Introduction: This cross-sectional study was aimed to assess the available restorative space inside a complete denture for two-implant-supported mandibular overdenture at the lateral incisor tooth position, which aids in identifying the corresponding attachment system for the required restorative space for treating patients with implant-supported mandibular overdenture. Materials and Methods: Intaglio surfaces of fifty lower dentures duplicated with lab putty and putty cast were made. Polished surface and occlusal surface were duplicated with lab putty to obtain a putty index of the denture. The space from the crest of the ridge to the lingual surface of the denture at the right and left mandibular implant positions in the putty index was measured using periodontal probe. To measure the soft-tissue thickness, direct bone sounding was done at the right and left mandibular lateral implant positions. Results: The outcome variables were analyzed using Student's t-test. The overall average restorative space was found to be 7.64 mm with soft-tissue thickness added 9.64 mm. Hence, a ball or locator attachment systems are suitable for left and right lateral implant position was applicable. Conclusion: The ultimate choice of attachment type should be based on restorative space for two-implant mandibular overdenture. The clinical performance of the attachments regarding the functional loads on the implant and surrounding tissues, patient's satisfaction with treatment, technical problems, maintenance service, and attachment cost.
