Complication rate with prosthodontic reconstructions on ITI and IMZ dental implants

Abstract

Deproteinized cancellous bovine bone (Bio-Oss) was placed as a grafting material for sinus floor elevation in the right posterior maxilla. After 6 months of healing, 3 cylindrical titanium-plasma coated implants were inserted. Six months later at the abutment connection, it was realized that 1 of the implants could not be reconstructed due to unfavorable positioning. This implant was removed along with a small portion of the surrounding peri-implant tissues. The specimen was processed according to standard techniques for hard tissue histology. In both the grafted area and the previously existing area of the sinus floor the bone was primarily of lamellar structure. Intimate contact between newly formed bone and the particles of the graft was present. No overt signs of resorption of the graft particles were visible. Histomorphometric analysis revealed 63% of implant-bone contact in the zone of pre-existing bone, and 73% in the grafted zone. The area density of bone amounted to 27% in the non-grafted as compared to 28% in the grafted area. In conclusion, this case report documented that deproteinized bovine bone, when used as a grafting material for augmentation of the sinus floor, may lead to proper osseointegration of a dental implant.

Induction of multinucleated giant cells in response to small sized bovine bone substitute (Bio-Oss TM ) results in an enhanced early implantation bed vascularization

“…Various in vivo studies have shown Bio-Oss TM to be highly biocompatible, stable and to have a long-term efficacy. [ 6 7 8 9 ] It has also been shown to be present in the augmentation site years after implantation,[ 7 ] and so has the capacity to form a stable foundation for subsequent implantations. This has made it suitable for use in sinus lift, mandibular and maxillary bone augmentations, guided bone regeneration, and a host of other surgical applications.…”

Translational Research for Injectable Tissue-Engineered Bone Regeneration Using Mesenchymal Stem Cells and Platelet-Rich Plasma: From Basic Research to Clinical Case Study

“…Implants placed in injectable tissue-engineered bone regeneration areas We have attempted to regenerate bone in a significant osseous defect with minimal invasiveness, good plasticwere compared to implants placed in nonregenerated, PRP-regenerated, PCBM-regenerated, and native bone. ity, and nonimmunoreactivity, which could provide a clinical alternative to autogenous bone grafts (27)(28)(29)(30)(31).…”

Bone Substitutes

“…Anorganic bovine bone (ABB): ABB is a biocompatible and osteoconductive anorganic bovine bone (ABB), that provides an ideal scaffold for new bone formation (Hammerle et al, 1998, Piatelli et al, 1999. It has been extensively used in maxillary sinus floor augmentation (Valentini et al, 2003, Wallace et al, 2005 with high clinical success rates (Carmagnola et al, 2003). Comparative studies by Hallman et al and Valentini and Abensur observed higher survival rates for implants placed in sinuses grafted with 100% ABB compared with sinuses grafted with 100% autograft (Hallman., 2002, Valentini., 2003.…”

Also Froum reports higher implant survival rate in sinuses grafted with ABB alone than those grafted with a composite of ABB+DFDBA (Froum et al, 2006).…”
