Abstract

Abstract:

Objective

To evaluate the clinical effect of minimally invasive extraction of difficult maxillary impacted third molars.

Methods

Seventy-eight maxillary impacted third molars were involved in this study from January 2012 to March 2017 from the Department of Oral and Maxillofacial Surgery, Stomatology Hospital of Haizhu district. Cone beam CT was executed to find out the location between impacted third molars and adjacent anatomical structures. Excluding extraction contraindications, impacted third molars were extracted using minimally invasive apparatus. Evaluation of effect and complication incidences were made in 1 week after operation.

Results

Operation time lasted from 3 minutes to 45 minutes, with an average of 13 minutes. Patients maintained good comfort and less postoperative discomfort in minimally invasive extraction. None had serious complications.

Conclusion

It was practicable and preponderant to adopt minimally invasive extraction for difficult maxillary impacted third molars.
