Abstract

Objective: The aim of this study was to investigate the prevalence of fractures in Acrylic Removable Dentures in Sulaimani City.

Patients and methods: A questioner was used to collect the data from two dental laboratories. 264 fracture cases were collected.  The variables evaluated were; the fracture area, the possible cause of fracture, fracture frequency, place of denture construction, the age of the denture, and the type of Removable Denture, Partial or Complete Denture.

Results: The data result showed; The ratio of fracture incidence in complete denture to partial denture fracture was nearly 4:1, the ratio of upper to lower denture was 2:1, the most common fractures was midline fracture 112 (42.424%), followed by the De-Bonding of the artificial teeth 62 (23.484%). Dropping was the main possible cause of fracture 66 (25%), followed by poor occlusion 38 (14. 393%). 128 (48.484%) of the denture fractures was first time fracture, 136 (51.515%) of the dentures had repeated fracture. 112 (42.424%) of the fractured dentures were constructed by a technician like people (Dan Saz), 76 (28.787%) were constructed in dental hospital. 58 (21.969%) of the fractured dentures were constructed 1 years ago or less, 146 (55.303%) of the fractured dentures were more than 3 years old.      

Conclusion: Midline fracture had the highest rate among all the other types of fractures; fracture of upper denture was more than lower dentures. Dropping followed by the De-bonding of the artificial teeth was the most possible cause of fracture. Fracture rate increased among the dentures which were first constructed by a technician like people (Dan Saz).  Fracture frequency increased as the denture age increased, also increased among dentures with repeated fracture.
