AimThe aim of this prospective clinical study is to assess the 4-year outcomes of implant-supported restorations performed using a computer-guided template-assisted flapless implant surgery approach in patients reconstructed with fibula or iliac crest free flaps.Materials and methodsTwelve jaws in 10 patients were reconstructed with osteomyocutaneous free flap after tumour resection or gunshot wound, after complete healing computer-assisted template-based flapless implant placement, based on prosthetic and aesthetic analysis, was performed using a customized protocol. Treatment success was evaluated using the following parameters: survival of implants/prostheses, prosthetic and biologic complications, marginal bone remodelling, soft tissue parameters and patient satisfaction.ResultsA total of 56 implants were placed; the implants ranged between 8 and 16 mm in length and were either 3.5, 4.3 or 5 mm wide. All the patients have reached the 4-year follow-up. Three implants were lost accounting for an overall implant survival rate of 94.6%. No prosthesis were lost. Some complications were recorded. Four years after loading the mean marginal bone loss was 1.43 ± 0.49 mm at the palatal/lingual site and 1.48 ± 0.46 mm at the vestibular site. All the patients showed healthy soft tissues with stable probing depth (4 .93 ± 0.75%) and successful bleeding on probing values (12 ± 5.8%); 90% of patients were satisfied of the treatment at the 4-year follow-up.ConclusionsComputer-guided template-assisted flapless implant surgery seems to be a viable option for patients undergoing reconstruction with free flaps after tumour resection or gunshot trauma, although many challenges remain. A high degree of patient satisfactorily was reported.
