ABSTRACT
PURPOSE: To compare prevalence and type of complications associated with metal resin fixed complete dentures based on implant distribution.
MATERIALS AND METHODS: This retrospective study included data collected for a period of 12 years for patients treated with maxillary and mandibular implant-supported fixed complete dentures at the School of Dentistry. In total, 223 patient’s charts were reviewed which included 100 maxillary and 123 mandibular fixed complete dentures (FCDs). Implant distribution and prevalence of complications associated with each implant-supported FCD were documented. Teeth delamination, the most common complication associated with fixed complete dentures, was compared between 2 implant distribution groups in each arch. Covariates including age, sex, opposing arch, cantilever occluding units, and number of implants were evaluated to determine their association with tooth delamination. Data and hypotheses were statistically analyzed using descriptive statistics along with logistic regression model. All tests of hypotheses were considered statistically significant at an alpha level of 0.05.
RESULTS: In the maxillary arch, some effect of the prevalence of tooth delamination was seen for the group which had implants placed posterior to canine eminence but was not statistically significant. Denture tooth delamination had the highest prevalence among complications irrespective of implant distribution. Significant denture tooth delamination was seen for patients with opposing FCDs in comparison to patients with removable opposing arch prostheses.
CONCLUSIONS: Implant distribution is not a significant factor related metal resin FCDs. Opposing FCDs have a significantly higher association with DTDs. This article is protected by copyright. All rights reserved.
