by the dentists with the final set of teeth. The final set of teeth will contain a framework (or skeleton) that supports the prosthetic teeth – this makes them stronger and more durable, and allows the patient to eat a wider range of food types without the chance for fracture. This option is NOT removable by the patient and is to be cleaned daily while in place as if brushing their natural teeth.

These prosthetics have a varied life-span ranging from 10 years to forever, depending on the materials used to make them. The vast majority of All-on-Fours are composed of acrylic teeth, acrylic pink gum tissue and zirconium supporting framework. These acrylic-zirconium prosthetics have an expected life span of 10 years (based on the wear rating of the company that makes the acrylic teeth), but can last less than or much greater than 10 years depending on how the patient uses and cares for the prosthesis once delivered. Someone who grinds their teeth or uses their prosthesis to open bottles will experience a shorter life span with their teeth than someone who uses their teeth for more normal functions (eating, smiling, etc.).

A patient has the option of having their All-on-Four made fully of zirconium. In this case, the prosthesis will look and feel much more natural, rigid and substantial in terms of chewing ability and thickness of the restoration. A fully zirconium restoration will feel much less bulky and will have much sharper teeth (more natural) as compared to the acrylic-based version mentioned above. The process of making the zirconium All-on-Four prosthesis is much more labor-intensive, more technique-sensitive and requires costlier materials than the process to make the acrylic version, and thus is more expensive. Because of its strength, Hart and Coco provides a 10 year guarantee to the zirconium version of the All-on-Four (but we expect it to last much, much, much longer). No warranty or guarantee is provided for the acrylic-based All-on-Four.

How are All-on-4 Dental Implants different from dentures?

All-on-4 implants are a set of teeth that look and feel like natural teeth. All-on-4 dental implants:

Are “permanent” teeth that are brushed and cleaned like natural teeth, Do not have plastic across the roof of your mouth, Do not have to be taken out, Do not need adhesives, Are comfortable because they do not press down on your gums, Allow you to experience the hot and cold of your food, as well as the taste, Allow you to bite with increased force (up to 70% more), so you can eat all of your favorite foods again, Prevent bone deterioration, Restore your facial features
