## 1 Introduction  
Over the past two decades, temporary anchorage devices (TADs) have become important and essential armamentariums in orthodontic practice. TADs are now recognized as one of the most effective ways to conserve anchorage and move dental units in such a way as to reduce the need for extraction and surgical treatments [1, 2]. Root collusion issues during TAD placement and surgical trauma have adversely affected the use of TADs [3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13]. One of the solutions for the safe placement of TADs is to follow step-by-step procedures and use surgical guides, which is possible with technological innovations. Most of the pioneers of surgical guides arise from those using the dental implant, a technique that has been used for decades [14, 15, 16]. A surgical guide for inserting single-standing TADs facilitates placement and is integral to safe clinical practice. Creating and making a surgical guide has become possible with the advanced application of CAD/CAM technology and the affordability of 3D printers [17].  
This paper covers two main topics: the importance of using a surgical guide for TAD implantation and the process of creating the guide.  
There have been numerous papers discussing the issue of TAD usage successes and failures. One of the critical areas is the placement itself, causing trauma to the tooth's root and damaging the periodontal membrane [18]. Such unwanted complications happen, especially in inter-root implantation. The average TAD's diameter is between 1.4 to 1.8 mm, and, often, the interdental bone may not be available to accommodate these dimensions [19, 20, 21].  
The placement of TADs is required to be either in interdental bone or other safe anatomical sites of the maxilla and mandible. Accurately placing TADs without hindering dental roots and other structures is crucial for their safety and stability during dental movements. By having complete control over the placement, an orthodontist can conduct orthodontic biomechanics in an organized and optimized manner, resulting in reduced treatment duration and better quality of treatment outcome [22].  
According to studies, implants placed using the freehand method had significantly higher errors. The risk of positioning errors was as high as 88% when using the freehand method. At the same time, single-type, mucosa-supported guides had the lowest error rate of only 6%, even when other factors were considered [23]. Orthodontists had the opportunity to learn from the past when prosthodontics and other disciplines started using surgical guides for dental implants [24; 25; 26]. A surgical guide for TADs is intended to reduce orthodontist challenges, and designing the procedure for practical use in daily orthodontic practice will benefit patients and the orthodontist practitioner.  
The benefit for patients is less trauma and shorter surgical appointments. Using a surgical guide to place TADs precisely allows for accurately preparing a post-insertion appliance in the laboratory. The laboratory personnel must discuss with the orthodontist to ensure the success of the surgical guide. After the TAD insertion procedure, the post-insertion appliances, which are ready beforehand, are issued in the same appointment. The system using CAD/CAM metallic-printed appliances has been used as an example with a resin surgical guide [27; 28; 29].  
The system will enable the transfer of the predetermined planning to placing the TADs. The same method can involve several TADs, making them parallel or placed on predetermined angulation when needed. The advantage of the system is to place an appliance immediately after the TADs' placement, as noted above. The system allows a possibility to elevate the search for dentofacial orthopedics to the next level, such as distraction osteogenesis, which is relatively less invasive than surgical orthodontics but may need complex design as several TADs should be placed accurately.
