One-year follow-up study to evaluate the marginal bone resorption and attachment loss with customized post with stud attachment and prefabricated access post for mandibular overdenture

AIM: This study aims to analyze the marginal bone resorption and attachment loss of the overdenture attachment for the mandibular overdenture. SETTINGS AND DESIGN: Observational study done at MGV's KBH Dental College and Hospital, Nashik, Maharashtra, India. MATERIALS AND METHODS: A total of 30 subjects were selected of either sex between the age group of 50-70 years by designate of randomized parallel controlled sampling technique. The Cone beam computed tomography (CBCT) radiographic quantification determines the caliber of bone resorption and University of North Carolina (UNC) probe checked the depth of attachment loss of the abutment teeth that receive the cast coping (nonattachment control group), customized post and stud attachment, and prefabricated access post. STATISTICAL ANALYSIS USED: Oneway ANOVA test and post hoc Bonferroni multiple test. RESULTS: statistical analysis reveals the comparison of distinction between groups is significant at P < 0.05. The control group records least bone resorption and attachment loss than Group II and Group I. However, Group II records marginally higher bone resorption and attachment loss than Group III. CONCLUSION: The result of the study within the physiologic limit analyze that, cast coping records least bone resorption and attachment loss followed by Customized post with stud attachment and prefabricated access posts. The prefabricated access post records higher bone resorption and attachment loss.
