Abstract

Abstract: Objective: To evaluate the clinical effect of maxillary sinus floor elevation through controlling the tension of maxillary sinus mucosa. Methods: A total of 40 patients received the maxillary sinus floor elevation through controlling the tension of maxillary sinus mucosa from the top of alveolar or lateral window of the maxillary sinus,and the bone substitute material was placed instantly. The implants were placed simultaneously or in other time. The patients were analyzed by cone-beam computed tomography and evaluated by Visual Analogue Scale (VAS) and Verbal Rating Scale (VRS). The ISQ scales were compared between two groups. Results: Penetrating of sinus mucosa was observed in one case, but the case was successfully treated with absorbable collagen membrane (Bio-Gide). There was no complaining during two years following up. Significant statistic difference was found in the VAS and VRS (P＜0.05), however, not in the ISQ scale between two groups. Conclusion: Through controlling the tension of maxillary sinus mucosa, the maxillary sinus floor elevation was predictably simple and minimally invasive, and the satisfactory rate of patients was high.
