The use of platelet-rich fibrin prepared with titanium tubes (T-PRF) in external maxillary sinus lift combined with simultaneous implant placement (case series)
Abstract
Background Conventional implantation in the posterior maxillary region is often difficult due to the lack of sufficient bone between the alveolar crest and the floor of the maxillary sinus. However, the lack of bone height can be overcome by grafting the floor of the maxillary sinus with a sinus lift procedure, which is performed using various types of bone grafts. Aim The aim of this study was to evaluate the bone gain, success and stability of implants associated with a single-stage lateral window external sinus lift using platelet- rich fibrin prepared with titanium tube (T-PRF) alone as a filler instead of bone grafts. Materials and methods The study sample consisted of 7 case series of maxillary sinus lift via the lateral window in 6 patients with unilateral or bilateral posterior maxillary loss, aged 30–60 years. 14 implants were placed in one stage simultaneously with sinus lift using platelet-rich fibrin prepared with titanium tubes (T-PRF). The residual bone height (RBH) between the alveolar bone crest and the sinus floor was 4–5 mm. All patients underwent CBCT imaging preoperatively, immediately postoperatively, and 6 months later to assess the amount of bone gain and density, Implant Stability Quotient (ISQ) was evaluated immediately and after 3 and 6 months. Results The mean of ISQ values immediately after implantation was 67.50, after 3 months was 72.14, and after 6 months was 76.14, with a statistically significant difference between the monitoring periods.

How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health. Reported size: 6 participants or records.
