Description

Dental implant operation drill

Technical Field

The utility model relates to a dental implantation surgical instruments field, concretely relates to dental implantation surgical drill.

Background

With the continuous development of dental implant, implant denture repair has gradually become an ideal treatment scheme for dentition defects and dentition deletion. It is well known that sufficient bone mass is the basis for ensuring successful implantation, but patients with clinical tooth loss are often accompanied by varying degrees of alveolar bone atrophy, requiring implantation with simultaneous bone augmentation using Guided Bone Regeneration (GBR) techniques.

At present, bone graft materials applied to GBR surgery mainly include autologous bones, allogeneic bones, xenogeneic bones, hydroxyapatite artificial materials and the like. Among them, autologous bone is known as "gold standard" in bone graft materials by virtue of good bone guiding and bone inducing ability, excellent biocompatibility, and the like. The autologous bone fragments have been widely used in the oral implant GBR surgery due to the unique advantages of simple material acquisition, no need of complex processing, flexible application, excellent performance and the like.

During the preparation of the cavity for the implant operation, a certain amount of autologous bone fragments are generated by cutting of the reamer, and a plurality of methods are adopted to effectively collect the bone fragments and apply the bone fragments to bone transplantation clinically at present so as to repair the bone defect around the implant. In the conventional flushing and cooling planting preparation hole process, the filtering type bone fragment collecting device can be adopted to collect the granular autogenous bones generated in reaming, the technical operation is simple and convenient, and the autogenous bones which can be absorbed along with cooling water originally are recycled. Research proves that the bone fragments collected by the negative pressure suction device matched with the filtering type bone collector have strong osteogenesis capacity, are practical and reliable for repairing and planting bone defects, can reduce the using amount of bone substitute materials, and increase the bioactivity of bone graft. In recent years, researchers in China have developed such devices and applied them to clinical applications.
