Objective: This work aims to investigate the effect of stripping of steep sheep maxillary sinus by using 0.012 or 0.014 model new-type memory elastic silk sleeve stripper and umbrella stripper.
Methods: Goats with sinus floor gradients of 60° to 90° were selected by computed tomography of sheep head. A total of 72 animal models were established and randomized into three groups (n=24): group A (0.012 model), B (0.014 model) and C (umbrella stripper). Alveolar and maxillary sinus mucosa were stripped after crowning, and stripping length was measured when the stripping limit was reached or mucosal perforation occurred.
Results: The average stripping length of mucosa in group A was 11.3 mm±4.6 mm, and three cases experienced perforation of sinus floor mucosa. The average stripping length of mucosa in group B was 17.5 mm±5.0 mm, and one case experienced perforation of sinus floor mucosa. The average stripping length of mucosa in group C was 4.2 mm±1.3 mm, and four cases experienced perforation of sinus floor mucosa. The difference among the three groups was statistically significant (P<0.01) according to variance analysis. Moreover, the comparison between any two means was also statistically significant according to Dunnett's T3 test (P<0.05).
Conclusions: The new-type memory elastic silk sleeve stripper effectively stripped steep maxillary sinus mucosa. The 0.014 model exhibited superior peeling effect and was relatively safe.

Dental implantation in the posterior maxilla is challenging due to anatomic proximity to the sinuses, relative bone quality, and pre-existing sinus diseases. An oroantral fistula (OAF) acts as a pathologic pathway of bacteria and can cause sinus infections and complicate dental implant management. Bony augmentation between the sinus floor mucosa and the oral mucosa at the OAF closure site is another critical consideration.

Objective: This study aims to determine the anatomical relationship between the posterior superior alveolar artery (PSAA) and the lateral wall of the maxillary sinus during preoperative radiological evaluations in the posterior maxillary dental region, as well as to evaluate the prevalence of PSAA and its potential associations with sinus pathologies.
Materials And Methods: This retrospective study is based on the analysis of Cone-Beam Computed Tomography (CBCT) data from 510 sinuses of 255 patients. The visibility of the PSAA vascular canal, artery diameters, vertical distance between the alveolar crest and the artery, and the distance to the sinus floor were measured in coronal sections.
The Repair of Large Maxillary Sinus Membrane Perforations with a Collagen Membrane Stabilized with Tacks on the Medial and Lateral Walls: A Technical Note.

Sinus membrane perforations are among the most commonly reported intraoperative complications encountered during maxillary sinus floor elevation procedures performed via the lateral window approach. Large perforations (> 10 mm) can pose a major clinical challenge, and often result in failed bone augmentation and poorer long-term implant survival. Owing to these challenges, even a highly skilled oral implant surgeon with advanced training in implantology faced with such perforations may abandon grafting procedures in favor of a reentry approach.

: Sinus lifting, a procedure to augment bone in the maxilla, may cause complications such as sinusitis due to impaired drainage. This study aimed to assess how sinus lifting impacts airflow in the sinus cavity, which is essential for patients undergoing dental implants. Using computational fluid dynamics (CFD), this research analyzed airflow changes after sinus floor elevation, offering insights into the aerodynamic consequences of the procedure.
