Abstract

Purpose: To compare the clinical efficiency of two types of T-shaped coronectomy applied in extraction of impacted mandibular third molars. METHODS：One hundred and twenty patients meeting with the criteria were randomly divided into 2 groups. Two types of T-shaped coronectomy were applied in extraction of impacted mandibular third molars. Indexes including operation time, intraoperative anxiety, postoperative pain and limitation of mouth opening were recorded and analyzed with SPSS 22.0 software package., Results: Patients with transverse method experienced more time in operation [(17.41±3.72) vs (15.22±2.53) min], with less intraoperative anxiety (P<0.05). There was no significant difference in postoperative pain and limitation of mouth opening(P>0.05) between two methods., Conclusions: Transverse T-shaped method can alleviate intraoperative anxiety, while longitudinal method is more conducive to shortening operation time.

Abstract

Double-root mandibular third molars are the common types of mandibular third molars that are prone to impac-tion. Based on the summary of clinical cases and experience, the commonly used crown-root separation technique is improved as diagonal root separation technique that divides the roots by the line connecting the distal axis angle to the root furcation. This new method improves the efficiency of the operation and reduces surgical trauma. This paper details the surgical method, minimally invasive mechanics, and key points of this technique, compares the technique with the crown-root separation tech-nique, and discusses their joint applications.
