“…Postoperative reactions, including swelling, pain, and trismus, were used to evaluate the degree of surgical trauma. [ 20 , 21 , 34 , 35 ] Some authors reported that measurements of postoperative reaction reflected the degree of surgical trauma after alveolar surgery [ 24 , 27 , 34 ] , which was similar to the present study. This study showed that the MMO was slightly lower in the traditional surgery group than in the improved surgery group at 2, 3, and 4 days post-surgery, and we deduced that the long surgery time of traditional surgery might result in jaw elevator muscle spasm and extended period of soft tissue retraction, which was in line with the study described by Menziletoglu et al [ 29 ] However, there were no significant differences in pain, swelling, and trismus between the improved and traditional surgery groups, which verified that the improved surgery did not increase surgical trauma.…”

The aim of the present study was to observe the abrasion of implant drills and postoperative reactions for the preparation of the interradicular immediate implant bed during the COVID-19 pandemic and beyond. Thirty-two implant drills were included in four groups: blank, improved surgery, traditional surgery, and control. In the improved surgery group, a dental handpiece with a surgical bur was used to decoronate the first molar and create a hole in the middle of the retained root complex, followed by the pilot drilling protocol through the hole. The remaining root complex was separated using a surgical bur and then extracted. Subsequently, the implant bed was prepared. Implant drills were used in the traditional surgery group to complete the decoronation, hole creation, and implant-drilling processes. The tooth remained intact until the implant bed was prepared. The surface roughness of the pilot drill was observed and measured. Surgery time, postoperative reactions (swelling, pain, and trismus), and fear of coronavirus disease 2019 scale (FCV-19S) were measured and recorded, respectively. Statistical analysis revealed significant difference with surface roughness among blank group (0.41 ± 0.05 μm), improved surgery group (0.37 ± 0.06 μm), traditional surgery group (0.16 ± 0.06 μm), and control group (0.26 ± 0.04 μm) ( P < .001). Significant differences were revealed with surgery time between improved surgery group (5.63 ± 1.77 min) and traditional surgery group (33.63 ± 2.13 min) ( P < .001). Swelling, pain, and trismus (improved group: r ≥ 0.864, P ≤ .006; traditional group: r ≥ 0.741, P ≤ .035) were positively correlated with the FCV-19S. This study proved that a new pilot drill could only be used once in traditional surgery but could be used regularly in improved surgery. Improved surgery was more effective, efficient, and economical than the traditional surgery. The higher FCV-19S, the more severe swelling, pain, and trismus.

“…The average operating time of all the extractions was adequate compared with the previous studies 18 , 19 , 26 , 27 . The post-operative reactions 28 (pain, limited mouth-opening, swelling) are mild and acceptable compared with other studies of mandibular third molar extractions 10 , 18 – 20 . In the three cases of temporary IAN injury, all of the teeth located deeply and contacted or penetrated to the canals, which may be the cause of nerve injury 29 .…”

“…Considering the remarkable characteristics of less trauma and fewer complications, the novel method of mesiolingual root rotation is supposed to be introduced in extraction of horizontal mandibular 3rd molars. However, though there are some studies mentioned lingual split technique 6 – 10 , none of them has described the details of lingual root rotation according to our knowledge. Several problems as follows are to be answered: ①Is there a comprehensive evaluation for the deep impacted mandibular 3rd molar?…”

Extracting horizontal mandibular 3rd molars face considerable difficulty due to the large bone and adjacent tooth resistances. This study aims at evaluating the effectiveness of a novel method-mesiolingual root rotation to extract wisdom teeth of this type. In this study, 73 horizontal teeth extracted using piezosurgery were reviewed and classified based on impaction depth: position I, II, III refers to the highest portion of the crown on a level with upper 1/3, middle 1/3, lower 1/3 of the 2rd molar’s root. Based on the surgical simulations on their 3D CBCT reconstructions, traditional method(crown distal rotation) and novel method(root mesiolingual rotation) are applied. 79.17% of teeth in position I and 57.89% of teeth in position II were designed using traditional method, 83.33% teeth in position III were designed using the novel method(p < 0.05). The surgeries were performed according to the designs. Two cases in position II using traditional method were found temporary inferior alveolar nerve(IAN) injury; while only one case in position III using novel method got temporary IAN and lingual nerve injury. Our study suggested that root mesiolingual rotation is an effective method to extract the horizontal mandibular 3rd molars, especially the deep impacted ones.

Purpose The aim of this study was to evaluate the performance and to assess the postoperative sequel and quality of life after removal of impacted mandibular third molars using piezoelectric surgery compared with conventional rotatory osteotomy. Patients and methods A single blinded, randomized, control clinical study was performed. Sixty-three patients (44 males, 19 females) who presented with bilaterally asymptomatic impacted mandibular third molars were included in this analysis. Each patient was treated, at two separate sessions approximately 4 weeks apart, with a conventional rotatory hand piece on one side of the mandible and a piezoelectric device on the contralateral side. Patients were followed up on postoperative days 1, 3, 5, 7, and 15 to rate the pain, swelling and trismus. Inferior alveolar nerve paresthesia was evaluated up to 12 months postoperatively. Results The severity of the pain, trismus and swelling using the piezosurgery were significantly different from the rotary group. In both groups, pain was most intense and peaked during the first post-operative day, while swelling and trismus reached peak levels on the third postoperative day. The piezoelectric procedure resulted in a significantly longer procedural duration compared to the rotatory surgery ( P < 0.001). Conclusion Piezoelectric surgery is considered a viable alternative technique compared to the conventional rotary systems and can improve a patient’s quality of life. Thus, piezoelectric surgery might be a preferred modality for patients undergoing complicated surgical extraction of impacted lower third molars.
