Purpose: The aim of this study was to examine and compare the mechanical success of customized computer aided design and manufacturing (CAD-CAM) and prefabricated abutments and screws before and after cyclic loading, through measuring removal torque values.

Materials And Methods: The study was performed in accordance with ISO 14801:2016 standarts. Twenty eight dental implants with identical charecteristics were divided into two equal groups.

Investigation of Conventional vs Nonoriginal CAD/CAM Bars with Production Stage Differences: An In Vitro Precision Study Using a Novel Technique.

Purpose: The aim of this study was to evaluate the precision of fit of bar frameworks fabricated using three different production processes and the effect of changes in the CAD/CAM process steps on the precision of the resulting bar frameworks.

Materials And Methods: Four implants were applied to a mandibular phantom model, and three different production techniques were used to fabricate 30 bar frameworks. In the first group, the bar frameworks were fabricated with the conventional production process (the lost-wax technique; n = 10).

Variations in concerns reported on the patient concerns inventory in patients with head and neck cancer from different health settings across the world.

Background: The aim was to collate and contrast patient concerns from a range of different head and neck cancer follow-up clinics around the world. Also, we sought to explore the relationship, if any, between responses to the patient concerns inventory (PCI) and overall quality of life (QOL).

Methods: Nineteen units participated with intention of including 100 patients per site as close to a consecutive series as possible in order to minimize selection bias.

In vitro study of effects of aging and processing conditions on colour change in maxillofacial silicone elastomers.

Background: The inherent colour change in maxillofacial silicone elastomers becomes perceptible 6-12 months after fabrication. Determining the factors that accelerate the degradation of the prosthesis can help the clinicians increase its life span. Therefore, the aim of the study was to investigate the effect of time passage, processing temperature, and molding-stone colour on the colour change of maxillofacial silicone elastomers after darkroom storage for 6000 h.

Comparisons of measures that evaluate oral and general health quality of life in patients with temporomandibular disorder and chronic pain.

: To analyze the oral and general health related quality of life (HRQOL) measures, and to establish their ability to categorize chronic temporomandibular disorders (TMD).: Data were collected from 104 patients through a questionnaire with detailed socio-demographic information, the Oral Health Impact Profile (OHIP-14), the Short-Form-36 (SF-36), the Revised Symptom Checklist-90-R (SCL-90-R), and the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) Axis I and II. Descriptive statistics were computed.

Predictors of obturator functioning and satisfaction in Turkish patients using an obturator prosthesis after maxillectomy.

Objective: The aim of this study was to determine the sociodemographic, behavioral, and clinical factors affecting obturator function and satisfaction using the obturator functioning scale (OFS) in maxillectomy patients rehabilitated with obturator prostheses.

Study Design: The study sample consisted of 41 maxillectomy patients. The OFS was translated into Turkish and adapted for assessing obturator functioning and patient satisfaction among Turkish patients.

Effect of vulcanization temperature and dental stone colour on colour degradation of maxillofacial silicone elastomers.

Background: Colour degradation is a major problem in maxillofacial silicone elastomers. Recent studies have focused on colour stability and the mechanical properties of the silicone elastomers. A colour match is also essential for the acceptance of the prosthesis by the patient.

Early results of low-level laser application for masticatory muscle pain: a double-blind randomized clinical study.

Background: To evaluate the effect of Low Level Laser (LLL) application at the points of greatest pain in patients with chronic masticatory muscle pain.

Methods: A total number of 30 (21 women, 9 men, with a mean age of 39.2) were selected after the diagnosis of MPDS according to the Research Diagnostic Criteria for Temporomandibular Disorder (RDC/TMD).

A surface roughening technique for maxillofacial prostheses.

Giving a natural surface texture to the maxillofacial prostheses is one of the major goals for the maxillofacial prosthodontists. This article describes a technique for application of an antiskid epoxy resin to the surface of the definitive mold before pouring the maxillofacial silicone elastomer. This technique produces evenly distributed and same-size pores that are more similar to the natural appearance of human skin.

Validation of the Turkish version of the Liverpool Oral Rehabilitation Questionnaire version 3 (LORQv3) in prosthetically rehabilitated patients with head and neck cancer.

Background: The Liverpool Oral Rehabilitation Questionnaire version 3 (LORQv3) is a measure assessing the impact of oral rehabilitation on patients' health-related quality of life (HRQOL).The aims of the study were to adapt culturally the LORQv3 for Turkish-speaking head and neck cancer patients who had undergone prosthetic rehabilitation and to undertake an initial investigation of its psychometric properties.

Methods: The Turkish version of the LORQv3 was translated and culturally adapted into Turkish, and tested on a sample of 46 head and neck cancer patients who had undergone prosthetic rehabilitation at a university clinic.

Soft Tissue Response and Survival of Extraoral Implants: A Long-Term Follow-up.

Maxillofacial defects may be reconstructed by plastic surgery or treated by prosthetic mean rehabilitation. In case of large defects, prosthetic rehabilitation rather than surgical reconstruction is preferred due to the insufficient esthetic results of surgical interventions. However, retention of the craniofacial prosthesis is a great problem despite the satisfactory esthetic results.

Identifying potential predictors of pain-related disability in Turkish patients with chronic temporomandibular disorder pain.

Background: The aims of this study were to examine whether patients' psychosocial profiles influence the location of pain, and to identify the clinical and psychosocial predictors of high levels of pain-related disability in temporomandibular disorders (TMD) patients with chronic pain at least 6 months in duration.

Methods: The Research Diagnostic Criteria of TMD (RDC/TMD) data for Axis I and II were obtained for 104 consecutive patients seeking treatment.Data were analyzed using descriptive statistics, t-test, Mann-Whitney U-test, chi-square test, One-way ANOVA, Kruskal-Wallis test, and binary multiple logistic regression tests.

Manufacturing implant supported auricular prostheses by rapid prototyping techniques.

Maxillofacial prostheses are usually fabricated on the models obtained following the impression procedures. Disadvantages of conventional impression techniques used in production of facial prosthesis are deformation of soft tissues caused by impression material and disturbance of the patient due to. Additionally production of prosthesis by conventional methods takes longer time.

Effects of different abutment connection designs on the stress distribution around five different implants: a 3-dimensional finite element analysis.

The stability of the bone-implant interface is required for the long-term favorable clinical outcome of implant-supported prosthetic rehabilitation. The implant failures that occur after the functional loading are mainly related to biomechanical factors. Micro movements and vibrations due to occlusal forces can lead to mechanical complications such as loosening of the screw and fractures of the abutment or implants.
