Abstract
BackgroundRemoving a tooth from the jaw results in the occurrence of oroantral communication in beneficial anatomic conditions or in the case of a iatrogenic effect. Popularized treatments of the oroantral communication have numerous faults. Large bone defect eliminates the chance to introduce an implant. Purpose of this work was assessment of the usefulness of autogenous bone graft and PRF in normal bone regeneration in the site of oroantral communication.Material and MethodsBone regeneration in the site of oroantral communication was assessed in 20 patients. Bone defects were supplemented autogenous bone graft from mental protuberance in 14 cases and from oblique line in 6 cases. The graft was covered with a PRF membrane.ResultsIn the study group in all cases closure of the oroantral communication was observed. The average width of the alveolar was 13 mm and the average height was 12.5 mm. In 3 patients an average increase of alveolar height of 1.5 mm was observed.ConclusionsThis method may be the best option to prepare alveolar for new implant and prosthetic solutions. Key words:Oroantral communication, oroantral fistula, autogenous bone graft, bone regeneration, platelet rich fibrin.
Highlights
Nowadays a lot of space is devoted to augmentation procedures regarding various types of surgical treatments, such as cystectomy, resection, extraction, pre-implantation treatments
Traditional methods to close oroantral communication, which occur after removing a tooth from the jaw, performed directly or as a stage of surgical treatment of chronic maxillary sinusitis with plastic surgery of oroantral fistula involve the use of patches formed from soft tissue and their tight suturing
In the light of recent studies and opinions, an oroantral fistula should be closed in 24 hours
Summary
Nowadays a lot of space is devoted to augmentation procedures regarding various types of surgical treatments, such as cystectomy, resection, extraction, pre-implantation treatments. Traditional methods to close oroantral communication, which occur after removing a tooth from the jaw, performed directly or as a stage of surgical treatment of chronic maxillary sinusitis with plastic surgery of oroantral fistula involve the use of patches formed from soft tissue and their tight suturing. This procedure results in shallowing of vestibule and abnormal bone remodeling in the site of the oroantral defect which makes future prosthetic or implant and prosthetic treatment difficult or impossible. Of autogenous bone graft collected from the mandible in the area the oblique line and mental protuberance, and platelet rich fibrin in normal bone regeneration in oroantral communication
