Graftless Maxillary Sinus Lifting with Simultaneous Dental Implant placement in Extraction Socket and Edentulous Ridge: A prospective Clinical Study
##plugins.themes.bootstrap3.article.main##
Abstract
Aim: The present study aimed to evaluate the amount of bone formed after graftless maxillary sinus lifting procedure in edentulous ridges compared to newly extracted teeth sites when a simultaneous dental implant planned to be inserted.
Subjects and methods: Twenty patients who needed dental implant in the posterior maxilla having a reduced vertical bone height were divided into two groups, fresh extraction socket group (10 cases) and patients with edentulous ridges at the site of indicated implant. All implants were from the same company with the same diameter and length. Dental Cone Beam Computed Tomography (CBCT) examination was performed to assess the bone gain height radiographically at 6 months after surgery.
Results: The mean height of sinus elevation in extraction socket group was statistically significant higher than edentulous ridge group (4.02±0.84 and 2.63±1.56; respectively, P=0.023). Percentage change in the edentulous ridge group was (56.79±40.33), which is higher than that of extraction socket group (29.79±23.68) yet the difference was not significant (P=0.085).
Conclusion: Dental implants at the site of pneumatized bone with simultaneous sinus lifting without bone graft showed a good and successful outcome in regard to bone gain and increased bone height with the fresh extraction socket cases.
