Efficacy of Nasal Floor Augmentation on the Survival Rate of Dental Implants: A Systematic Review.

Aim: To systematically review the existing scientific literature, to summarize and assess the efficacy of the nasal floor augmentation on the survival rate of dental implants by systematically reviewing the available literature.

Methodology: Review was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines and registered in PROSPERO-CRD42027289143. Electronic databases like PubMed, google scholar and Ebsco Host were searched from 2000 to December 2021 for studies reporting efficacy of nasal floor augmentation and reporting outcomes in terms of survival rates of dental implants. Quality assessment of included comparative follow-up studies was done using the critical checklist put forward by the Joanna Briggs Institute (JBI) was used.

Results: Only nine studies fulfilled the eligibility criteria and were included in the qualitative synthesis. Of those nine studies, five were case reports and four comparative follow-up studies. A total of 14 implants were placed in five patients with a survival rate of 100% in included case reports, while a total of 408 implants were placed in 130 patients with survival rates ranging from 89% to 100% in included comparative follow-up studies. No complications were observed during follow-ups, and the patients were satisfied with the functional and aesthetic results of the treatment. Quality assessment of included studies showed moderate to low risk of bias with overall high quality of studies.

Conclusion: The results of this systematic review indicate that implant placement by nasal floor augmentation techniques can be considered as a predictable treatment modality. However, due to the scarcity of literature, more studies should be carried out on proving the efficacy of nasal floor augmentation on survival rate or success of dental Implants.
