Summary

Short-term comparison of clinical application effects of Astra OsseoSpeed EV short implants and conventional implants for maxillary sinus elevation

Detailed description

1. If the survival rate, marginal bone resorption , complications and patient satisfaction of the short implant group are comparable or better than those of the conventional implant group, then short implants can be regarded as an effective treatment option for insufficient alveolar bone in the posterior teeth area. Thus, in clinical practice, the investigators can utilize short implants combined with transcrestal sinus floor elevation, or even implant short implants to help patients with certain insufficient maxillary bone complete implant restoration without resorting to more complex, costly and more invasive external elevation surgery to increase the length of posterior teeth implants in the maxillary region. 2. If it is found that the short implant group has a higher incidence of complications or a lower long-term survival rate, further exploration of its indications and optimization of surgical strategies is required.
