简要总结
thirty implants will be inserted in patients seeking implantation of their lost posterior maxillary teeth (premolar and molars) with limited bone height below the floor of the maxillary sinus, secondary to sinus pneumatization. The patients will be selected from those attending the outpatient clinic of the Oral & Maxillofacial Surgery Department, Faculty of Dentistry, Mansoura University.

结局指标
主要结局
implant stability
时间窗: 9 months
the stability of the implants will be evaluated by RFA with the Osstell Mentor device.
Vertical bone height
时间窗: 6 months
vertical bone height will be measured as the distance from the alveolar crest to the new sinus floor at the middle of the implant
