The clinical analysis of 462 patients (154 men and 308 women) with problems of implant therapy done at other clinics is reported. They visited the clinic for oral implant of the Tokyo Medical and Dental University Hospital during the period from January 1996 to March 2002. The results were as follows1) The majority of the patients (76.6%) were 40 to 69 years of age.2) Of the total patients, 26.8% had been referred from the other outpatient clinics in our hospital, 14.7% from private dental offices and 2.6% from attending doctors.3) There were 361 patients with complications related to the implant therapy. Seventy-six patients asked for second opinions concerned about a diagnosis or treatment recommendation. Thirty patients required maintenance of the implants.4) The most common complications observed were peni-implantitis (184 cases) . Prosthodontic compli-cations (72 cases) included framework/resin/veneering material fractures, screw loosening and fractures. There were implant fractures in 21 cases, sensory disturbance in 20 cases, problems related to sinus in 13 cases, problems of connected teeth in 30 cases and phonetic/esthetic complications in 10 cases.5) The types of problem implants were osseointegrated implants (196 cases), alumina-ceramic implants (74 cases), metallic blade type implants (35 cases), pin type implants (10 cases), subperiosteal implants (6 cases) and other implants.

A questionnaire survey was conducted to determine the information required by patients prior to providing informed consent for dental implant surgery. Questionnaires were distributed to 1,585 patients who visited the Tokyo Medical and Dental University Hospital for oral implants between January 2012 and December 2012, of which 1,159 (73%) valid questionnaires were collected. The results showed that preservation of an adjacent tooth was the reason that 32% of participants chose implant therapy. Over 70% of participants indicated that their main concerns regarding implant therapy were aftereffects of surgery, the number of years the implants would be in place, and treatment cost. Regarding knowledge about implant therapy, patients' most frequent reply was“ I do not know” when asked about postoperative pain, peri-implantitis, the importance of implant maintenance, and the relationship between general health and implant therapy. Fifty-nine percent of the patients recognized smoking as a risk factor for periodontal disease, of which 23% recognized smoking as a risk factor for implant therapy. Sixty-one percent of patients replied“ more than 20 years” when asked about the number of years that they believed the implants would be in place. This research identified the information required by patients in order to provide informed consent. Comprehensive information is required before informed consent is sought, as the majority of patients did not possess sufficient knowledge regarding implant therapy.

Evaluation of jawbone quality is very important for successful implant treatment; however, a method to evaluate bone quality of the jaw has not been established. Furthermore, at present, bone classifications are relatively rough and subjective methods for pre-operative assessment. This study compared the buccal and the lingual cortical bone mineral densities (BMD), and correlation trabecular BNID and cortical BMD by quantitative computed tomography (QCT). The subjects were 56 patients with mandibular distal extension defect (20 males, 17 pre-menopausal and 19 post-menopausal women;age range 30 to 79 years). The buccal and lingual cortical BMD and the trabecular BMD were measured by QCT. The difference and the correlation among the three groups were estimated. The results were as follows. 1. The buccal cortical BMD was significantly higher than the lingual cortical BMD in the male and pre-menopausal group. However, no significant difference was seen between the buccal and the lingual cortical BMD in the post-menopausal group. 2. The buccal cortical BMD correlated well with the trabecular BMD in the male group. 3. The buccal and the lingual cortical BMD did not correlate with the trabecular BMD in the pre-menopausal group. 4. The buccal cortical BMD correlated significantly with the trabecular BMD in the post-menopausal group. In conclusion, it is important to consider these tendencies of mandibular BMD in dental implant treatment.

Endogenous bacterial endophtalmitis is a rare but serious condition. It occurs in the eyeball when bacteria cross the blood-ocular barrier. We report a case of endogenous bacterial endopthalmitis arising from severe periodontitis without any noticeable systemic anamnestic.<br>A 53-year-old man was referred to the ophthalmology department in our university hospital complaining of reduced visual acuity in the right eye. His visual acuity was hand movements right and 0.7 left eye, respectively. His right eye showed hypopyon, dense vitreous opacity and retinal hemorrhages. Because of a finding peculiar to infective endocarditis from an echocardiography, we diagnosed the patient with endogenous endophthalmitis that caused infective endocarditis. Although there was no infection impact on his general condition, <i>α-streptococcus</i> was detected in his blood culture examination. Therefore, he was referred to our clinic for oral examination and care. He was diagnosed with chronic periodontitis and severe resorption of alveolar bone and gum swelling by oral examination and X-rays. The <i>α-streptococcus</i> was detected in a bacterial examination of the exudate from the gingival pocket. Fourteen teeth with severe periodontitis were extracted. The visual acuity in the right eye increased up to 0.07 at 6 months after the teeth extraction.<br>Though bacteriological identification was not accomplished completely, the endogenous endophtalmitis in the present case seemed to be affected with mitral regurgitation and vegetation, following infective endocarditis by oral <i>Streptococci</i>.
