Loma Linda Guide: A Stereolithographically Designed Surgical Template: Technique Paper
A new flapless technique based on a template fabricated from a stereolithographic maxillary model is presented in this article. The proposed concept can be used to accurately control the tridimensional position of the dental implant. The laboratory procedures involving the fabrication of the surgical template are described.Abstract
