First used in 1892 by Dreesmann

Self reinforced

Biocompatible

Cementable material

Biodegradable (totally replaced by bone)

Promotes bone formation

Compatible with other augmentation materials, medicaments, Growth factors, antibiotics, etc

Haemostatic

Bacteriostatic

Complete wound closure during surgery is not required (epithelial can grow over it)

Abundant and not expensive material

Throughout the years it has been found to be non-toxic, non-irritating, highly biocompatible and osteoconductive, inexpensive, available and easy to use (Coetzee, 1980; Gitelis et al., 2001; Kelly et al., 2001).

Lack of significant host response post implantation is an important characteristic of calcium sulfate (Alderman, 1969; Bahn, 1966; Bell, 1964; Peltier, 1959; Peltier, 1961; Peltier and Orn, 1958)

Histologic studies of the use of calcium sulfate in animals, mainly in dogs and in rabbits, have shown that the trabecular bone, filling surgically created bone defects, was qualitatively similar to that seen with autogenous bone graft.

The resorption profile of calcium sulfate matches the rate at which the host environment can lay down bone around the implant (Bahn, 1966; Tay et al., 1999). (Silveira et al., 2008)

In humans, calcium sulfate has been shown to be a completely resorbable promoting osteogenic activity, and stimulating bone growth in contact with bone or periosteum (Coetzee (1980), (case report with SurgiPlaster, Scarano et al., 2007), Slater et al (2008))

Ricci and co-authors (2000) reported formation of a mineralized, HA - like latticework as the calcium sulfate dissolved.

Sulfate particles bind firmly to adjacent bone, and guide new bone formation as the material resorbs (Coetzee, 1980). For every molecule of calcium sulfate resorbed, a molecule of hydroxyapatite may be deposited in its place.

Calcium sulfate is radiopaque, thus allowing for the monitoring of their resorption following implantation by X-ray technique in the clinical setting.

One of the major concerns regarding calcium sulfate is

related to its fast resorption.

Ricci (2001) assumed that it is very likely that improper use

of calcium sulfate or of inconsistent material have

resulted in failed attempts to use this material as bone filler

Calcium sulfate hemihydrate is not suitable for the

treatment of large cavities due to several reasons:

Its expansion properties during

setting, which may cause pain to the

patients

Its low mechanical

integrity, and setting under

blood and saliva.‏

its high dissolution rate and fast

resorption by the human bone

Calcium sulfate dihydrate has acceptable expansion

properties. However, its use in repairing bone defects is

limited since it has no cementitious properties.

• In the periodontal literature there are case reports of intra bony defects treated with calcium sulfate or composite grafts.

• Paolantonio et al. (2008) reported that there were no significant differences between collagen membrane and calcium sulfate treatments.

• Both treatments had significantly greater PD reduction and CAL(clinical attachment level ) and DBL(defect bone level ) gain compared to the OFD

• Scarano et al. (2007) evaluated the tissues in a peri-implant site regenerated with calcium sulfate.

• In light microscopy histology , trabecular bone was present with no remnants of calcium sulfate.

• Transmission electron microscopy showed, in the areas of the interface with the implant surface, mature bone with many osteocytes.

• On the metal surface an amorphous layer of osteoid was found.
