Tooth loss can have a considerable negative impact on a person’s quality of life. Specifically, tooth loss will damage a person’s eating ability, nutrition, appearance, speech, and self-esteem. The current dental treatments for replacing missing teeth are dentures, bridgework and dental implants. This case was more complex than usual with diverging implants and the desire to have it screw retained. By using Astra Tech Angled Abutments we were able to change the path of insertion allowing both the upper and lorew prosthesis to be made in once piece. The upper is a Zircon Zahn full zirconia framework with ceramic built on the labial and buccal surfaces to ensure an aesthetic result. The lower is also screw retained, but in this case, it is high impact denture teeth with processed high impact acrylic over a milled titanium framework.
