Abstract
Aim: To evaluate and compare skeletal, dental, and soft tissue parameters by therapeutic extraction of first premolar and nonextraction distalization of maxillary and mandibular arches in bimaxillary proclination using the skeletal anchorage system.
Materials and methods: About 40 orthodontic patients undergoing extraction or nonextraction treatment are enrolled in a randomized clinical trial. Participants are randomly assigned to either the extraction or nonextraction group and receive treatment augmented with skeletal anchorage. Mini implants were placed in the extraction group for retraction and infra-zygomatic crest (IZC) and buccal shelf screws were placed in the nonextraction group for distalization.
Observations and results: Comparison between the ages of the patients among both Groups showed no significant difference. A significant difference is observed in dental and soft tissue parameters before and after the treatment in group A, whereas skeletal parameters also showed significant changes along with dental and soft tissue parameters in group B.
Conclusion: There is a significant change in the position of incisors by retraction and facial profile improves gradually in group A while for group B, a marked change in lower facial height was even seen. On comparing both the groups, a highly significant difference can be seen with respect to the amount of incisor retraction and change in molar inclination. The time taken for retraction of incisors is less in comparison to distalization.
Clinical significance: With this, we can easily avoid premolar extraction, and in cases of impacted third molars distalization as when indicated can be helpful as a part of the nonextraction treatment plan.
期刊介绍:
The Journal of Contemporary Dental Practice (JCDP), is a peer-reviewed, open access MEDLINE indexed journal. The journal’s full text is available online at http://www.thejcdp.com. The journal allows free access (open access) to its contents. Articles with clinical relevance will be given preference for publication. The Journal publishes original research papers, review articles, rare and novel case reports, and clinical techniques. Manuscripts are invited from all specialties of dentistry i.e., conservative dentistry and endodontics, dentofacial orthopedics and orthodontics, oral medicine and radiology, oral pathology, oral surgery, orodental diseases, pediatric dentistry, implantology, periodontics, clinical aspects of public health dentistry, and prosthodontics.
