Is it necessary to make a positioning guide for dental implants?

Guides are not required during the dental implant process.
The use of guides during dental implants depends on the situation. Generally speaking, the effect of using guides is better than not using them, but using guides will increase some preoperative costs.
Experienced doctors generally do not need guides for implants of single teeth or 2-3 teeth. However, for more complex tissue reconstruction, such as full-mouth implant dentures or multiple implant dentures, guides are generally used, because the intraoral field of vision changes during the implant process, which may hinder the direction of implantation, and the use of guides is more accurate.
Generally speaking, the guide is completed by computer based on the oral mucosal conditions shown in the CT results, which is more accurate. If the full mouth or multiple teeth are implanted, try to use guides. If a single or 2-3 teeth are implanted, and the doctor is more skilled in implantation technology, guides may not be used.
