Immediate Implant Placement in the Molar Regions

The purpose of this study is to look at the bonehealing when a molar has been extracted and immediately replaced by an implant leaving some defects around the implant.

The defects are being treated in three different with the hypothesis that the three ways of treatment result in equal bonehealing.

About this study

This study is a randomized clinically controlled study with three group of each thirty patients, where the bonehealing after immediate implantplacement in molarregions is being investigated.

Totally 90 patients are going to get a molar tooth extracted and immediately replaced with an implant (Brånemark System, Wide Platform). The molar tooth should be in such a condition that is has to be extracted.

Extracting a molar leaves a defect which cannot completely be filled out by an implant. The 90 patients are therefore randomised into 3 groups according to how the perimarginal bonedefects around the placed implants are being treated: 1. Bonechips 2. Membrane 3. Bonechips+Membrane. The bonehealing of the defects around the implants are then compared the groups in between. The amount of newly formed bone is being estimated too by digital radiography and subtractionradiography. Furthermore the prognosis for immediate placed implants in molar regions in relation to the method of defectreconstruction one year after crown delivery is also being investigated. All the investigations are conducted with the Ho-hypothesis that there is no difference in the bonehealing the three groups in between.
