A Phase 4 interventional study of Emdogain (EMD) - test and Sham group in Autotransplantation, Emdogain and Autologous Transplantation, sponsored by Universidad Complutense de Madrid. Recruiting at 1 site in Spain. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2024-05-09.

The goal of this randomized clinical trial is to compare the adjunctive use of enamel matrix derivatives in the treatment of tooth autotransplantation in terms of clinical attachment level. The main question it aims to answer. What is the benefit, in terms of clinical attachment level and probing depths, of using enamel matrix derivatives adjunctive to tooth autotransplantation? Participants will be subjected to a digitally guided surgery of tooth autotransplantation. The protocol of the test group will be supplemented with the application of enamel matrix derivatives before the placement of the transplanted tooth into the surgically produced alveolus.
Universidad Complutense de Madrid is the lead sponsor of 200 studies on the registry; 60 are open to participants now.

Inclusion Criteria: Adult patients attending the University Complutense of Madrid for dental treatment were eligible to participate in the study if they met the following criteria:
Exclusion Criteria:
Biological: Emdogain (EMD) - test · Procedure: Sham group
Procedure: Sham group
Initially, tooth sectioning of the hopeless tooth (receptor) will be carried out using fissure carbide burs, and the resulting fragments will be extracted with a minimally invasive approach. A multiple drilling axis tooth-supported surgical guide will be used to prepare the recipient site in accordance with the 3D planning. Additional alveoloplasty procedures will be performed with round diamond burs if necessary to adapt the computer assisted rapid prototyping (CARP) model to the virtual planning position. The donor tooth will be extracted as atraumatically as possible, utilizing a piezoelectric if ostectomy is required, and avoiding the use of elevators or forceps over the root surface. Extraorally, (Emdogain) EMD will be applied to the root surface of the donor tooth. Sutures will be applied to closely adapt the soft tissues around the autotransplanted tooth. A semi-rigid orthodontic wire will be used to splint the tooth to the mesial and distal adjacent teeth

Clinical Attachment Level
measured as the distance in mm from the CEJ to the bottom of the pocket will be the primary outcome of this study.
Time frame: through study completion, an average of 1 year
Radiographic bone level
Changes in marginal bone levels (MBLs), measured as the change in interproximal bone levels between 4 weeks after autotransplantation, six months and one year postoperatively. MBLs are defined as the distance between the cementoenamel junction (CEJ) and to the crestal bone level at the mesial and distal aspect . These measurements will also be recorded at the adjacent teeth/implants. For standardization of the radiographic technique, a customized bite block will be constructed for each patient using a parallel technique X-ray film holder (i.e.Rinn System, x-ray system or similar) and heavy silicone. The obtained digital radiographs will be evaluated using the image software (OsiriX Imaging Software, Geneva, Switzerland), with previous calibration of the images by inserting a small metal object of known measures in the bite block
Time frame: through study completion, an average of 1 year
Digital image assessment. Position of the Alveolar Ridge Measurements
For each patient, the baseline and the last follow-up visit STL files and Digital Imaging and Communications in Medicine (DICOM) files will be superimposed for best-fit alignment. Alveolar ridge width changes will also be evaluated at the buccal and lingual mesial, mid, and distal sites. A sagittal section at each area of interest will be made. Horizontal alveolar ridge width linear changes will be quantified in mm at three predetermined reference points established at 1, 3, and 5mm from the baseline gingival margin.
Time frame: at the study completion. an average of 1 year
