Designing both mandibular central incisors on one 3.0-mm single-piece implant: Five years’ outcome

Abstract

Deficient bone volume, anatomical limitations, lack of available mesiodistal space, adjacent teeth angulations, and surgical errors may lead to placement of narrow diameter implants. In such a scenario, functional and esthetic—yet sustainable—replacement of more than one missing tooth becomes quite challenging. This article describes the successful restoration of missing both mandibular central incisors on one 3-mm single-piece implant in 3 patients. Despite being a biomechanically complex presentation, the objectives of optimal outcome were achieved in all 3 patients by means of innovative design, fine control of occlusal factors, and correct choice of restorative material. Until the last follow-up at 5 years, no implant or prostheses loss was experienced.
