Abstract
|
|
|
There are some similar aspects at histological and morphological characteristics between the peri-implant tissue and
periodontal tissue and the direct attachment between the titanium and soft tissue around the implant called as "Functional
ankylosis" can prevent the apical infiltration of inflammatory and bone resorption around implant. But, the repeated
connection and disconnection of the abutment can destroy the mucosal barrier of soft tissue around the implant and can
cause the marginal bone resorption. The amount of marginal bone resorption may reduced if the prosthetic abutment is
placed at that time of surgery. Connection of the prosthetic abutment at surgery was limited because the low accuracy of
conventional method, but by using of Cone Beam Computed Tomography(CBCT) and guide surgery, the 3-dimensional
accuracy of implant placement became much higher than before and it became possible. This is a clinical case of immediate connection of prosthetic abutment and provisional restoration by using of precise CBCT diagnosis and pre-fabricated zirconia customized abutment at surgery and the alternative method is described in this article because of the clinically contentable results.
