Periotest method as a measure of osseointegrated oral implant stability.

Oral implant stability is essential for optimal function. Results obtained from the Periotest measurement of the stability of 204 commercially pure titanium implants, consecutively placed in 22 maxillae and 24 mandibles according to the Brånemark procedure, are reported. Preliminary results suggest that the Periotest value of an oral implant is an objective and easily applied criterion for stability assessment. Since osseointegration is achieved gradually over time, this test may assist the clinician in deciding whether to extend the healing period before loading fixtures that seem clinically and radiologically integrated but give borderline Periotest values.

[Proposed use of natural teeth for management of a prosthetic case].

Authors describe the case of a periodontopathic patient having seriously involved lower incisors. They used a splinting system consisting of a lingual metal bar using close healthy teeth as an anchor, and using previously extracted teeth of the patient to get a good aesthetical, psychological and functional result.

[Periotest method for the quantitative assessment of occlusal loads].

Using a serial periotest unit we determined the periotest values for disclusion, slight centric occlusion, maximum intercuspation and axially in 102 subjects with a total of 1769 teeth in periodontally healthy dentitions. All teeth were grouped according to the criteria presence or lack of antagonist contact in maximum intercuspation, excentric abrasion facets and occlusal restorations, and statistically evaluated. The difference-normal range for physiologic occlusal loads can be assessed by comparative periotest measurements in disclusion and maximum intercuspation. Thus we have, for the first time, a quantitative, objectifiable parameter for the assessment of the "dimension of occlusion", which at the same time provides information on the functional load on the periodontia of antagonists. Premolar teeth with occlusal restorations tended to have significantly greater differences in the periotest values than teeth with natural occlusal surfaces. By comparing these values with the normal range of differences in the periotest value, a high degree of precision can be achieved in adjusting occlusal restorations. Axial measurements revealed a markedly higher shock absorbing capacity of the periodontia than horizontal measurements.

[Vertical movement of teeth following preparation for inlays with preservation of cavity walls].

By means of an indirect measuring procedure applied to 24 teeth including molars and premolars the extent of the teeth's vertical motion has been established. During the first three days after the neutralisation of the antagonistic contacts upon cavity preparation the scale and speed of the axial movement of the teeth were found to be larger than on the following four days (0.102 greater than 0.059 mm). It is recommended to apply cast fillings with a replacement of the occlusive area as quickly after the wax mould as possible because of the diminished gap due to the motion of the teeth.

[Gingival fibromatosis. A clinical, therapeutic and histopathological study of a new case].

The aetiopathogenesis, histology and clinical treatment of a rare case of familial gingival fibromatosis are analysed with particular emphasis on the relationship between the histological picture and the pathogenesis of the condition. In tackling the problem of treatment, the paper recommends the use of gingivectomy with an internal rather than the classic external chamfer.
