The effect of different denture cleansing solutions on the retention of polyetheretherketone locator attachments.

Purpose: Prosthetic cleansing solutions have been reported to cause retention loss in implant locator attachments due to the chemical alterations of these attachments. This study aimed to investigate the effects of different denture cleansing solutions on attachments with different retention values.

Materials And Methods: In this study, 160 polyetheretherketone locator attachments were divided into 4 groups according to their attachment retention values (yellow, pink, clear, and violet).

Proximity of healthy posterior teeth to the maxillary sinus floor in relation to mucosal thickening: a CBCT study.

Objectives: To evaluate the relationship between proximity of the root apices of healthy maxillary posterior teeth to the maxillary sinus floor (MSF) and mucosal thickening (MT) of the MSF using cone beam computed tomography (CBCT).

Methods: Eighty-four CBCT images obtained from the patients, aged between 20 and 70 years with healthy and fully dentate maxillary posterior sextants, were included. The anatomical relationship between root apices of maxillary posterior teeth and MSF, was evaluated: (Type 1: no contact, Type 2: at least one root apex in contact, Type 3: at least one root apex protruding into MSF).

Treatment of residual pockets using an oscillating chitosan device versus regular curettes alone-A randomized, feasibility parallel-arm clinical trial.

Background: A brush made of chitosan has shown to be an effective and harmless device for non-surgical treatment of mild to moderate peri-implantitis. To date, no study has evaluated the use of a chitosan brush in the non-surgical treatment of residual pockets in periodontal treatment.

Methods: Seventy-eight patients with periodontitis were included in this multicenter, randomized, examiner-blind clinical trial of 6 months duration.

Reliability of Measurements on Plaster and Digital Models of Patients with a Cleft Lip and Palate.

Objective: The purpose of this study was to determine (1) the more and less reliable measurements/methods and (2) the influence of knowledge and skill on the inter-examiner, intra-examiner, and inter-method reliability of nasolabial measurements on plaster casts and three dimensional (3D) stereophotogrammetric images of casts in infants with an unrepaired unilateral cleft lip and palate (UUCLP).

Methods: Preoperative extraoral plaster casts from 42 patients with UUCLP were measured with a digital caliper, and the image acquisition of casts was performed with the 3dMDface stereophotogrammetry system (3dMD, Atlanta, GA). Two examiners (one postgraduate student, one lecturer) evaluated 19 nasolabial measurements in two separate sessions.

Evaluation of the Impact of Interdisciplinary Case-Based Courses in Dental Education on Smile Evaluation Skills of Undergraduate Students.

Objective: The purpose of the present study was to compare the perception of smile aesthetic between 3rd-, 4th-, and 5th-year dental students to identify if interdisciplinary courses have an impact on the attitudes of students.

Methods: A total of 118 dental students (3rd-, 4th-, and 5th-year; N=43, 43, and 32, respectively) assessed the aesthetic attractiveness of four smile photographs (normal, high, low, and asymmetric smile lines). To enhance the crown, length-to-width ratio and color Digital Smile Design (DSD) were applied to all photographs, and then scoring was performed by using the Visual Analog Scale (VAS).

Patient with Severe Skeletal Class II Malocclusion: Double Jaw Surgery with Multipiece Le Fort I.

A 22-year-old woman with severe skeletal Class II malocclusion was referred to our clinic. A clinical examination revealed a convex soft tissue profile and increased teeth and gingiva exposure both while smiling and in the natural rest position. She had Class II molar and canine relationship with increased overjet, moderate crowding in both upper and lower jaws, and proclined upper and lower incisors.

Three-Dimensional Imaging in Orthodontics.

Orthodontic records are one of the main milestones in orthodontic therapy. Records are essential not only for diagnosis and treatment planning but also for follow-up of the case, communicating with colleagues, and evaluating the treatment outcomes. Recently, two-dimensional (2D) imaging technology, such as cephalometric and panoramic radiographs and photographs, and plaster models were routinely used.

Treatment of a Class II Case with Palatally Inserted Distalization Mechanics in an Epilepsy Patient.

This case report describes the protocol employed in the treatment of a patient with Class II malocclusion with mechanics including palatally positioned miniscrews. Treatment included the distalization of maxillary posterior teeth with mechanics including 2 miniscrews positioned on the palatal side. After a certain amount of distalization was achieved, the maxillary arch was bonded with Roth prescription brackets while the appliance was still active.

Which Orthodontic Wire and Working Sequence Should be Preferred for Alignment Phase? A Review.

The key to a successful orthodontic therapy depends not only on manual skills and knowledge about treatment steps, but also on knowledge and choice of materials used. One of the major components of fixed orthodontic therapy is the choice of wires. Orthodontic wires are defined as devices consisting of a wire conforming to the alveolar or dental arch, used as an anchorage in correcting irregularities in the position of the teeth.

Investigation of the Relationship between Increased Vertical Overlap with Minimum Horizontal Overlap and the Signs of Temporomandibular Disorders.

Purpose: The purpose of this study was to test the null hypothesis that there was no relationship between increased vertical overlap (vertical overlap ≥4 mm) with minimal horizontal overlap (horizontal overlap ≤2 mm) and the signs of temporomandibular disorders.

Materials And Methods: Thirty participants (20 women, aged 20 to 45 years) with increased vertical overlap and minimal horizontal overlap, and 30 participants (20 women, aged 20 to 45 years) with no contact between the anterior teeth (control group) were examined. Diagnoses, psychological status (depression and nonspesific physical symptoms), and chronic pain severity were judged according to the Research Diagnostic Criteria for Temporomandibular Disorders and then compared.

Comparison of different grinding procedures on the flexural strength of zirconia.

Statement Of Problem: The surface of zirconia ceramic is damaged during grinding, which may affect the mechanical properties of the material.

Purpose: The purpose of this study was to compare the biaxial flexural strength of zirconia after different grinding procedures and to measure the temperature rise from grinding.

Material And Methods: Forty disk-shaped zirconia specimens (15 × 1.
