"Standardized" radiographs acquired in paralleling technique serve for monitoring of marginal bone levels around endosseous implants. Under clinical conditions, parallel adjustment of the film to the implant is beset with great difficulties. A mathematical model matching clinical conditions was developed to evaluate projection geometry within an interval of clinically relevant angulations (+/- 10 degrees from parallel position). Radiographs of two implants (Frialit 2, Friadent AG, Mannheim… Expand
A paralleling technique modification to determine the bone crest level around dental implants.
TLDR
Precision was very high for both methods and accurate enough for clinical use and the influence of the reference points' definition of objects to be measured by using both the original and the modified radiographic techniques. Expand

TLDR
Experimental results indicate that the analytical algorithm introduced is capable of providing geometrical information important for a variety of applications, and has to be enhanced by means of automated image analysis and processing methods. Expand
Acrylic Customized X-Ray Positioning Stent for Prospective Bone Level Analysis in Long-Term Clinical Implant Studies
TLDR
The X-ray positioning device produced reproducible images in different moments and was suitable for comparative clinical examinations of marginal bone as it was convenient to perform reliable linear measurements. Expand
Accuracy of vertical height measurements on direct digital panoramic radiographs using posterior mandibular implants and metal balls as reference objects.
OBJECTIVES Conventional panoramic radiography, a widely used radiographic examination tool in implant treatment planning, allows evaluation of the available bone height before inserting posteriorExpand
A radiographic-based method for marginal bone loss measurement in dental implants
TLDR
A semi-automatic approach to establish the degree of osseointegration of dental implants based on radiographic images is presented, and results are well correlated with the manual measures. Expand
Spatial relation between a rigid (digital) intraoral X-ray receptor and longitudinal axes of maxillary teeth
TLDR
The purpose of this study was to quantify the existing (inevitable) angle which in intraoral radiology appears between tooth length axis and receptor caused by the anatomical situation, and investigate the effects of the realistic angulation on these image deteriorating factors. Expand
Ex vivo radiographic tooth length measurements with the reference sphere method (RSM)
TLDR
A reference-based radiographic “reference sphere method” (RSM) for accurate length measurements in (dental) projection radiographs for the assessment of tooth length in dry human mandible sections is evaluated and remains errors are mainly due to incorrect landmark definition. Expand
A method for segmentation of dental implants and crestal bone
TLDR
A new method aimed to produce an accurate segmentation of dental implants and the crestal bone line in radiographic images is presented and it was demonstrated that the method achieved a precise segmentations of the intended structures. Expand
A new digital tool for radiographic bone level measurements in longitudinal studies
TLDR
This study showed that the use of the original, direct technique (ImageJ) resulted in markedly biased radiographic bone level at 30° angle, while the proposed indirect length-adjusted technique ( imageJ plugin) did not. Expand
The accuracy and reliability of radiographic methods for the assessment of marginal bone level around oral implants.
TLDR
The selected imaging techniques showed an acceptable accuracy for peri-implant bone level measurements with an overall error of less than 0.5 mm. Expand

TLDR
The purpose of the present study was by means of an experimental model to analyze the influence upon alveolar bone height measures around osseointegrated implants of buccolingual bone dimensions as well as angulations of fixture axis to central X-ray beam. Expand
Radiographic verification of implant abutment seating.
TLDR
Maintaining the tube head to less than 20 degrees from perpendicular to the long axis of the implant resulted in a diagnostic radiograph, regardless of the angle of the film. Expand
Clinical and radiographic evaluation, following delivery of fixed reconstructions, at GBR treated titanium fixtures.
TLDR
Fixture stability, radiographic marginal bone levels and peri-implant soft tissue status were evaluated and results showed no significant difference in the rate of bone loss following functional loading between membrane treated and control fixtures. Expand
In vivo determination of radiographic projection errors produced by a novel filmholder and an x-ray beam manipulator.
TLDR
The new measuring system proved to be accurate enough to measure the in vivo projection errors between repeated radiographs produced with the new filmholder and x-ray beam manipulator and are markedly smaller than all in vivo and in vitro errors previously reported in the literature. Expand
Reliability of a paralleling instrument for dental radiographs.
TLDR
A mathematic procedure to assess the global angular projection error of any similar coupled x-ray cone-film holder device is proposed and should be routinely used to check superimposability of serial radiographs before density quantification or subtraction. Expand

An innovative improvement on existing methods using conventional and custom-made components, shows a procedure to accurately and simply standardize follow-up radiographs, for both free-standing and bar designs for mandibular implant-supported overdentures. Expand

TLDR
In a laboratory experiment osseointegrated implants inserted to mandibular bone models were radiographed and the implant with its threaded pattern earned as an ideal gauge when measuring the perimplant bone height. Expand

TLDR
The radiographic follow-up of 33 implants loaded for up to 4 years, has revealed a most favourable maintenance of marginal bone around the conical collar, with a mean marginal bone loss of 0.32 mm mesially and 0.34 mm distally for the whole group. Expand
