A Technique to Simultaneously Fabricate Multiple Custom Impression Posts for Implantâ Supported Restorations in the Esthetic Zone

Periâ implant transmucosal tissue, an essential element of periâ implant esthetics, is critical to the success of prostheses in the esthetic zone. The optimal transmucosal tissue profile can be transferred to the master cast with the aid of custom impression posts. In this clinical technique, the initial cast used to fabricate provisional prostheses was conveniently used to aid in the timeâ efficient fabrication of multiple custom impression posts simultaneously using selfâ cured acrylic resin. This technique also applies to single restorations. In addition, the use of an initial cast as holder makes it easy to transfer custom impression posts to the mouth accurately and efficiently.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/148416/1/jopr13031.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/148416/2/jopr13031_am.pd

OMS residents’ obstructive sleep apnea-related education, knowledge, and professional behavior: A national survey

ObjectivesOral and maxillofacial surgeons (OMS) treat adult and pediatric patients with obstructive sleep apnea (OSA). Objective 1 assessed sleep apnea–related education, knowledge, and professional behavior of OMS residents in the United States. Objective 2 was to compare the responses of junior versus senior residents and residents in single- versus dual-degree programs.MethodsOMS residents in the United States received a recruitment email with a link to an anonymous online survey; 81 residents responded. The survey included 20 questions to assess respondents’ OSA-related education, knowledge, attitudes, and professional behavior.ResultsRespondents generally agreed that they had received OSA-related didactic-based education (5-point scale with “5” = agree strongly: mean = 3.62) and clinical training (mean = 3.75). Clinical and classroom educational gaps were identified in relation to treatment with oral appliances and hypoglossal nerve stimulation. The residents scored on average 10.38 out of 18 (58%) possible correct answer points for the knowledge questions. Findings about pediatric OSA suggest that only 43.8% of residents understand diagnostic criteria for pediatric OSA, with only 26.6% screening pediatric patients for OSA. A case analysis showed that only 1.5% of residents correctly identified an apnea–hypopnea index of 17 as moderate sleep apnea.Conclusion(s)This survey found knowledge gaps in several areas that can be improved upon. It identifies deficiency in objective knowledge about OSA among OMS residents and a specific lack of clinical training and confidence with hypoglossal nerve stimulation and management of pediatric patients with OSA. Junior and senior residents and single- and dual-degree residents showed no statistically significant differences in any category except senior residents in regard to surgical management of OSA, particularly with maxillomandibular advancement.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/176266/1/jdd13146.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/176266/2/jdd13146_am.pd

Risk factors, diagnosis, and treatment of peri-implantitis: A cross-cultural comparison of U.S. and European periodontists’ considerations

BackgroundPeri-implantitis (PI) is a growing concern in the dental community worldwide. The study aimed to compare U.S. versus European periodontists’ considerations of risk factors, diagnostic criteria, and management of PI.MethodsA total of 393 periodontists from the United States and 100 periodontists from Europe (Germany, Greece, Netherlands) responded to anonymous surveys electronically or by mail.ResultsCompared to U.S. periodontists, European respondents were younger, more likely to be female and placed fewer implants per month (9.12 vs 13.90; P = 0.003). Poor oral hygiene, history of periodontitis, and smoking were considered as very important risk factors by both groups (rated > 4 on 5-point scale). European periodontists rated poor oral hygiene (4.64 vs 4.45; P = 0.005) and history of periodontitis (4.36 vs 4.10; P = 0.006) as more important and implant surface (2.91 vs 3.18; P = 0.023), occlusion (2.80 vs 3.75; P < 0.001) and presence of keratinized tissue (3.27 vs 3.77; P < 0.001) as less important than did U.S. periodontists. Both groups rated clinical probing, radiographic bone loss, and presence of bleeding and suppuration as rather important diagnostic criteria. They rated implant exposure/mucosal recession as relatively less important with U.S. periodontists giving higher importance ratings than European periodontists (3.99 vs 3.54; P = 0.001). Both groups nearly always used patient education, plaque control and mechanical debridement when treating PI. U.S. periodontists were more likely to use antibiotics (3.88 vs 3.07; P < 0.001), lasers (2.11 vs 1.68; P = 0.005), allograft (3.39 vs 2.14; P < 0.001) and regenerative approaches (3.57 vs 2.56; P < 0.001), but less likely to use resective surgery (3.09 vs 3.53; P < 0.001) than European periodontists.ConclusionsU.S. and European periodontists’ considerations concerning risk factors, diagnosis and management of PI were evidence-based. Identified differences between the two groups can inform future educational efforts.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/172247/1/jper10847.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/172247/2/jper10847_am.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/172247/3/jper10847-sup-0001-SuppMat.pd

Comparisons of orthodontic residents- performance and attitudes using 2D, 3D, and virtual reality surgical simulation methods

PurposeAdvances in virtual reality technology for surgical simulation methods may improve diagnosis and treatment planning of complex orthognathic surgery cases. The objectives were to assess orthodontic residents- performance and attitudes when treatment planning orthognathic surgery cases using two- dimensional (2D) digital, three- dimensional (3D) digital, and virtual reality (VR) surgical simulations.MethodsThe study had a mixed methods study design involving 20 graduate orthodontic residents. Their previous experiences, confidence, and competence with orthodontic diagnosis and surgical treatment planning were assessed with a baseline survey. Each resident completed 2D, 3D, and VR treatment planning and simulation tasks in a randomized order and recorded their diagnosis, objectives, treatment plan, and special surgical concerns for each case using a treatment planning worksheet. The worksheets were scored and quantitative data were analyzed. Attitudinal responses to the simulation experience were captured with a post- survey and interview.ResultsThe number of total prescribed surgical movements was greater for 3D and VR simulation methods (p = 0.001). There were no differences in the overall total written treatment plan analysis score among the three surgical simulation tasks. Participants took longer to complete the VR and 3D tasks (p < 0.001) and asked more questions regarding manipulation (p < 0.001) and software features (p < 0.002) for higher fidelity tools. Analysis of qualitative feedback showed positive attitudes toward higher fidelity tools with regard to visualization, manipulation, and enjoyment of the task.ConclusionsThe results demonstrate that simulation methods of increased fidelity (3D and VR) are appropriate alternatives to 2D conventional orthognathic surgical simulation methods when combined with traditional records. Qualitative feedback confirms residents- readiness to adopt VR simulation. However, comprehensive training is needed to increase familiarity and comfort with using the new technology.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/169275/1/jdd12598_am.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/169275/2/jdd12598.pd

Interdisciplinary dental management of patient with oligodontia and maxillary hypoplasia: a case report

Abstract Background The craniofacial developmental abnormality can significantly complicate the oral rehabilitation of patients with oligodontia. This case report describes an interdisciplinary approach that took 7 years to successfully treat a young patient with non-syndromic oligodontia and midface deficiency. Case presentation A 14-year-old patient with complex oral and maxillofacial conditions and diagnosis of oligodontia presented to our clinic. In addition to 4 retained deciduous teeth and congenitally missing 10 permanent teeth, dentofacial findings included maxillary and malar deficiency with a concave facial profile, Angle Class III malocclusion, and poor dental esthetics. The interdisciplinary treatment included pre-surgical orthodontic decompensation, high Le Fort I maxillary osteotomy, postsurgical orthodontic therapy, osseous ridge augmentation using recombinant human bone morphogenetic protein-2 (rhBMP-2), interim removable partial denture, dental implant installation, interim implant prostheses, and final prosthetic rehabilitation. Conclusions The successful treatment of patients with oligodontia and complex dentofacial abnormalities requires the close and orderly collaboration among orthodontist, oral maxillofacial surgeon, and prosthodontist. Within the limitations of this case report, presented interdisciplinary approaches may optimize the oral rehabilitation outcome in patients with similar clinical challenges. A prospective clinical investigation is desired to verify the benefit of presented interdisciplinary approach.http://deepblue.lib.umich.edu/bitstream/2027.42/173471/1/12903_2022_Article_2117.pd
