Abstract

Purpose: The objective of this study is to compare incidence and type of complications associated with mandibular implant supported fixed complete arch prostheses based on implant distribution. Material and Methods: Patient Selection: The retrospective study included data collected from axiUm CE Version 6.05.01.2007 from year July 2007 to July 2018 for all patients treated with mandibular implant supported fixed complete arch prostheses (MISFCPs) at Loma Linda University School of Dentistry (LLUSD). One hundred and twenty seven patient’s charts were reviewed to document implant distribution and incidences of complications associated with each implant distribution groups on MISFCPs. Complications like screw loosening, prosthetic teeth fracture, prostheses fracture, pain etc. associated with MISFCPs were documented and then compared between implant distribution groups. Different variables like age, gender, opposing arch, cantilever occluding units and number of implants were studied to report the incidence of association of complications with the variables if any. Inclusion criteria: All MISFCPs (placed in LLUSD) supported by endosseous root form implants. Exclusion criteria: Patients with history of TMD prior to implant treatment and patients with transitional implants. Data were statistically analyzed using the Pearson Chi square test to determine correlations (α = 0.05). Results Complications associated with implant distribution were not statistically significant. The incidence of tooth delamination/fracture was higher followed by acrylic resin base fracture (Group II > Group I). Among gender, male patient had more complications than female patients (Group II). Patients with opposing arch Fixed Complete Dentures (FCDs) had more complications in comparison to patients with opposing removable prosthesis. Patients with cantilever /occluding units 2 reported more complications in comparison to patients with cantilever occluding units 3 for Group I. No significant incidence of pain was reported with implants anterior to the foramen (n=63) and posterior to the foramen (n=54) from implant distribution. Since the P value is more than the significance level (0.05) in relation to complications associated with implant distribution groups, the null hypothesis was accepted. Conclusions: Within the limitations of this study, although all the three implant distribution groups revealed clinically acceptable fixed complete arch prostheses, implant placed anterior to the foramen bilaterally revealed overall less complications.
