Treatment of severely resorbed partially or completely edentulous maxillae can include the utilization of the zygomatic process for immediate implant fixation and stabilization with immediate function. This approach may alleviate the need for significant grafting to enable implant placement in the posterior maxilla and allow implants to be placed into denser, more stable bone. Zygomatic implants, which have been used clinically for the past 20 years in the treatment of the severely resorbed maxilla, allow implant placement to support fixed prosthetics...

Atrophy of the alveolar ridge requires bone grafting at the implant site for rehabilitation of the masticatory function with dental implants. Despite the advances in the development of bone substitutes, autogenous bone graft remains the "criterion standard" because of its osteogenic, osteoinductive, osteoconductive potential, and non-immunogenic properties. However, harvesting of autogenous bone is not exempt from donor site morbidity. In this context, the use of autogenous bone derived from the proximal ulna might be a viable resource to obtain corticocancellous bone graft, as the harvesting from this donor site is associated with low morbidity...

Missing or reduced buccal bone plates and a reduced vertical dimension still represent challenges in bone grafting and require a three-dimensional (3D) reconstruction. The protocol presented in this short technical note describes the clinical application of a patient-specific, titanium lattice structure for customized bone regeneration (CBR). A 3D projection of the bony defect is generated, and an individualized titanium lattice structure designed using computer-aided design/computer-aided manufacturing (CAD/CAM) procedures and rapid prototyping...

PURPOSE: The most effective rehabilitation method for patients with edentulous posterior maxillas with an intermediate (4 to 8 mm) residual bone height (RBH) below the maxillary sinus is unclear. Evidence derived from conventional meta-analysis is limited because of the lack of head-to-head studies. This network meta-analysis (NMA) was performed to identify the most effective method to treat patients with intermediate posterior RBH. MATERIALS AND METHODS: An NMA of randomized controlled clinical trials (RCTs) was conducted to assess various rehabilitation methods using implant-supported prostheses for patients with intermediate posterior maxillary RBH (4 to 8 mm)...

Alveolar bone loss is a common problem that affects dental implant placement. A barrier between the bone substitute and gingiva that can prevent fibro-tissue ingrowth, bacterial infection and induce bone formation is a key factor in improving the success of alveolar ridge reconstruction. This study aims to develop a bioactive collagen barrier material for guided bone regeneration, that is coupled with anti-bacterial and anti-inflammatory properties. We have evaluated two silver coating methods and found controllable and precise coating achieved by sonication compared with sputtering...

Severe maxillary deficiency is often seen in cleft lip and palate patients due to multiple factors such as congenital defect, traumatic effect of surgeries and constriction of scar tissue, which causes moderate to severe crowding and anterior and posterior crossbite. Orthodontic treatment is usually difficult and time consuming. Upper arch expansion and maxillary protraction are often carried out to release transverse and sagittal intermaxillary discrepancy. Orthodontic treatment for cleft patients is different from that of non-cleft patients...
