An observational study of Traumatic Dental Injury and Tooth Aplasia, run by MKG-Praxisklinik at 1 site in Germany.
Trial summary
Objective: Premolar autotransplantation represents an effective therapeutic option for the treatment of juvenile dentition in traumatic dental injury with tooth loss.

About this study
Objective:
Premolar autotransplantation represents an effective therapeutic option for the treatment of juvenile dentition in traumatic dental injury with tooth loss. Numerous studies report on the osteoinductive potency of the method, however, to date no quantitative data has been provided. The objective of this prospective clinical study was to quantitatively assess the bone and soft tissue levels after autogenous premolar transplantation by clinical and radiographic parameters.

Materials/Methods:
In the study 26 premolars were transplanted in 20 patients after traumatic dental injury (n=10) or tooth aplasia (n=16) in the upper front. Standard clinical parameters were evaluated. Based on a standardized photo documentation, the relative soft tissue level was measured in comparison to the healthy adjacent teeth. Radiographic findings involved the evaluation of root resorption, pulp canal obliterations and the relative bone height. Patient satisfaction was determined using a standardized questionnaire.

Questions about this trial
What is this clinical trial studying?
An observational study of Traumatic Dental Injury and Tooth Aplasia, run by MKG-Praxisklinik at 1 site in Germany.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 15 Apr 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Transplant survival (time frame: 2006-2014). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Apr 2016; AzTrials last refreshed its copy on 8 Nov 2026.
