Comparison of Extramaxillary Anchored Implants, Tilted Implants, or Sinus Elevation Concepts on Stress Distribution in Atrophic Maxilla: A Finite Element Analysis.

Purpose: To determine the von Mises stress values of extramaxillary implants anchored in zygomatic bone, known as zygomatic implants, abutments, superstructures, and principal stress values of bone under occlusal forces and to compare them with tilted implants and sinus elevation concepts. The hypothesis of the study was that there would be higher stress on zygomatic implants under occlusal forces compared with tilted implants and the sinus elevation technique due to the more angled placement of the zygomatic implants.

Materials And Methods: Finite element analysis (FEA) was used to apply a force of 600 N (75 N premolars and 150 N first molar) vertically and at an angle of 20 degrees to the hybrid prosthesis with three different concepts-zygomatic implants, tilted implants, and sinus elevation-in D2 bones in six separate models.

Is zirconium or stainless steel the most suitable crown material for less dentin stress in endodontically treated teeth?

Background: Stainless steel crowns (SSCs), which have been used frequently in the treatment of first permanent molars in children until now, has become less applicable due to its poor aesthetic appearance. Zirconia crowns (ZCs) have become more popular due to their aesthetic advantage. However, stress transmission of ZCs to dental tissues under occlusal forces in endodontically treated teeth has not been described.

Dentist-patient communication on dental anxiety using the social media: A randomized controlled trial.

The purpose of the present study was to assess the effects of dentist-patient communication via social media on dental anxiety and to determine the appropriate timing of such communications. In this randomized, double-blinded and controlled trial, we used Instagram's quick replies system to answer patients' questions to alleviate dental anxiety for patients undergoing impacted teeth extraction under local anesthesia. Patients were assigned randomly into four groups according to the timing of such communications: only after (group 1, n = 36), only before (group 2, n = 35), before and after the operation (group 3, n = 36), and a control group who received no communication on social media (group 4, n = 36).

Comparison of the Efficacy of Botulinum Toxin, Local Anesthesia, and Platelet-Rich Plasma Injections in Patients With Myofascial Trigger Points in the Masseter Muscle.

Purpose: Masticatory myofascial trigger points (TrP) are one of the major causes of nondental pain in the orofacial region. Intramuscular injections are considered the first-line treatment for myofascial TrPs. The objectives of this study were to evaluate and compare the effectiveness of local anesthesia (LA), botulinum toxin (BTX), and platelet-rich plasma (PRP) injections for the treatment of myofascial TrPs in the masseter muscle.

A comparative study between zirconia and titanium abutments on the stress distribution in parafunctional loading: A 3D finite element analysis.

Background: Zirconia has become a popular biomaterial in dental implant systems because of its biocompatible and aesthetic properties. However, this material is more fragile than titanium so its use is limited.

Objectives: The aim of this study was to compare the stresses on morse taper implant systems under parafunctional loading in different abutment materials using three-dimensional finite element analysis (3D FEA).

Buccal vascular malformation with multiple giant phleboliths: a rare case presentation and review of the literature.

Purpose: The purpose of this study was to describe a case and to review the diameters, symptoms, locations, and treatment methods for vascular malformations (VMs) with phleboliths. Our case report is probably the first to mention this observation because of sizes and large number of phleboliths in buccal region.

Case Presentation: A 26-year-old male patient was referred to Ordu University, Faculty of Dentistry, Department of Oral and Maxillofacial Surgery for the evaluation and management of a painless tender swelling in the left buccal region.

Results of Combined, Single-Session Arthrocentesis and Dextrose Prolotherapy for Symptomatic Temporomandibular Joint Syndrome: A Case Series.

Objective: Arthrocentesis and prolotherapy are nonsurgical treatments for temporomandibular joint (TMJ) diseases. This study aimed to evaluate the treatment of hypermobility, pain, and displacement of the TMJ by consecutively performing arthrocentesis and prolotherapy in the same session.

Materials And Methods: In this study, 10 adults with disc displacement and painful, hypermobile TMJ were selected.

The prevalence of foreign bodies in jaw bones on panoramic radiography.

Objective: Foreign bodies can be deposited in the oral cavity either by traumatic or iatrogenic injury. The most common foreign bodies of iatrogenic origin encountered are restorative materials, like amalgam, and root canal fillings. The aim of this study was to determine the prevalence of foreign bodies detected with panoramic radiography in the jawbones, as well as to evaluate the etiology and characteristics of these pathologies.
