Flapless Postextraction Socket Implant Placement, Part 2: The Effects of Bone Grafting and Provisional Restoration on Peri-implant Soft Tissue Height and Thickness- A Retrospective Study.
Int J Periodontics Restorative Dent. 2015 Nov-Dec;35(6):803-9. doi: 10.11607/prd.2178.
Abstract
This
article presents the results of evaluating the changes in peri-implant
soft tissue dimensions associated with immediate implant placement into
anterior postextraction sockets for four treatment groups: no BGPR (no
bone graft, no provisional restoration), PR (no bone graft, provisional
restoration), BG (bone graft, no provisional restoration), and BGPR
(bone graft, provisional restoration). The vertical distance of the
peri-implant soft tissue was greater for grafted sites than for
nongrafted ones (2.72 mm vs 2.29 mm, P < .06). The facial soft tissue
thickness at the gingival third also was greater for grafted than for
nongrafted sites (2.90 mm vs 2.28 mm, P < .008) and for sites with
provisional restorations compared to sites without them (2.81 mm vs 2.37
mm, P < .06), respectively. The net gain in soft tissue height and
thickness was about 1 mm. The increases in vertical and horizontal
dimensions for grafted sites were between 0.5 and 1.0 mm, as compared to
sites with no bone graft and no provisional restoration.
