PERIODONTICS

Periodontics

A review of present literature supports clinical applications of prefabricated implants made of Bioglass ceramics, as has been used in calvarial and midface bone reconstructions as well as for the repair of orbital floor fractures. Also, present experience with Bioglass in particulate form, preferably mixed with small amount of autogenous bone, support the convenience of this biomaterial over alternate forms of synthetic graft materials. 
 A 5-year evaluation on Bioactive glass cones was conducted to examine the effectiveness of Bioactive cones as space fillers after removal of tooth roots to delay the resorption of alveolar ridges (Stanley et al). High rate (85.7%) of cone retention after 5 years. Placement of Bioactive glass into fresh sockets promoted alveolar ridge preservation and is said to be a material of choice for endosseous ridge maintenance implants to prevent alveolar ridge resorption.
Retrospective review was conducted to evaluate Particulate bioactive glass as a grafting material in the treatment of periodontal intrabony defects. Results demonstrated the efficiency of Bioactive glass as an adjunct to conventional surgery in the treatment of intrabony defects.
Histological observations on biopsies harvested following sinus floor elevation using a bioactive glass material of narrow size range were made to evaluate the bone augmenting capacity of bioactive glass particles in human sinus floor elevations. Results demonstrated that a 1:1 mixture of autogenous bone/Bioactive glass particles seemed a promising alternative to autogenous bone only, when low amounts of bone tissue are available for sinus augmentation.
