Abstract:
OBJECTIVETo evaluate the bracket bond failure and its causes between adult and adolescent patients during fixed orthodontic therapy.
METHODSBracket bond failure data of 30 adults and 30 adolescents, receiving fixed orthodontic therapy, have been collected within the first 12 visits, respectively. The compliance has been analyzed with survival analyse between the two groups.
RESULTThe general bracket bond failure rate in the adult group is lower than that of the adolescent group and the difference is significant (p < 0.05). In the adolescent group, the failure rate for mandibular anterior teeth is highest and different from that of the adult group (p < 0.05). The failure rate resulted from biting hard food is ranked No. 1.
CONCLUSIONSThe compliance of the adults receiving fixed orthodontic therapy is better than that of the adolescents. The investigation of bracket bond failure causes is beneficial in helping orthodontists improve orthodontic practice and raise clinical efficiency. The survival analysis is effective in evaluating the bond failure.
