Cost-utility analysis of an implant treatment in dentistry

Background: When dealing with the replacement of one missing tooth, the patient has the option of choosing between different types of treatment interventions. Several important factors play a role in his decision-making process, including his limited financial means and his efforts to solve the problem of missing teeth as effectively as possible. The main goal of the study is the economic-clinical evaluation of implant treatment, as a surgical-prosthetic method in dentistry, in case of replacement of one missing tooth of the molar area. Methods: Cost-utility analysis from the patient’s perspective is used for evaluation. The selected comparator is a purely prosthetic solution with the help of a three-unit fixed dental prosthesis. Cost-utility analysis is modelled using Markov models, which consider a 30-year time horizon. Results: Based on the results of modelling, the intervention evaluated by the patient, i.e. treatment with the help of implant-supported single crown, brings exactly 15.31 quality-adjusted prosthesis years (QAPY) after 30 years. The value of incremental cost-utility ratio amounted to USD − 1434. Conclusion: The results of the cost-utility analysis suggest that implant treatment with an implant-supported single crown is more cost-effective than treatment with the three-unit fixed dental prosthesis.

Clinical Utility of Body Surface Potential Mapping in CRT Patients

This paper reviews the current status of the knowledge on body surface potential mapping (BSPM) and ECG imaging (ECGI) methods for patient selection, left ventricular (LV) lead positioning, and optimisation of CRT programming, to indicate the major trends and future perspectives for the application of these methods in CRT patients. A systematic literature review using PubMed, Scopus, and Web of Science was conducted to evaluate the available clinical evidence regarding the usage of BSPM and ECGI methods in CRT patients. The preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement was used as a basis for this review. BSPM and ECGI methods applied in CRT patients were assessed, and quantitative parameters of ventricular depolarisation delivered from BSPM and ECGI were extracted and summarised. BSPM and ECGI methods can be used in CRT in several ways, namely in predicting CRT outcome, in individualised optimisation of CRT device programming, and the guiding of LV electrode placement, however, further prospective or randomised trials are necessary to verify the utility of BSPM for routine clinical practice.
