[Changes in the physical properties of Gingivamoll flexible gingival epithesis].

It was the purpose of this study to investigate variations in weight, volume, hardness, material density, adjustment and colour of Gingivamoll flexible gingival masks during a period of twelve months. Additionally, patients were inspected for potential infections of Candida albicans. Thirty-three gingival masks of nine patients were selected for the study. One third was placed into patients' mouths, one third was placed on stone models under room conditions and a third group was submerged under water. At baseline all gingival masks were examined and measured. For the first half of the year, measurements were recorded monthly and in the second half of the year at two months' intervals. Results showed a constant Shore-A hardness, volume and density. Gingival masks submerged under water kept their weight. The other masks, i. e. those placed into patients' mouths and those placed on plaster models, lost weight. Adjustment deteriorated at distal sites. Colour stability was not satisfactory. Tests for Candida albicans remained negative. It can be concluded that Gingivamoll flexible gingival masks can be used without serious problems for a period of twelve months.

[Posterior bite collapse. 2. Therapeutic proposals].

In the treatment of posterior bite collapse, the orthodontic phase consists of three steps: uprighting of molar teeth, leveling of the mandibular arch and closure of anterior diastemas. During and after orthodontic therapy, the maintenance of periodontal health is important. For patients in which there is a reduced periodontium, splinting should be accomplished after the teeth are moved into their desired position.

[A comparative analysis of the efficacy of combined treatment in generalized periodontitis of a moderate degree of severity using various splinting designs].

Immediate and late results of periodontitis treatment with the use of various types of joining in 74 patients are analyzed. Traditional casts were employed in 34 cases; in 40 patients fragmentary nonremovable casts with parapulpar fixation were used, as were adhesive one-piece, equatory, and intradental casts. The initial condition of the periodontium was similar in all the patients. Periodontal status was compared over the course of treatment with the use of different casts. Mathematical characteristics were used for analysis: periodontal and gingival indexes; osseous index and hygienic condition index, that were determined before, 30 days, and 12 months after treatment. Only two of the four studied indexes evidenced a reliable improvement of the condition after therapy and joining by traditional techniques, but the effect proved to be unstable, and 12 months after treatment both values significantly grew again. When traditional treatment modalities are used, alleviation of the inflammation and improvement of the hygienic condition of the oral cavity depend not so much on the type of joining but mostly on the initial status of the periodontium. A more manifest and stable reduction of the inflammation and improvement of the oral cavity hygienic status were observed in the patients treated with the use of present-day more physiologic cast designs. This evidence considerable advantages of these new designs vs. the traditional ones.

Management of pediatric mandibular fractures.

The incidence of mandibular fractures is rare in the pediatric population when compared to adults. Although the basic principles for management are the same as for the adult, certain anatomical features of the pediatric mandible warrant special attention. Problems such as mixed dentition, unerupted teeth, and ongoing growth in the mandible require careful diagnosis and planning in deciding on the proper treatment.

Clinical applications of the etched metal retainer.

This article presents the treatment of several patients directed at the prevention of periodontal disease and restoration of an occlusion from an eating disorder. The disruption of the harmony between the anterior and posterior determinants of occlusion can lead to the loss of teeth. The lack of anterior guidance can create a molar-guided occlusion producing unfavorable occlusal interferences with destructive balancing side prematurities. Conversely, if the posterior teeth are permitted to drift into unstable occlusal relationships, the posterior dentition would develop an irregular guidance despite a suitable anterior guidance. The goal of the profession is preventing occlusal deterioration or disharmony between the anterior and posterior occlusal determinants and restore compromised occlusions when necessary. Etched metal retainers were fundamental to the treatment of specific patients while patient selection and perceptive tooth preparation were essential for success.
