Filter by:The goal of this clinical trial is to learn about different head position's effect on occlusal contacts during digital interocclusal record. The main question aims to answer is: • Are different head positions in physiological limits can be affected the occlusal contact during interocclusal record? Participants will be asked to stand in three different physiological head positions (neutral, forward and backward) which are common in daily routine. In these positions, after maxillary and mandibular arch scans three different interocclusal records will be taken. Also for assessment of these records in digital occlusal analysis module (oJMA, zebras), three different oJMA record will be taken. Researchers will compare neutral, forward and backward head positions to see if there are any difference in number, density and location of occlusal contacts.
22 Patients having lower completely edentulous mandible aged 55-60 years were selected from the outpatient dental clinic of the Medical Excellence Centre of the National Research (NRC) Cairo, Egypt. Six dental implants were inserted in the mandible of each patient. The patients were randomly categorized into two groups according to the final restoration.
A triple function scan Body were done on healed dental implant, thus simplifying the workflow for full arch cases and reducing the number of visits to only 3 visits. In this technique, scan bodies were utilized for implant position scanning, facial scan alignment and as stoppers for jaw relation capturing as scan bodies were used as stoppers for jaw relation registration.
The aim of the following study was to investigate the existence of a statistically significant correlation between the incisal features (incisal guidance angle, interincisal angle, overbite, overjet), temporomandibular joint (TMJ) morphology and its function. The hypothesis was: I. The protrusive movement of the mandible does correlate with the TMJ anatomy. II. The protrusive movement of the mandible does not correlate with the incisal features. III. The position and relationship of upper and lower permanent incisors do not have a direct and significant effect on the TMJ morphology in young adults.

Occlusal prematurity leading to loss of vertical stopping points between teeth can lead to teeth over eruption creating abnormal contact area which favors food accumulation and plaque retention. All these factors can lead to gingival inflammation and bone loss which may be worsen by abnormal occlusal force. Thus, orthodontic evaluation and treatment with periodontic therapy is mandatory to achieve proper treatment. Aim of the work: To evaluate and compare clinically and radiographically between effect of guided tissue regeneration (GTR) followed by orthodontic intrusion versus orthodontic intrusion followed by GTR in treatment of over erupted tooth with angular bone loss
The temporomandibular joint (TMJ) is closely related to neuromuscular components. A problem occurring in any of these components or parts of the TMJ interferes with the harmonic functioning of the TMJ and invites temporomandibular joint disorders (TMD).Management of TMD can be conservative or surgical. Physiotherapy, local steam application, external muscle massage, occlusal adjustment, analgesic and physiotherapeutic medication and splint treatments are the most frequently recommended conservative treatments. Today, occlusal adjustments are made with the help of a prosthetic or orthodontic appliance. With these intraorally used occlusal splints, a balanced occlusal contact is achieved without applying any force to the mandible in the resting position. Occlusal splints are available in different designs and different construction materials. The stabilization splint, which is one of the most frequently used occlusal splints, and the modified Hawley splint are appliances produced from hard materials. However, some researchers have commented that soft splints produced from resilient materials may also be useful in the distribution of excessive force formed in parafunctional habits. While there are studies stating that hard splints provide more successful results than soft splints in functional problems of the chewing system, there are also studies reporting that they have similar efficacy on muscle pain after short-term use. However, there are no studies in the literature that compare their efficacy in short-term and long-term myalgia patients and demonstrate their efficacy using an objective test such as digital occlusion analysis. There was no study on the effectiveness of different splints on the patient's quality of life. It would be appropriate to carry out our study to fill this gap in the literature.The main purpose of this study is to digitally examine and compare the effects of three different treatment methods (medical therapy, medical therapy+soft splint, medical therapy +hard splint) applied to patients diagnosed with facial myalgia after temporomandibular joint examination on the existing occlusion changes.
The aim of this study is to compare two different methods for occlusal analysis of implant - supported prosthesis (T-scan and conventional method with articulating papers) regarding the stresses transmitted to the implants.
Aim: The aim of this study is to compare the T-Scan digital occlusal analysis system and the occlusal analysis mode of the CEREC Omnicam system, which is mainly used for design/ production, using the data recorded at the centric occlusion position. Material-Method: Occlusal recordings were obtained from healthy 20 females and 20 males aged 18-25 at the centric occlusion position. Records were saved as .jpeg format and transferred to Adobe Photoshop CS6 program. Blue, green, and red colors (shown by the same color codes in both systems) representing light, intense and tight contacts, respectively, were evaluated in terms of the pixel counts. For statistical comparison the differences between the systems Independent Sample T-Test and, between the genders, One Sample T- Test were used (α = 0.05).
evaluation of occlusal force distribution was carried out with the aid of T-Scan device (Tekscan Inc., South Boston, MA, USA) for mandibular complete dentures before and after relining with long term soft liner for controlled type 2 diabetic patients.
