The aim of this report is to describe the challenges of treatment planning and management of implant fixture fracture with tooth wear on patient with financial constraints. A 67-year-old retired male patient came to the dental clinic with a complaint of a mobile implant-supported fixed prosthesis, fractured implant fixture and attrited lower dentition. Treatment plan was planned around low cost with the biggest benefit of the patient. Multispecialty care is involved such as root canal treatment, implant removal, restoration of remaining dentition and replacement of missing teeth with removable prosthesis. The patient was reviewed after a month of completing full treatment resulted in a good treatment outcome. Lack of maintenance regimen leads to failure and mobility of the implant prosthesis. Proper maintenance protocol, post-insertion instructions, and good patient compliance are the key factors in determining longevity of the restoration.

Dental implants provide prosthetic options such as implant- retained crown, bridge, dentures, implant- supported fixed and removable dentures. Survival and success rates of implant prostheses are dependent on the proper execution of protocols and adequate maintenance by the patient. The correct protocol and maintenance regime that involves loading of the prosthesis after achieving primary stability with a six-month recall period is known to provide a better outcome for the implant (Gulati et al., 2014; Montero, 2021).
