Digital workflow for fabricating an overdenture by using an implant surgical template and intraoral scanner

Implant-supported overdentures can significantly increase function and satisfaction during the first year and can last for 5 to 10 years. The 2-implant-supported mandibular overdenture is recommended as a standard treatment for edentulous patients. In the recent years, studies have reported the use of digital complete dentures. However, as a modified technique for complete dentures, few studies have evaluated the use of digital techniques in the fabrication of overdentures. The purpose of this article was to introduce a digital workflow for fabricating overdentures by using information from the existing dentures.
