Applications of maxillary tuberosity block autograft

Abstract

Objective: Autogenous bone grafts are considered the gold standard due to their compatibility and osteogenic potential to induce new bone formation through osteogenesis, osteoinduction, and osteoconduction. The aim of this paper was to describe clinical applications of the maxillary tuberosity block autograft in small and moderate localized defects of the alveolar process around implants and teeth.Clinical Considerations: Maxillary tuberosity is often used as a particulate graft for augmentation of deficient alveolar ridge or maxillary sinus prior to or simultaneously with implant insertion, but not as a bone block graft. The maxillary tuberosity block autograft may also provide a valuable bone source for challenging situations such as immediate implant placement into types II and III extraction sockets, treatment of horizontal and vertical bone defects with simultaneous implantation, reconstruction of circumferential defects around implants, and preservation of alveolar ridge. Conclusions:The advantages of the maxillary tuberosity include intraoral corticocancellous autogenous graft with fewer intraoperative difficulties, no need for donor site restoration, less morbidity, and an excellent correction of localized alveolar ridge defects.Clinical Significance: Within the limitations of the presented case reports, the use of maxillary tuberosity block autograft has shown to be successful in alveolar ridges augmentation that lack both width and height.

One-Stage Approach to Rehabilitate a Hopeless Tooth in the Maxilla by Means of Immediate Dentoalveolar Restoration: Surgical and Prosthetic Considerations

“…However, as shown in the present case, the missed buccal bone had not limited the implant placement, and the buccal bone reconstruction was performed immediately [2,28]. The reconstruction of the buccal bone wall using the tuberosity bone is limited to small bone defects and patients with sufficient mouth opening [29,30]. Besides, the use of an implant with surface treatment to accelerate the osseointegration process instead of using a machined titanium implant is also recommended [31,32].…”

Immediate ridge reconstruction with a composite tuberosity graft after removal of failing implants

“…The application of tuberosity bone blocks has previously resulted in favorable outcomes and minimal donor site morbidity. [3][4][5][6] Immediate dentoalveolar restorations, a technique for the treatment of compromised sockets, popularized the usage of tuberosity grafts. 7,8 The cortical portion of the graft provides structural support, while the cancellous part has osteogenic, osteoinductive, and osteoconductive properties.…”

Osteogenically committed hUCMSCs-derived exosomes promote the recovery of critical-sized bone defects with enhanced osteogenic properties

“… 1,2 Autografts are considered as the “gold standard” to repair bone defects because they bear excellent biocompatibility, osteoconductivity, osteoinductivity, and osteogenesis-related cells. 3,4 However, several shortcomings of autografts, such as the secondary operation area and limited bone volume restrict the clinical application. As alternatives, allografts, 5 xenografts, 6 and artificial bone grafts 7 that bear similar structures and compositions to bone tissue, have been widely used in the clinic.…”
