Minimally invasive maxillary sinus augmentation for single dental implant restoration: a case report

This clinical case aims to report a minimally invasive approach for maxillary sinus augmentation for first-molar replacement with a dental implant. A 61-year-old male presented to dental clinic with missing upper right first molar. Panoramic x-ray (OPG) showed insufficient posterior maxillary bone with a residual alveolar bone height<4 mm. The patient underwent a minimally invasive sinus floor elevation and augmentation. Three months postoperatively, and a dental implant (? 4.1×12 mm, bone level, straumann) was placed successfully. Thereafter, at 3-months post-implantation, the final restoration was accomplished. A 12-months follow-up demonstrated satisfactory clinical outcome. In conclusion, the present case-report demonstrates the advantages of the presented technique for sinus augmentation and dental implant restoration with high precision and promising result, in similar cases with a residual alveolar bone height <5 mm.
