Bone Formation in Maxillary Sinus Lift Using Autogenous Bone Graft at 2 and 6 Months

Abstract

The aim of this study is to compare the bone formation in maxillary sinus lift with an autogenous bone graft in histological evaluation at 2 or 6 months. A comparative study was designed where 10 patients with missing teeth bilaterally in the posterior zone of the maxilla were selected. Patients received a particulate autogenous bone graft under the same surgical conditions, selecting a site to collect a biopsy and histological study at two months and another at six months postoperatively. Histomorphometry was performed and were used Kolmogorov-Smirnov test, student's t-test and Spearman's correlation coefficient, considering a value of p<0.05. Differences were observed in inflammatory infiltrate and vascularization characteristics; however, the group analyzed at two months presented 38.12% ± 6.64 % of mineralized tissue, whereas the group studied at 6 months presented an average of 38.45 ± 9.27 %. There were no statistical differences between the groups. It is concluded that the bone formation may be similar in intrasinus particulate autogenous bone grafts in evaluations at two or six months; under these conditions, early installation of implants is viable.

Histologic and Histomorphometric Comparison between Sintered Nanohydroxyapatite and Anorganic Bovine Xenograft in Maxillary Sinus Grafting: A Split-Mouth Randomized Controlled Clinical Trial

“…Our data are in accordance with other human studies performed by using synthetic hydroxyapatites as sinus grafting material, reporting new bone formation at six months ranging from 32 to 38.5% [ 40 – 42 ]. These results are also comparable with the histomorphometric outcomes of sinus augmentation performed by using solely autogenous bone (new bone formation at six months ranging from 36.8 to 41%) [ 41 , 43 – 45 ].…”

Comparative analysis of two mixtures of biomaterials for maxillary sinus augmentation: clinical and histological study.

“…This type of stain is specific for showing the osteoid tissue (immature) and mature bone tissue. By histological evaluation of sections stained by MT, we found a significant increase in the percentage of matured bone tissue in group A more than group B.Even though large variety of grafting materials have been tested for maxillary sinus floor augmentation in both clinical and experimental studies [27][28][29][30][31][32] , this current study was the first that compare Hyaluronic acid versus Simvastatin as a grafting material for maxillary sinus floor augmentation. So, we cannot link our finding with other studies.…”

Residual Bone Height and New Bone Formation after Maxillary Sinus Augmentation Procedure Using Biomaterials: A Network Meta-Analysis of Clinical Trials

“…In total, 266 records did not meet the inclusion criteria based on titles and abstract were excluded. Upon full text assessment by two authors, 84 studies were selected for data extraction for qualitative analysis [ 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 ...…”
