    Abstract Background/Aim. In recent years, bimaxillary surgery has widely been accepted as an effective surgical procedure for the correction of mandibular prognathism. The aim of this study was to determine how bimaxillary surgical correction can change the skeletal dimensions and relations typical of mandibular prognathism and whether the postoperative results can be compared with biometric values of these dimensions in subjects with normal occlusion. Methods. The study included 50 subjects divided into two groups. The analyzed group consisted of 20 patients with mandibular prognathism, mean age 19.8 ± 5.3 years. The control group consisted of 30 subjects with skeletal class I and normal occlusion, mean age 21.5 ± 3.5 years. Cephalometric studies were conducted on 70 lateral cephalograms made on subjects of the analyzed group before and after surgery and in controls. All radio-graphs were transformed into a digital form. Using the computer program "Dr. Ceph", 30 linear and angular skeletal vari-ables were analyzed and compared on each radiograph. The values of examined variables in the analyzed group were compared before and after surgery and with the values of the same variables in the control group. Results. Bimaxillary os-teotomies changed most of the variables that characterize the mandibular prognathism. Changes in the sagittal plane were reflected in a significant increase of angles SNA (by 4° on the average), ANB (6°), and a significant reduction in angles SNB (3°), ArGoMe (8°), NGoMe (6.2°), Bjork’s sum (7°) and the angle of skeletal convexity NAPg (2°). Changes in vertical relationships were reflected in a significant reduction in overall anterior face height N-Me (by 5 mm on average), the lower anterior face height ANS-Me (4 mm), in a significant increase in the total posterior face height S-Go (2.5–3 mm), lower posterior face height PNS-Go (4 mm), in a significant reduction of the basal angle PP/MP (5°) and angle that mandibular plane closes with the anterior cranial base NS/MP (4°). Comparison of ...

    Abstract Bacground/Aim. Recently, maxillary and bimaxillary surgery gained the primacy in the surgical correction of class III deformities. The aim of this investigation was to compare the changes in the skeletal relationships in patients with mandibular prognathism after bimaxillary surgery. Methods. The study included 70 subjects divided into three groups. Twenty class III patients of the experimental group 1 underwent bilateral sagittal ramus osteotomy and twenty patients of the experimental group 2 were subjected to bimaxillary surgery. The control group consisted of 30 subjects with skeletal class I and physiological occlusion. Cephalometric research was conducted on 110 lateral cephalometric radiographs made in subjects of the experimental groups 1 and 2 before and after surgery and in subjects of the control group. Using the computer program “Dr. Ceph”, 30 linear and angular skeletal variables were analyzed on each radiograph. Results. Bimaxillary osteotomies changed most of variables that characterize the mandibular prognathism. The changes in the sagittal plane included the significant increase of sella-nasion to the A point (SNA) angle (by 4º on the average) and the A point to B point (ANB) angle (6°), and significant reduction in angles sellanasion to the B point (SNB) (3º), gonial angle (ArGoMe) (8°), gonial angle inferior (NGoMe) (6.2º), and Björks sum (7°). The vertical relationships were normalized by significant reduction in overall anterior face height N-Me (by 5 mm on the average), the lower anterior face height ANS-Me (4 mm), significant increase in the total posterior face height S-Go (2.5–3 mm), lower posterior face height PNS-Go (4 mm), and significant reduction of the basal and mandibular plane angles. Conclusion. Compared to the isolated mandibular operations, bimaxillary surgery changes more efficiently the sagittal and vertical skeletal relations in patients with class III deformities and harmonizes more successfully the entire skeletal facial profile.

    Abstract Introduction: Osteomyelitis of the jaws is a common disease of the maxillofacial region. The goal of treatment is to alleviate pain, reduce infection, inhibit the progression of the disease and induce bone and mucosal healing. In addition to surgical management and antibiotic and oxygen hyperbaric therapy, new therapeutic strategies for the treatment of osteomyelitis are developed. One of the novel approaches is photobiomodulation therapy or low-level light therapy (LLLT).
    Materials and methods: After surgical treatment, experimental group patients (
    Results: At three and six months, clinical achievement was better in patients treated with LLLT. Pain and discomfort resolution was significantly greater in the experimental group.
    Discussion: Taking into consideration the results of this study, it can be concluded that LLLT shows potential for improving clinical outcome of surgical and medical treatment of secondary chronic osteomyelitis of the jaws. Furthermore, pain and discomfort were significantly reduced in patients treated with LLLT. Further research with a larger sample size is needed to obtain a more accurate insight into this promising field.

    Abstract Introduction. Mandibular prognathism, one of the most severe dentofacial deformities, affects the person’s appearance, psychological health and the quality of life in the most sensitive age period. Objective. The aim of this study was to evaluate the effects of sagittal split ramus osteotomy on the range of mandibular border movements in the early postoperative period. Methods. The study was conducted on 20 patients, of mean age 20.8 years, with mandibular prognathism. All patients included in this study were operated on by bilateral sagittal spliting ramus osteotomy according to Obwegeser and Dal Pont followed by mandibular immobilization during eight weeks. In all patients mandibular border movements were recorded before and six months after surgery using the computerized pantograph Arcus-Digma (KaVo EWL GmbH, Leutkirch, Germany). Results. The analysis of the chosen kinematic parameters revealed that sagittal split ramus osteotomy followed by eight weeks of mandibular immobilization had severe effects on the mouth opening. Six months after surgery the range of maximal mouth opening decreased for approximately 13.9 mm in relation to the preoperative stage. On the contrary, the ranges of maximal protrusion and the border of laterotrusive excursions increased significantly after surgery. Conclusion. In patients with mandibular prognathism where enormous mandibular growth was the main causal factor of the deformity, the sagittal split ramus osteotomy yielded good results. The rigid fixation of bone fragments and reduced period of mandibular immobilization followed by appropriate physical therapy could considerably contribute to a more rapid recovery of mandibular kinematics in the postoperative period.

    Abstract Bacground/Aim. Disturbances of mandibular border movements is considered to be one of the major signs of temporomandibular disorders (TMD). The purpose of this study was to evaluate the possible association between disturbances of mandibular border movements and the presence of symptoms of TMD in the young. Methods. This study included two groups of volunteers between 18 and 26 years of age. The study group included 30 examineers with signs (symptoms) of TMD, and the control group also included 30 persons without any signs (symptoms) of TMD. The presence of TMD was confirmed according to the craniomandibular index (Helkimo). The functional analysis of mandibular movements was performed in each subject using the computer pantograph. Results. The results of this study did not confirm any significant differences between the values of the condylar variables/sagittal condylar inclination, length of the sagital condylar guidance, in the control and in the study group. Conclusion. The study did not confirm significant differences in the length and inclination of the protrusive condylar guidance, as well as in the values of the sagittal condylar inclination between the subjects with the signs and symptoms of TMD and the normal asymptomatic subjects.

    Abstract Disturbances in mandibular kinematics are supposed to be one of the main signs of craniomandibular disorders (CMD). In that regard, recordings of mandibular border movements may offer valuable data in assessing functional efficiency of the OF complex, as well as in diagnosing CM disorders. The electronic pantograph Arcus Digma (Kavo EWL GmBH, Leutkirch, Germany) was used in this study to record and evaluate the trajectories of the interincisal point in three planes during mandibular protrusion laterotrusion and mouth opening. Two groups of volunteers between 18 and 26 years of age were established for this investigation: one consisting of persons with signs (symptoms) of CMD and the other of persons without such signs and symptoms. The results of this study point out the significant differences in the length and shape of interincisal point tracings in the horisontal plane, as well as in angulation of laterotrusive tracings between the examined groups. The reduced mandibular opening was established in 17% of females and 13% of males in the group presenting the signs (symptoms) of CMD.

    Abstract Introduction: Anomalies in growth and development of the craniofacial skeleton, particularly of vertical dysplasia, may be accompanied by distinct signs and symptoms of temporomandibular disorders. Vertical dysplasia followed by numerous occlusal disturbances alters muscular activity resulting in non-physiological strain on articular structures and their remodelling. Objective. The purpose of this study was to evaluate a possible assocciation between certain morphologic features of the craniofacial skeleton and the presence of signs and symptoms of temporomandibular disorders in young adults with preserved natural dentition. Method. The investigation was carried out on 30 lateral cephalometric radiographs made of 30 subjects with signs and symptoms of temporomandibular disorders. According to the values of the ANB angle (Steiner cephalometric analysis), all subjects were classified in the skeletal class 1.The control group consisted of 50 lateral cephalometric radiographs made of subjects with the skeletal class 1 without signs and symptoms of temporomandibular disorders. The roentgencraniometric analysis of lateral cephalometric radiographs included the evaluation of 20 angular dimensions. Results. The result of this study points at significant differences between the Bolton standards and the following angular dimensions in subjects with temoromandibular disorders:(S-Na)-Pg, (B-Na)-Pg, (Pns-Ans)-(Go-Gn), Occl-i, (S-Na)-i, (S-Na)-(Go-Me), (Go-Me)-i, SNB. The comparative analysis between the subjects of the experimental and the control group revealed significant differences in the values of the following angular dimensions: OccP-(Go-Po) i (S-N)-(Go-Me) at the level of p<0.001. Conclusion. The values of the analyzed angular dimensions in both subjects of the experimental and the control group show significant differences when related to the same angular dimensions in the Bolton standards. This can be explained by specific morphologic features of the craniofacial skeleton in subjects of our population. Small ...

    Abstract Introduction. The influence of occlusal condition at the onset of temporomandibular disorders (TMD) has been strongly debated for many years and still is the source of controversy. Up to the eighties in the last century, the occlusal factors such as the presence of uncured malocclusions, discrepancies between intercuspal position and retruded contact position greater than two millimeters, retrusive and nonworking side interferences and loss of posterior teeth were considered to be the primary causes of TMD. Objective. The aim of this study was to estimate the role of occlusal factor in the etiology of craniomandibular dysfunction and therapeutic effects of irreversible occlusal therapy (occlusal equilibration) in patients with TMD. Methods. In the investigation we studied a group of 200 men and women. The average age of the selected patients was between18 and 25 years. The purpose of TMD signs and symptoms was confirmed in every patient using a special functional analysis and evaluating the craniomandibular index (CMI) according to Fricton and Schiffman. The value of craniomandibular index was determined in the group of 15 patients with signs and symptoms of temporomandibular dysfunction. In the study groups occlusal equilibration (selective grinding) was performed according to Okeson using the central position of the mandible as the referent position in the occlusal therapy. The value of CMI was determined before and 30 days after occlusal equilibration. Results. The results of this study confirmed the significant reduction in the signs and symptoms of TMD after occlusal equilibration. The statistical elaboration of the differences between the values of CMI I (before treatment) and CMI II (30 days after treatment) revealed highly significant differences. The CMI I values in the group ranged between 0.076 and 0.346 with the mean value of 0.188±0.082.The values of CMI II ranged between 0.038 and 0.19 with the mean value of 0.038±0.053. Conclusion. The study conformed the validity of irreversible occlusal therapy ...
