Maxilla management in "phase II" skeletal surgery for obstructive sleep apnea.

This study investigates the management of patients with obstructive sleep apnea (OSA) who have previously undergone palatal surgery and subsequently undergo maxillomandibular advancement (MMA). The research entails a retrospective analysis of phase II MMA cases from 2017 to 2022. Data encompassing demographics, clinical profiles, pre- and post-operative polysomnographic and radiological findings, surgical techniques, and complications were collected.

Resonance Frequency Analysis to Assess the Stability of Immediate Implants: A Retrospective Clinical Trial.

Adequate implant primary stability is a key factor to obtain osseointegration and can be measured at insertion by insertion torque (IT) and at different timepoints with resonance frequency analysis (RFA), expressed as an implant stability quotient (ISQ). This retrospective study investigated the correlation between ISQ and IT at implant insertion. All patients who were eligible for this single-cohort retrospective clinical trial were treated with an immediate implant.

Preformed customized healing abutments in a biologically oriented preparation technique procedure: a 3-year retrospective case-control study.

Aim: The objective of the present study was to determine the 3-year clinical and dimensional soft tissue change following implant placement in healed sites before and after loading with either customized or conventional healing abutments.

Materials And Methods: Premolar/molar implants were immediately loaded with either provisional and customized abutments without finishing lines according to the principles of the biologically oriented preparation technique (BOPT; test group) or conventional healing abutments (control group). Three months later, the definitive crowns were fabricated.

Clinical and radiographic evaluation of transalveolar two-step osteotome-mediated sinus floor elevation versus sinus augmentation with displacement of the palatal wall in lateral direction coupled to alveolar ridge split technique: A 3-year retrospective study.

Introduction: The present study aimed to examine the middle-term effects of transcrestal double-sinus elevation (TSFE) versus alveolar/palatal split expansion technique (APS) and simultaneous implant placement in the augmented sinus.

Null Hypothesis: there were no differences between groups.

Material & Methods: Magnetoelectric device was used for bone augmentation and expansion techniques in long-standing edentulous patients with a deficiency in vertical height in the posterior maxilla (3mm to 4mm residual bone height): TSFE group, or two-stage process with a first transcrestal sinus floor augmentation and a second sinus floor elevation with immediate implant placement; APS group, or "dual split and dislocation" of the two cortical bony plates towards the sinus and palatal side.

Lateral Displacement of Maxillary Sinus Palatal Wall: A 1-Year Retrospective Computerized Tomography Study.

Purpose: To examine the short-term outcomes of maxillary sinus augmentations consisting of laterally and apically displacing the palatal wall through a transcrestal approach.

Materials And Methods: The maxillary sinus floor was fractured in its palatal aspect by allowing a displacement in the buccal and apical direction with a magnetoelectric system. A medial displacement of the alveolar crest in its palatal bony plate was performed at the same time.

Standardization of three-dimensional pose of cylindrical implants from intraoral radiographs: a preliminary study.

Background: To introduce a theoretical solution to a posteriori describe the pose of a cylindrical dental fixture as appearing on radiographs; to experimentally validate the method described.

Methods: The pose of a conventional dental implant was described by a triplet of angles (phi-pitch, theta-roll, and psi-yaw) which was calculated throughout vector analysis. Radiographic- and simulated-image obtained with an algorithm were compared to test effectiveness, reproducibility, and accuracy of the method.

Treatment decision-making for a post-traumatic malocclusion in an elderly patient: A case report.

Traumatic dental injuries in elderly patients are a rising trend due to demographic and social changes of the population. Older dentulous patients in good health have become increasingly common. The development of a post-traumatic malocclusion is a common sequela resulting from mandibular condyle fracture, as in the case reported in this paper.

Neck dissection with harmonic instruments and electrocautery: a prospective comparative study.

Background: Harmonic instruments are becoming popular in head and neck surgeries. In this prospective, randomized study, the efficacy of the harmonic instruments and electrosurgical technique is compared.

Materials And Methods: A total of 48 patients undergoing unilateral neck dissection were divided into two groups.

Bilateral Harvesting of a Fibula Free Flap: Assessment of Morbidity.

Purpose: To investigate morbidity related to harversting of bilateral fibula free flap for head and neck reconstruction using subjective and functional tests.

Methods: Patients were retrospectively evaluated using point evaluation system (PES) and balance evaluation systems test (BESTest) questionnaires to assess morbidity related to surgery.

Results: Five patients were enrolled in the study.

Neonatal mandibular distraction in a patient with Treacher Collins syndrome.

The purpose of this study was to analyze a case of mandibular distraction in a case of Treacher Collins syndrome. Mandibular distraction is an adequate surgical treatment of patients with Pierre Robin sequence and represents an alternative to tracheostomy. In severe hypoplastic cases or when three-dimensional vector control or gonial angle control is necessary, extraoral bidirectional or multidirectional devices have an advantage over intraoral devices.
