This study evaluated the influence of smooth and brushite-coated implant surfaces in dogs. The first through fourth mandibular premolars were extracted from eight young adult dogs. Twelve weeks after extraction. implantation was performed at the extraction sites. In total, 40 implant fixtures were implanted in the dog mandibles. Twenty machined implants served as controls and twenty brushite-coated surfaces served as tests. Dogs were sacrificed 2 and 4 weeks after implantation. The hemi-mandibles were obtained and processed histologically to obtain non-decalcified sections. Longitudinal sections of each implant were made and analyzed using light microscopy. The overall implant success rate was 83.3%. Histomorphometrically. the experimental group had a better percentage of bone-implant contact than the control group (p<0.05) and there was a significant difference between the 2- and 4-week groups after implantation (p<0.05) Our results suggest that the implant surface morphology influences the increase in peri-implant osteogenesis in the early period of peri-implant healing.

턱관절 질환 치료 시 Sodium Hyaluronate의 효과

문철웅,김수관,Moon, Chul-Woong,Kim, Su-Gwan 대한악안면성형재건외과학회 2006 Maxillofacial Plastic Reconstructive Surgery Vol.28 No.3

The term temporomandibular disorders is used to describe a group of conditions that involve the temporomandibular joint, masticatory muscles, and associated structures. Many modalities have been proposed for treating temporomandibular disorders, including medication, physical therapy, occlusal stabilization splints with or without manual repositioning, surgery, and arthrocentesis. Temporomandibular disorders are treated in a step-wise manner. Initially, conservative treatment is used. Depending on the response, more aggressive interventions may be necessary. This usually takes the form of arthrocentesis. Arthrocentesis is used in the treatment of not only acute, closed, and locked TMJs but also various other temporomandibular disorders. Recently, the intra-articular injection of sodium hyaluronate after arthrocentesis was shown to have long-term palliative effects on TMJ symptoms. Synovial fluid consists of plasma and glycosaminoglycan, including hyaluronic acid derived from synovial cells. Sodium hyaluronate, the sodium salt of hyaluronic acid, is a high-molecular-weight polysaccharide and a major component of synovial fluid. This highly viscous substance has analgesic properties, lubricant effects, and anti-inflammatory actions; it causes cartilage formation and plays a role in the nutrition of avascular parts of the disc and condylar cartilage. We conclude that the intra-articular injection of sodium hyaluronate is effective for treating temporomandibular disorders.

Kole's Anterior segmental osteotomy of the mandible is commonly used to close an anterior open bite, to depress an elevated anterior dentoalveolar segment, or to retrude or advance a dentoalveolar segment. The procedure is often combined with an anterior maxillary segmental osteotomy to correct bimaxillary protrusion. We report 53-year-old woman who the extruded state of mandibular anterior alveolar segment was corrected using an mandibular anterior alveolar segmental osteotomy and dental implantation of the anterior maxilla. We planned to remove the old prosthesis, and then perform an anterior mandibular segmental osteotomy and implant restoration of the anterior maxilla. We suggest that anterior segmental osteotomy is very useful for rehabilitating edentulous patients with malaligned alveolar segment.

Renal ischemia is one of the most common causes of acute renal failure. Four factors related to the pathogenesis of acute renal failure are vasoconstriction, decreased glomerular filtration rate, tubular back leak of filtrate, and intratubular obstruction. The cellular response to renal ischemic insults include decreased content of adenosine trihosphate, lipid peroxidation induced membrane degradation, alteration in cellular pH, and calcium or phospholipase induced mitochondrial dysfunction. Much attention has been given to the role of increased cellular calcium as a pathogenetic contributor to cell injury during ischemia. Author studied the protective effects of calcium antagonists on cellular injury during renal ischemia in rat. To investigate the protective role of these agents, author measured the amount of malondialdehyde(MDA) and the enzyme activities of free radical scarvengers-superoxide dismutase(SOD), catalase and glutathione peroxidase from non-pretreated group and calcium antagonists pretreated groups in control, ischemia and reflow subgroups. The results were summerized as follows: 1) The amount of MDA in non-pretreated group was higher in the reflow compared with the control(<p<0.01). But, in all pretreated groups, there was no statistically difference in the amount of MDA. 2) The SOD activity in non-pretreated group was lower in both the ischemia and the reflow compared with the control (P<0.05). But, in both verapamil and trifluoperazine-pretreated groups, there was no statistically difference in the SOD activity. 3) Both catalase and glutathione peroxidase activities in non-pretreated group were lower in both the ischemia and the reflow compared with the control (P<0.05). But in all pretreated groups, there was no statically difference in both catalase and glutathione peroxidase activities. These results suggest that free radical mediated ischemic injury by renal artery clamp in rat can be protected by intraperitoneal pretreatment with calcium antagonists. As trifluoperazine has a protective effect in renal ischemia, the calcium activated calmodulin dependent enzyme may play a role in renal ischemic injury.

하악 과두 골절과 측두하악관절과의 관계

This review evaluates the literature on the relationship between mandibular condylar process fracture and temporomadibular joint (TMJ). The topic of condylar fracture generated more discussion and controversy than any other field of maxillofacial trauma associated with TMJ. Disturbance of occlusal function, devia-tion of mandible, internal derangements of TMJ, and ankylosis of the joint with resultant inability to move the jaw are sequelae of condylar process fracture. Thus it is necessary to understand how the masticatory system adapts to the structural alterations that accompany fractures of the mandibular condyle. Treatment of condylar process fracture include two methods ; closed treatment and open treatment. If one chooses totreat closed, one must understand that adaptations in the musculature, skeleton, and dentition will be necessary. Open treatment of condylar process fractures probably requires fewer adaptations within the masticatory system to provide a favorable functional outcome. However, one must weigh the risk of open surgery against the possible improvement in outcome. The risks are not just surgical risk, but biological risk as well, such as disruption of the blood supply to the condyle. This review presents relevant aspects of change of TMJ associated with condylar process fracture.

Ossifying fibroma is a rare, benign, fibro-osseous tumor of mesenchymal origin. It develops mainly in the mandible, where it is usually slow growing and asymptomatic, whereas in the maxilla and paranasal sinus, it is more aggressive. The vast majority are located in the posterior region of the mandible; however, ossifying fibroma involving the maxillary sinus is uncommon. It may reach a very large size and cause facial asymmetry. It shows a female predilection, and most cases are seen in the third and fourth decades of life. Radiographically, ossifying fibroma is radiolucent or radiopaque depending on the amount of calcification. Histologically, the tumor consists of a cementum-like or bony mass. Ossifying fibroma shares many histopathologic features with fibrous dysplasia. Their radiographic features may help to separate these entities when pathological differentiation is uncertain. It is important to differentiate ossifying fibroma from fibrous dysplasia. The treatment of ossifying fibroma involves its complete removal using curettage, enucleation, excision, or en bloc resection. This case report presents an unusual case of ossifying fibroma of the maxillary sinus. We describe a Caldwell-Luc operation with a lateral window approach for excision of an ossifying fibroma of the maxillary sinus.
