This systematic review presents the loading protocols applied when using implants and/or screws in orthodontic treatments.
Clinical trials which assessed the use of implants and/or screws for orthodontic anchorage and studies involving treatment on syndromic patients, surgery, other simultaneous treatments, or appliances (ie mini-plates) were considered. Electronic databases (Medline, Medline In-Process & Other Non-Indexed Citations, Lilacs, Pubmed, Embase, Web of Science, and All Evidence Based Medicine Reviews) were searched with the help of a senior Health Sciences librarian. Abstracts which appeared to fulfill the selection criteria were selected by consensus. The original articles were then retrieved and evaluated with a methodological checklist. References were also hand searched for possible missing articles.
Eleven articles fulfilled the selection criteria established. Five studies involved the use of implants while six involved the use of screws for orthodontic purposes. An individual methodological analysis for each article was made.
Loading protocols for implants involve a minimum waiting period of 2 months before applying orthodontic forces while loading protocols for screws involve immediate loading or a waiting period of 2 weeks to apply forces. Success rates for implants were on average higher than for screws.
本系统评价介绍了正畸治疗中使用种植体和/或螺钉时所应用的加载方案。
纳入评估种植体和/或螺钉用于正畸支抗的临床试验，以及涉及综合征患者治疗、手术、其他同期治疗或矫治器（即微型钢板）的研究。在一位资深健康科学图书馆员的帮助下，检索了电子数据库（Medline、Medline在研及其他未索引引文、Lilacs、Pubmed、Embase、科学网和所有循证医学综述）。通过共识选择似乎符合入选标准的摘要。然后检索原始文章并用方法学清单进行评估。还手动检索参考文献以查找可能遗漏的文章。
11篇文章符合既定的入选标准。5项研究涉及种植体的使用，6项涉及螺钉用于正畸目的的使用。对每篇文章进行了单独的方法学分析。
种植体的加载方案要求在施加正畸力之前至少等待2个月，而螺钉的加载方案涉及即刻加载或等待2周后施加力。种植体的成功率平均高于螺钉。
