PURPOSE To evaluate the long-term outcome of a single-step ridge expansion osteotome procedure and implant placement combined with guided bone regeneration in patients presenting narrow maxillary alveolar ridges. MATERIALS AND METHODS During the period 1999 to 2010, 41 patients aged 19 to 77 years (18 males; 23 females) suffering from partial or full edentulism associated with horizontal reso...

BACKGROUND Optimal tunnel placement is critical in anterior cruciate ligament reconstructive surgery, yet the method used to drill the tunnels may compromise their placement. HYPOTHESIS An independent drilling method versus a conventional transtibial drilling method will place tunnels in different locations and produce reconstructions with different kinematics. STUDY DESIGN Controlled labor...

OBJECTIVES To evaluate whether 7-mm-long implants could be an alternative to longer implants placed in vertically augmented posterior mandibles. MATERIALS AND METHODS Sixty patients with posterior mandibular edentulism with 7-8 mm bone height above the mandibular canal were randomized to either vertical augmentation with anorganic bovine bone blocks and delayed 5-month placement of ≥10 mm imp...

Scientific literature describes autogenous bone as the gold standard among graft materials for alveolar reconstructive procedures. Alveolar ridge augmentation has been clinically achieved with different forms of autogenous bone, including autogenous cortical bone particulate (ACBP). However, few histologic studies demonstrating the biologic potential and healing dynamics following the use of AC...

There is little evidence examining the relationship between anatomical landmarks, radiological placement of the tunnels and long-term clinical outcomes following anterior cruciate ligament (ACL) reconstruction. The aim of this study was to investigate the reproducibility of intra-operative landmarks for placement of the tunnels in single-bundle reconstruction of the ACL using four-strand hamstr...

BACKGROUND The purpose of this study was to evaluate the long-term swallowing function in patients with vertical hemipharyngolaryngectomy (VHPL) for hypopharyngeal cancer. METHODS A retrospective review of 30 patients followed for more than 2 years with VHPL between 1998 and 2011 was performed. RESULTS Five patients (16.7%) experienced gastrostomy tube placement, 4 patients (13%) had pharyn...

The loss of teeth followed by bone resorption often lead to defects in the alveolar ridge, making installation of dental implants difficult. Correction of such bone defects, especially lack of height of the ridge, is a difficult problem for all dental surgeons. This report describes the outcome of treatment after alveolar ridge augmentation in the atrophic posterior maxillary region via segment...

In a non-guillotinable rectangular strip packing problem (RF-SPP), the best orthogonal placement of given rectangular pieces on a strip of stock sheet having fixed width and infinite height are searched. The aim is to minimize the height of the strip while including all the pieces in appropriate orientations. In this study, a novel bidirectional best-fit heuristic (BBF) is introduced for solvin...

OBJECTIVES The purpose of this study was to evaluate the sinus bone graft resorption over 3 years after two-stage implant placement. MATERIALS AND METHODS The subjects for this study included 30 patients whose maxillary posterior ridges were too atrophic for implants. Bone-added osteotome sinus floor elevation was used in 15 maxillary sinuses, while the bone graft by lateral approach techniqu...

fabrication or implant placement in a prosthetically ideal position.1 Alveolar ridge defects that result from trauma, tooth extraction, or periodontal diseases often require periodontal-surgical correction before prosthetic treatment. Especially, in the esthetically important anterior arch segments, any surgical endeavor will require implants (osseous buildup) or fixed bridge constructions (sof...
