Clinical ResearchSurgical extrusion with an atraumatic extraction system: A clinical study
Section snippets
Material and Methods
Study participants were recruited from a group of consecutive patients initially referred to a specialist oral surgery practice between January 2009 and July 2015 for possible extraction of their nonrestorable teeth. In 61 patients, 62 single rooted teeth were considered as potentially salvageable with surgical extrusion, despite subgingival fracture or caries. Ethical approval was obtained from the local ethics committee for the clinical and radiographic reevaluation after a follow-up period
Results
All 61 patients were invited for a follow-up examination. Eleven teeth could not be examined: 2 because of subsequent apical surgery, 2 because of extraction, and 2 because of patient death; 5 patients were unavailable. Thus, 51 participants with 51 treated teeth were recalled (82.3% recall). Of the 2 teeth extracted, 1 was extracted more than 5 years after extrusion because of a fractured coronal restoration. The other extracted tooth had been perforated during the extrusion attempt and was
Discussion
The present study showed a favorable outcome after surgical extrusion of nonrestorable teeth with a novel vertical extrusion system. In the patients treated, 82.3% of teeth deemed nonrestorable at referral could be reevaluated and were in function without any clinical or radiographic complications. In particular, none of the treated teeth showed infection-related or replacement resorption, whereas periodontal healing with transient resorption was detected in 9.8% of recalled teeth. Some
Conclusions
Based on the findings of this clinical study, the following conclusions were drawn:
- 1.
The AES may be successfully used for surgical extrusion to save nonrestorable teeth.
- 2.
These results encourage further prospective research into the long-term outcomes of this technique.

Furthermore, Krug et al21 observed root resorption processes on radiographic images in 5 of 51 teeth after surgical extrusion. After FOE, the present study did not detect resorptive processes in the apical region at all, which was consistent with the results of a prospective study on forced orthodontic extrusion.28

2020, Journal of the Mechanical Behavior of Biomedical MaterialsCitation Excerpt :Force-time plots show that as the loading increase paused, rapid stress relaxation occurred followed by a more gradual decay in measured force, which is consistent with animal-model (rabbit) data (Komatsu et al., 2007). Minimising extraction forces may be desirable to minimise the risk of root fracture and reduce the stress transferred to the dento-alveolar complex and may have biologically favourable results in terms of reduced trauma and improved healing, in particular in the case of surgical extrusion (Krug et al., 2018). Further investigations are required to identify whether or not slower extraction, i.e., longer periods of sustained input of force would result in a reduction in the maximum extraction force and whether this is clinically significant in terms of biological sequelae.
Intentional Replantation with an Atraumatic Extraction System in Teeth with Extensive Cervical Resorption
2019, Journal of EndodonticsCitation Excerpt :Extraction failures because of insufficient screw retention or alignment, root fracture, or unfavorable root morphology lead to complications in 11% of single-rooted teeth20. A clinical study revealed that the technical complication rate in teeth surgically extruded with an AES was 9.7%32. This case report shows a successful outcome of intentional replantation with atraumatic tooth extraction without complications such as root fracture or retention loss.
