Treatment Modalities of Uncomplicated Crown Fracture in Anterior Maxillary Permanent Teeth: A Systematic Review.

Aim: Several treatment modalities have been used to restore crown fractures in case of uncomplicated crown fractures. Although many treatment modalities have been reported, there is no consensus on which one has the best results in terms of success and durability. This systematic review of treatment modalities in uncomplicated crown fractures aims to provide the most common and successful treatment modality for each patient's unique needs, balancing conservation, aesthetics, and long-term durability.

Materials and methods: Three electronic databases (PubMed, Scopus, and Google Scholar) were searched for articles regarding treatment modalities in uncomplicated crown fractures in anterior maxillary teeth.

Results: Following the application of the inclusion and exclusion criteria, 10 case reports, four case series, and two retrospective studies were selected for the review. These studies reported on fragment reattachment, direct composite resin, and veneers for the management of uncomplicated crown fractures. Fragment reattachment was the most preferred treatment modality, with milk, water, or sterile saline used as storage mediums. Direct composite restoration was preferred for missing or bad-shaped fragments or longevity. Veneers were given for aesthetic consideration and fracture resistance when the crown structure was majorly affected by the fracture. Fragment reattachment was favored in 63% of the articles included in the review followed by direct composite restoration in 26% of the articles. Venners were used in about 11% of the articles. Composites depicted a higher survival rate and a better outcome than fragment reattachment. Follow-up periods ranged from 1 week to 4 years, and all articles successfully re-established function and aesthetics, except for one tooth that required root canal treatment.

Conclusion: Fragment reattachment, direct composite restoration, and veneers are successful treatment modalities in uncomplicated crown fractures of anterior teeth. The choice of treatment depends on various factors like availability of fragments, age, and financial condition of the patient.
