ABSTRACT
@#With the rapid development of implant technology, implant restoration is a conventional treatment option for adult patients with tooth loss. Severe dental lesions, trauma, tumors, abnormal development and other reasons can cause dental defects and even dentition loss in children and adolescents. There has been hesitation to perform implant therapy for growing children because of the growth period; thus, little is known about the outcomes of the osseointegration procedure in young patients. Therefore, this article reviews the current literature to discuss the use of dental implants in children and adolescents. According to current studies, orthodontic treatment or transitional restoration should be undertaken based on the characteristics of the children and adolescents. Implant surgery should be performed after the end of the peak growth period. For patients with severe dentition defects, relevant criteria should be established before implant surgery to evaluate the effect of implant therapy in children and adolescents. The patients should be treated with a multidisciplinary, staged and long-term treatment approach. Most of the recent literature consists of case reports and short-term studies. There is an urgent need for more studies in this field with long-term follow-up.
ABSTRACT
Objective@# This study aims to investigate the clinical effect of the improved extraction of low horizontally impacted mandibular third molars via a “three-section” method.@*Method@#Sixty patients with low horizontally impacted mandibular third molars on both sides were selected for this study. A high-frequency electrotome, a 45 degree high-speed turbine and a special long drill needle were used in the test group. The improvement was called “three section”, which meant that the tooth was cut into three parts; first, the middle part was taken, then the root, and then the crown. One month later, the other side (control) was extracted using the regular method (the tooth was cut in two parts, and the crown was removed first). Operation time, swelling, pain, and limitations to mouth opening were carefully recorded and statistically analyzed.@*Results@#The time for the modified “three-section” method, which was used to remove the third molar embedded in the lower part of the lower jaw, was (10.05 ± 0.51) min, while the mean time for conventional extraction was (20.15 ± 0.88) min, and the difference was statistically significant (P< 0.01). There were significant differences (P< 0.01) in swelling, pain and limitations to mouth opening between the test group and the control group.@*Conclusion@#he use of the “three-section” method to extract third molars horizontally embedded in the lower jaw is associated with a shorter operation time, reduced trauma and reduced postoperative reactions, and it has valuable clinical applications.
