BACKGROUND:Recent studies have shown that osteoclast differentiation factor is closely related to osteoclast differentiation, formation and function in bone remodeling during orthodontic tooth movement. OBJECTIVE:To observe the effects of three kinds of orthodontic appliances on the expression of osteoclast differentiation factor at the pressure side of rat periodontal tissue during remodeling process and to explore the biocompatibility of the orthodontic appliances with the host tissues during orthodontic treatment. METHODS:Eighty healthy Wistar rats were selected to establish animal models of orthodontic tooth movement, and then randomly divided into four groups: control group, MBT group, Begg group, Damon Ⅲ appliance group. Four animal from each group were sacrificed at 3, 7, 14 days after wearing orthodontic appliances. The tartrate-resistant acid phosphatase staining was used to count the osteoclasts at the pressure side of alveolar bone tissue; real-time quantitative PCR detection to detect mRNA expression of osteoclast differentiation factor at the pressure side of periodontal tissue and time distribution characteristics. RESULTS AND CONCLUSION:Compared with the control group, the number of positive osteoclasts and mRNA expression of osteoclast differentiation factor at the pressure side of the alveolar bone tissue were increased with orthodontic time, reached the peaked at 7 days and then gradualy decreased. The number of positive osteoclastsand mRNA expression of osteoclast differentiation factor at the pressure side of the alveolar bone tissue were significantly higher in the Damon Ⅲ group than the other three groups at 7 days after orthodontic treatment (P < 0.05). These findings indicate that, during the bone remodeling, the number of positive osteoclasts changed in accordance with the mRNA expression of osteoclast differentiation factor, and at 7 days, the number of positive osteoclasts and mRNA expression of osteoclast differentiation factor were highest in the Damon Ⅲ group.

BACKGROUND:There is no design that can completely rule out the intermittent impact damage to implants, therefore, a new bal attachment-retained implant system is constantly updated and developed. OBJECTIVE:To evaluate the clinical effectiveness of an implant-supported mandibular overdenture retained with a bal attachment. METHODS: We searched the Cochrane Library, PubMed, Medline, EM-base, WanFang Data, CNKI, VIP and other databases by computer to colect randomized controled trials addressing the implant-supported mandibular overdenture retained with a bal attachment and other control methods for dentures. The time limit was from database creation to February 2014. Two researchers independently completed literature screening according to inclusion and exclusion criteria, data extraction and quality assessment. RevMan 5.1 software was used for meta-analysis. RESULTS AND CONCLUSION: There were 10 studies included in result analysis, including 7 from China and 3 from other countries. Analysis results showed that statistical heterogeneity was remarkable in included studies, and there was no significant difference in patient’s satisfaction, clinical and objective indicators, and complications, suggesting that this approach continues to be explored in clinic. The implant-supported bal attachment-retained mandibular overdenture is relatively expensive, which is identical with the current research progress that is in the exploration stage worldwide. Due to the limited quantity and quality of included studies, the conclusions of this systematic review only provide references for clinical practice and research. The implant-supported bal attachment-retained mandibular overdenture stil needs further exploration and improvement.
