BACKGROUND: Suspension suture button fixation was frequently used to treat acromioclavicular joint (ACJ) dislocation. However, there were many studies reporting about complications and residual horizontal instability after fixation. Our study compared the stability of ACJ after fixation between coracoclavicular (CC) fixation alone and CC fixation combined with ACJ repair by using finite element analysis (FEA). MATERIALS AND METHODS: A finite element model was created by using CT images from the normal shoulder...

OBJECTIVE: Loss of teeth frequently results in compound horizontal and vertical alveolar bone defects. An appropriate bone structure is the key for implant placement and bony support of soft tissues. Advanced bone augmentation techniques are required for the reconstruction of these defects. This report will present a new bone block grafting technique with 12-month follow-up. METHOD: The seedling technique was used to augment the alveolar bone 3-dimensionally with autologous bone block and an osseointegrated implant in a 2-stage procedure...

This paper introduces a three-stage split-crest (TSSC) technique for horizontal ridge augmentation in the atrophic posterior mandible. The first stage consists of splitting the ridge. Following a 3- to 4-week healing interval, the second stage consists of expansion of the cortical plate (without elevating the periosteum) and placement of a bone replacement graft material. After 3 to 4 months of healing, the implants are placed. The advantages of this three-stage technique are increased vascularization to the surgical area, a decrease in procedure complications, and improved implant survival rates...

Alveolar ridge deficiency is considered a major limitation for successful implant placement, as well as for the long-term success rate, especially in the anterior maxillary region. Various approaches have been developed to increase bone volume. Among those approaches, inlay and onlay grafts, alveolar ridge distraction, and guided bone regeneration have been suggested. The use of titanium mesh is a reliable method for ridge augmentation. We describe a patient who presented with a localized, combined, horizontal and vertical ridge defect in the anterior maxilla...

The objective of this study was to present a novel procedure for cortical bone repositioning (CBR) that maintains a secure space under the periosteum by replacement of the lateral cortex via fixation, employing titanium screws. Seven systemically healthy patients presenting with horizontal alveolar bone defects in radiographs and CT images were enrolled for CBR technique for horizontal alveolar bone augmentation. A lateral cortical bone block was cut in the defects and freed from the original bony surface. A screw was inserted into the block, and the block was placed laterally to allow fixation...

This technique describes a novel approach for planning and augmenting a large bony defect using a titanium mesh (TiMe). A 3-dimensional (3D) surgical model was virtually created from a cone beam computed tomography (CBCT) and wax-pattern of the final prosthetic outcome. The required bone volume (horizontally and vertically) was digitally augmented and then 3D printed to create a bone model. The 3D model was then used to contour the TiMe in accordance with the digital augmentation. With the contoured / preformed TiMe on the 3D printed model a positioning jig was made to aid the placement of the TiMe as planned during surgery...

The reconstruction of deficient alveolar ridges using vertical and/or horizontal guided bone regeneration techniques allows for ideal implant placement, which is crucial for function and also for esthetically successful outcomes. Unlike in the past, when meeting a patient's functional demands was sufficient, many patients now have greater expectations from their implant restoration. Hence, it is no longer enough simply to restore the edentulous space with a functioning tooth or teeth. It has been suggested that patients now measure their final restoration using the contralateral natural tooth as the gold standard...

The rehabilitation of partially or totally edentulous patients with implant-supported prostheses has become routine, with excellent long-term outcome. A proper implant position is mandatory to achieve good functional and esthetic outcome and may require an adequate amount of alveolar bone and surrounding soft tissue. When this is lacking because of atrophy, sequelae of periodontal disease, traumas or congenital malformations, increased bone volume and/or keratinized mucosa can be obtained by guided bone regeneration, bone-grafting techniques and alveolar bone expansion...

A total of six patients treated from 2010 to 2014, having a knife-edge ridge (Cawood-Howell Class IV resorbed ridges) and requiring an implant-prosthetic rehabilitation, were selected. Tomographic measurement of the edentulous ridges was performed before grafting and after implant placement. At 6 months postgraft, a total of 41 implants had been inserted, 17 in the posterior region, 12 in the central region, and 12 in the anterior region. No surgical or healing complications were recorded, and the prostheses were loaded 6 to 9 months after implant placement...

Reconstruction of bone loss in the alveolar ridge has long been challenging. Autologous bone grafts are considered as the "golden standard," while little research has focused on how to repair pronounced alveolar bone defects after autologous bone graft failure. The aim of this study was to detail a method based on the titanium mesh technique coupled with particulate coral hydroxyapatite to solve the onlay graft failure. With bone deficiency in the No. 11 and No. 24-25 regions, we harvested 2 autologous bone blocks for reconstruction...
