[A clinical report of partially debonded adhesion fixed metal splint repaired with adhesion-mechanically fixed metal splint].
METHODS
The patient was 60-year-old male whose chief complaint was esthetic problem due to median diastema. After orthodontic treatment, an adhesion-fixed metal splint was placed to retain 3-3. After 11 months, the metal retainer on 3 partially debonded. The retainer on 3 was removed and 3 was connected to 4 with an adhesion-mechanically fixed metal splint. Six months later, 3 was separated from 2+2 and connected to 4 5 with the conventional crown restoration.


CONCLUSIONS
The prognosis is good. This result is attributed to the decrease of splint length and the application of the adhesion-mechanical retainer. These seemed to increase the rigidity and prevent deformation of the splint, thus reducing tensile or shear stress applied to the adhesion interface and improving the bonding durability.


CONCLUSIONS
This clinical case suggested that the range of splinting and design of retainer affect the durability of adhesion-fixed metal splints.
