Abstract: Clinically, patients with a few tooth loss have serious alveolar bone absorption at the missing tooth site. When axial implants are used, bone grafting or maxillary sinus floor lifting should be used to increase the bone mass, but there is still the risk of perforation of maxillary sinus mucosa or injury to mandibular nerve canal. Some clinicians use inclined implants to reduce the trauma of bone augmentation surgery and shorten the repair period. However, the stability of tilted implants has always been the focus of attention. This paper collected the relevant literatures in recent years to discuss the factors affecting the stability of tilted implants.
