Osteotome sinus floor elevation without grafting material: a 1‐year prospective pilot study with ITI implants

Abstract

Elevation of the sinus membrane alone without addition of bone grafting material can lead to bone formation beyond the original limits of the sinus floor. Despite a limited RBH at implant placement, a healing period of 3 months was sufficient to resist a torque of 35 N cm and to lead to a predictable implant function at the 1-year control.

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

“…2 In the crestal approach to graft-free sinus floor elevation, simultaneous implantation is needed, and the tips of the implants maintain the membrane at an adequate height by functioning essentially as "tent pegs." [3][4][5] In such a closed cavity below a lifted sinus membrane, the osteogenic potential of the bone and sinus membrane is highly protected. This method is considered less invasive and more affordable.…”

Maxillary Sinus Floor Elevation Techniques with Recent Advances: A Literature Review

“…This technique has been used as an alternative to conventional procedures [50][51][52][53][54][55][56][57][58][59][60][61][62][63]. MIAMBE balloon-harboring device (MiambeLTD, Netanya, Israel) consists of a stainless steel tube, three mm in diameter, that connects on its proximal end to the dedicated inflation syringe, and its distal portion has an embedded single use silicone balloon.…”

“…To elevate the sinus floor indirectly and provide a buffering effect to sinus floor, bone graft material is added using an amalgam carrier. (Fig.6D)The sinus floor is elevated by repeated bone grafting and osteotome insertion followed by placement of implants (Fig.6E) [62]. In another study, Ostetomes can be used for SFE without bone grafting if residual bone height (RBH) is 5.4 mm and this could lead to a mean endo-sinus bone gain of 1.2-2.5 mm [63].…”

New Bone Formation in the Maxillary Sinus With/Without Bone Graft

“…[15][16][17] However some studies reported new bone formation in animal and human's sinus with membrane elevation alone, resorbable gelatin sponge alone, venous blood alone and autologous fibrin gel with concentrated growth factors alone as alternatives to bone materials. [18][19][20][21][22][23][24][25] According to these studies, bone substitutes may not be a prerequisite for sinus augmentation. The function of elevated sinus membrane is controversial, but some studies reported that sinus membrane acted as periosteum and showed osteoinductive potetnial.…”
