Aims and objectives: According to ÖNORM H 6020 an ultra-clean air system (H1 area) is required at all implantations and all surgeries where bone is handled without distinguishing between localization. The new ÖNORM H 6020 also might be meaningful for dental surgery. The question is: Does the quality of the air in the operation area influence the success rate of implantations and augmentations? Background: The study included 19 patients with dental implantations and 15 patients undergoing augmentations at Bernhard Gottlieb Universitätszahnklinik in Vienna.
It was evaluated, if there were any surgical instruments that made contact with the mucosa and with the bone of the patient during the surgery.
Results: There was a contamination of the surgical instruments with the patients own oral microorganisms at all surgeries included in the study.
In every implantation and in every augmentation, there was at least one surgical instrument that made contact with the patients' mucosa and also with the patients' bone.
Conclusion: It seems that measures of asepsis have a wide influence to reduce post-operative infections. An ultra-clean air system appears to exert no momentous influence on post-operative infections at implantations and augmentations.
