Background: The esthetic proportion gauge developed by Chu is using a 78% recurring esthetic dental (RED) proportion and it is based on evaluating the size and proportion of frontal teeth chairside. The aim of the present study was to evaluate the validity of Chu’s device and to measure the correlation between the width and length of the frontal teeth, attempting to identify the application of the proportion gauge in Mureș county. Materials and methods: From the 142 selected patients, 73 fulfilled the inclusion criteria. The height and width values of the participants’ teeth were measured with a digital caliper and evaluated with Chu’s esthetic proportion gauge. The measurements were then compared statistically. Results: The values obtained from the digital caliper measurements did not correlate with Chu’s proportion scale, and the results showed no significant differences between the two sides (p >0.05). Conclusions: In conclusion, the measured teeth ratios did not show a similarity with the predetermined esthetic proportion scale suggested by Chu.

Bruxism is a parafunctional activity represented by the gnashing and clenching of one’s teeth. The aim of this study was to determine the utility of screening and monitoring with a Bruxoff device during nocturnal bruxism in 51 children and adolescents (36 with bruxism and 15 without bruxism) by assessing the variations in the intensity and duration of parafunctional activity in each patient. Bruxoff measurements were recorded for at least 60 min for three consecutive nights for each subject. All the parameters recorded using Bruxoff in the control and the study groups showed a statistically significant difference (p < 0.05). The differences found by comparing the values recorded in the male and female study groups are significant for heart rate, the number of masseter muscle contractions during one night, and mixed contractions. The Bruxoff device proved to be important in diagnosing patients with bruxism in our practice.

ObjectivesPre-prosthetic orthodontic treatment is an important part of oral rehabilitation in young adults and requires interdisciplinary planning. This study evaluated the frequency and scope of pre-prosthetic orthodontic interventions (POIs) reported by orthodontic residents and specialists and compared practice patterns between these groups.Material and MethodsA cross-sectional questionnaire study was conducted among 75 orthodontists (42 residents and 33 specialists). Participants reported demographic characteristics and the performance of common POIs. A global intervention score representing the breadth of practice was calculated. Group comparisons were performed using chi-square and Mann-Whitney U tests (P < 0.05).Results Specialists reported significantly higher frequencies of complex interventions, including space management for maxillary lateral incisor agenesis, uprighting tilted teeth, occlusal curve correction, vertical dimension adjustment, deep bite correction, and orthodontic crown lengthening. The global intervention score was significantly higher among specialists than residents [median (IQR): 7.00 (5.00-10.00) vs 4.00 (2.00-8.00); p = 0.001], indicating a broader scope of practice. Most respondents stated that POIs constituted a small proportion of their monthly caseload.ConclusionOrthodontic specialists reported a broader and more complex range of POIs than residents. Clinical experience and interdisciplinary involvement may influence the scope of pre-prosthetic orthodontic practice.

Background: Alterations of the vertical dimension of occlusion may affect masticatory muscle function, which is critical in pre-prosthetic planning, especially in Class II division 2 malocclusions. This study aimed to evaluate the impact of increasing VDO on the myoelectric activity of masticatory muscles using surface electromyography (EMG). The null hypothesis was that a 2–4 mm increase in VDO does not significantly influence muscle activity. Methods: Nine patients with Class II division 2 malocclusion were evaluated. EMG recordings of the masseter and anterior digastric muscles were obtained using the BioEMG II system (BioResearch Asoc., Milwaukee, WI, USA) and Biopak™ software (AcqKnowledge 4.x). VDO was increased using the Dupas universal jig. EMG was recorded for 30 s under six conditions: resting posture, intercuspal position (IM), swallowing, resting posture after VDO increase, IM with increased VDO (IM2), and swallowing with increased VDO (swallowing 2). Results: Most EMG variables showed no statistically significant differences after short-term VDO increase. Significant differences were observed only in the resting activity of both masseter muscles and in the right masseter during maximum intercuspation. No significant changes were identified during swallowing. Conclusions: Within the limitations of this pilot study, a 2–4 mm increase in VDO appears to produce minimal short-term changes in masticatory muscle activity in Class II division 2 patients. These findings should be interpreted with caution due to the small sample size and short observation period, and further studies are required to evaluate long-term neuromuscular adaptation.

Background and Clinical Significance: Severe skeletal Class II malocclusion associated with periodontal compromise and posterior edentulism requires a carefully sequenced interdisciplinary treatment approach integrating orthodontic, surgical, periodontal, and prosthetic rehabilitation. Case Presentation: This case report describes the comprehensive interdisciplinary management of a 21-year-old female patient presenting with skeletal Class II malocclusion, severe mandibular retrognathia, vertical maxillary excess, labial incompetence, temporomandibular joint (TMJ) dysfunction and periodontal deficiencies. The treatment sequence involved occlusal splint therapy, pre-surgical orthodontic decompensation, bimaxillary orthognathic surgery using a segmental Le Fort I osteotomy and bilateral sagittal split osteotomy (BSSO), postoperative orthodontic refinement with aligners, periodontal plastic surgery using the Zucchelli technique and guided bone regeneration (GBR) with implant placement in the posterior mandible. At the four-year follow-up, the patient demonstrated complete root coverage, stable skeletal correction, and satisfactory implant integration, with maintenance of functional and aesthetic outcomes over time. Conclusions: This report highlights the importance of precise preoperative planning and the synergy between orthodontics, orthognathic surgery and periodontics in achieving optimal functional and aesthetic results.
