Abstract
This current study was conducted to evaluate the efficacy of a new fiber glass splint i.e. (F-splint-Aid) for fixation of dentoalveolar fractures in children.
This study was carried out on ten children of both genders; all the patients had been subjected to trauma to periodontal supporting tissues or alveolar bone requiring treatment by closed reduction and fixation.
All the patients were treated under local anathesia by proper manual closed reduction of bone and repositioning of mobile, luxated, displaced and freshly avulsed teeth, followed by choosing the suitable teeth for splinting, cleaning of the lingual or buccal surface, polishing, etching by phosphoric acid, washing, drying, isolation and then cutting the fiber strip, impregnation with bond, firmly positioning, then light curing and finishing.
The patients were followed up clinically after 24 hours, on days 3 and 7 post operatively and then at weekly intervals for 6 weeks.
All patients were evaluated clinically regarding surgical technique, working time of application and removal of the splint, the effect on the gingival and periodontal tissue, post-operative occlusion and stability of fracture segments, Pain intensity, post-operative edema, mobility and vitality of teeth, and finally esthetic and patient satisfaction and ability to maintain oral hygiene.
Post-operative clinical follow up of the patients showed proper occlusion, no complications at any time of treatment, decrease in pain, edema and mobility from time of treatment to the seventh day post operatively which were statistically significant, and no signs of inflammation or infection.
After three weeks the proper bone healing was assured by detection of the stability of occlusion and the stability of reduced fractured bony segments, and then the strip at the interproximal was cut with a diamond bur, then the strip was removed from the abutment by a scalpel.
Post-operative radiographic follow up was done after one and four months post operatively and the bone density was measured using cone beam software. The results demonstrated that there were proper healing of bone and disappearance of fracture line, no signs of root or bone resorption or ankylosis, root development were not interrupted and there was a steady increase in the mean radiographic bone density which was statistically significant.
from the results of this study we conclude that fiber glass splint was proved to be cheap, easy, not time consuming in application or removal, noninvasive, well tolerated by the patients, aesthetic, and hygienic as there was no difficulty in maintaining oral hygiene.
