How are dental crowns made and are you interested in knowing that? Most likely, you’ve already been informed about crowns by your dentist or seen them in the advertisements, but what really does it take to end up with this additional tooth protection? It just so happens that designing or creating a dental crown is an interesting, detailed work that goes on away from the public eye and in dental laboratories. Let us examine this procedure closely.
What Exactly is a Dental Crown?
Before we explore the stage, we would like to discuss what actually is a dental crown first. A dental crown is referred to as an artificial restoration fitted on a person’s dental crown to enhance the head’s shape or function that may have been compromised due to infection or trauma. Crowns are indicated where a tooth structure has been lost to an extent that ordinary fillings will not suffice or if the patient has undergone a root canal procedure. There are many materials from which these can be manufactured like porcelain or ceramic or metal.
Most people wear crowns for dentition protection purposes, however most people may not know that crowns also enhance the beauty of ones smile. As they fill entirely in your mouth, they are manufactured individually with regard to size, shape, and color of the teeth. However, in order to achieve such a high degree of individuality, it is necessary to spend a lot of care at the stage of operating each crown.
Step 1: Taking a Mold of Your Tooth
This step in making the dental crown regarding the tooth starts at the dentists’ office. So, after your dentist has prepared your tooth (perhaps by cleaning or even altering it), they will probably be taking a mold or an impression of the tooth that requires the crown.
This impression is a very important part of the process because it makes sure that the crown will not be ill-fitting. During the impression taking, some wash-like material, which feels somewhat like putty, is used, and it is discomfort-free. Other offices have also adopted 3D imaging using digital scanners as opposed to traditional molds which are time-consuming but less accurate.
As soon as your dentist gets that mold, he or she dispatches it to the dental laboratory where the fun begins.
Step 2: Designing the Crown
As soon as the laboratory has the impression, a trained laboratory technician will start creating the crown designed for you. This is the stage where accuracy is of paramount importance. The crown should entirely cover the tooth, be well supported on the bite and, be coeval with the other visible teeth.
Most of the dental laboratories utilize sophisticated CAD applications to produce a model of your crown. The technology helps the technicians to make the crown much more accurately so that it feels comfortable inside the mouth.
The use of CAD represents significant progress since older methods that depended on the making of models were less efficient and some adjustments will later have to be made after fixing the crowns. And it also helps in improving the entire workflow, thus decreasing the delivery time of the crown.
Step 3: Choosing the Right Materials
As the design has now been successfully completed, it is high time to moult over on the material that your specific crown will be made of. Choice of the material will depend on some factors such as the position of the crown in the mouth and what the patient prefers.
The following are the commonly used materials in practice for use in crowns:
Porcelain or Ceramic: These materials come in handy when making crowns for anterior teeth since they are undetectable because of their appearance in resemblance to teeth. The BAD is that they do not offer flexibility as some of the other options out there.
Metal: These metal restorations are largely put on molars as they are tough being made from metals like gold of platinum. However, they do not have the best aesthetics.
Porcelain-Fused-to-Metal (PFM) Porcelain-fused-to-metal restorations are good for a number of patients as they combine the bests of both worlds. Porcelain and metal restorations.
CFD Dental Cares In which particular focal material has been identified and selected this brings the techniques to the very next phase.
Step 4: Crafting the Crown
This is where the fun begins! If the crown is made from porcelain or ceramic then the technician will create it according to the information provided in the design. The material is usually built up in layers creating a realistic appearance on the crown, on the other hand, the texture and color is also pay attention to.
Casting metal into the shape of your crown and how ever if metal is the halfway step in the process then these techniques are employed. In all these the aim is to make a restoration that not only aids in mastication and other functions but is also as close to a tooth as possible in appearance.
Manually, based on the user’s requests and specifications, crowns are shaped and adjusted. Making a dental crown, so to say is an interdisciplinary process. It is both art and science. In a sense the technician has to be an artist as well as a craftsman.
Step 5: Firing and Glazing
Once the shape of the crown has been achieved, it has to be made hard enough so as to be able to last through years of chewing and biting. This step is called firing. In case of Ceramic or Porcelain crowns the technician will put the crown into a porcelain furnace and fire the crown at higher than normal temperature.
This process strengthens the crown and makes it durable. The technician then after firing forms and applies what is called glaze over the crown and this gives the crown a slick and shinier appearance. Glaze also ensures the crown blends with the sheen of the rest of the teeth.
As at this moment, this crown has already attained a stage where it is almost completed. But at this stage, the crown is in need of further checks and adjustments.
Step 6: Quality Control and Adjustments
Quality control is one of the most vital steps in the process of making a crown. The dental technician carefully inspects the crown under the magnifier, observing its size, shape and any flaws if there are any. They’ll ensure it is the right size, shape, and colour; that, it meets the orders which the dentist made.
Some situations might warrant the need to modify the crown or perhaps just make small adjustments to the material already in place. This could imply changing the profile of the crown or adding another layer of porcelain to get the shade where it needs to be. Since each crown is individual, the technician makes effort to ensure quality thus returning them to the dentist for placement is in order.
Step 7: Sending the Crown Back to the Dentist
The crown is then returned to the patient’s dentist once all the checks have been done and the crown has passed all the necessary parts. The crown is handled carefully and shipped back to the office since it is a precious item. Or I would rather think such a delicate piece of work needs to be packaged properly.
At this stage your dentist will ask you to return for your visit where you would be fitted for the crown. The moment of truth is almost here, you are just about to fit your new crown.
Step 8: Fitting the Crown
On your next visit to the dentist’s office, the dentist will put the crown on your head and try it. They would try on the fitted crown and adjust the corresponding teeth to settle down their mouth. They would adjust it to their mouth, placing the crown on a tooth and asking the patient to gently bite it down and testing it to ensure that it feels right. If everything went well, the crown will be fixed onto the tooth.
but if it’s a crown that is going to be placed over a prepared tooth, it may require some trial fittings for accuracy. If this is the case, and it is common, it will only be for the period it takes to get a proper fitting crown.
Step 9: Cementing the Crown in Place
When this is perfect, one can then be ready to attach the crown to the abutment or the patient’s prepared tooth. They will make use of a certain bonding agent also known as crown cement to attach the crown to tooth. Since the hardening cement will dry quickly, when one is about to leave the office, the crown will already be fully placed.
After placing the requisite amount of cement to the abutment or the tooth and applying the crown, your dentist will recheck malo bite once more for only efficacy. After that, you can move around as you please, thanks to the new crown in your mouth, enabling you to safely chew and restore that tooth as well.
Step 10: Caring for Your Dental Crown
After stabilizing your prosthesis in our case a new crown, it follows that proper maintenance of the prosthesis must also be observed. The good side is, other than the routine dental practices that you perform, crowns do not require any extra maintenance. Just brush the teeth and strengthen the inter-dental brushes every now and then and make sure you also go to the dentist for check-up appointments.
Nevertheless, like every other structure crowning the tooth, these restorations can be very strong, relatively, but not indestructible. Avoid biting on hard objects such as ice cubes and pens, and for people who grind their teeth while sleeping, your teeth doctor might suggest a nightguard to keep your crown safe.
Indeed, in case you wear a dental crown properly, it can easily serve you for many years, on some occasions, even decades!
The Future of Dental Crowns: New Technologies
Dental technology is always advancing, and the way crowns are made is no exception. One of the most exciting developments is same-day crowns. With the help of advanced milling machines and 3D imaging technology, some dentists can create and place a crown in just one visit! No more waiting for your crown to be made in a lab.
Additionally, materials are constantly improving, making crowns stronger and more natural-looking than ever before. Who knows what innovations the future holds?
