Modern dentistry places a high premium on quality, and with good reason—patient care and treatment involve a lot of responsibility. Experiments are not permitted. Learn what you can do to ensure that your repairs last a long time.



Why do things crack or fracture?


A change in the hue of the restoration is the first indication of a crack or fracture. As time passes, the tooth structure may also turn stained. Dental technicians must be aware of what to look for in order to address issues as soon as they arise and limit further harm.


Dental technicians need to be aware that cracks can appear in any porcelain or composite restoration, but that because porcelain is tougher than composite, they tend to occur more frequently. It is also crucial to keep in mind that cracks do not always signal a problem with the restoration; they can be point to an issue with the tooth. For instance, if your patient requires root canal therapy or if there is oral sensitivity, the tension of biting and brushing will cause cracks to form in their porcelain restorations.


If your client-dentists inform you that one of their patients has returned to their office during the warranty period with a crack or fracture in one of their priceless restorations, the following questions will likely cross your mind:



  • Was there anything overly hard that the patient bit into?


  • Were the wall thicknesses so thin because there wasn't enough room?


  • Did I not choose the proper material?


  • Was there a bad batch that the manufacturer delivered?


  • Did the company introduce a substance that hadn't undergone enough testing?



Prevention vs. problem-solving


Such deliberations are entirely typical. Troubleshooting is one thing, though, and preventive is quite another. Who, after all, would want to find oneself having to confront those awkward questions? What steps can you take to reduce these risks?


The idea that dental technicians should just be concerned with troubleshooting is a frequent one. Dental technicians must be able to respond appropriately when a patient complains about a new crown or when there is a problem with a restoration that has already been installed. However, it's equally important to stay on top of preventative measures so that patients can enjoy their new smiles for years to come.


One thing you can and should do, despite the fact that there can never be 100% confidence, is to make sure that you and your dental technician are using tried-and-true materials. Making use of items that have been clinically tested can greatly increase your level of assurance. Many consumers feel overrun by the sheer number of offers at their disposal, especially in an era when more firms are offering novel materials, technologies, and services. They either start to experiment or they feel lost. While being receptive to innovations is crucial, it also carries hazards. Those that use tried-and-true materials and systems with a track record of dependability are making the right decisions. Dental materials that have been used before are more likely to provide long-lasting success and excellent reliability. We are all aware that excellence will win out in the end.


evidence-based system for all ceramic


The limits of traditional all-metal restorations are well known to many dental technicians. Although they can elegantly reconstruct teeth, they are prone to fracture and fading with time.


The good news is that an evidence-based all-ceramic system has emerged that can address these issues. This technique employs a special substance that is strong and able to withstand wear and discolouration. Additionally, it has a natural tint that won't deteriorate or alter with time.


This new material, which is stronger than conventional metal alloys, is also simpler to work with because it doesn't need particular handling or storage procedures. There is no comparison between the two materials in terms of durability and usability.


For many years, dental applications have used IPS e.max materials with success. The lithium disilicate glass-ceramic and zirconium oxide components of the evidence-based all-ceramic system are based on reliable scientific data. The clinical performance of a material can make all the difference when it has up to 15 years of clinical experience and about 120 million restorations put (based on sales numbers).


In general, it might be challenging to anticipate how long porcelain crowns will last. Treatment planning, diagnosis, material selection, including the use of dental alloys, aesthetic shade selection, occlusion, and dental technician or dentist technique are all factors that determine how long they last.
