Due to the inability to directly apply an intra-oral image with esthetic restoration to restore tooth shape in the computer-aided design system, this paper aims to propose a method that can use two-dimensional contours obtained from the image for the three-dimensional dental mesh model restoration.

First, intra-oral image and smiling image are taken from the patient, then teeth shapes of the images are designed based on esthetic restoration concepts and the pixel coordinates of the teeth’s contours are converted into the vertex coordinates in the three-dimensional space. Second, the dental mesh model is divided into three parts – active part, passive part and fixed part – based on the teeth’s contours of the mesh model. Third, the vertices from the teeth’s contours of the dental model are matched with ones from the intra-oral image and with the help of matching operation, the target coordinates of each vertex in the active part can be calculated. Finally, the Laplacian-based deformation algorithm and mesh smoothing algorithm are performed.

Benefitting from the proposed method, the dental mesh model with esthetic restoration can be quickly obtained based on the intra-oral image that is the result of doctor-patient communication. Experimental results show that the quality of restoration meets clinical needs, and the typical time cost of the method is approximately one second. So the method is both time-saving and user-friendly.

The method provides the possibility to design personalized dental esthetic restoration solutions rapidly.

This study identifies and synthesizes existing literature on the integration of diabetic and dental services and explores a service integration model for optimising diabetic patient health outcomes and improving healthcare systems in low and middle-income countries.

Peer-reviewed literature that analysed the integration of health services regarding dental and medical services were reviewed. The articles were identified using the Academic Search Complete, Business Source Complete, CINAHL Complete, Google Scholar and MEDLINE databases and screened using the PRISMA guidelines.

A total of 40 full-text articles were examined for eligibility out of which 26 were selected for analysis. Diabetes was shown to contribute significantly to the global disease burden and this is also reflected in most low and middle-income countries. It is found that the integration of medical and dental services could help alleviate this burden. Hence, locally adapted Rainbow-Modified Integrated Care model is proposed to fill this integration gap.

The integration of dental and medical services has been proven to be useful in improving diabetic patient outcomes. Hence, the need to facilitate cross-professional collaboration between dentists and physicians cannot be overemphasised and this can be extended and locally adapted by different health systems across the world.

The integration of dental and diabetic services using models such as the Rainbow Model of Integrated Care is recommended to optimise health outcomes of diabetic patients and enhancing service delivery, especially in resource-poor healthcare systems.

This paper aims to automatically obtain the implant parameter from the CBCT images to improve the outcome of implant planning.

This paper proposes automatic simulated dental implant positioning on CBCT images, which can significantly improve the efficiency of implant planning. The authors introduce the fusion point calculation method for the missing tooth's long axis and root axis based on the dental arch line used to obtain the optimal fusion position. In addition, the authors proposed a semi-interactive visualization method of implant parameters that be automatically simulated by the authors' method. If the plan does not meet the doctor's requirements, the final implant plan can be fine-tuned to achieve the optimal effect.

A series of experimental results show that the method proposed in this paper greatly improves the feasibility and accuracy of the implant planning scheme, and the visualization method of planting parameters improves the planning efficiency and the friendliness of system use.

The proposed method can be applied to dental implant planning software to improve the communication efficiency between doctors, patients and technicians.

The article evaluates the obstacles, lessons learned and managerial implications of deploying Lean Six Sigma (LSS) in a dental college hospital in India.

The work adopts the action research (AR) methodology to establish a case study, which is carried out using the LSS define–measure–analyze–improve–control (DAMIC) approach in a dental college. It uses LSS tools to enhance the productivity and performance of the Conservative Dentistry Department of a dental college and to unravel the obstacles and success factors in applying it to the education and healthcare sector together.

The root cause for high turn-around time (TAT) is ascertained using LSS tools and techniques. The effective deployment of the solutions to the root causes of variation assists the dental college to reduce the TAT of the Conservative Dentistry process from an average of 63.9 min–36.5 min (i.e. 42.9% improvement), and the process Standard Deviation (SD) was reduced from 2.63 to 2 min. This, in turn, raises the sigma level from 0.48 to 3.23, a noteworthy successful story for this dental college.

While the results and recommendations of this research are focused on a single case study, it is to be noted that the case study is carried out with new users of LSS tools and techniques, especially with the assistance of interns. This indicates the applicability of LSS in dental colleges; thus, the adopted modality can be further refined to fit India's education and hospital sector together.

This article explains the implementation of LSS from an aspiring user viewpoint to assist dental colleges and policymakers in improving competitiveness. In addition, the medical education sector can introduce an LSS course in the existing programme to leverage the potential of this methodology to bring synergy and collaborative research between data-based thinking and the medical field based on the findings of this study. The most important contribution of this article is the illustration of the design of experiments (DOE) in the dental college process.

Three-dimensional (3D) printing technologies have gained attention in dentistry because of their ability to print objects with complex geometries with high precision and accuracy, as well as the benefits of saving materials and treatment time. This study aims to explain the principles of the main 3D printing technologies used for manufacturing dental prostheses and devices, with details of their manufacturing processes and characteristics. This review presents an overview of available 3D printing technologies and materials for dental prostheses and devices.

This review was targeted to include publications pertaining to the fabrication of dental prostheses and devices by 3D printing technologies between 2012 and 2021. A literature search was carried out using the Web of Science, PubMed, Google Scholar search engines, as well as the use of a manual search.

3D printing technologies have been used for manufacturing dental prostheses and devices using a wide range of materials, including polymers, metals and ceramics. 3D printing technologies have demonstrated promising experimental outcomes for the fabrication of dental prostheses and devices. However, further developments in the materials for fixed dental prostheses are required.

3D printing technologies are effective and commercially available for the manufacturing of polymeric and metallic dental prostheses. Although the printing of dental ceramics and composites for dental prostheses is promising, further improvements are required.

The purpose of this paper is to investigate the service delivery system of a dental clinic in Kazakhstan to maximize the clinic’s efficiency.

The study uses process analysis to determine the capacity utilization and areas of bottlenecks in the dental clinic’s system.

The analysis shows that the most severe bottleneck is identified in step 16 of the 20-step patient flow process. The system efficiency is approximately 62 per cent.

The study will help similar health-care organizations identify areas of bottlenecks in their operational system. This would allow management to deploy optimal resources that would improve systems’ performance.

The paper provides a framework for health-care managers to identify how to reduce patient throughput time and increase patient satisfaction.

It is not an easy and simple task to manufacture a complete denture with high quality. Traditionally, it often needs a medical expert with experience and hand‐on skill, due to the manual way of denture manufacturing. The purpose of this paper is to implement the multi‐manipulator tooth‐arrangement robot system that can fully automate the denture manufacturing process.

A novel complete denture manufacturing mechanism is designed, which is based on the multi‐manipulator and dental arch generator. The visual tooth‐arrangement and robot control software is developed in VC++6.0. Preliminary experiments on tooth‐arrangement have been conducted using the proposed multi‐manipulator tooth‐arrangement robot prototype system.

The multi‐manipulator tooth‐arrangement robot prototype system can automatically design and manufacture a set of complete denture that fit a patient by visual tooth‐arrangement and robot control software according to the patient's jaw arch parameters.

The implication of research is that it is feasible that the manufacture strategy of complete denture fulfilled by multi‐manipulator tooth‐arrangement robot. The limitation of research is that it is difficult to realize coordinate control.

The traditional manual method which makes complete denture by medical personal experience will be changed after the multi‐manipulator tooth‐arrangement robot system is manufactured, and adjustment to each tooth position and orientation will be realized by this system.

A quality assurance programme was introduced to the Community Dentistry Department in 1985 as part of a district‐wide quality assurance initiative. The planning and introduction of the programme are described, as well as the development of appropriate standards and the mechanism of voluntary peer review which have evolved, the amount of time which has been needed to establish these programmes is indicated. Several figures, checklists and tables are presented which may be helpful to managers as a starting point, to enable their staff to consider the issues involved in introducing, implementing and monitoring a quality assurance programme in community dentistry services.

Despite the biological and clinical advances in oral health, dental disease is still a problem for those of low socioeconomic (SE) status, as well as racial and ethnic minorities. In this study, we use the Andersen Behavioral Model of predisposing, enabling, and need factors to examine the effects of race, ethnicity, and income on dental care utilization. Using the Medical Expenditure Panel Survey (MEPS) household component and dental event data (n=8,685), we tested the hypothesis that longer survival or delay in dental care utilization is associated with both minority and lowered SE statuses. Analyses confirm that minority status, income, and education, are predictive of the delay in dental care utilization. This study lends support to the theorized assumption that there are racial and ethnic differences in the pattern of dental care utilization and that these differences as well as other factors contribute to disparity in dental care utilization.

Prisoners’ oral health is an often overseen, yet important aspect of the general health of prisoners. To develop effective measures to improve the situation, it is important to get an overview of existing research. The purpose of this study is to examine and analyse existing research on oral health of prisoners and provide a thorough understanding of prisoners’ oral health and related factors.

Due to relatively few scientific papers on prisoners’ oral health, an integrative review was chosen. Integrative reviews allow for the inclusion of diverse methodologies. A literature search was conducted, followed by an assessment of the quality of the studies by using the Mixed Methods Appraisal Tool. Thematic analysis was used to analyse the studies.

The few studies addressing European prisoners’ oral health in the last 21 years differ in design and methodology. The results from this review indicate that prisoners’ oral health is a complex phenomenon and should be understood from both individual and organisational perspectives. More research is needed to bridge the gap in the literature on prisoners’ oral health.

To the best of the authors’ knowledge, this is the first literature review on European prisoners’ oral health.
