Despite the highly developed spinal implants and surgical techniques in stabilization, fusion failure is still most important problem today. Among factors that play a role success of fusion, are type graft material, contact area with tissue on widest possible surface, good blood supply ends bone will fuse surrounding muscle soft tissue, prevention movement tissues be fused placement appropriate...
Objective: To asses and compare the hearing outcome healing of Temporalis fascia graft in both groups by placing medial (underlay technique) or lateral to handle malleus (over- underlay technique). Method: This retrospective study conducted for a period January,2018 December 2019- Two years Specialized ENT Hospital (SENTH) SAHIC (Society assistance impaired Children), Dhaka. It includes 104 pat...
background and aims. plasma rich in growth factors (prgf) is a concentrated suspension of growth factors, which is used to promote periodontal tissue regeneration. the aim of this randomized, controlled, clinical trial was to evaluate of the treatment of grade ii mandibular molar furcation involvement using autogenous bone graft with and without prgf. materials and methods. in this double-blind...
Increasing numbers of patients are receiving reduced intensity conditioning regimen allogeneic hematopoietic stem cell transplantation. We hypothesized that the use of bone marrow graft might decrease the risk of graft-versus-host disease compared to peripheral blood after reduced intensity conditioning regimens without compromising graft-versus-leukemia effects. Patients who underwent reduced ...
Patients wearing complete dentures for a long time usually exhibit lack of bone and keratinized mucosa in the bearing area due to bone resorption. The patients suffering from this phenomenon usually have unstable and non-retentive complete denture, which result in constant trauma to the mucosa, pain, functional limitations and worsening of facial esthetics. An innovative technique has been desc...
BACKGROUND The primary objective of this study is to use histomorphometric techniques to evaluate the concept that the new bone formed in the maxillary sinus lift procedure emanates from the endosteum of the sinus floor. In addition, the effect of the residual crest vertical dimension on the graft outcome and assessment of osteoclast numbers as an indirect measure of a connection between the cr...
In the article “Acetabular roof reconstruction with pedicled iliac graft” published in International Orthopaedics [1], we presented a new method for reconstruction of the supero-lateral acetabular rim using a vascularised iliac graft based on the deep-circumflex artery and vein. Pedicled iliac graft is one of the most commonly used grafts, because it provides a strong piece of bone while the va...
BACKGROUND Despite increasing attention on fixation of a soft tissue anterior cruciate ligament graft in the tibia, there have been no studies on the use of a bone dowel as a joint line fixation device for promoting fixation properties, especially stiffness at the time of implantation. PURPOSE To determine whether compacting a bone dowel into the tibial tunnel improves fixation stiffness, yie...
OBJECTIVE To review short term results of uncemented cup implantation and the fate of bulk femoral head autografts in patients with acetabular bone deficiency due to dysplasia of the hip. We used bone scintigraphy to assess the viability of the grafts. METHODS We treated 19 hip joints of 17 patients with osteoarthritis due to developmental dysplasia of the hip with uncemented total hip arthro...
PURPOSE The objective of this study was to clinically evaluate the use of OSTEON as a sinus graft material and to measure the effect of healing at 4 and 6 months after surgery. MATERIALS AND METHODS After sinus graft using OSTEON in 17 patients, bone specimens were collected from lateral sinus using 2.0-mm trephine bur at the time of 4 or 6 months after surgery. Histology of the bone specimen...
