Introduction: In 1995, Block and Hoffman reported the successful use of a subperiosteal disk (onplant) to reinforce orthodontic anchorage in an experimental study in dogs and monkeys. It was concluded that onplants provide sufficient anchorage to successfully move and anchor teeth. Aims: The aim of this article is to discuss the development of onplant, key design features, clinical indications for use as well as any available supporting evidence. Methods: Review of the literature was carried out using the following search methods: MEDLINE and EMBASE. The search was focused on various keywords including: "onplant", "bone anchorage device" and "subperiosteal disk", which were conducted on studies published until January 2020. Results: Evidence from clinical studies is scarce, a total of 9 related papers were retrieved from the literature (2 animal studies, 3 RCTs, 2 case series and 2 case reports). All types of study designs were included in the summary to maximize potential information gain. Conclusion: In this article, we reviewed the development of onplant and outlined the general design features as well as specific design features. The onplant is no longer available in the market given that it never gained acceptance among the orthodontic community and its use is almost obsolete.
