JOURNAL FREE ACCESSThis survey classified the issues involved in promoting the regular check-up system in dental clinics. The survey was conducted in two parts: interviews with 39 dental clinics and a questionnaire survey of 5, 129 patients (response rate: 56.8%) .
The results are summarized as follows:
1. Among the dental clinics that participated in this survey, the proportion of regular patients, the number of dental hygienists working at clinics, and the number of patients per day were higher than those of the national average.
2. The demographic patterns of regularly attending patients were“female, aged under 14 years and students or public servants”.
3. Satisfaction with the technical competence of hygienists has the strongest correlation with regular-ity of visiting. The degree of correlation was about twice that of the correlation with technical competence of the dentist.
4. Patients' priorities for improving dental services to enhance satisfaction were treatment charges, appointment system, and attitude of staff and doctors toward welcoming the patients.View full abstractDownload PDF (839K) -

JOURNAL FREE ACCESSThis study compared the adaptation of a conventional and an electroformed porcelain-fused-to-metal crown. A master model was selected from an ITI implant with a solid abutment (height: 4 mm) . Conventional cast metal frameworks of 0.7 mm thickness were prepared with a high noble metal alloy (Degudent U, Degussa) for porcelain fusing (n=5) .
Electroformed frameworks of 0.2 mm thickness were determined using pure gold deposition on the abutment using the Auro-Galva-Crown system (AGC, Wieland) (n=5) . Subsequently, a porcelain (Super Porcelain AAA, Noritake) was fused to each framework. Internal gaps between the framework and its abutment were determined using the thickness of a silicone fit checking material.
The gaps were measured both before and after porcelain fusing. The thicknesses of the silicone layer of the electroformed and the conventional porcelain-fused-to-metal crown were 34.6 and 38.5, μm at the margin, 33.2 and 39.6, μm at the internal slope, 22.0 and 33.0 μm at the axial, 58.6 and 65.1, μm at the occlusal, respectively. Three-way analysis of variance revealed that the mean gaps in the electroformed porcelain-fused-to-metal crown were significantly thinner than those in the conventional porcelain-fused-to-metal crown (p<0.05) . The electroformed porcelain-fused-to-metal crown showed better adaptability than the conventional porcelain-fused-to-metal crown regardless of porcelain fusing.View full abstractDownload PDF (2794K) -

JOURNAL FREE ACCESSThe 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 follows
1) 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.View full abstractDownload PDF (1129K) -

JOURNAL FREE ACCESSWe have carried out temporary silicone implants after diskectomies or arthroplasties in temporomandibular joint surgeries to avoid postoperative adhesion and to maintain articular space. We evaluated 19 joints in 15 patients who had received dacron-reinforced silicone implant after silicone sheet removal through follow-up for at least 6 months. The cases included temporomandibular joint disorder (10 joints in 9 patients), psoriatic arthritis (2 joints in 1 patient), ankylosis (4 joints in 3 patients) and synovial chondromatosis (2 joints in 2 patients) . On the basis of the criteria of temporomandibular dysfunction for the results, they were classified as bad (4 patients) . It is thought that factors other than the implant are related to the bad results in the postoperative evaluation. In this study, lymphadenopathy induced by exfoliated silicone debris could not be confirmed. The temporary silicone implant in the temporomandibular joint was thought to be useful.View full abstractDownload PDF (600K) -
