This present research study was carried out to develop and evaluate the subcutaneous implants of chitosan for the administration of tramadol. Tramadol is one of the centrally acting analgesics with opioid agonist properties and can be safely used in such condition without the side effects. Rod shaped implants of 1 mm diameter and 2.7 mm in length were prepared by extrusion method, using a speci...

Surgical correction of hallux limitus or degenerative articular disease of the first metatarsophalangeal joint (MPJ), whether as singular conditions or in the face of concomitant hallux abducto valgus, is a dilemma with which foot surgeons have struggled with for almost a century. The ideal procedure would provide adequate pain-free motion of the first MPJ without shortening the hallux or unwei...

A total of 264 implants was placed in 143 patients using different immediate or delayed-immediate implant placement techniques in 12 different centers participating in a prospective multicenter study. The reason for tooth extraction was evaluated; bone quality and quantity were classified; socket depths were registered; and data on implant type, size, and position were collected. One hundred th...

In hereditary retinal diseases photoreceptors progressively degenerate, often causing blindness without therapy being available. Newly developed subretinal implants can substitute functions of photoreceptors. Retina implant extraocular surgical technique relies strongly on cochlear-implant know-how. However, a completely new surgical approach providing safe handling of the photosensor array had...

BACKGROUND Hajdu-Cheney Syndrome (HCS) is a rare hereditary bone metabolism disorder characterized by acro-osteolysis, short stature, craniofacial changes, periodontitis and premature tooth loss. Extensive search of the current literature revealed no reports of implant placement in patients with HCS. CASE REPORT A 22-year old woman with osteoporosis, generalized advanced chronic periodontitis...

The aim of the present case report was to demonstrate vertical gain in posterior resorbed mandible utilizing use an Allograft Customized Bone Block. presents a 66-year-old healthy female nonsmoker who lost her right mandibular molars long time ago. In past, she had implant placement, which failed due fracture implant. Due high risk nerve damage, left jaw and completely covered with bone. Since ...

mandibular canal is the most important anatomical landmark in the body of mandible which always must be considered for implant surgery in posterior mandibular region. damage to vessels and inferior alveolar nerve that passes through the mandibular canal can cause problems such as hemorrhage and neurosensory disturbances. damage to the mandibular canal can occur during implant surgery. depending...

Questions remain whether postoperative infections and implant failure can be reduced with the use of antibiotics. Especially, when its routine use can cause adverse effects and may contribute to the development of antibioticresistant bacteria. Moreover, there is no consensus regarding appropriate dosage regimen of antibiotics to prevent bacterial infection in implant dentistry. To determine eff...

Hip resurfacing has been considered a good treatment option for younger, active osteoarthritis patients. However, there are several identified issues concerning risk for neck fractures and issues related to current metal-on-metal implant designs. Neck-preserving short-stem implants have been discussed as a potential alternative, but it is yet unclear which method is better suited for younger ad...

PURPOSE This study evaluated the initial stability of different implants placed above the bone level in different types of bone. MATERIALS AND METHODS As described by Lekholm and Zarb, cortical layers of bovine bone specimens were trimmed to a thickness of 2 mm, 1 mm or totally removed to reproduce bone types II, III, and IV respectively. Three Implant system (Brånemark System® Mk III TiUnite...
