Crestal Approach to Sinus Floor Elevation for Atrophic Maxilla Using Platelet-Rich Fibrin as the Only Grafting Material

Abstract

This prospective study showed that platelet-rich fibrin promoted endosinus bone gain when used as the grafting material in the crestal approach to sinus floor elevation.

Implant Placement after Sinus Augmentation with Hydroxyapatite Bone Graft and Platelet Rich Fibrin Membrane Closure: A Report of 2 Cases

“…Studies have shown that PRF has greater osteogenic ability, involves a simple preparation process, is devoid of extrinsic biological agents, and has sustained release of growth factors [5]. Previous studies have revealed the potential of PRF to promote endosinus bone regeneration [3,4] and to reduce healing time after sinus floor elevation [5]. In our case bone height and density were significantly improved with the use of hydroxyapatite and PRF membrane.…”

“…The sinus augmentation procedure provides a way to increase the amount of available bone and the placement of longer implants [1].The advantage of using Platelet rich fibrin (PRF) is that it has increased osteogenic ability, a simple preparation process, absence of extrinsic biological agents, and sustained release of growth factors [2].There are many studies conducted to reveal the potential of PRF to promote endosinusbone regeneration [3], [4]and to reduce healing time after sinus floor elevation [5].…”

Improvements in the Crestal Osteotome Approach Have Decreased the Need for the Lateral Window Approach to Augment the Maxilla

“…Six references (16,17,(19)(20)(21)(22) reported bone gains ranging from 1.8 to 5.7 mm using a crestal approach with no graft placement. Deviations in reporting and data collection prevent a meaningful statistical analysis other than noting the consistency of results.…”

“…Maintenance of the space created after membrane elevation may be important for bone formation to occur (15)(16)(17)(18)(19)(20). The decision to use an osteotome method via the crestal approach allows elevation of the membrane with or without graft placement, which can result in adequate bone function for long-term implant success (7).…”

“…The bone gain from using the osteotome technique from the crestal approach ranges from 4 to 6 mm, with or without grafting (16,17,(19)(20)(21)(22)(23)(24)(25)(26). Different grafting materials did not seem to affect implant success rates (7,24).…”
