Experience in the use of osteoplastic material Kollapan-L for perforation of the maxillary sinus

Abstract

The main complication that occurs during the operation of removing the teeth of the lateral group in the upper jaw is the perforation of the bottom of the maxillary sinuses. In such cases, the main method of treatment is plastic flap of soft tissue structures, however, the restoration of the resulting bone defect is often not considered. In this article, the issue of performing plasty of perforation of the bottom of the maxillary sinus with one-stage reconstruction of the bone tissue of the alveolar process with the osteoplastic material Kollapan-L was studied.The purpose of this article is to increase the effectiveness of surgical treatment of perforation of the floor of the maxillary sinus using the bone-plastic material Kollapan-L and an autoplasmic membrane.Materials and research methods. On the basis of the Department of Maxillofacial Surgery and Dentistry of the Clinic of the Samara State Medical University of the Ministry of Health of Russia, 56 patients aged 18 to 63 years were operated on. The gender difference was as follows: 32 women and 24 men. All patients were diagnosed with perforation of the floor of the maxillary sinus. Most of the patients initially applied for the extraction of the first or second molars in the upper jaw (47 people) and pushing the roots of the removed teeth into the floor of the maxillary sinus (9 people).Results and discussion. The obtained clinical results demonstrated that patients treated with osteoplastic material in combination with centrifuged plasma (main group) had a more stable postoperative period: edema was mild or absent, the facial configuration did not change.Conclusions. The analysis of the clinical results of treatment of 56 patients with perforation of the floor of the maxillary sinus demonstrated a high efficiency of using osteoplastic material in combination with the obtained plasma.
