[Periotest method for diagnosis of marginal inflammations].

Deutsche zahnarztliche Zeitschrift, 1990
Using traditional recognized parameters, 271 periodontal cases were examined to determine the degree of inflammation and attachment loss. The values were compared to the Periotest-instrument. The correlation between the two methods concerning the inflammatory process was significant to insignificant.

Theoretical percussion force of the periotest diagnosis.

The International journal of oral & maxillofacial implants, 1998
The Periotest percussion force acting on a dental implant was estimated by assuming a mass-spring-dashpot model of the implant-bone system constructed on the basis of a clinical experiment. A theoretical value of about 10 N, comparable to hitherto reported experimental values, was obtained for an osseointegrated implant of about 1 g.

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

Deutsche zahnarztliche Zeitschrift, 1991
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 ...

Influence of the implant abutment on the Periotest value: an in vivo study.

Quintessence international (Berlin, Germany : 1985), 2002
Periotest values for dental implants depend on the type of prosthetic abutment utilized for the restoration. If Periotest value cannot be measured at the single crown, the Periotest values used for comparison must be derived from the same type of superstructure.Fifty-nine patients were selected from a regular follow-up program.

[Comparative studies on periodontal indexes with particular to the Periotest method].

Deutsche zahnarztliche Zeitschrift, 1990
40 patients from both gender were examined to determine if there is a correlation between periodontal indices and periotest values. As a result we were able to show that the pocket depth correlates with the periotest values for all tooth groups. On the other hand SBI correlates with the periotest values only for the premolars in upper and the front in ...

Periotest to monitor osseointegration and to check the occlusion in oral implantology.

The Journal of oral implantology, 1993
This paper reports on Periotest, its technique's history, and its possible applications. Periotest is a new diagnostic method, developed by an interdisciplinary research group embracing dentists, physicists, mathematicians, and computer engineers. Periotest will--apart from periodontal questions--mainly assist oral implantology.

Measuring abutment/implant joint integrity with the Periotest instrument.

The International journal of oral & maxillofacial implants, 1999
Maintenance of the integrity of the abutment/implant interface is essential and is dependent on the abutment screw retaining a preload. Evaluation of this joint is usually done by manual assessment. The purpose of the current study was to determine whether the Periotest instrument could be used to evaluate abutment screw loosening.

Periotest method as a measure of osseointegrated oral implant stability.

The International journal of oral & maxillofacial implants, 1991
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.

[Relevance of the Periotest as a function of root shape and cross-section].

Deutsche zahnarztliche Zeitschrift, 1990
In the laboratory extracted teeth were provided with an artificial periodontal ligament. Subsequently periotest values were measured around the complete circumference of the crown. When plotted in a graph the relationship between root cross-section and damping value can be demonstrated.
