Effectiveness of Contour Augmentation with Guided Bone Regeneration: 10-Year ResultsV. Chappuis, L. Rahman, R. Buser, S.F.M. Janner, U.C. Belser, D. Buser, 2017

AIMS

SURGICAL APPROACH

CLINICAL AND AESTHETIC PARAMETERS: STABLE OVER 10 YEARS

SUCCESS RATE OF 95% AFTER 10 YEARS

Assess the effectiveness of early implant placement with

simultaneous contour augmentation

Single-tooth, aesthetic zone

Flapless extraction, 8 weeks of tissue healing, placement of a bone level implant.

GBR with 2-layer composite graft (autogenous bone, Geistlich Bio-Oss®) and Geistlich Bio-Gide®.

Improvement: probing depth, significant decrease from 4.5 mm to 4 mm

Facial bone wall thickness 0 mm at surgery to 1.67 mm at 10 years.

High PES and WES aesthetic scores.

The CBCT analysis of the facial bone wall demonstrated that 19 of 20 implants (95%) had a detectable facial bone wall.NB. One implant ‘regenerative failure’: The patient had a history of smoking and was taking bisphosphonates due to osteoporosis. At the 10-year examination, the implant was clinically healthy without signs of infection but revealed no detectable facial bone.
