Evaluation and comparison of retention and patient satisfaction with milled polyetheretherketone versus metal maxillary obturators.

Statement Of Problem: Metal and polyetheretherketone (PEEK) have been used to rehabilitate maxillary defects with obturators, each having advantages and disadvantages. However, patient satisfaction with the obturator retention of each material is unclear.

Purpose: The purpose of this crossover clinical study was to compare retention and patient satisfaction between a milled cobalt chromium and a milled PEEK framework, each with a hollow bulb extension in polymethyl methacrylate (PMMA).

Personality and mental disorders: sensitive character, melancholic type, and addenda.

A traditional view in psychiatry is that personality disorders or traits are intimately related to primary mental disorders. Psychic functions with common roots might be constitutive of personality and psychosis or other disorders. Hoche held that paranoia, mania and melancholia lie in the normal psyche, and Kraepelin conceded such a view, explicitly implying personality.

Polyetheretherketone subperiosteal implant retaining a maxillary fixed prosthesis: A case series.

Statement Of Problem: Patients needing dental rehabilitation of a complete atrophic maxilla would benefit from simplified treatment plans.

Purpose: The purpose of this case series was to demonstrate the prosthetic management of 4 edentulous patients with severe maxillary ridge resorption who declined multiple stage surgery and sought a fixed prosthesis in single-stage surgery.

Material And Methods: The patients were provided with completely digital computer-aided designed and computer-aided manufactured (CAD-CAM) polyetheretherketone (PEEK) maxillary subperiosteal frameworks, which were surgically placed in a 1-step procedure.

Neuropsychiatric and sleep study in autosomal dominant dopa-responsive dystonia.

Introduction: Although the diurnal fluctuation of motor dysfunction, reversible with small doses of dopamine, is a cornerstone for the phenotype of the autosomal dominant Segawa syndrome, the non-motor symptoms of this neurotransmitter deficiency have still received limited attention.

Objective: This study aims to evaluate non-motor symptoms of this dopa-responsive dystonia through an intrafamilial comparative cross-sectional study.

Methods: Seventeen individuals with a c.
