Implant Survival in Renal-Transplanted Patients: A Prospective Long-Term Study

Area of Science:

• Oral and Maxillofacial Surgery
• Nephrology
• Periodontology

Background:

• Kidney transplantation recipients often face challenges with oral health.
• Assessing the viability of dental implant rehabilitation in this patient group is crucial.

Purpose of the Study:

• To evaluate the feasibility and long-term success of implant-supported prostheses in kidney-transplanted patients.
• To analyze histomorphometric and radiological bone parameters, implant stability, and survival rates.

Main Methods:

• Included kidney transplant patients with partial edentulism undergoing periodontal supportive care.
• Assessed bone quality via histomorphometry and radiography.
• Monitored implant stability using resonance frequency analysis and insertion torque.
• Followed a conventional loading protocol for fixed cemented prostheses.

Main Results:

• 17 implants were placed in 11 patients; 14/15 implants maintained function at 5-year follow-up (93.3% survival rate).
• Mean insertion torque value (ITV) was 39.3 Ncm; mean primary and secondary stability quotients were 71.7 and 73.0, respectively.
• Two implants developed peri-implantitis; bone analysis showed favorable characteristics for osseointegration.

Conclusions:

• Implant-supported rehabilitation is a viable option for kidney-transplant recipients.
• Consistent periodontal maintenance is key to achieving long-term implant survival in this population.
