What are the effects of orthodontic treatment for distalising upper first molars in children and adolescents?

This summary is based on the review published in the Chochrane database of systematic reviews: Orthodontic treatment for distalising upper first molars in children and adolescents (October 2013) Safa Jambi, Badri Thiruvenkatachari, Kevin D O’Brien, Tanya Walsh   Context When orthodontic treatment is provided with fixed appliances, it is sometimes necessary to move the upper molar teeth backwards (distalise) to create space or help to overcome anchorage requirements.

How effective is preemptive analgesia on postoperative pain following third molar surgery? Review of literatures

This summary is based on the article published in the Japanese Dental Science Review: Effectiveness of preemptive analgesia on postoperative pain following third molar surgery? Review of literatures (November 2013) Akira Yamaguchi and Kimito Sano  Context  Surgery to remove the mandibular third molar is relatively invasive and is often associated with postoperative pain, swelling and trismus, which are frustrating for both patients and surgeons.

How successful are implants for orthodontic anchorage and what are the reasons of their failures?

This summary is based on the article published in Implant Dentistry: Implants for Orthodontic Anchorage: Success Rates and Reasons of Failures (April 2014) Juan C. Rodriguez, DDS, Fernando Suarez, DDS, Hsun-Liang Chan, DDS, MS, Miguel Padial-Molina, DDS, PhD, and Hom-Lay Wang, DDS, MSD, PhD Context In orthodontics, controlled forces are applied in specific directions to move teeth from improper locations into what is considered an “ideal” physiologic/esthetic location. To provide the movement, a steady and strong support known as orthodontic anchor is required. Anchorage, by definition, is a resistance to displacement provided by a static object. The most common anchor used is the patient’s own dentition; however, in some cases, the anchorage is limited or ...
