Background summary
Post extraction sockets in the esthetic area have been subject of discussion
among clinicians for many years. Buccal bone changes, its consequences for soft
tissue changes and finally it*s impact on the esthetic outcome has been
described in the literature by different research groups. Yet immediate implant
placement with correct implant positioning can play a positive role to achieve
a high-end esthetic result and reduce or inhibit the resorption of the buccal
bone.
Study objective
The primary purpose of this study is to investigate whether immediate implant
placement, in ideal position, might preserve soft and hard tissue shape and
contours, avoiding the need for extended augmentation and as a result achieving
better esthetic outcomes. Hypothesis of this study is to have significantly
less alveolar ridge resorption (<1.5mm in vertical and <3mm in horizontal
plain) when implants are inserted immediately after extraction in the correct
position in relation to residual buccal bone conducting computer guided
surgery, achieving acceptable esthetic results.
The secondary purpose of this study is to examine the precision of the
computerized guided surgery to insert implants in the fresh extraction sockets
to achieve correct 3D implant positioning.
Study design
This is a randomized, open interventional clinical trial in which 2 (widely
accepted) treatments will be compared to eachother.
Intervention
Randomized assignment to treatment group
Study burden and risks
The patients do not have to come to ACTA for more or less control visits than
usual. The risks are not different or greater than those of a treatment outside
of the study.
