Dental implant surgery commonly proceeds in two stages. It is generally accepted that bone loss around implants does not occur at stage-II surgery because implants do not receive mechanical loading. However, early marginal bone loss around implants occasionally does occur during the healing period. Genetic polymorphisms in the interleukin-1 (IL-1) gene have(More)
Chronic periodontitis (CP) is caused by enhanced resorption of the alveolar bone supporting the teeth and is associated with intraoral inflammation after infection with certain bacteria. The VDR gene polymorphism was reported recently to be deeply related to the occurrence of tuberculosis and infection of chronic hepatitis B virus. This may be interpreted(More)
PURPOSE This study investigated the relationship between calcitonin receptor (CTR) genotype and buccal marginal bone loss observed at stage II surgery for endosseous implants. MATERIALS AND METHODS A total of 237 implants were placed in 35 patients; 89 implants were placed in maxillae and 148 implants in mandibles. The CTR genetic polymorphism was(More)
An 11-year-old Japanese girl noticed a small nodule, with mild tenderness, on the right index finger 5 years before visiting our outpatient clinic. She had no familial history of neurofibromatosis or past history of traumatic injury at the site of the tumor. Physical examination revealed a slightly elevated, subcutaneous, nodular tumor in the volar aspect(More)
We have created a new way of reanimating the face, involving transposition of the masseter muscle combined with tensor fascia lata, and using the zygomatic arch as a trochlea to reconstruct the inferior facial paralysis. We used it on five patients who had facial palsy after excision of malignant parotid tumours. The wide skin defect that exposed the(More)
When increased contraction of the levator muscle accompanied by the superior rectus muscle compensates for aponeurotic blepharoptosis, increased contraction of the inferior rectus muscle for foveation retracts the lower eyelid through the capsulopalpebral fascia, showing the lower sclera. We hypothesized that in patients with aponeurotic blepharoptosis, the(More)
PURPOSE At stage II surgery during dental implant treatment, early marginal bone loss around the implant occasionally occurs despite a lack of apparent causal events, and the etiology of this bone loss is unclear. This study was designed to investigate whether the bone morphogenetic protein-4 (BMP-4) genetic polymorphism is associated with early marginal(More)
We have created an alternative method for facial reanimation. This new surgical procedure involves masseter muscle transposition combined with tensor fascia lata, and the zygomatic arch is used as a trochlea to achieve reconstruction of inferior facial paralysis. This method was used on five patients with facial palsy after excision of a malignant parotid(More)
BACKGROUND The digital triangular island flap is one of the most useful types of flap for repairing soft-tissue loss at the fingertip, because it is sensate and has glabrous skin. However, this type of flap has several disadvantages, including limited length of advancement and limited flap size. METHODS We have developed a new type of dorsally extended(More)
