Abstract
This study aimed to evaluate the effect of lingual implant inclination on stresses around two-implant-retained overdentures with resilient stud attachments. Materials and methods: Four acrylic models representing a mandibular edentulous ridge were constructed. For each model, two implants were placed at canine areas. Models were classified into four types according to the degree of lingual implant inclination: group I (GI, 0 degrees), group II (GII, 5 degrees), group III (GIII, 10 degrees), and group IV (GIV, 20 degrees). Overdentures were connected to the implants with Locator attachments. Regular light-retention inserts were used for all groups, and extended range inserts were also used for GIV (GIVext), making a fifth comparison group. Four strain gauges were bonded at the buccal, lingual, mesial, and distal surfaces of each implant to monitor the stresses during bilateral and unilateral load application. Results: At different sites of strain gauges: Buccal and lingual strain gauges recorded the highest microstrain values, and mesial and distal gauges recorded the lowest values (without significant difference in between) . And at 20o pink recorded the highest microstrain values, and 0o pink recorded the lowest values. Conclusion: During unilateral and bilateral loading at the majority of strain gauge positions, 20o pink recorded the highest strain, and 20o red recorded the smallest strain. This means as the strain increased as lingual implant inclination increase except when red insert was used.
