Summary Aim of this study was to introduce a feasible and valid technique for the assessment masticatory performance that is comparable standard sieving method. Twenty‐one chewing samples (Optosil) comminuted by healthy dentate adults were analysed with scanning Scanning performed using conventional flatbed scanner (1200 dpi). All scanned images underwent image analysis (ImageJ), which yielded descriptive parameters such as area, best‐fitting ellipse each particle. Of 2D‐image, volume...

Neuromuscular adaptations during skill acquisition have been extensively investigated for skeletal muscles. Motor rehabilitation is the main target application of motor training. Such measures are also relevant musculature jaw, but few data available adaptation masticatory system. The objective this study was to evaluate and compare long-term training effects different tasks on masseter temporal In 20 healthy subjects, electromyographic response unilateral bilateral maximum voluntary tooth...

Alterations of body sway caused by isometric contractions the jaw muscles have been reported previously. The objective this study was to test if motor tasks masticatory system with different control demands affect posture differently during quiet stance. Position and displacements center foot pressure (COP) were measured for 20 healthy subjects who either kept mandible at rest or performed unilateral bilateral maximum voluntary teeth clenching, feedback-controlled biting submaximum bite...

Introduction: An objective structured clinical examination (OSCE) has been implemented in preclinical dentistry. It was taken at an early stage (propaedeutics course). The objectives of this study were to evaluate the reliability, validity, and feasibility examination, effect circuit number on OSCE score. Methods: designed by expert committee basis pre-reviewed blueprints checklists. Eleven stations formed interdisciplinary circuit. Six groups students (n = 62) passed sequentially round same...

Abstract Objectives The purpose of this study was to investigate the adaptation behavior stomatognathic system after immediate loading (24 72 h surgery) two implants supporting mandibular overdentures, assessed on insertion and three months later. hypothesis that overdentures would significantly change masticatory performance muscle activity at both times. Material methods Thirty subjects (nine female, mean age 69.64 ± 11.81 years; 21 male, 68.67 7.41 years) who participated in a randomized...

To assess the position of temporomandibular joint (TMJ) disc in patients with TMJ pain and compare it equivalent published data asymptomatic volunteers.The oblique coronal closed- open-jaw MR images from 66 were evaluated. Clinical examination followed research diagnostic criteria for disorders. In all images, transverse condylar axis medial lateral edges determined using special software. Inter-rater agreement was calculated [two raters; inter-rater correlation coefficient (ICC)]. The...

Abstract Purpose The study aims to evaluate survival and incidence of complications for pairs implants placed in the front region edentulous mandibles immediately loaded with either bar or L ocator attachments. Materials Methods Forty‐six patients (mean age 69.4 years at inclusion study; 73.9% male) received two interforaminal area symphysis. D older attachments, allocated randomly, were then attached immediately, both clips a framework fastened denture by dental technician within 72 hours....

Objective: The purpose of this study was to compare the short-term effectiveness three different types immediate, non-pharmacological intervention for alleviation painful symptoms temporomandibular disorders (TMD).Material and methods: Thirty-six patients (mean age 41.6 ± 16.7 years, 25 females) diagnosed with non-dysfunctional TMD received counselling subsequently were randomly allocated treatment groups: in Group A prefabricated oral splints water-filled elastic pads (Aqualizer®), those B...

To determine implant survival and success of four conventionally but initially asynchronously loaded implants in implant-supported overdentures for the edentulous maxilla, participants with opposing mandibular two-implant overdentures.Twenty-six received region maxillary canines molars. After healing, 24 these (mean age: 68.3 years) were randomly allocated to one two treatment groups, adapted overdenture was attached unsplinted cylindrical attachments. The other matrixes remained unattached...

Abstract Aim Verification of the interrater reliability axis I diagnoses German version DC/TMD. The hypothesis was that DC/TMD protocol yields comparable results, if examiner instructions are closely followed. Material and Methods A culturally equivalent translation developed. During a 1‐day calibration workshop at University Heidelberg, three examiners were trained by Training Calibration Center. According to guidelines, 16 models (11 cases, five non‐cases) examined four experienced TMD...

Summary Immediate adaptation to experimental‐balancing interferences is known affect jaw kinematics and electromyographic activity ( EMG ). However, little about the influence on masticatory performance parameters. This study hypothesises that balancing‐side significantly reduce of system. Twenty‐one healthy subjects (eleven female, mean age: 24·1 ± 1·2 years) chewed standardised silicone cubes performing 15 cycles right side under three experimental conditions: (i) natural dentition ND ),...

Prosthetic management of thin alveolar ridges in the edentulous mandibles elderly patients, especially time loading, number implants needed, and patient expectations perception, is a challenge implant dentistry.Survival conventionally immediately loaded 2-piece reduced-diameter interforaminal region mandible supporting locator-analog attachments was evaluated. complications peri-implant hygiene were also studied, expectation subjective evaluation treatment documented.Twenty-five patients...

The purpose of this study was to examine, on the basis masticatory performance (MP), total muscle work (TMW), and range movement (RoM), whether reduction profile cusps results in loss biomechanical effectiveness chewing by healthy dentate patients.Twenty patients (10 female, mean age: 24.1 ± 1.2 years) chewed standardized silicone particles, performing 15 cycles. Three experimental conditions were investigated: (1) natural dentition (ND), (2) splints with structured occlusal profiles...

Jaw‐closing movements are basic components of physiological motor actions precisely achieving intercuspation without significant interference. The main purpose this study was to test the hypothesis that, despite an imperfect intercuspal position, precision jaw‐closing fluctuates within range closing indispensable for meeting For 35 healthy subjects, condylar and incisal point positions fast slow jaw‐closing, interrupted at different jaw gaps by use frontal occlusal plateaus, were compared...

Abstract Objectives Removable partial dentures (RPDs) are inserted with the aim to restore masticatory function. There is however inconsistent evidence supporting alleged improvements, posterior occlusal contacts being one of decisive factors. We hypothesized that distribution abutment teeth in RPDs influences performance and functional parameters. To evaluate parameters patients a RPD using single mathematical parameter (tilting index [TI]) for both jaws predicts biomechanical behavior on...

The aim of the current study was to develop an application for mobile devices that can improve organization and documentation clinical teaching in dental schools. app should include a calendar organize treatments, overview all treatments including treatment stages, digital waiting-list teacher’s assessment, standardized recording assessment results. Students members Medical Faculty Computer Science Business Information Systems jointly developed app. Twenty-three students tested usability...

The objective of this study was to investigate the mechanisms physiological control craniomandibular system during force-controlled biting: in intercuspation, restricted by predetermined anatomic-geometrical conditions [i.e. biting intercuspation (BIC)]; and on a hydrostatic auto-balanced static equilibrium mandible (BAL)], which is balanced under unrestricted occlusal conditions. For 20 healthy subjects, spatial positions condyles, lower molars, incisal point were measured,...

Given the context of implementing new licensing regulations for dentistry, this project report describes not only current educational situation regarding communicative and social competency in dental education at Medical Faculty Heidelberg, but also introduces supportive expanded measures that include medical educators clinical staff. Based on less-than-satisfactory skills acquisition students experienced practitioners, it is necesssary to develop competence just university courses with few...
