Objectives: The aim of this study is to evaluate the complications with the elevation of maxillary sinus bottom in dental implantation and identify the factors, that may contribute to the occurrence of these complications, and propose different therapeutic approaches. Material and methods: The studied population has consisted of 685 patients (971 sinuses) with severe posterior maxillary atrophy treated with sinus bottom elevation by means of the lateral window access by one/two stage technique. For unilateral procedures 399 patients have been appointed and for bilateral procedures – 286 patients. The sinus elevation has been performed with the usage of deproteinized bovine bone material (DBBM) only or its 1:1 mixture with autogenous bone as well as β-tricalcium only or its 1:1 mixture with autogenous bone. The complications have been evaluated clinically and radio graphically. Results: The most common intraoperative complication has been the sinus membrane perforation which has been observed in 44 sinuses operations (4.5%). Severe intraoperative bleeding has been observed in 42 operations on sinuses (4.3%), 22 sinuses (2.3%) of 22 patients have acquired sinus graft infection, twelve of the patients have been smokers. The implant migration into maxillary sinus has been reported in two cases (0.2%). Wound dehiscence has been observed in 13 cases (1.3%). Periimplant infection has been observed in 23 patients with 54 implants, 8 of them have been removed (0.67%). Conclusion: The clinical outcome confirms the fact that sinus bottom elevation to improve the conditions for installing the dental implants can be considered as a safe treatment with a low frequency of complications. Proper patients’ selection and treatment planning as well as the application of the sinus elevation technique are the prerequisites to minimize the risk of complications. |
