Description
Technical field
The present invention relates to Synostosis artificial tooth, more particularly, relate in the Synostosis artificial tooth (Osseo-Integrated Dental Implant) that is formed with the grinding band that highly grinds, can enlarge the Synostosis artificial tooth of the contact amount and the reinforcement structural strength of bone.
Background technology
Synostosis artificial tooth also is called endosteal implant (Endosseous Implant), because higher clinical success rate and the outstanding property on the masticatory function, clinical practice increases day by day.
But, in the successful clinically Synostosis artificial tooth, also because bone merges not exclusively or produce osteoclasia at the cervical region of Synostosis artificial tooth, thereby the frequent failure that produces Synostosis artificial tooth estimates that the patient who will suffer hardships owing to the pathological changes around this Synostosis artificial tooth from now on can increase.
Though the failure of Synostosis artificial tooth results from the small fracture repeatedly that is applied to the mistake load on the artificial tooth or the multiple reasons such as bacterial infection of artificial tooth's periphery, irrespectively all will pass through bone regeneration around implant inflammation (Peri-implantitis) with reason.This bone regeneration around implant inflammation causes the exposing and the loss of cervical region Peripheral Bone etc. of cervical region of damage, the Synostosis artificial tooth of the inflammation of alveolar mucosa and attached gingiva clinically, therefore in order to keep the function of Synostosis artificial tooth, the bone regeneration around implant inflammation needs the initial stage suitably to treat.
In the past, for initial stage treatment bone regeneration around implant inflammation, around Synostosis artificial tooth, carry out periodontal and strike off valve surgery, and remove toxin on the root of the tooth face be formed at the Synostosis artificial tooth that exposes in pollution, and the jog of the face of removing the thread structure of implant surface and plasma surface, covering with hydroxyapatite etc., and highly grind this face.
But, in the treatment of existing bone regeneration around implant inflammation, be the unusual Therapeutic Method of difficulty with Synostosis artificial tooth with striking off surfaces contaminated that utensil or dental height cutter accurately grind the gingiva interior section at the root of the tooth position of Synostosis artificial tooth.And, in the occasion of existing Synostosis artificial tooth, when the cervical region of Synostosis artificial tooth produces bone injury, since the coarse surface characteristic of Synostosis artificial tooth, the problem that exists osteoclasia and inflammation to spread rapidly downwards.
