RESUMO
Literature has proved that implant-retained overdenture is one of the best prosthetic options in the rehabilitation of complete edentulism. Tissue-supported implant-retained overdentures have been an appropriate treatment modality for atrophic mandibular ridges. In this case report, the patient presented with Class I maxillomandibular relationship and Class II Prosthodontic Diagnostic Index. The patient was concerned about esthetics as well as the retention of the lower denture. Taking into consideration the above concerns, an implant-retained mandibular overdenture was the chosen treatment modality. There are numerous attachment systems that have been used to improve the retention, stability, and support of implant-retained overdenture. Every attachment system has its own set of advantages. The OT Equator is a new line of low-profile attachment which is a radically modified OT-CAP Normo. The rationale for using this attachment is that it is considered the smallest attachment system available with the least overall dimension. It is a resilient and self-aligning attachment system which can be used in limited inter-arch space situation. OT equator derives its name from the OT Dental Laboratory (Bologna, Italy) used as a brand name. Considering these advantages, this was the chosen attachment and proved beneficial in terms of both patient satisfaction and the overall success of the treatment.
