Maintenance and the clinical evaluation of periodontal patients in Konus-Telescope denture

In order to assess by periodontal evaluation the changes that might occur with time in the abutment teeth and periodontal tissues when Konus-Telescope dentures are used as that final treatment of periodontal disease, the dentures (15 units) were placed in 13 patients with missing tooth and periodontal disease and findings at the time of denture placement and 30 months after the placement were compared. The number of cases that exhibited significant changes in hygiene level, tissue inflammation and periodontal pocket depth of the abutment teeth after 30 months was very small, while as many as 85.2% of the abutment teeth showed decrease in tooth mobility. Increase in tooth mobility was not detected in any of the cases. In addition, X-ray examination revealed tendencies toward improvement of the periodontal ligament and remission of alveolar bone resorption in many of the cases. These results suggest that Konus-Telescope denture is highly offers protection of the residual periodontal tissues through its secondary splint action.

A 5-year longitudinal study of cantilevered fixed partial dentures compared with removable partial dentures in a geriatric population

Prosthesis function and dental conditions were observed for 5 years in 27 elderly patients treated with mandibular cantilevered fixed partial dentures (FPDs) and in 26 elderly patients treated with distal-extension removal partial dentures (RPDs). All patients were treated with a complete upper denture. The patients were assigned randomly into two treatment groups that had the same composition with regard to sex, age, and distribution of teeth. The patients were under supervised oral hygiene and prosthodontic care. Clinical examination of prostheses, masticatory system, periodontal status, and caries was carried out yearly. Oral hygiene was good, and the periodontal status was maintained in both groups. Caries was observed six times more frequently in the RPD group than in the group with fixed restorations, however. Occlusal and functional conditions deteriorated in the RPD group only. Eight of 42 fixed partial dentures (19%) failed; of these, six were recemented with composite resin. Generally the need for dental and prosthetic follow-up treatment was more pronounced in the RPD group than in the FPD group.

Longitudinal study on periodontal conditions in healthy elderly people in Japan

OBJECTIVES: A strategy for the control of periodontal disease progression is required to prevent tooth loss in older people. However, detailed epidemiological data on periodontal conditions in elderly people is limited. The purpose of the present study is to describe the natural history of periodontal disease and to evaluate the intraoral factors relating to the disease progression in systemically healthy elderly people. METHODS: In the cross-sectional study, 599 and 162 subjects aged 70 and 80 years, respectively, were examined. Of those subjects aged 70 years, 436 (73%) participated in the 2-year longitudinal study. Pocket depth (PD) and attachment level (AL) were measured for all functioning teeth at six sites per tooth. In the cross-sectional study, AL of 4 mm or greater and 7 mm or greater were defined as moderate and severe disease, respectively. In the longitudinal study, a change in AL of 3 mm or greater at each site was defined as periodontal disease progression. RESULTS: In the cross-sectional study, 97.1% of the subjects had at least one site of AL of 4 mm or greater (4+ mm). The prevalence of AL of 7 mm or greater (7+ mm) was 47.9%, with 2.8 affected teeth per person in those with AL 7+ mm. These findings reveal that periodontal disease is extremely widespread in the elderly population. However, very few had many teeth with severe periodontal conditions. In the longitudinal study, 75.1% experienced attachment loss of 3 mm or greater (3+ mm) during the 2-year study period. Of those subjects who experienced attachment loss, a mean of 4.7 teeth exhibited attachment loss. Multivariate logistic regression showed that both the highest AL in each tooth at baseline and abutment teeth for removable partial dentures were significantly related to periodontal disease progression as well as tooth loss incidence. CONCLUSIONS: These results suggest that teeth with poor periodontal conditions as well as abutment teeth for removable partial dentures were significant intraoral factors relating to periodontal disease progression as well as tooth loss.
