Lecture Description

Rapid Maxillary Expansion (RME) is a cornerstone of orthodontic treatment, established for decades as a useful adjunct. Since the introduction of CBCT, many reports have shown that tooth-borne RME has the undesired effects, such as loss of buccal bone after the expansion, and significant buccal flaring of the dentition. Bone-borne RPE has been reported, with mixed results; the amount of skeletal expansion and the tipping effects are controversial between bone-borne and tooth-borne RME. Among these, Micro-Implant Assisted Maxillary Skeletal Expander (MSE), known as a tooth bone borne type hybrid expander, has several advantages. Guide holes in the expander provide beginners the solution on where to place the miniscrews. It is commercialized and easy to obtain ready-made products. And also, the treatment results are fairly consistent. These merits allowed the popularity of the appliance all over the world. Many clinicians favor the MSE because it can overcome the disadvantages; so therefore, there are explosion of clinical studies on this appliance. But, could this hybrid expander empower "Targeted transverse correction in accordance with different type of maxillary deficiency?"

A new treatment system called ‘Biocreative Orthodontic Strategy, BOS’ developed by Dr Kyu-Rhim Chung to implement independent target teeth/bone/soft tissue movement while avoiding extending unnecessary orthodontic appliances to non-target segments during the orthodontic treatment period. Since January 2004, the speaker has been continuing to apply different types of bone borne expander to clinical practice: Modified Haas Type bone borne expander or Tissue bone borne expander, Biocreative C-Expander (C-Expander). The Haas type expander is bonded with composite to four to six mini-implants. There is no contact with dentition. The device produces very effective skeletal expansion with minor tipping of the maxillary processes, and without additional buccal flaring of the posterior teeth. This essentially eliminates the undesired side effects of tooth-borne RME or hybrid type expander. An additional benefit is that after expansion, the skeletally supported expander can be connected to individual teeth to act as an anchor unit for target tooth movement. This treatment protocol fits the BOS precisely. Through this presentation, the speaker wants to compare treatment effects and periodontal changes among conventional hyrax expander, MSE, and palatal side C-expander with scientific evidences and related clinical case reports.
