The anchorage quality of titanium microplates with short microscrews for orthodontic anchorage applications.
OBJECTIVE
The aim of this clinical study was to assess the stability of titanium microplates with short microscrews for orthodontic anchorage applications.


METHODS
Eleven titanium microplates with short microscrews were implanted in nine patients for unilateral gap closure, and in one female patient with severe periodontal problems of the dentition for bilateral gap closure. After a healing period of 2-3 weeks the microplates were loaded with directly applied forces (150/200 cN).


RESULTS
All implanted microplates were clinically and radiologically stable. On explantation all microplates were firmly anchored in the buccal cortical bone.


CONCLUSIONS
To summarize, we have determined that titanium microplates with short microscrews meet all the requirements for osseointegrated anchorage. Furthermore, they have the advantage that the points of insertion in the upper and in the lower jaw can be very freely chosen without the risk of damaging adjacent anatomical structures.
