Result & discussion: Current status of implant prosthetics in Japan (9)
While the literature includes reports of frequent IOD-related prosthetic complications such as attachment-related compromised retention, detachment or fracturing of denture teeth, relining, and attachment damage, this survey showed a somewhat different trend. It can be inferred that these results differ from actual complication trends because they constitute responses to cases sent to labs as repair requests, and because the survey targeted dental technicians. The causes of this phenomenon can be found in responses to other questions as described above. In short, the questionnaire suggested the possibility that inadequate awareness of prosthetics is making IOD complications in Japan more complex, with issues including the comparatively frequent use of resin bases, problems with implant location and orientation, and inadequate consideration of occlusion by dentists.
Finally, technicians gave voice to the several requests for dentists, who are their customers, as a result of their daily experiences accomplishing implant laboratory procedures (Q14) (Figure 9). These included asking dentists to use suitable implant location and orientation (31.8%), to allow technicians to participate and consult with technicians from the treatment planning stage (28.3%), to improve consideration of soft tissue as well as its condition (21.8%), and to add more in-depth knowledge of prosthesis and occlusal design (14.5%). As observed, implant location and orientation issues in particular not only complicate technical work, but may also cause a variety of complications after the initiation of loading. For cases involving a broad range of implant prostheses and occlusal reconstruction, if not all cases, the dental technicians should be a part of the team from the treatment planning stage to enable restoration-driven implant treatment in the true sense of the term. At the same time, a dentist with an extensive understanding of prosthodontics should play the leading role in treatment of such cases. This survey succeeded in identifying prosthetic problems by examining implant prosthetic complications from the dental technician’s perspective. As stated in the description of the survey’s purpose, it is hoped that dentists make use of this report to reaffirm prosthetic concepts and awareness so that there is achievement of predictable implant prosthetic treatment.
