Periotest method: Implant-supported framework fit evaluation in vivo

The Journal of Prosthetic Dentistry, 1998
In implant prosthodontics an accurate fit of the framework to the supporting implants is paramount. However, microgaps occur, unknown to the clinician until complications arise that implicate errors in fit. Therefore prosthodontics would welcome a tool or instrument that provides an objective evaluation of the fit at the implant prosthodontic interface.

Predictive Value of Periotest® Assessment for Failure of Mini Dental Implants Supporting Maxillary Overdentures: A Pilot Study

Journal of Stomatology, Oral and Maxillofacial Surgery
Objective: This prospective cohort study assesses the long-term (5 years) clinical outcome of mini dental implants (MDIs) supporting maxillary overdentures with Periotest® and explores the applicability of Periotest® values (PTV) to predict implant ...

Correlations between photogrammetric measurements of tooth mobility and the Periotest method

Acta Odontologica Scandinavica, 2011
The purpose of the present study was to investigate whether or not the quantitative Periotest values of anterior teeth correlate with quantitative metric values of tooth mobility under vertical (VL) and horizontal load (HL) in periodontally healthy subjects.Thirty-one subjects with good periodontal conditions were included and subjected to two ...

The Periotest method for determining implant success.

The Journal of oral implantology, 1992
The purpose of this paper is to show that the currently accepted methods for the determination of implant stability are unpredictable. It describes those techniques that are currently utilized for the assessment of implant success and discusses the problems they present.

[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.

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.

[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 ...
