Prospective Study on the Augmentation of the Maxillary Sinus With Calcium Sulfate: Histological Results

Abstract

The results of this study indicate that calcium sulfate appears to be an effective material for sinus augmentation, yielding vital bone suitable for implant integration. In addition, the technique used in the test group seemed to improve the quality and quantity of bone formation.

Various Ways to Enhance the Results of Maxillary Sinus Augmentation Procedures

“…Calcium sulfate hemihydrate has been proposed as a grafting material for sinus augmentation, and this resulted in good, new tissue formation within the sinuses when clinically and radiographically evaluated. The histomorphometiric analysis revealed bone density of 34.3% to 55.54% (De Leonardis and Pecora 2000). Similar results were achieved by other investigators (Pecora et al, 1998), and the study done at two years revealed new irregular trabecular design was seen radiographically and revealed normal, vital trabecular bone with woven and lamellar structure in all the histollogically examined sections (Guarnieri et al, 2006).…”

Sulfato de calcio: propiedades y aplicaciones clínicas

“…Estos resultados y otros revelan buena formación de tejido clínica y radiográficamente (27) . La técnica utilizada en el grupo de prueba produjo una reducción en la contracción del injerto durante la cicatrización, disminuyendo la tasa de reabsorción del material.…”

A Novel Injectable Poly(ε‐caprolactone)/Calcium Sulfate System for Bone Regeneration: Synthesis and Characterization

“…[5,[7][8][9][10][11][12]14,15,17,[24][25][26][27][28][29][30][31][32][33][34][35][36][37] In particular, hydroxyapatite (HA), structurally similar to the mineral phase of bone, has been the most widely employed as bioceramic for the hard tissue repair, [7,[10][11][12][16][17][18][19] however it is hard (not injectable), [18] Summary: A novel poly(e-caprolactone)/calcium sulfate system was prepared and characterized in order to enhance calcium sulfate (gypsum) performance as bone graft substitute overcoming its brittleness and fast resorption rate. A poly(e-caprolactone) (PCL) photo-crosslinkable derivative (PCL f ) was synthesized by reaction of a low molecular weight PCL diol with methacryloyl chloride and confirmed by FT-IR and 1 H NMR analyses.…”

“…[24][25][26][27][28][29][30][31][32][33][34][35][36] It has been utilized in periodontal disease, endodontic lesions, alveolar bone loss and maxillary sinus augmentation. [24][25][26][27][28][29][30][31][32][33][34][35][36] It is well tolerated by the tissues, [25,32,35] resorbable, [25,32,35] acts as a space maintainer that prevents soft tissue from invading the defect until bone can grow in [25,30,36] and proved very osteogenic in vivo. [25,30,35] Calcium sulfate is generally employed in the hemi-hydrate form (CaSO 4 Á ½ H 2 O or CHS) which is transformed, by reaction with water, in the hard di-hydrate one (CaSO 4 Á 2 H 2 O or gypsum).…”
