Comparative histomorphometric analysis of maxillary sinus augmentation with absorbable collagen membrane and osteoinductive replaceable bony window in rabbits.

Purpose: The aim of this animal study was to evaluate, through histomorphometric evaluation, bone regeneration in rabbit maxillary sinuses with absorbable collagen membranes and osteoinductive replaceable bony windows over bone grafts.

Materials And Methods: Bilateral sinus augmentation procedures were performed in 16 adult male rabbits. The rabbits were randomly assigned to 4 groups of 4 rabbits each.

Histomorphometric evaluation of mineralized cancellous allograft in the maxillary sinus augmentation: a 4 case report.

Purpose: The aim of this article is to report the histomorphometric analysis and clinical study of mineralized cancellous bone allografts in maxillary sinus augmentation procedures in 4 cases.

Materials And Methods: Sinus bone augmentation, using a piezoelectric device and mineralized cancellous allografts, was performed in 3 patients. After an average of about 8 months of healing, a trephine core sample was gained from the lateral windows area for histomorphometric analysis.

Fungal infection as a complication of sinus bone grafting and implants: a case report.

Sinus bone grafts have been used successfully to augment atrophic posterior maxilla for dental implant placement. Even though sinus bone grafting is generally considered to be a safe surgical procedure, postoperative maxillary sinus infections can occur and therefore need to be considered. Bacteria, as well as viruses and fungi, have been identified as causative agents.

Minor tooth movements using microimplant anchorage: case reports.

For the treatment of extruded or tipped molars, various conventional techniques have been used. But those methods may lead to undesirable movement of the anchorage units and lengthen treatment time because of limited tooth-borne anchorage potential. Introduction of microimplants as orthodontic anchorage has expanded treatment possibilities because of their advantages.
