Increased wear resistance
The build-ups have wear resistance very close to the wear resistance of natural tooth enamel, which is extremely important in the treatment of chewing teeth. The fact is that if you restore the chewing surface of the tooth using a composite material, then over time the tubercles from the composite can wear out, and the tooth will no longer be effectively involved in the chewing process. Another thing is if the tooth is restored using a composite or ceramic insert, which have a wear indicator equal to the enamel. This ensures that the bite does not deform due to increased wear of the chewing teeth.
Build-ups have a much higher strength than composites used to restore teeth directly in the oral cavity. Needless to say, the stronger the material from which the dental restoration is made, the longer it will last faithfully?
Reduce of the repeated caries risk
In the manufacture of restoration in the oral cavity, the composite from which it is made, undergoes the process of shrinkage during polymerization. This leads to the appearance of a microscopic edge gap. The larger the volume of restoration, the larger the marginal gap, which over time can lead to a relapse of caries due to the fact that favorable conditions are created for the accumulation of plaque in the gap. The build-ups made by the dental technician go through the stage of shrinkage in the laboratory and are fixed in the oral cavity by a liquid composite, the layer of which is negligible and the shrinkage of this layer can be really neglected. Accordingly, the risk of caries recurrence is also negligible.
Careful study of the shape of the tooth
When restoring a tooth in the oral cavity, the doctor has a shortage of time and space, given the fact that it is difficult for the patient to keep his/her mouth open for a long time. The dental technician is deprived of such problems in the laboratory and, accordingly, can devote much more time to the manufacture of the build-up.
Careful study of tooth quality
When restoring a tooth in the oral cavity, the doctor is not able to polish some surfaces of the dental restoration. In the laboratory, the technician has free access to all surfaces and cannot only polish them, but also cover them with a special layer – glaze, which creates a perfectly smooth surface on all surfaces. Plaque is much worse on a well-polished surface.
Saving patient time
The manufacture of dental build-ups suggests that the bulk of the work is done in the laboratory and the patient does not need to spend much time in the clinic, which undoubtedly speeds up the treatment time and saves the patient time. The patient does not sit in a chair while a friendly team of a doctor and assistant prepares a filling in his/her mouth. The doctor, having processed the cavity, takes the casts and, putting temporary fillings, says goodbye to the patient until the next appointment, during which he/she solemnly cements the build-ups. Thus, in two visits, you can cure much more teeth than in the case of a filling. However, it's all pretty expensive. Although high cost is a relative concept. If the patient earns much more money for the time saved, then maybe it makes sense to think about it. The time spent on direct restoration of the tooth in the oral cavity is approximately two hours. Agree that with the restoration of several teeth, the gain in time can be significant.
Perfect tooth color and transparency
In the manufacture of tooth build-ups, the technician has the ability to perfectly color the build-up, simulating the natural color of the tooth and the transparency zone. This gives the restored teeth a perfect look.
