Description
Technical field
The invention belongs to oral cavity regenerative medicine field, more particularly to a kind of bioengineered tooth wears gum system.
Background technology
Bioengineered tooth, also makes clone's tooth or dental tissue engineering (Tooth Tissue Engineering) mean profit
With the means of in vitro and in vivo culture from the unicellular organizational project means for obtaining whole tooth.Because supporting tissue's construction is similar,
" bioengineered tooth " more easily can should jointly support fixed restoration with remaining other natural teeth in denture.Wherein made
Canine implant, also known as implant denture, it is a kind of bionical tooth being made of biomaterial, is divided into implantation human body jawbone
Act the planting body for supporting maintenance（Root of the tooth part）With the corona two parts for undertaking mastication.Doctor is lost after tooth according to patient
The change of alveolar bone and jawbone, is implanted into jawbone as artificial root of the tooth from the planting body of definite shape, then exposes mouth at it
Corona is installed on the implant post of intracavitary, the form and function similar to autologous tooth is obtained.
In recent years, with the development of oral cavity regenerative medicine, by the tissue engineering technique of seed cell combination timbering material
The regeneration of root of the tooth is realized on big animal model.But further to realize masticatory function, it is necessary to pass through the side of post and core crown
Formula carries out the reparation of corona, and this means that the pulp tissue of regeneration to be sacrificed, and needs model of being driven piles, produced, then
Hat reparation is carried out, is taken and complex operation.
And tooth implant is only and surrounding socket bone formation synosteosis, compared to natural teeth, the kind formed after synosteosis
Implant does not possess parodontium, the missing of this important feature, it is felt more blunt to stress and displacement, planting body is easy
By wound.
