Conclusion :
In total, 1821 restorations were evaluated and the failure rate was
24.1% (439 restorations), without taking into consideration the
follow up times
In two studies with up to five years of follow up, no restoration
failure was reported , while in one study on traumatized teeth all 70
Class IV restorations placed prospectively failed up to seven years
after placement so will depend on the technique and dentist care.
The overall results of the study showed that anterior restorations had a
good clinical performance, with low failure rates and moderate to high success rates in the long term .
Fracture of tooth or restoration was the most common main reason for
failure among all studies, accounting for 25% to 100% of all failures in
those studies that reported fractures.
Loss of restoration or anatomical form were the main reasons for failure in
two studies each, respectively accounting for up to 68% and 60% of all
failures in those studies
In general, reasons for failure related to aesthetic qualities of the
restorations, such as colour match, anatomical form, and surface stain
were more frequent reasons for failure in studies where restorations were
placed for aesthetic reason. Relatively Limited numbers of restorations failing due to endodontic complications or secondary caries
In anterior teeth, Class IV restorations involving the
incisal edge are subjected to high masticatory loads, with fracture as possible clinical outcome over time.
IN CONCLUSION - composites are good short to medium term solution for restoring the front teeth , with higher failure rates in people who are grinders, there is no damage to the teeth usually if the teeth are not cut down to improve shape too much , and composites bond best to enamel than if dentin is exposed.
