The Trios 4 Procedure
Let’s face it, very few of us have perfect teeth, free of decay and fillings. You can probably see a filling or two in your own mouth, which do just that — “fill” a cavity, or hole, in your tooth left from the excavation of decayed tooth structure. In many cases, those fillings are made of metal material and can go bad, weaken the tooth, or get additional decay under or around it. In fact, 1.2 billion of these metal fillings will need to be replaced in the next 10 years. 3Shape Trios is a method used by thousands of dentists worldwide since 1987 not only to replace these fillings, but also to restore any tooth that is decayed, weakened, broken, etc. to its natural strength and beauty. Better yet, it’s done with all-ceramic materials that are tooth-colored in a single appointment!
Exam and Preparation for Trios 4
First, Dr. Amus examines the tooth and determines the appropriate treatment. It could be a simple filling, a full crown, or an Implant crown depending on how much healthy tooth structure is remaining and the clinical judgment of your Dr. Amus. Next, he administers an anesthetic and prepares your tooth for the restoration, removing decayed and weakened tooth tissue. This preparation is just like he would do for many other restorative techniques.
Then, your dentist takes an Optical Impression of the prepared tooth. Instead of filling a tray with impression “goop” that you must bite into and hold in your mouth until it hardens. A wireless camera is then used to take a digital picture of your tooth. This whole Optical Impression process takes only a minute or two.
Next, the 3Shape Trios 4 machine helps Dr. Amus create the restoration for your tooth. The 3Shape Trios 4 software takes the digital picture and converts it into a 3-dimensional virtual model on the computer screen. He then uses his dental expertise to design the restoration using the 3Shape computer program. Within a few minutes, Dr. Amus clicks a button, and the restoration design data is sent to a separate milling machine in the office. A ceramic block that matches your tooth shade is placed in the milling machine. About 10 – 20 minutes later, your all-ceramic, tooth-colored restoration is finished and ready to bond in place. Finally, your dentist tries the restoration in your mouth to ensure proper fit and bite. The restoration is then polished and bonded to the prepared tooth. Your tooth is restored with no “temporary” or return trip necessary. All of this is done in a single appointment! Ask us about 3Shape Trios 4 today.
What is 3Shape? 3Shape is an acronym…
- Chairside: The technology is in the dental operatory and used while you are in the chair
- Economical: The procedure is economical for both dentist and patient
- Restorations: The procedure restores your tooth to its natural beauty, function, and strength
- Esthetic: The restorations are metal-free and tooth-colored
- Ceramic: High-strength ceramics are used that are close in composition to your natural tooth structure.
3Shape Trios 4 is an advanced dental restorative system that allows your dentist to restore decayed teeth, place crowns, remove defective amalgam fillings, or place cosmetic veneers in just one appointment. This allows you to have the highest quality, most lifelike dental restorations in just one visit to the dentist…in, out, and on with your busy life.
3Shape Trios 4 Acquisition Unit
The Trios 4 Acquisition Unit is wireless and houses a medical grade computer and camera. Your dentist uses the camera to take a digital picture of your prepared tooth. This picture is used instead of a traditional impression. This means no impression tray and material for you to gag on. The computer and 3Shape software converts the digital picture to a three-dimensional virtual model of your prepped tooth. Your dentist then designs your restoration right on screen using the software while you wait (and watch!). This software can assist your dentist with designing any single tooth restoration: crowns, inlays (fillings), onlays (partial crowns), teeth veneers and Implant crowns as well. Once your dentist has designed your restoration (usually about 5 minutes), he clicks a button, and the design data is communicated via a wireless radio signal to the Milling Unit.
The Milling Unit
Your dentist or dental assistant selects a ceramic block that matches the shade of the tooth being repaired. He or she then inserts the block into the Milling Unit. The data from the Acquisition Unit is used to direct two diamond-coated burs to carve the block into the indicated shape of the restoration. This process usually takes 8 to 18 minutes depending on the size and type of restoration. After the milling is finished, your dentist polishes the finished filling or crown and bonds it into place.
