Treatment Effect on Social Engagement with Mandibular Implant Overdenture Therapy

In order to distinguish essays and pre-prints from academic theses, we have a separate category. These are often much longer text based documents than a paper.
The purpose of this research study was to investigate if patients with conventional mandibular dentures became more socially engaged following mandibular two-implant overdenture therapy, to determine if gender differences exist regarding treatment effect on social engagement with mandibular two-implant overdenture therapy, and to investigate patient satisfaction post-treatment. Edentulous patients had conventional maxillary and mandibular complete dentures fabricated at the UIC COD. After a minimum of four months of function, the patients underwent two-stage mandibular implant overdenture therapy. Two interforaminal implants were placed, and after a minimum of three months healing time, the two osseointegrated mandibular implants were uncovered and healing abutments were inserted. A minimum of two weeks later, the mandibular denture was converted chair-side into a two implant-retained mandibular overdenture with resilient attachments. Information on demographics was obtained and patients completed both pre- and post-treatment questionnaires on social engagement after functioning with each prosthesis for a minimum for four months. In addition, post-treatment semantic differential scales and modified version of Oral Health Impact Profile-14 were completed. Twenty-seven patients, 14 men and 13 women, with a mean age of 62 years (SD±12), participated in the study. Statistical software (SPSS v.20, Armonk, NY, USA) was used for descriptive and statistical analyses. Wilcoxon Signed Ranks Tests resulted in significant differences (p<0.05) for the overall sample for “went on trips” (p=0.04); “visited” (p=0.03); and “engaged in leisure phone conversations” (p=0.02). Significant differences were noted for women on “did housework” (p=0.046); “smiled fully in social situations” (p=0.02); and “laughed fully in social situations” (p=0.02). For men, a significant difference was found for “went on trips” (p=0.03). Significant differences were found for participants <60 years of age for “smiled fully in social situations” (p=0.03) and “laughed fully in social situations” (p=0.02). Significant differences were found for participants >60 years of age for “engaged in leisure phone conversations with family” (p=0.05), “went to restaurants” (p=0.02) and “engaged in leisure phone conversations” (p=0.05). The overall median post-treatment semantic scale was nine, signifying a high level of post-treatment satisfaction and the overall median post treatment OHIP-14 was zero suggesting there was no interference by oral health with quality of life. The results are consistent with a small treatment effect on social engagement due to implant-supported mandibular overdenture treatment. There may be differences related to gender and age. Patients had a high level of satisfaction with treatment based on semantic differential scales and modified OHIP-14. Continuation of the current research study to obtain a larger sample size is recommended to further evaluate the treatment effect on social engagement with mandibular implant overdenture therapy.
