Soft tissue form around it, patient can voluntarily pluck a kind of dummy worn." fixed denture " be repair denture in one or
The dummy of several missing tooths, one is connected in the ready abutment in missing tooth both sides or planting body by binding agent or fixing device
Rise, so as to recover the anatomic form of missing tooth and physiological function.Worn because this dummy patient can not voluntarily take, Gu referred to as
Fixed denture, and because its structure is similar to bridge, therefore also known as fixed bridge." implant denture " refers to the alveolar bone in oral cavity edentulous region
It is implanted into planting body（Artificial tooth root）, after planting body survives, then the reparation that dummy completes implant denture is made in its upper end.
" supporting tissue " refers to chondroid tissue, the shortage matrix compared with common cartilage, is imbued with cell, cell is larger, transparent in hyaloid
Utricle shape.
Because dental caries are bad, periodontosis, injure the reasons such as developmental deformity outside and cause the situation of absence of tooth, in clinical oral diagnosis and treatment
It is extremely common.Absence of tooth can seriously affect chewing, pronunciation, the face even mental health of patient.It is clinically main at present
