Description
Technical Field
The utility model belongs to the technical field of the planting of oral cavity wicresoft, especially, relate to a temporary planting body suitable for bone increment is planted in oral cavity.
Background
With the improvement of living standard of people, more and more edentulous patients select the planting and repairing scheme. The implant restoration not only provides ideal support and retention for the false tooth, but also has the advantages of beautiful appearance, comfort, no need of grinding healthy abutment teeth and the like. The oral implant is divided into three parts of an abutment, a neck and a body from outside to inside. Wherein, the abutment is directly connected with the artificial denture, and the body part is embedded into the alveolar bone and compatible with the bone tissue; the abutment is connected to the body through the neck. The key to successful implantation is sufficient alveolar bone mass, however, there are several factors that lead to insufficient available bone height or width or both at the implant site clinically, resulting in insufficient implant surface exposure and/or initial implant stability when the implant is implanted at the correct site and dimension.
Cause the not enough reason of patient's alveolar bone volume mainly for patient's jawbone and the tooth body receive damage under the exogenic action, tooth extraction, tooth implantation restoration time overlength etc. during oral disease patient's treatment, can lead to patient's alveolar bone to take place the excessive absorption, the atrophy condition under these factor effects, and then cause the bone volume to reduce and be not enough to accomplish the problem of planting regional tooth body and planting the operation.
For the oral implant patients with serious insufficient alveolar bone width and height, bone powder is implanted by bone expansion surgery or guided bone regeneration surgery (GBR) to increase alveolar bone mass. However, the implant implanted in the same period of the bone augmentation surgery increases the risk of infection, and due to poor biocompatibility between the implant and the alveolar bone, immediate stable connection cannot be realized, so that the initial stability of the oral implant in the oral cavity is poor, and the implant may fail to form osseointegration.
To the serious not enough patient of the tooth district bone height behind the maxilla, often need to adopt the dual-phase operation mode of postponing implanting after the maxillary sinus promotes for improving the operation success rate, carry out the maxillary sinus and promote the bone grafting earlier promptly, treat that the wound seals the bone healing period of 6 months or even longer time, implant the operation again. However, if the implant is implanted after the bone augmentation surgery is performed for half a year, the bone augmentation surgery may not be effective and the desired alveolar bone width and height may not be obtained.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a temporary planting body suitable for oral cavity planting bone increment implants this temporary planting body in bone increment operation synchronization, not only can regard as the support to maintain the bone grafting space, and simplifies secondary operation process, reduces the infection risk, simple structure, low cost.
Solve technical problem above the utility model provides a temporary planting body suitable for oral cavity planting bone increment, its characterized in that: the lower part of the bone and the gum penetrating part are arranged and are connected into a whole up and down; the gum penetrating part is provided with an implant top end and a neck which are connected into a whole from top to bottom, the lower part of the bone is provided with an implant bottom end and a bone body, the outer surface of the bone body is provided with threads in a surrounding manner from top to bottom, and the bone body and the implant bottom end are connected into a whole from top to bottom; the outer surface of the gum penetrating part is smooth.
