Abstract
Graftless sinus lift is one of the techniques that provides enough room for implant
placement in the atrophic posterior maxilla. Schneiderian membrane is known to have an
osteogenic nature. To the extent that Osseo progenitors can circulate, differentiate, and
regenerate bone, the blood clot alone can be thought of as an intrinsic bone-forming graft
material.
Aim of the study: This study was conducted with the aim of evaluating the effectiveness of
using Fibrin glue versus Titanium platelet-rich fibrin (T-PRF) as the sole filling material in
lateral sinus augmentation and concurrent implant placement.
Materials and methods: There were three groups made up of thirty participants: Study Group
1 (S1), which received Fibrin glue as a filling material; Study group 2 (S2), which received TPRF
as a filling material; and Control group (C), which didn’t receive any material. In the three
groups, sinus floor augmentation via the lateral osteotomy approach and concurrent implant
installation were done. The patients were evaluated both clinically and radiographically
immediately postoperatively and six months later.
Results: Between the three groups under study, no significant difference in pain or edema was
revealed, either immediately following surgery or one week later. Regarding implant stability,
there was a statistically significant increase in the mean Implant Stability Quotient (ISQ) value
between Study group 1 (S1) and the Control group (C) also between Study group 2 (S2) and
the Control group (C) (p2<0.001, p3=0.015, respectively). However, no significant difference
was found in the mean ISQ value between Study group 1 (S1) and Study group 2 (S2) (p1 =
0.273) six months following the surgery. There was a significant increase in the vertical bone
height while comparing Study group 1 (S1) with Study group 2 (S2) at 6 months
postoperatively (p1 = 0.089); also, the bone height after six months was significantly higher in
Study group 1 (S1) than in the Control group (C) (p2 = 0.018); however, no significant
difference was revealed between Study group 2 (S2) and the Control group (C) regarding the
vertical bone height six months after surgery (p3 = 0.741). There was a significant increase in
bone density when comparing Study group 1 (S1) or Study group 2 (S2) with the negative
Control group (C) (p2 <0.001, p3 <0.001); however, no significant difference was found
between Study group 1 (S1) and Study group 2 (S2) in terms of bone density six months
following the surgery (p1=0.123).
Conclusion: Graftless sinus lifting is regarded as a dependable, safe, and low-cost procedure.
The use of Fibrin glue or T-PRF as a filling material significantly improved implant stability,
bone height gain, and bone density without causing any additional postoperative complications.
