RESUMO

INTRODUCTION: Clear aligner technology based on a machine learning algorithm is currently available for orthodontic treatment. Treatment planning on the basis of 3-dimensional crown, root, and bone imaging is claimed to provide accurate diagnosis and better treatment outcomes for adult patients with complex needs. This study aimed to answer the following questions: (1) would practitioners modify their original treatment plan once provided with the crown, root, and bone view? and (2) does practitioner satisfaction regarding treatment outcomes change once the crown, root, and bone view is provided? METHODS: An online questionnaire was emailed to members of the American Association of Orthodontists (n = 2300) and the Virginia Orthodontic Education and Research Foundation (n = 211). The survey consisted of videos of 4 patients shown in 2 presentations: crown-only and crown, root, and bone views, generated by artificial intelligence-driven treatment planning software (3D Predict aligner system; 3D Predict, New York, NY). Respondents were asked to answer treatment-related questions and rate the treatment outcomes using a visual analog scale. Statistical analyses were completed to determine the significance of crown, root, and bone view on treatment planning with clear aligners. RESULTS: A total of 70 orthodontists participated in the survey. There were significant differences in responses when viewing patients in crown-only and crown, root, and bone presentations. Across the 4 patients, 33%-43% of practitioners changed their sentiment toward the treatment plan (P <0.001). When rating satisfaction on the 100-point scale, average ratings changed by 10.6 to 21.0 points; both increases and decreases in satisfaction were seen across the patients (P <0.001). CONCLUSIONS: When given 3-dimensional information on the position of a patient's crowns, root, and bone coverage, orthodontists are likely to change their clear aligner treatment plan. This study showed that a confirmation of dehiscence and fenestrations using the root and bone view resulted in practitioner dissatisfaction despite an initial satisfaction with the crown-only view.

RESUMO

INTRODUCTION: This study aimed to assess the perceived efficacy of aligners (Invisalign; Align Technology, Santa Clara, Calif) at performing extrusive movements of maxillary lateral incisors and to evaluate and compare differences in treatment planning protocols and other interventions used when required between orthodontists and general dentists with various degrees of experience. METHODS: An original 18-question survey was sent by mail to a randomized and geographically proportionate selection of orthodontic specialists (N = 400) and general dentists (N = 400) listed as providers on the Invisalign Web site. The data were analyzed using analysis of variance and chi-square tests. RESULTS: One hundred twenty-six providers responded to the survey (15.8% response rate), including 36 general dentists and 90 orthodontists. Overall, the average perceived efficacy was 4.71 out of 10 (95% confidence interval, 4.28-5.14). The threshold for identification of tracking issues was significantly associated with provider type (P = 0.0305). General dentists were significantly more likely to prefer an optimized attachment (P = 0.0001), whereas orthodontists were significantly more likely to prefer a gingivally-beveled horizontal rectangular attachment (P <0.0001). A refinement scan was the most common intervention method, followed by the bootstrap technique. CONCLUSIONS: The average perceived efficacy for extruding maxillary lateral incisors with aligners was 4.71 out of 10. Orthodontists had a lower tolerance than general dentists for tracking issues. A refinement scan was the most common method of intervention. General dentists and orthodontists differed in their treatment planning preferences and timing of intervention.

RESUMO

INTRODUCTION: Teledentistry in orthodontics is growing, yet patient preferences for its use is unknown. This study aimed to determine the perceived value of doctor-to-patient face-to-face interaction, convenience, and attitudes toward specific uses of teledentistry among orthodontic patients. METHODS: Private practice orthodontists emailed an electronic survey to active patients. Patients aged ≥18 years completed the survey regarding their treatment. Parents of patients aged <18 years completed a separate survey regarding their child's treatment. Responses were compared on the basis of patient characteristics (adult vs child, braces vs clear aligners, etc). RESULTS: Three hundred and seventy-seven respondents from 8 orthodontic practices participated in the survey. Eighty-five percent of parents considered face-to-face interaction important, and 85% said that their child's treatment fit conveniently into their schedule. Adult responses were 86% and 89%, respectively. Adult preference for face-to-face was significantly higher than parents of adolescent patients (83% vs 78%; P = 0.038). Adults treated with clear aligners were less likely to strongly agree that their treatment fitted conveniently in their schedule (51% vs 76% in braces; P = 0.0490) and were more likely to be interested in using teledentistry (27% vs 18% in braces; P = 0.0429). CONCLUSIONS: Most orthodontic patients prefer to be seen face-to-face. This is due to the high value placed on face-to-face interaction with the orthodontist. Most patients do not consider their treatment inconvenient. Patients prefer that teledentistry be used to enhance communication as opposed to replacing face-to-face interaction. Implementing teledentistry in orthodontics should be applied on a patient-to-patient basis with continued emphasis on the doctor-patient relationship.

RESUMO

INTRODUCTION: This study aimed to determine adaptations orthodontists made during the coronavirus disease 2019 pandemic to maintain safety and determine which adaptations will remain after the pandemic. METHODS: An original 34-question survey was sent by mail to a randomized selection of practicing orthodontic specialists (n = 1000). Questions included the changes made during the pandemic in 4 categories (infection control, social distancing, appliance type, and teleorthodontics) and whether those changes will remain postpandemic. RESULTS: The use of personal protective equipment increased during the pandemic, with a significant decrease anticipated after the pandemic. The most common aerosol modification during the pandemic and predicted after the pandemic was using an assistant with high-volume suction (61% and 49%, respectively; P = 0.0013). Ninety-six percent of orthodontists changed their waiting room protocol during the pandemic, but only 23% plan to continue that practice (P <0.0001). Forty-two percent of orthodontists increased clear aligners during the pandemic in response to patient demand (91%). The use of teleorthodontics increased from 8% to 68% during the pandemic and is expected to decrease significantly postpandemic. Virtual appointments are anticipated to be used for screening and consultations of new patients and monitoring active patients in clear aligners but not fixed appliances. CONCLUSIONS: The specialty recommended patient safety modifications during the coronavirus disease 2019 pandemic. Postpandemic, enhanced personal protective equipment is expected to decrease, and high-volume suction will likely be continued for aerosol-producing procedures. Teleorthodontics will likely remain in limited use.

RESUMO

INTRODUCTION: This study evaluated current trends and perspectives among orthodontists regarding clear aligner therapy in the mixed dentition (CAMD), including insights into perceived indications, compliance, oral hygiene, and other factors. METHODS: An original, 22-item survey was mailed to a randomized, nationally representative sample of practicing orthodontists (n = 800) and a specific, randomized subsample of high-aligner-prescribing orthodontists (n = 200). Questions assessed respondents' demographic information, experience with clear aligner therapy, and perceived advantages and disadvantages of CAMD compared with fixed appliances (FAs). Responses were compared using McNemar's chi-square and paired t tests to assess CAMD vs FAs. RESULTS: One thousand orthodontists were surveyed, and 181 (18.1%) responded over 12 weeks. CAMD use was less common than mixed dentition FAs, but most respondents predicted an increase in their future CAMD use (57.9%). Among respondents using CAMD, the number of patients with mixed dentition treated with clear aligners was significantly lower than the number of total patients with clear aligners (23.7% vs 43.8%; P <0.0001). Fewer respondents considered skeletal expansion, growth modification, sagittal correction, and habit cessation feasible indications for CAMD compared with FAs (P <0.0001). Perceived compliance was similar for CAMD and FAs (P = 0.5841), but perceived oral hygiene was significantly better with CAMD (P <0.0001). CONCLUSIONS: CAMD is an increasingly common treatment modality for children. Most surveyed orthodontists reported limited indications for CAMD compared with FAs but perceived noticeable benefits for oral hygiene with CAMD.

RESUMO

INTRODUCTION: Extrusion of maxillary lateral incisors during aligner treatment is a difficult movement to achieve accurately. Despite recommendations regarding attachment design, few studies and no prospective trials compare predictability among attachments. This study aimed to compare the efficacy between optimized and horizontal attachment designs for achieving maxillary lateral incisor extrusion during clear aligner treatment. METHODS: The study included maxillary lateral incisors in 3 orthodontic practices requiring at least 0.3 mm of extrusion during the first series of 20-25 aligners in patients aged ≥16 years who were scheduled to begin clear aligner treatment (Invisalign; Align Technology, San Jose, Calif). Teeth were randomly assigned to receive optimized (O), rectangular horizontal nonbeveled (H), rectangular horizontal incisally-beveled (HIB), or rectangular horizontal gingivally-beveled (HGB) attachments. After the first series, a blinded evaluator measured extrusion using superimpositions with initial and predicted models. Linear models determined the difference in the predicted extrusion percentage achieved on the basis of attachment design. Other covariates were patient age, sex, number of trays, and self-reported compliance. RESULTS: Forty patients (74 teeth) were enrolled, and 38 patients (71 teeth) completed the study. Intraexaminer and interexaminer reliability for extrusion measurements was high (intraclass correlation coefficient, 0.985 and 0.991, respectively). The achieved extrusion was significantly less than predicted (mean, 73%; P <0.0001). The average achieved extrusion was 62%, 79%, 78%, and 78% for O, H, HIB, and HGB attachments, respectively, with H significantly more effective than O (P = 0.0403). Horizontal attachments (H, HIB, and HGB combined) were significantly more effective than O attachments (P = 0.0060), with an average difference in achieved extrusion of 14% of the predicted amount (95% confidence interval, 4-23; estimated 76% vs 62%). Horizontal attachments were an estimated 22% more effective than O attachments for extruding maxillary lateral incisors. CONCLUSIONS: Horizontal attachments are more effective than O attachments for predicted maxillary lateral incisor extrusion between 0.3 and 2.5 mm. The 3 horizontal attachment designs evaluated performed similarly for achieving predicted extrusion. TRIAL REGISTRATION: This randomized clinical trial was registered and reported at clinicaltrials.gov (NCT04968353). PROTOCOL: The protocol was not published before trial commencement. FUNDING: This study was funded in part by the Alexander Fellowship of the Virginia Commonwealth University School of Dentistry, the Southern Association of Orthodontists, and the Virginia Orthodontic Education and Research Foundation. No funding source influenced the study design, the collection, analysis or interpretation of data, writing of the report, or the decision to submit the article for publication.

RESUMO

INTRODUCTION: The aims of this study were to (1) investigate and compare the educational value of the most popular YouTube (www.youtube.com; Google, San Bruno, Calif) orthodontic patient testimonials between braces, in-office aligners (IOA), and direct-to-consumer aligners (DTCA), and (2) classify the emotional response of the viewers through sentiment analysis of the video comments. METHODS: Three different phrases relevant to braces, IOA, and DTCA were searched on YouTube. The 20 most popular patient testimonial videos meeting the criteria for each group were selected for a total of 60 videos. Using the YouTube application program interface for each video, 13 video metrics were extracted. An information completeness score was assigned, and the video comments were analyzed using sentiment analysis software. RESULTS: The 60 videos included were viewed 34.4 million times by internet users. Braces videos had significantly more likes, comments, and a higher viewer interaction score than the IOA and DTCA videos. IOA videos had a higher median information completeness score than braces and DTCA videos. Of the 5149 video comments with polarity, 53.6% were positive, and 46.4% were negative (P <0.0001). There was no significant association between the treatment modality and positive or negative comments (P = 0.5679). CONCLUSIONS: There is high user engagement on YouTube with orthodontic patient testimonials. YouTube users interact with braces patient testimonials the most. YouTube viewers' comments on orthodontic patient testimonials express more positive sentiment than negative sentiment. There was no significant difference in positive and negative sentiment between the video comments for the 3 different treatment modalities.

RESUMO

INTRODUCTION: This study aimed to evaluate the factors that influence potential orthodontic patients choosing an orthodontist, general dentist, or direct-to-consumer (DTC) aligners for their treatment, and to determine the level of interest in each provider type. METHODS: An electronic survey was administered to 249 adults among the general population in the United States to determine and evaluate the level of interest in pursuing orthodontic treatment with each provider type. RESULTS: When asked their preference for provider type, 44% of respondents selected orthodontist, 34% selected DTC aligners, and 22% selected general dentist. Among respondents with the highest level of interest in pursuing orthodontic treatment, 50% selected orthodontist, and 27% selected DTC aligners (P = 0.002). For respondents with a moderate interest in pursuing treatment, only 21% selected orthodontist, and 48% selected DTC aligners (P = 0.002). The biggest perceived advantage of treatment with orthodontists was the quality of treatment, and for DTC aligners, it was convenience, followed by cost. Among adults with children, 34% selected DTC aligners for themselves, and only 16% selected DTC aligners when selecting for their children (P = 0.0001). CONCLUSIONS: There is a high level of interest among adults in pursuing treatment with both orthodontists and DTC aligners. Patients with the highest level of interest in pursuing orthodontic care tend to prefer orthodontists, whereas those with a moderate interest in pursuing treatment prefer DTC aligners. Patients tend to select orthodontists primarily because of treatment quality, whereas they select DTC aligners for convenience and then cost. Parents tend to select an orthodontist for their child's treatment, even when selecting DTC aligners for themselves.

RESUMO

INTRODUCTION: Patients and parents want shorter treatment times, but it is unclear whether they would compromise outcome quality to shorten treatment. The purpose of this study was to compare orthodontists' and parents' perceptions of finished occlusion and their willingness to extend treatment time to achieve improved outcomes. The effects of elapsed treatment time and patient compliance were also investigated. METHODS: Parallel surveys for orthodontists (n = 1000) and parents (n = 750) displayed simulated treatment outcomes of well-aligned teeth with occlusions in 1 mm increments from 3 mm Class III to 3 mm Class II. Participants rated their preferences on a visual analogue scale (VAS; 0-100) and specified whether they would extend treatment, and for how long, to improve the occlusion. RESULTS: Two hundred thirty-three orthodontists (23%) and 243 parents (32%) responded. Despite differences between the scores given (P < 0.0001), both groups rated Class I occlusion most acceptable (mean VAS = 93.9 and 80.7, respectively) and 3 mm Class III malocclusion least acceptable (mean VAS = 25.9 and 40.9, respectively). Parents were willing to extend treatment more often and for a greater time than orthodontists to improve results (P < 0.0001). In addition, parents were less willing to terminate treatment early (P < 0.05). Both groups perceived existing outcomes as more acceptable if the patient was noncompliant (P < 0.05), but elapsed time in treatment had no significant effect on ratings. CONCLUSIONS: For outcomes with well-aligned teeth, orthodontists and parents agreed on what the most and least acceptable occlusal relationships were. To achieve better outcomes, parents were willing to extend treatment duration more often and for a greater time than were orthodontists. In addition, parents were less willing than orthodontists to terminate treatment early.

RESUMO

INTRODUCTION: The purpose of this study was to evaluate the ability of a publicly available facial recognition application program interface to calculate similarity scores for presurgical and postsurgical photographs of patients who underwent orthognathic surgeries. Our primary objective was to identify which surgical procedure(s) had the greatest effect(s) on the similarity score. METHODS: Existing photographs for 25 orthodontic-orthognathic patients were analyzed using the application program interface to calculate similarity scores between the presurgical and postsurgical photographs. Photographs from 2 presurgical timepoints were compared as controls. Both relaxed and smiling photographs were included to assess the added impact of a facial pose. Patient characteristics and surgery types were recorded for statistical analysis. Nonparametric Kruskal-Wallis rank-sum tests were performed to analyze the relationship between patient characteristics and similarity scores. Multiple comparisons Wilcoxon rank-sum tests were performed on the statistically significant characteristics. RESULTS: Recognition scores were significantly lower after orthognathic surgery at rest (P = 0.009) and smiling (P <0.001). Patients receiving both LeFort I and bilateral sagittal split osteotomy (BSSO) surgeries had a lower median similarity score compared with those that received only BSSO (P = 0.009) when comparing relaxed photographs before and after surgery. Similarly, for the score comparing presurgical relaxed photographs to postsurgical smiling photographs, patients that received both surgeries were found to have lower similarity scores compared with those receiving only BSSO (P = 0.036). CONCLUSIONS: Two-jaw surgeries were associated with a statistically significant decrease in similarity score when compared with 1-jaw procedure. Pose was also found to be a factor influencing similarity scores, especially when comparing presurgical relaxed photographs to postsurgical smiling photographs.

RESUMO

INTRODUCTION: The aims of this study were to investigate the eruption pattern of maxillary permanent canines in the alveolar cleft area after secondary alveolar bone grafting and to assess the risk indicators for canine impaction. METHODS: The sample consisted of 75 patients with unilateral cleft lip and palate who underwent secondary alveolar bone grafting with rhBMP-2 with a mean age of 9.8 years of age at 1 center. A split-mouth study design was used, with the noncleft hemiarch comprising the control group. Panoramic radiographs taken before, immediately after, and 1 year after secondary alveolar bone grafting were used to assess the following parameters in both cleft side (CS) and noncleft side: canine mesiodistal angulation, canine height relative to the occlusal plane, canine mesial displacement, and superimposition with the neighboring maxillary incisors. The frequency of associated dental anomalies was compared between patients with and without CS canine impaction. Data were evaluated using analysis of variance, t tests, Fisher tests, and multiple logistic regression analysis (P <0.05). RESULTS: On the CS, maxillary canines were usually more mesially angulated and more distant from the occlusal plane compared with the noncleft side. The prevalences of canine impaction on the CS and noncleft side were 24% and 1.3%, respectively. Maxillary impacted canines on the CS demonstrated increased mesiodistal angulation and height at all time points. No association between CS canine impaction and mesial displacement (sectors) was found. An increased prevalence of lateral incisor agenesis on the CS was observed in the subgroup with canine impaction. CONCLUSIONS: Increased mesial angulation and lateral incisor agenesis on the CS are early risk indicators for maxillary canine impaction in patients with unilateral cleft lip and palate.

RESUMO

Digital dental technology is increasingly becoming an integral part of the modern orthodontic practice. The accuracy of digitally articulated models is critical when developing orthodontic treatment plans. OBJECTIVE: to determine the accuracy of model articulation generated by extraoral and intraoral scanners. DESIGN: One extraoral scanner with a wax (EOW) or vinyl polysiloxane bite registration (EOVPS), and three intraoral digital scanners utilizing confocal static (IOCS), confocal continuous (IOCC), and blue LED light technologies (IOLED) were used. METHODS: On each scanned image (n = 25 per group), measurements between the maxillary and mandibular molars and canines were performed and then compared to the gold standard values. A deviation of ± 0.5 mm from the gold standard value was considered acceptable. The significance level was kept at 0.05. RESULTS: IOCS and IOCC were accurate for all six interarch measurements. IOLED and EOVPS groups produced the next most accurate articulation of the digital models. EOW group resulted in the least accurate articulation. Also, of the software platforms used, the OrthoCAD™ was found to be the most accurate system for making measurements on digital casts. CONCLUSIONS: Only the scanners with the confocal imaging technology produced accurately articulated models. Differences between the scanners may be related to measurement errors inherent to the technologies employed and the software systems used to process the images.

RESUMO

INTRODUCTION: A new, highly filled primer is currently marketed as a fluoride delivery system effective in reducing white spot lesions in orthodontic patients. However, no studies in the literature support this claim. The purpose of this in-vivo study was to investigate the retention and the efficacy of this primer in reducing the formation of white spot lesions. METHODS: In each patient for whom premolar extractions were planned (n = 22), 1 premolar was randomly chosen as the experimental tooth for the application of the fluoride delivery system (Opal Seal; Ultradent Products, South Jordan, Utah), and the contralateral tooth was assigned as the control to receive the standard treatment (Transbond XT; 3M Unitek, Monrovia, Calif). After the bonding procedures, separators were placed around the premolar brackets to encourage plaque retention over 8 weeks. After the extractions, the tooth surfaces were evaluated visually and with microhardness techniques for demineralization. Primer retention was also investigated. RESULTS: There were no statistically significant differences in the numbers of white spot lesions between the 2 groups. The primer retention was calculated as 50%. CONCLUSIONS: The results indicated no significant difference between the efficacies of the fluoride-releasing primer and the control primer in reducing demineralization over the duration of the study.

RESUMO

The aim of this study was to determine the influence of age and gender on the incidence of calcification in laryngeal cartilage diagnosed on lateral cephalometric radiographs routinely taken for orthodontic diagnosis. The lateral cephalometric radiographs of 957 patients who met the study criteria were analyzed from among the 1000 lateral radiographs originally collected. The images were evaluated independently by two investigators. Given the dichotomous dependent variable (calcification or no calcification), a mixed logistic regression model was used to test how age and gender affected calcification. The effect of age and gender reliably determined the likelihood of laryngeal cartilage calcification. The greatest differences in the degree of calcification by gender were found at ages 20-25 years. The degree of calcification increased with age, reaching 100% in women at age 30 and in men at age 50. In women, the degree of calcification was higher than in men from the age of 13 years and levelled off at the age of 50 years. The interrater agreement was strong k = 0.97, z = 30.0, p < .001. Calcification can be detected by orthodontists trained in lateral cephalogram analysis and can be used as a screening or diagnostic tool to detect calcified areas in the larynx.

RESUMO

INTRODUCTION: Despite the many advances to improve the practice of orthodontics, white spot lesions, or decalcifications, remain a common complication in patients with poor oral hygiene. The purpose of this study was to assess the perceptions and level of awareness of patients, parents, orthodontists, and general dentists toward the development of white spot lesions during orthodontic treatment. METHODS: This was a prospective epidemiologic survey of the perceptions of orthodontic patients (n = 315), parents (n = 279), orthodontists (n = 305), and general dentists (n = 191) regarding the significance, prevention, and treatment of white spot lesions. RESULTS: All surveyed groups indicated that white spot lesions detracted from the overall appearance of straight teeth, attributed primary responsibility for the prevention of white spot lesions to the patients themselves, and thought that the general dentist should be responsible for treating white spot lesions. Patients regarded themselves as ultimately responsible for the prevention of white spot lesions (P <0.05). CONCLUSIONS: The patients, parents, orthodontists, and general dentists had similar perceptions regarding the significance, prevention, and treatment of white spot lesions. All groups indicated that patients were the most responsible for the prevention of white spot lesions. Communication among patients, parents, orthodontists, and general dentists needs to improve to decrease the incidence of white spot lesions in the orthodontic population.

RESUMO

OBJECTIVES: To determine recognition ability and the levels of esthetic tolerance of deep bite and anterior open bite (AOB) among laypeople and investigate the factors affecting levels of tolerance. MATERIALS AND METHODS: Using a questionnaire, laypeople (N = 100) were examined, and overbite was measured. They were tested for whether they recognized deep bite and AOB. Esthetic tolerance thresholds for deep bite and AOB were selected by incremental depiction in grayscale images. Stepwise logistic regression analyses were used to quantify the effect of recognition and other factors (age, sex, education level, occupation, history of orthodontic treatment, interest in orthodontic treatment or retreatment, and overbite presence) affecting the tolerance of overbite problems (α = 0.05). RESULTS: Of the participants, 55% and 94% recognized deep bite and AOB, respectively. Participants with a deep bite were significantly more likely to esthetically tolerate deep bite compared with those without a deep bite (odds ratio [OR], 3.57; 95% confidence interval [CI], 1.29-9.89). Participants who recognized a deep bite problem had significantly lower esthetic tolerance to deep bite compared with participants who did not recognize a deep bite (OR, 0.17; 95% CI, 0.06-0.45). None of the other eight chosen factors significantly affected the tolerance level of AOB (P > .05). CONCLUSIONS: Participants with a deep bite or those who did not recognize a deep bite had significantly higher esthetic tolerance of deep bite than those without or those who recognized the problem (P < .05).

RESUMO

Aligners are an example of how advances in dentistry can develop from innovative combinations of 3D technologies in imaging, planning and printing to provide new treatment modalities. With increasing demand for esthetic orthodontic treatment, aligners have grown in popularity because they are esthetically more pleasing and less obstructive to oral hygiene and other oral functions compared to fixed orthodontic appliances. To observe and estimate aligner treatment interest among Google Search users, Google Trends data were obtained and analyzed for the search term, "Invisalign". A prediction of interest for the year 2022 for three European Union countries with the highest GDP was developed. "Invisalign" was chosen to represent all orthodontic aligners as the most searched term in Google Trends for aligners. This is the first study to predict interest in the query "Invisalign" in a Google search engine. The Prophet algorithm, which depends on advanced statistical analysis methods, positions itself as an automatic prediction procedure and was used to predict Google Trends data. Seasonality modeling was based on the standard Fourier series to provide a flexible model of periodic effects. The results predict an increase in "Invisalign" in Google Trends queries in the coming year, increasing by around 6%, 9% and 13% by the end of 2022 compared to 2021 for France, Italy and Germany, respectively. Forecasting allows practitioners to plan for growing demand for particular treatments, consider taking continuing education, specifically, aligner certification courses, or introduce modern scanning technology into offices. The oral health community can use similar prediction tools and methods to remain alert to future changes in patient demand to improve the responses of professional organizations as a whole, work more effectively with governments if needed, and provide better coordination of care for patients.
