- This 2·5-day workshop was organized by the International RDC/TMD Consortium Network of the International Association for Dental Research and the Orofacial Pain Special Interest Group of the International Association for the Study of Pain. Workshop participation was by invitation based on representation within the field, which included the Consortium Network, the Orofacial Pain Special Interest Group, the National Institute for Dental and Craniofacial Research, American Academy of Orofacial Pain, the European Academy of Craniomandibular Disorders, and the International Headache Society; other disciplines included radiology, psychology, ontology, and patient advocacy. The workshop members were divided into workgroups that reviewed core literature describing the properties of the RDC/TMD, provided recommendations for revision, and suggested relevant research directions. The goals of this workshop were to (i) finalize the revision of the RDC/TMD into a Diagnostic Criteria for Temporomandibular Disorders (DC/TMD), which would be more appropriate for routine clinical implementation, (ii) provide a broad foundation for the further development of suitable diagnostic systems for not only TMD but also oro-facial pain as well, and (iii) provide research recommendations oriented towards improving our understanding of TMD and oro-facial pain. This report provides the full description of the workshop and Executive Summary, and it acknowledges the participants and sponsors.

What you can and cannot see in TMJ imaging - an overview related to the RDC/TMD diagnostic system
- 2010
-
In: Journal of Oral Rehabilitation. - : Wiley. - 1365-2842 .- 0305-182X. ; 37:10, s. 771-778
-
Journal article (peer-reviewed)abstract
- Summary In the current version (I) of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD), imaging of the temporomandibular joint (TMJ) is not required for a diagnosis. Research has shown that radiological findings of the TMJ do not always support the clinical findings of the RDC/TMD diagnosis. But imaging should only be performed when it is known that it could contribute to (i) a proper diagnosis and (ii) treatment with a better prognosis. Several techniques are used to image the TMJ: panoramic radiography, plain radiography, conventional and computed tomography (CT), digital volume tomography or cone-beam computed tomography (CBCT), arthrography and magnetic resonance imaging (MRI). Osseous changes are best visualized in tomography, and the newly developed CBCT is a promising method but must be evaluated in a comparative analysis with other tomographic techniques. And although MRI is the method of choice for imaging the disc, a systematic review found the evidence grade for the diagnostic efficacy of MRI to be insufficient. Today, there is no clear evidence for when TMD patients should be examined with imaging methods. Future research designs should be randomized controlled trials where various radiological examination findings are analysed in relation to therapeutic outcome. In future versions of the RDC/TMD diagnostic system, recommended radiographic techniques must be evaluated and defined, diagnostic criteria well defined and observers calibrated.

An exploratory survey of diagnostic methods for bone quality assessment used by Brazilian dental implant specialists
- 2010
-
In: Journal of Oral Rehabilitation. - : Wiley. - 1365-2842 .- 0305-182X. ; 37:9, s. 698-703
-
Journal article (peer-reviewed)abstract
- Bone quality (BQ) has been described as an important predictor for the outcome of dental implant treatment. It is, however, unclear how this factor is assessed in the dental practice routine. The aim of this study was to investigate what Brazilian dental implant specialists know and understand about BQ, if they include BQ assessments in their treatment planning and which methods they use to assess BQ. A questionnaire was posted to Brazilian dental implant specialists, containing open and closed questions about their knowledge and understanding of BQ assessment, and 221 answered the questionnaire. Data were gathered and methods for BQ assessment were grouped using hierarchical cluster analysis. Answers about BQ knowledge and understanding were categorized into quantity of cortical and marrow bone (n = 72), density (n = 55), type of bone (n = 35), bone height (n = 30), bone thickness (n = 27), primary stability (n = 24) and other less common categories. BQ assessment was judged relevant to be considered a selection criterion for implant treatment. Overall frequency analysis showed that methods were roughly divided into usual (n > 170) and unusual methods (n < 9). Cluster analysis grouped BQ assessment methods into four clusters: unusual methods (DEXA, resonance frequency, Periotest and occlusal radiography), perioperative methods (peak insertion torque and tactile perception), sectional imaging (computed tomography) and plain films (periapical and panoramic radiographs). No consensus on BQ understanding or the clinical application of methods to assess BQ was found in this survey. The selection of methods shows a clear natural grouping from basic to advanced strategies for BQ assessment by Brazilian specialists in dental implants.

Characteristics of implant-CAD/CAM abutment connections of two different internal connection systems
- 2012
-
In: Journal of Oral Rehabilitation. - : John Wiley & Sons. - 1365-2842 .- 0305-182X. ; 39:5, s. 391-398
-
Journal article (peer-reviewed)abstract
- Titanium or zirconium computer-aided design/computer-aided manufacturing abutments are now widely used for aesthetic implant treatments; however, information regarding microscopic structural differences that may influence the biological and mechanical outcomes of different implant systems is limited. Therefore, the characteristics of different connection systems were investigated. Optical microscopic observation and scanning electron microscopy showed different characteristics of two internal systems, namely the Astra Tech and the Replace Select system, and for different materials. The scanning electron microscopic observation showed for the Astra Tech that the implant-abutment interface seemed to be completely sealed for both titanium and zirconium abutments, both horizontally and sagittally; however, the first implant-abutment contact was below the fixture top, creating a microgap, and fixtures connected with titanium abutments showed significantly larger values (23·56μm±5·44 in width, and 168·78μm±30·39 in depth, P<0·001). For Replace Select, scanning electron microscopy in the sagittal direction showed that the sealing of titanium and zirconium abutments differed. The seal between the implant-titanium and implant-zirconium abutments seemed to be complete at the butt-joint interface; however, the displacement of the abutment in relation to the fixture in the lateral direction was evident for both abutments with no statistical differences (P>0·70), creating an inverted microgap. Thus, microscopy evaluation of two commonly used internal systems connected to titanium or zirconium abutments showed that the implant-abutment interface was perfectly sealed under no-loading conditions. However, an inverted microgap was seen in both systems, which may result in bacterial accumulation as well as alteration of stress distribution at the implant-abutment interface.

Guidelines and recommendations for assessment of somatosensory function in oro-facial pain conditions - a taskforce report
- 2011
-
In: Journal of Oral Rehabilitation. - : Blackwell Publishing Ltd.. - 1365-2842 .- 0305-182X. ; 5:38, s. 366-394
-
Journal article (peer-reviewed)abstract
- Summary The goals of an international taskforce on somatosensory testing established by the Special Interest Group of Oro-facial Pain (SIG-OFP) under the International Association for the Study of Pain (IASP) were to (i) review the literature concerning assessment of somatosensory function in the oro-facial region in terms of techniques and test performance, (ii) provide guidelines for comprehensive and screening examination procedures, and (iii) give recommendations for future development of somatosensory testing specifically in the oro-facial region. Numerous qualitative and quantitative psychophysical techniques have been proposed and used in the description of oro-facial somatosensory function. The selection of technique includes time considerations because the most reliable and accurate methods require multiple repetitions of stimuli. Multiple-stimulus modalities (mechanical, thermal, electrical, chemical) have been applied to study oro-facial somatosensory function. A battery of different test stimuli is needed to obtain comprehensive information about the functional integrity of the various types of afferent nerve fibres. Based on the available literature, the German Neuropathic Pain Network test battery appears suitable for the study of somatosensory function within the oro-facial area as it is based on a wide variety of both qualitative and quantitative assessments of all cutaneous somatosensory modalities. Furthermore, these protocols have been thoroughly described and tested on multiple sites including the facial skin and intra-oral mucosa. Standardisation of both comprehensive and screening examination techniques is likely to improve the diagnostic accuracy and facilitate the understanding of neural mechanisms and somatosensory changes in different oro-facial pain conditions and may help to guide management.

From brain to bridge: masticatory function and dental implants
- 2012
-
In: Journal of Oral Rehabilitation. - : Wiley. - 0305-182X .- 1365-2842. ; 39:11, s. 858-877
-
Research review (peer-reviewed)abstract
- Masticatory function is an important aspect of oral health, and oral rehabilitation should aim to maintain or restore adequate function. The present qualitative review is the joint effort of a group of clinicians and researchers with experiences ranging from basic and clinical oral neuroscience to management of patients with dental implants. The aim is to provide a short summary for the clinician of the many aspects related to masticatory function (including quality of life) and rehabilitation with dental implants. While there are many reviews on the tissue responses to dental implants and technical aspects, the functional aspects have received relatively little focus.

Comparison of speech intelligibility, articulation and oromyofunctional behaviour in subjects with single-tooth implants, fixed implant prosthetics or conventional removable prostheses
- 2012
-
In: Journal of Oral Rehabilitation. - : Wiley-Blackwell. - 1365-2842 .- 0305-182X. ; 39:4, s. 285-293
-
Journal article (peer-reviewed)abstract
- The purpose of this controlled study was to determine the impact of a single-tooth implant, fixed implant prosthesis and completely removable dental prosthesis on intelligibility, articulation and oromyofunctional behaviour. Additionally, the self-perceived overall satisfaction of the dental replacements and the effect on speech was questioned. Objective (acoustic analysis) as well as subjective assessment techniques (perceptual evaluation) were used. The satisfaction of single-tooth implant group was very high (100%) followed by a satisfaction of 87% for the fixed implant prosthesis group and 68% for the removable prosthesis group. The results of the phonetic analyses revealed a normal intelligibility and oromyofunctional behaviour in the three groups of dental replacements. Only one type of articulation disorders was observed in the single-tooth implant group, followed by three types of disorders in the removable prosthesis group and six types of disorders in the fixed implant prosthesis group. In this last group, not only 87% of the subjects showed distortions of one or more consonants but also most consonants of the Dutch language were disturbed in comparison with the single-tooth implant and removable prosthesis users. Special attention must be paid to the fricative /s/ because in more than 50% of all groups, this sound is disturbed.

Current challenges in successful rehabilitation with oral implants
- 2011
-
In: Journal of Oral Rehabilitation. - : John Wiley & Sons. - 1365-2842 .- 0305-182X. ; 38:4, s. 286-294
-
Journal article (peer-reviewed)abstract
- Very high survival/success rates have been reported for implant treatment, irrespective of the prosthetic type of reconstruction, be those full arcs, partial dentures, combined tooth implants or single crowns. However, survival/success is commonly reported in simple Cumulative Survival/Success Rate (CSR) tables only that may overestimate the true clinical outcome; furthermore, future challenges to clinical success may originate from too rapid launching of untested novelties or recommendations to apply too bold clinical procedures, potential problems that are summarised in the present paper.

Prophylactic antibiotic regimen and dental implant failure : a meta-analysis
- 2014
-
In: Journal of Oral Rehabilitation. - : John Wiley & Sons. - 1365-2842 .- 0305-182X. ; 41:12, s. 941-956
-
Journal article (peer-reviewed)abstract
- The aim of this meta-analysis was to investigate whether there are any positive effects of prophylactic antibiotic regimen on implant failure rates and post-operative infection when performing dental implant treatment in healthy individuals. An electronic search without time or language restrictions was undertaken in March 2014. Eligibility criteria included clinical human studies, either randomised or not. The search strategy resulted in 14 publications. The I(2) statistic was used to express the percentage of the total variation across studies due to heterogeneity. The inverse variance method was used with a fixed- or random-effects model, depending on the heterogeneity. The estimates of relative effect were expressed in risk ratio (RR) with 95% confidence interval. Six studies were judged to be at high risk of bias, whereas one study was considered at moderate risk, and six studies were considered at low risk of bias. The test for overall effect showed that the difference between the procedures (use versus non-use of antibiotics) significantly affected the implant failure rates (P = 0·0002), with a RR of 0·55 (95% CI 0·41-0·75). The number needed to treat (NNT) to prevent one patient having an implant failure was 50 (95% CI 33-100). There were no apparent significant effects of prophylactic antibiotics on the occurrence of post-operative infections in healthy patients receiving implants (P = 0·520). A sensitivity analysis did not reveal difference when studies judged as having high risk of bias were not considered. The results have to be interpreted with caution due to the presence of several confounding factors in the included studies.
