Oral Rehabilitation of an Osteopetrosis Patient with Osteomyelitis

Osteopetrosis is a congenital disorder characterized by increasing osteoclastic function resulting in osteomyelitis in the jaws. Orofacial findings in osteopetrosis patients are unerupted, malformed, or delayed teeth and many dental caries due to vulnerable enamel and dentin and osteomyelitis. Many reports have described that maxilla is an uncommon site of occurrence for osteomyelitis due to cortical bone morphology and collateral circulation. This report aims to discuss clinical features and prosthodontic management of a patient with clinical features of adult form of osteopetrosis and osteomyelitis in both jaws. The patient has reported better masticatory and speech efficiency with removable dentures in maxillary and mandibular jaw and also self-esteem improvement and family interaction

COMPARATIVE STUDY ON THE EVALUATION OF TEMPOROMANDIBULAR JOINT AND NECK STRUCTURES IN HEALTHY VOLUNTEERS AND IDIOPATHIC SCOLIOSIS PATIENTS

Objective: The aim of this study was to investigate the correlation of temporomandibular joint disorders (TMD) and neck structure changes in adolescents with idiopathic scoliosis (IS) by clinical examination. Material and Methods: The study included 51 patients affected by IS (24 males,27 females; mean age: 13.5± 2.1 years) selected using simple random sampling, and a healthy control group of 50 subjects (23 males, 27 females; mean age: 14.5± 2.3 years). The Diagnostic Criteria for Temporomandibular Disorders: Clinical Protocol and Assessment Instruments (DC/TMD) form was utilized to assess the signs and symptoms of TMD in the subjects. For the evaluation of neck structures,masseter and temporalis muscles, pressure pain threshold (PPT) values were measured with a hand-held pressure algometer.Obtained data were analyzed statistically applying Mann-Whitney U test, Wilcoxon, and chi-squared tests with a significance level of 0.05. Results: According to the DC/TMD form, the following parameters showed statistically significant differences between the groups (p≤0.001): presence of TMD, temporal headache, midline deviation, and right and left lateral movements. The PPT values were higher in the control group compared with the study group (p<0.001). Additionally, the type of pain-related TMD identified in the subjects was myalgia. The myalgia was significantly (p<0.001) higher in the study group (68.6%) than in the control group (22%). Conclusion: This study concluded that spinal diseases which cause postural changes, like IS, in the head and shoulder region are associated with muscle adaptation and alterations in the temporomandibular joint area

Prosthetic Rehabilitation of Cleft Lip Palate with Andrews Bridge Modified as Obturator Prosthesis: Case Report

Background/Aim: Congenital defects such as cleft palate and lips require a long-lasting and multidisciplinary approach. In cases when surgical and orthodontic treatment is not feasible, prosthodontic management of these patients is advocated. Prosthetic rehabilitation of cleft palate in concerning of achieving aesthetic and function (such as swallowing and speech) outcomes is very demanding

In vivo evaluation of occlusalcontact area and maximum bite force in patients with various types of implant-supported prostheses

Objective. To determine the effects of various implant retained and/or supported prostheses on number of occlusal contacts (NOC), occlusal contact area (OCA) and maximum bite force (BF). Patients and methods: In total, 56 patients were included in the study; five test groups and two control groups. The patients in the treatment groups received implant-supported/retained prosthesis; over-dentures retained with two individual attachments in occlusion with complete denture, with four individual attachments in occlusion with complete denture, with four individual attachments in occlusion with fixed partial dentures or natural dentition, 6-implant retained fixed bridges in occlusion with natural dentition and 8-implant retained fixed bridges in occlusion with natural dentition. The patients in control group 1 were wearing conventional complete maxillary and mandibular dentures, whereas in control group 2 they had fixed full-arch porcelain-fused to metal restorations prostheses for both arches. Dental Pre-scale was used measure the NOC, BF and OCA. Results. There was no statistically significant difference between the treatment and control groups, among the groups with regards to NOC. OCA demonstrated different results among the removable and fixed reconstruction groups. With regards to BF, removable dentures supported with four implants showed higher bite force values than controls and two implant over-dentures. Also, a fixed reconstruction using eight implants showed higher BF values than a fixed reconstruction using six implants. Conclusion. Use of implants for removable dentures and fixed reconstructions improve occlusal contact area and bite force

A comparative analysis of the accuracy of different direct impression techniques for multiple implants

Background: The aim of this study was to compare the accuracy of different direct implant impression techniques for edentulous arches with multiple implants. Methods: Five experimental groups (n = 5) were assembled. Experimental models were created by a direct splinted technique (EG2 to EG5) and a non-splinted technique (EG1). In EG2 and EG3 synOcta impression copings were splinted with an acrylic resin bar, and in EG4 and EG5 with a light-curing composite resin bar. In EG3 and EG5 the resin bars were sectioned, while the other experimental groups were not. Three-dimensional discrepancies were measured by a computerized coordinate measuring machine. Distortion values among the groups were analysed using one-way repeated measures ANOVA. The post hoc Tukeys test was then performed for multiple comparisons. Results: The highest accuracy was obtained in EG2 (mean deviation: 12.70 mu m). The acrylic bars demonstrated less deviation (12.70 mu m and 22.71 mu m) from the master model than the light-curing composite resin groups and the non-splinted group (41.09 mu m). The post hoc Tukeys test showed no significant difference among the groups when the effect of splint design on accuracy was investigated. Conclusions: For situations where impressions of multiple implants are to be made, splinting impression copings with acrylic resin demonstrate superior results than the non-splinted technique and splinting with light-curing composite

Comparative Evaluation of the Effects of Implant Position, Impression Material, and Tray Type on Implant Impression Accuracy

Purpose: To evaluate the effect of implant position, impression, and tray material on the accuracy of implant impressions of edentulous arches with multiple implants

Applicability of Zirconia Dental Prostheses for Metal Allergy Patients

The aim of this study was to investigate the applicability of zirconium dioxide (zirconia) as a substitute for metal alloys in a group of metal allergy patients. Fourteen patients (eight women, six men) who had been restored with porcelain-fused-to-metal fixed partial dentures (FPDs) and had exhibited hypersensitivity lesions to dental alloys were enrolled in this study. Patients were previously patch-tested using standard testing substances authorized by the International Contact Dermatitis Research Group. Patients received FPDs with zirconia frameworks and occurrences of oral symptoms were evaluated. No hypersensitivity lesions in the mouth or on the skin were encountered during the follow-up period of 3 years. Zirconia FPDs may be an alternative to porcelain-fused-to-metal FPDs in patients with metal allergies. Int J Prosthodont 2010;23:562-565

Management of Myofascial Pain: Low-Level Laser Therapy Versus Occlusal Splints

The present study was designed to compare the effects of low-level laser with occlusal splints in patients with signs and symptoms of myofascial pain (MP) dysfunction syndrome. A total of 40 (34 women and 6 men, with a mean age of 32.84 [SD, 10.70] years) were selected after the diagnosis of MP according to the Research Diagnostic Criteria for Temporomandibular Disorder. The patients were randomly divided into 2 groups: study group (n = 20) and control group (n = 20). Low-level laser was applied to patients in the study group 2 times per week, for a total of 10 sessions. Patients in the control group were instructed to wear occlusal splints 24 h/d for 3 months. The functional examination was based on Research Diagnostic Criteria for Temporomandibular Disorder and pressure pain threshold values were obtained with the aid of an algometer in both groups. Patients' self-report of pain was evaluated with visual analog scale. Comparisons were made within and between the groups before and after treatment. Vertical movements showed statistically significant improvements after the treatments in both groups (P < 0.01), but when the groups were compared with each other, there were no significant difference between the groups. In both groups, tenderness to palpation of the muscles decreased significantly. Pressure pain threshold evaluations and visual analog scale scores revealed similar results, too. This particular type of low-level laser therapy (820 nm, 3 J/cm(2), 300-mWoutput power) is as effective as occlusal splint in pain release and mandibular movement improvement in MP
