Surgical extrusion was introduced as a crown-lengthening technique for treating Crown root fractures. This simple and easy-to-perform procedure is a viable treatment option for managing highly damaged anterior teeth.
Huang et al., in their recent study published in The Journal of Prosthetic Dentistry, concluded that Surgical extrusion may be used for saving otherwise nonrestorable teeth. This procedure has promising rates of survival when teeth selection is proper and the procedure is well executed.

The surgical extrusion technique has been advocated for severely damaged teeth as well as for intruded and unerupted teeth. To address the lack of a quantitative literature analysis, this study aimed to provide a comprehensive overview of surgical extrusion, assess its applications and outcomes, and identify topics for future research.
Researchers conducted an electronic search in leading databases in April 2023. They included studies with surgical tooth extrusion or synonyms present in titles or abstracts.
Bibliographic analysis, co-occurrence analysis, and coupling of publications were performed. The analysis of variance assessed the characteristics of the subgroups based on indications. The Kaplan-Meier method in the R software program evaluated survival rates.
Key findings from the study are:
A total of Fifty-one studies (1982 to 2023) were included.
The Journal of Dental Traumatology and the Journal of Prosthetic Dentistry combined published one-third of the papers and acquired the most citations.
The burst detection of keywords revealed four popular research topics: the Benex extraction system, chlorhexidine for infection control, rigid or semi-rigid splints to decrease the risk of complications, and novel restorative materials to improve esthetics.
The survival rate was 96.36% among 316 participants with 330 extruded teeth.
There were no significant differences found in study types, geographic distribution, publication year, or citation counts among the four subgroups. These are surgical extrusion for subgingival fractures, extensive caries, intruded teeth, and unerupted teeth.
A significant difference was observed among the four subgroups' Kaplan-Meier curves.
Concluding further, they said, in this study, surgical extrusion was demonstrated to save otherwise nonrestorable teeth, with promising survival rates when teeth selection is appropriately made and the procedure is executed correctly. It's mainly used for subgingival fractures, extensive caries, and intruded and unerupted teeth. It's a reliable option for restoring severely damaged teeth, especially maxillary anterior teeth.
