Maxillary Sinus Augmentation Using a Titanium Mesh: A Randomized Clinical Trial

Abstract

BACKGROUND:Various attempts have been implemented using different materials and techniques to augment the maxillary sinus floor for prospect dental implant positioning.AIM:This contemplate was conducted to assess the osteogenic capability of the maxillary sinus in a two-step sinus membrane elevation using titanium mesh to keep the formed space to place dental implants in atrophic ridges.MATERIALS AND METHODS:Titanium micromesh was customized and positioned into the sinus on one side to preserve the elevated membrane in position. On the other side xenograft was applied. Instant and 6-months postoperative cone beam computed tomography (CBCT) was done to assess the gained bone height and density. Bone core biopsies were obtained during implant placement for histological and histomorphometric evaluation.RESULTS:The average bone height values increased in both groups. Meanwhile the average bone density value was higher at the graft group than the titanium mesh group. Histological and histomorphometric evaluation presented the average bone volume of the newly formed bone in the graft group which is superior to that of the titanium mesh group.CONCLUSION:The use of the titanium micromesh as a space-maintaining device after Schneiderian membrane elevation is a trustworthy technique to elevate the floor of the sinus without grafting.

Evaluation of bone formation following the osteotome sinus floor elevation technique without grafting using cone beam computed tomography: a preliminary study

“…Grafting the sites is thought to improve the primary stability by providing more bone onto which the implant can anchor [13, 37]. Moreover, the application of grafting material is thought to create and maintain the space for new bone formation.…”

The Role of Titanium Mesh in Limiting Dimensional Changes of Maxillary Sinus Graft: Randomized Clinical Trial

“…The benefit of this mixture was advocated by the authors who reported better new bone formation and faster healing 29,30 , however this subject is still controversial as a recent meta-analysis showed no evidence on the necessity of adding PRF to the grafting material. 31 In a case series, Atef et al 32 used a titanium mesh as space maintainer in a lateral graftless sinus lift and found promising results so Bahaa-eldin et al 33 performed a pilot study where they were able to place an implant in the newly formed bone under the titanium mesh but they reported that the density of this bone was far less than that of the bovine xenograft.…”
