Autotransplantation and Enamel Matrix Derivatives Case Series (ATTCS)
Efficacy of Digitally Tooth Autotransplantation With Adjunctive Use of Enamel Matrix Derivatives (EMD): A Prospective Case Series
The goal of this prospective case series 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 is:
- What is the benefit, in terms of clinical attachment level, of using enamel matrix derivatives adjunctive to tooth autotransplantation?
Participants will be subjected to a digitally protocol of tooth autotransplantation.Only one group (test) is assessed. It will be supplemented with the application of enamel matrix derivatives before the placement of the transplanted tooth into the surgically produced alveolus.
Study Overview
Detailed Description
All surgical treatments will be performed by the same experienced periodontist (IP) after the administration of local anesthesia. Initially, tooth sectioning of the hopeless tooth (receptor) will be carried out using fissure carbide burs, and the remaining fragments will be extracted as minimally invasively as possible. A tooth-supported surgical guide will be used to prepare the recipient site following the 3D planning. Additional alveoloplasty procedures will be performed with round diamond burs if necessary to adapt the computed aid rapid prototyping (CARP) model to the virtual planning position. The donor tooth will be extracted as atraumatically as possible, utilizing a piezoelectric surgical instrument if osteotomy is required, and avoiding the use of elevators or forceps over the root surface. Extraorally, EMD will be applied to the root surface of the donor tooth.
After positioning the donor tooth onto the surgically created recipient bed, a semi-rigid orthodontic wire will be used to splint the tooth to the mesial and distal adjacent teeth, and sutures will be applied to closely adapt the soft tissues around the autotransplanted tooth. Occlusal adjustments will be made if necessary. Alternatively, orthodontic composite bite stops will be placed on top of adjacent teeth to obtain temporary dental disocclusion.
