Abstract
Objective: To discover the extent of the connection between occlusal plane asymmetry and the rest tone of the four muscle groups of the orofacial region with temporomandibular joint pathology.Methods: Eighty-seven subjects were divided into two groups. The following methods were applied: clinical examination, roentgenological examination, and electromyography. Data were evaluated and statistically analyzed.Results: The variability of occlusal plane inclination in relation to the porion plane was 0-4.6º.The tonus of masseter muscle was higher in the experimental group: 1.45 mV more than in the control group: 1.23 mV (p < 0.05).Conclusion: Asymmetry of the occlusal plane inclination was found for nearly all subjects in both groups. It can be compensated for by adaptation mechanisms and does not cause temporomandibular joint disorders. Undertaken research shows the existence of a proven correlation between TMJ disorders and the resting tonus of the masseter muscle.

[PMID: 38297238 PMCID: PMC10832266 DOI: 10.1186/s12903-024-03892-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2023] [Accepted: 01/12/2024] [Indexed: 02/02/2024] Open
Abstract
OBJECTIVE To study the changes of temporomandibular joints and craniocervical posture in adult patients with bilateral anterior disc displacement, and to explore their correlation, which may provide some clinical value for clinical diagnosis and treatment planning. METHODS Ninety-eight adult patients were divided into 3 groups: 29 patients in bilateral disc normal position group (BN), 33 patients in bilateral Anterior Disc Displacement With Reduction group (ADDWR) and 36 patients in bilateral Anterior Disc Displacement Without Reduction group (ADDWoR). Dolphin and Uceph software were used to measure 14 items of temporomandibular joint and 11 items of craniocervical posture for comparison and correlation analysis between groups. RESULTS There were significant differences in bilateral joint space between three groups. Compared with the BN, the anteroposterior diameter of the condyle was significantly reduced, the condyle was significantly displaced posteriorly and superiorly in the ADDWR and ADDWoR, but the joint fossa width and joint fossa depth did not change significantly. Cervical curvature and inclination were greater in patients with anterior disc displacement than BN, indicating that the craniocervical posture of adult patients with anterior disc displacement was extended and protrusive. CONCLUSION Anterior disc displacement of the temporomandibular joint can displace the condyle upwards and posteriorly and reduce the anteroposterior diameter of condyle, and then make the condyle closer to the wall of articular fossa to induce joint symptoms. Additionally, craniocervical postural position is significantly affected, which may be related to compensate for the effects of airway space.

Abstract
PURPOSE To review and summarize the data on the relationship between craniofacial morphology features and internal derangement (ID) of the temporomandibular joint (TMJ). METHOD A systematic review was designed and registered at PROSPERO, CRD42019132731. The PubMed, Embase and Scopus databases were searched for cephalometric studies comparing craniofacial morphology between female patients with TMJ ID and controls. The Newcastle-Ottawa Scale (NOS) was used for quality assessment. Weighted mean differences for cephalometric measurements were pooled for subsequent meta-analysis. RESULT From the establishment date to August 2020, 14 of 1038 collected records were selected, which consisted of 772 patients with TMJ ID and 423 controls. These records were eventually pooled for the designed statistical analysis after the NOS quality assessment. Compared with the controls, TMJ ID patients had obviously smaller, retruded and clockwise-rotated mandible, showing significantly decreased S-Na, S-Go, Go-Me, Ar-Pog, Ar-Go, SNB, Na perp Pog, and increased FH-MP, SN-MP, PP-MP, SN to Ar-Go, S-Ar-Go and ANB. CONCLUSION Certain craniofacial morphology features were found strongly associated with the presence of TMJ ID, especially the size and position of the mandible.

Arch Oral Biol 2021; 127:105157. [PMID: 34015688 DOI: 10.1016/j.archoralbio.2021.105157] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2021] [Revised: 05/08/2021] [Accepted: 05/10/2021] [Indexed: 11/20/2022]
Abstract
OBJECTIVE To use cone beam computed tomography (CBCT) scans to analyze mandibular symmetry, the occlusal plane and their correlations in patients with high-angle skeletal class III malocclusion and jaw deformity. DESIGN Reconstructed images simulated of CBCT data of 20 adult patients with high-angle skeletal class III malocclusion and jaw asymmetry (Experimental group) and 20 adult patients of skeletal class I with normal faces (Control group) were measured with a three-dimensional (3D) geometric morphological measurement system. Related landmarks, lines and planes were marked and relevant distances and angles of 3D craniofacial structures were measured. The Student t-test was performed to assess symmetry. With the help of the Pearson correlation and Linear regression, we explored the correlations and other relationships among them. RESULTS Compared with control group, the symmetrical differences in experimental group were concentrated in condyle, coracoid process, mandibular angle, mandibular first molar area and the chin (P < 0.05). A strong positive correlation was found between the degree of mandibular deviation and the inclination of the occlusal plane in the coronal position (r = 0.860, P < 0.001) and a linear relationship between them was found: Y = 1.300 + 0.419X (the inclination of occlusal plane was Y, and the mandibular deviation was X). CONCLUSIONS Certain characteristics of mandibular symmetry and the occlusal plane were found in patients with high-angle skeletal class III malocclusion and jaw asymmetry. These findings provide references for doctors to pay attention to the degree and location of mandibular asymmetry and to determine the occlusal plane.

[PMID: 31614226 DOI: 10.1016/j.jormas.2019.10.001] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/04/2019] [Revised: 09/26/2019] [Accepted: 10/03/2019] [Indexed: 10/25/2022]
Abstract
AIM According to the large number of studies, there seems to be a significant relation between hyperdivergence growth pattern and temporomandibular disorders. However, it is not clearly scrutinized which morphological factors can contribute to the development of temporomandibular disorders. The aim of this study was to investigate the relation between some skeletal and facial morphologic features of hyperdivergent facial growth pattern patients and temporomandibular disorders. MATERIALS AND METHODS This case-control study was performed on a population of 50 patients including 25 patients with temporomandibular disorder and 25 non- temporomandibular disorder individuals aged between 15-30 years with hyperdivergent growth pattern (Frankfurt Mandibualr plane angle between 28 and 35 degree). Two groups of symptomatic and asymptomatic patients (case and control) were matched for age and gender. In order to evaluate the skeletal and dental variables, lateral cephalometries was taken and traced after obtaining written consent from the patients. The measured variables were A point to Nasion to B point, Frankfurt plane to Nasion to Pogonion, Nasion to A point to Pogonion, Sella to Gnathion to Frankfurt plan, Articular point to Gonion-Menton, Sella to Articular point to Gonion, Palatal plane to Mandibular plane, and Articular point to Gonion angles. The intervals of Basion to Nasion, Sella to Basion, Gonion to Menton, and amounts of Anterior facial height meas, Upper Anterior facial height ratio to Lower Anterior facial height, posterior facial height, overjet, and overbite Data were analyzed by Chi2 test, t-test, and multivariate test. RESULTS According to the descriptive statistics, the age of the control and case groups averaged 21.12±1.99 and 21.63±1.58 years respectively. Among the people referred to the dental school, the frequency of males and females in the control and case groups were 6, 7 and 19, 18 respectively. The results of t-test and multivariate tests indicated significant differences between the two variables of overbite and mandibular length. CONCLUSION The present study revealed increased overbite (dental feature) and mandibular length (skeletal feature) is more likely to be associated with a higher risk of temporomandibular disorders joint disease in patients with hyperdivergent facial growth pattern. CLINICAL SIGNIFICANCE Treatment of the deep bite condition can be helpful in improving temporomandibular disorder.

Abstract
PURPOSE This patient study was designed to measure the validity of both the horizontal and Camper's planes, which are used as benchmarks to reestablish the sagittal orientation of the occlusal plane angles in dental rehabilitation. MATERIALS AND METHODS Profile digital photographs were made of the first 100 consenting dentate patients as they closed on an occlusal plane analyzer while maintaining natural head posture. Using a digital screen protractor, three angles were measured: the occlusal plane angle relative to the horizontal plane, and the angle between the occlusal plane and Camper's plane from both the superior and inferior borders of the tragus of the ear. RESULTS The angle between the occlusal plane and the horizontal reference plane for the 100 patients ranged from -8.72° to +18.08° (mean +3.25°); the angle between the occlusal plane and Camper's plane, from the superior border of the tragus to the ala of the nose demonstrated a range from -8.49° to +15.16° (mean +3.03°); and the angle between Camper's plane, from the inferior border of the tragus to the ala of the nose and the occlusal plane demonstrated a range from -15.57° to +9.15° (mean -4.09°). CONCLUSIONS Occlusal plane angles measured in this patient population with natural dentitions demonstrated a relatively small mean deviation from both the horizontal plane and Camper's plane when using the superior border of the tragus as the distal reference point, but the range was quite broad and could result in unacceptable occlusal plane angles in many patients undergoing dental rehabilitation. CLINICAL IMPLICATIONS Both Camper's plane and the horizontal reference plane may be acceptable initial reference planes for oral rehabilitation, but additional anatomic and esthetic parameters are required for verification of an esthetically pleasing occlusal plane angle.

Abstract
Objectives This study investigated the association between craniofacial morphology and temporomandibular disorders in adults. The influence of different craniofacial morphologies on painful temporomandibular disorders was also evaluated. Material and Methods A total of 200 subjects were selected, including 100 with temporomandibular disorders (TMD) and 100 without TMD (control), diagnosed by research diagnostic criteria for temporomandibular disorders. All subjects were submitted to lateral cephalometric radiographs, and classified as brachyfacial, mesofacial, or dolichofacial by Ricketts’ analysis. Data were analysed by Tukey-Kramer and Chi-square tests. Results No association between craniofacial morphology and TMD was found (P = 0.6622). However, brachyfacial morphology influences the presence of painful TMD (P = 0.0077). Conclusions Craniofacial morphology is not related to temporomandibular disorders in general.

Abstract
Objective To determine the association between craniofacial structures and the presence of TMD in adolescents. Material and Methods Cases-control study. 46 patients aged 10 to 16 years old were evaluated with their respective lateral cephalometric X-rays (23 cases and 23 controls matched for age and sex). The TTM was evaluated with the research diagnostic criteria for temporomandibular disorders (RDC/TMD). Results The comparison between cases and controls of the craniofacial structures did not show significant differences, however the lower facial height, facial axis and the mandibular plane were slightly higher in the group of cases. In the two-way analysis of ANOVA (diagnosis and age), facial convexity presented differences between the adolescent with and without temporomandibular disorders (p=0,002). Conclusion Craniofacial structures are not associated with the diagnosis of TMD in adolescents. However, changes occur in relation to the former location of the jaw, resulting in a skeletal pattern class II and an elongated shape of the face.

Abstract
INTRODUCTION Temporomandibular disorders (TMD) are the most common non-dental cause of orofacial pain with a multifactorial aetiology. AIM To evaluate the head and craniocervical posture between individuals with and without TMD and its sub types by photographic and radiographic method. MATERIALS AND METHODS Thirty four TMD patients diagnosed according to Research Diagnostic Criteria for TMD's (RDC/TMD) and were divided into 2 groups: Group I (muscle disorder), Group II (disc displacement). Control group comprised of 34 age and sex matched subjects without TMD. Lateral view photographs were taken and the head posture angle was measured. Craniocervical posture was assessed on lateral skull radiograph with two angles (Craniocervical Angle, Cervical Curvature Angle) and two distances (Suboccipital Space, Atlas-Axis Distance). To compare the results, t-test was used with significance level of 0.05. RESULTS Head posture showed no statistical significant difference (p > 0.05) between Group I, II and control group in both photographic and radiographic methods. The cervical curvature angle showed significant difference (p = 0.045) in Group I only. Atlas-Axis Distance was statistically significant in Group II (p = 0.001). CONCLUSION The present study confirmed that there is a negative association of head posture and TMD whereas, cervical lordosis was present in Group I only.

Abstract
BACKGROUND: The association between body postural changes and temporomandibular disorders
(TMD) has been widely discussed in the literature, however, there is little
evidence to support this association. OBJECTIVES: The aim of the present study was to conduct a systematic review to assess the
evidence concerning the association between static body postural misalignment and
TMD. METHOD: A search was conducted in the PubMed/Medline, Embase, Lilacs, Scielo, Cochrane,
and Scopus databases including studies published in English between 1950 and March
2012. Cross-sectional, cohort, case control, and survey studies that assessed body
posture in TMD patients were selected. Two reviewers performed each step
independently. A methodological checklist was used to evaluate the quality of the
selected articles. RESULTS: Twenty studies were analyzed for their methodological quality. Only one study was
classified as a moderate quality study and two were classified as strong quality
studies. Among all studies considered, only 12 included craniocervical postural
assessment, 2 included assessment of craniocervical and shoulder postures,, and 6
included global assessment of body posture. CONCLUSION: There is strong evidence of craniocervical postural changes in myogenous TMD,
moderate evidence of cervical postural misalignment in arthrogenous TMD, and no
evidence of absence of craniocervical postural misalignment in mixed TMD patients
or of global body postural misalignment in patients with TMD. It is important to
note the poor methodological quality of the studies, particularly those regarding
global body postural misalignment in TMD patients.

Abstract
BACKGROUND The contemporary approach of dentistry towards interdisciplinary cooperation is based on the neuromuscular concept. In recent years many authors have pointed out a correlation between orthopaedic and dental findings. Furthermore, there is an intimate biomechanical interrelationship of occlusion with cerebral fluid circulation, left and right equilibrium, gaze stabilisation and headache. The influence of a dental occlusion and temporomandibular joint (TMJ) status on general health has been widely analysed in the current scientific literature. AIM The aim of this analytic study was to display the deep relationship between dentistry and other fields of medicine, and to show the necessity of wide cooperation between dentists and physicians. CONCLUSIONS This study was based on a review of 41 sources, including specialised articles and books. The significance of different anatomical and physiological preconditions (occlusion, muscles and TMJ status) was considered and evaluated separately. However, as a result of modern concepts of general body health, extending cooperation between different fields of medicine is essential. The practical application of the principles of neuromuscular dentistry enables one to increase greatly the treatment efficiency of aches in muscles, headaches, postural dysfunctions as well as of many other diseases. However, the dentist's contribution to the development of an interdisciplinary approach is underestimated. Many theoretical aspects of the interdisciplinary relationship have not been sufficiently examined, hence the practical consequences remain unclear. Further research in the field is urgently needed.

Abstract
INTRODUCTION To establish the skeletal pattern in subjects with malocclusions and temporomandibular disorders (TMD); to assess the relationship between craniofacial skeletal structures and TMD in subjects with malocclusions. MATERIAL AND METHODS Sixty-four subjects with malocclusions, over 18 years of age, were included in the study. Temporomandibular disorders were clinically assessed according to the Helkimo Anamnestic Index. Subjects underwent a lateral cephalogram. Subjects were grouped according to the sagittal skeletal pattern (ANB angle) into class I, II and III. Parametric Student tests with equal or unequal variations were used (variations were previously tested with Levene test). RESULTS Twenty-four patients with TMD (experimental sample); 40 patients without TMD (control group); interincisal angle was higher in class I and II (p < 0.05) experimental subjects; overjet was larger in experimental subjects; midline shift and Wits appraisal were broader in the experimental group in all three classes. In class III subjects, the SNB angle was higher in the experimental group (p = 0.01). Joint noises followed by reduced mandible mobility, muscular pain and temporomandibular joint (TMJ) pain were the most frequent symptoms in subjects with TMD and malocclusions. CONCLUSIONS Temporomandibular joint status is an important factor to consider when planning orthodontic treatment in patients with severe malocclusions; midline shift, large overjet and deep overbite have been associated with signs and symptoms of TMD.
