Effectiveness of orthognathic surgery by maxillomandibular advancement combined with soft tissue surgery as curative treatment for obstructive sleep apnea syndrome.

Objective/background: The aim of this study was to compare the efficacy of orthognathic surgery combined with soft tissue surgery with that of soft tissue surgery alone as curative treatments for moderate to severe obstructive sleep apnea (OSA) syndrome.

Patients/methods: This retrospective cohort study included 50 patients aged ≥18 years who underwent orthognathic surgery combined with soft tissue surgery or soft tissue surgery alone for OSA syndrome (apnea-hypopnea index [AHI]: >15). The primary outcome was the improvement in AHI measured by overnight in-laboratory polysomnography before and at 6 months after the surgical treatment by.

Pre-implant surgery complexity for achieving implant-supported prosthetic rehabilitation in oligodontia patients: a retrospective study.

Introduction: Oligodontia is a rare dental developmental pathology that requires prolonged, complex and multidisciplinary treatment. Although bone augmentation is frequently required during a complete implant treatment of oligodontia. Therefore, we evaluated the ability to predict pre-implant surgery complexity based on age, number of missing teeth, and number of implants required to achieve implant-supported prosthetic rehabilitation.

Systematic review of the histological and functional effects of botulinum toxin A on masticatory muscles: Consideration in dentofacial orthopedics and orthognathic surgery.

Introduction: Botulinum toxin type A causes muscle paralysis and is widely used in the masticatory muscle for stomatognathic diseases, such as temporomandibular disorder, bruxism, or masseteric hypertrophy. Nonetheless, its muscular effect remains unclear. Better understanding could aid improved use and perhaps new indications, particularly in dentofacial orthopaedics and orthognathic surgery.

Evolution and spread of multiadapted pathogens in a spatially heterogeneous environment.

Pathogen adaptation to multiple selective pressures challenges our ability to control their spread. Here we analyze the evolutionary dynamics of pathogens spreading in a heterogeneous host population where selection varies periodically in space. We study both the transient dynamics taking place at the front of the epidemic and the long-term evolution far behind the front.

Engineering Precise Interconnected Porosity in β-Tricalcium Phosphate (β-TCP) Matrices by Means of Top-Down Digital Light Processing.

This study evaluated the biocompatibility and accuracy of 3D-printed β-tricalcium phosphate (β-TCP) pure ceramic scaffolds. A specific shaping process associating a digital light processing (DLP) 3D printer and a heat treatment was developed to produce pure β-TCP scaffolds leaving no polymer binder residue. The β-TCP was characterised using X-ray diffraction, infrared spectroscopy and the detection of pollutants.
