Les petits moyens en chirurgie préimplantaire

Osteotomes, the bone scraper, and the bone trap are simple tools used for preprosthetic surgery. They are not very invasive, present little risks, and they can be used in private surgical practice with local anaesthesia. The osteotome preserves, dilates, and condenses the alveolar bone instead of eliminating it like drilling does. It does not require any motor or irrigation. It increases the width and the height of the alveolar crest. It allows the localized expansion of narrow or misshapen alveolar crest when its width ranges between 3 and 4.5 mm. It also allows performing a localized sinus lift, when the sinus floor height ranges between 4 and 8 mm. The bone scraper is used to retrieve cortical chips of parietal bone for sinus lift. The bone trap is connected to the suction tube. It is used to collect bone powder after milling or bone drilling. These simple tools should be available for all maxillofacial surgeons in specific indications.
