Does the quality of residual alveolar bone apical to a periodontal lesion beneath the maxillary sinus play a vital role in preventing the extension of periodontal disease to maxillary sinus? A CBCT-assisted retrospective study.

Background: The mucous membrane of the maxillary sinus is sensitivis susceptible to infection or inflammation adjacent to it, which may contribute to mucous membrane thickening (MMT). Residual alveolar bone quality (RABQ) is considered a quality of the remaining bone apical to periodontal defect adjoining to the floor of the maxillary sinus.

Objective: The current study aimed to analyze the minimum RABQ to prevent the extension of periodontal pathology from reaching maxillary sinus using cone-beam computed tomography (CBCT).

Is balloon-assisted maxillary sinus floor augmentation before dental implant safe and promising? A systematic review and meta-analysis.

We aimed to assess the complications of minimally invasive balloon-assisted maxillary sinus floor augmentation, compared with the conventional sinus floor augmentation procedures done before placing a dental implant. A structured question was formulated and an electronic search was conducted in three databases (MEDLINE via PubMed, Google Scholar, and Scopus). A separate search of gray literature and a hand search for missing articles were also conducted.
