Minimally invasive surgery versus traditional chisel crown method in extraction of impacted mandibular third molar

Abstract

Objective To analyze and evaluate the effects of minimally invasive method and versus traditional chisel crown method in the extraction of impacted mandibular third molar. Methods 102 patients with impacted mandibular third molar treated at our clinic from April, 2015 to April, 2016 were selected as study objects and were divided into a study group and a routine group using random number table method, 51 cases for each group. The routine group took traditional chisel crown extraction and the study group received minimally invasive treatment. The postoperative extraction time and complications of the two groups were compared and analyzed. The patients’ quality of life were evaluated by PoSSe. Results The average extraction time was (20.4±3.2) min in the study group and (33.7±4.1) min in the routine group, with a statistical difference (P<0.05). The incidence of intra-operative complications and the score of PoSSe were lower in the study group than in the routine group, with statistical differences (P< 0.05). Conclusions Minimally invasive surgery in the extraction of impacted mandibular third molar is more effective and needs shorter operation time than traditional chisel crown method.
