Analysis of factors related to complications of transalveolar technique for sinus floor elevation
In cases of insufficient bone in the maxillary posterior region,the transalveolar technique is a common,safe,and effective method to increase the amount of bone required for implantation.However,this technique may also lead to various intraoperative and postoperative complications.Clinicians need to pay attention to various risk factors to minimize the incidence of complications.The purpose of this article is to discuss the risk factors associated with complications of internal sinus floor elevation,which are categorized into intraoperative and postoperative complications.The most common intraoperative complications are perforations of the sinus floor mucosa and ectopic insertions of implants into the sinus.Postoperative complications,such as maxillary sinus infection and postoperative maxillary sinusitis,displacement of implants after surgery,and benign paroxysmal positional vertigo(BPPV),deserve more attention.Given these complications,this article provides a detailed description of the risk factors,hoping to help clinical doctors in using the internal sinus floor elevation more safely and effectively in the clinic.
