Maxillary bone augmentation with calvarial bone graft for immediate full-arch rehabilitation: Insights from a 10-year proof-of-concept retrospective analysis.

Objective: Evaluate the long-term outcomes of full-arch rehabilitation using immediate dental implant placement and continuous functional loading with full-fixed dental prostheses (FFDPs).

Materials And Methods: Fifty-six patients received temporary implants (n = 327) at maxillary augmentation with calvarial bone. A provisional acrylic FFDP was immediately loaded onto these implants.

Tracking the Molecular Fingerprint of Head and Neck Cancer for Recurrence Detection in Liquid Biopsies.

The 5-year relative survival for patients with head and neck cancer, the seventh most common form of cancer worldwide, was reported as 67% in developed countries in the second decade of the new millennium. Although surgery, radiotherapy, chemotherapy, or combined treatment often elicits an initial satisfactory response, relapses are frequently observed within two years. Current surveillance methods, including clinical exams and imaging evaluations, have not unambiguously demonstrated a survival benefit, most probably due to a lack of sensitivity in detecting very early recurrence.

Cone Beam Computed Tomography Imaging in Dental Implants: A Primer for Clinical Radiologists.

With the introduction of cone beam computed tomography (CBCT) into dentistry in the 1990s, radiologists have become more frequently involved in dental implant planning. This article describes the information that should be included in a radiology report to achieve a successful implantation. The justification to use CBCT during the preoperative planning phase is based on the need to evaluate patient-specific anatomy in detail (general condition of the jaw, bone quantity, and bone quality), the application of more advanced surgical techniques (maxillary sinus augmentation procedure, zygomatic implants), and the integrated presurgical planning and virtual patient approach.

Intraoperative Navigation and Cone Beam Computed Tomography for Restoring Orbital Dimensions: A Single-Center Experience.

Background: Correction of post-traumatic orbital defects remains a challenge for the maxillofacial surgeon. We examined the added value of combined intraoperative (IO) navigation and IO cone beam computed tomography (CBCT).

Materials And Methods: A retrospective cohort study was performed in all consecutive patients requiring unilateral post-traumatic orbital surgery between January 2012 and December 2018.

Evaluation of Quality of Life After Mandibular Reconstruction Using a Novel Fixed Implant-Supported Dental Prosthesis Concept: A Pilot Study.

Purpose: To evaluate the feasibility and efficacy of a novel concept of early loaded (ie, within 2 weeks) implant-supported fixed dental prostheses (ISFDP) for patients who underwent mandibular reconstruction.

Materials And Methods: All patients requiring mandibular reconstruction between July 2013 and March 2016 at AZ Sint-Jan Brugge-Oostende AV were screened for dental rehabilitation according to the proposed concept. Of 17 patients, 10 were eligible for inclusion.

Postoperative Respiratory Complications After Cleft Palate Closure in Patients With Pierre Robin Sequence: Operative Considerations.

Background: In cleft palate surgery, there is currently no consensus on the management of patients with Pierre Robin Sequence (PRS). The authors aimed to evaluate the treatment strategy of cleft palate in our centers, with emphasis on patients with PRS, as the authors noted some patients with severe respiratory distress. Moreover, the authors aimed to investigate the prevalence of postoperative respiratory complications, using a modified-Furlow palatoplasty in combination with intravelar veloplasty in both patients with PRS and patients with non-PRS.

Transoral Fixation of Bicortical Screws Is Safe and Feasible for Lower Jaw Osteotomies.

Purpose: Transoral placement of bicortical screws is a rigid fixation method in orthognathic surgery that is used less often than transbuccal placement. The aim of this study was to examine the postoperative outcome of transoral bicortical screw insertion during orthognathic surgery and to compare it with the more common transbuccal fixation technique.

Materials And Methods: A retrospective cohort study was conducted.

Peri-implant bone changes following tooth extraction, immediate placement and loading of implants in the edentulous maxilla.

The aim of this study was to clinically and radiographically evaluate peri-implant bone level changes after rehabilitation of a fully edentulous maxilla by placement of six implants in either fresh extraction sites or healed edentulous ridges up till 18 months after implant placement. Twenty patients with a terminal dentition in the maxillae (11 men, 9 women) received a total of 120 OsseoSpeed implants; 118 implants could be loaded immediately of which 59 were placed in extraction sockets and 59 were placed in healed sites. Within 24 h after surgery, all patients received a chairside-assembled, fibre-reinforced temporary fixed prosthetic reconstruction in occlusion.

A cone-beam computed tomography triple scan procedure to obtain a three-dimensional augmented virtual skull model appropriate for orthognathic surgery planning.

The aim of this study was to present a new approach to acquire a three-dimensional virtual skull model appropriate for orthognathic surgery planning without the use of plaster dental models and without deformation of the facial soft-tissue mask. A "triple" cone-beam computed tomography (CBCT) scan procedure with triple voxel-based rigid registration was evaluated and validated on 10 orthognathic patients. First, the patient was scanned vertically with a wax bite wafer in place (CBCT scan No1).

The use of a wax bite wafer and a double computed tomography scan procedure to obtain a three-dimensional augmented virtual skull model.

A detailed visualization of the interocclusal relationship is essential in a three-dimensional virtual planning setup for orthognathic and facial orthomorphic surgery. The purpose of this study was to introduce and evaluate the use of a wax bite wafer in combination with a double computed tomography (CT) scan procedure to augment the three-dimensional virtual model of the skull with a detailed dental surface. A total of 10 orthognathic patients were scanned after a standardized multislice CT scanning protocol with dose reduction with their wax bite wafer in place.

Anterior transmandibular osteodistraction: clinical and model observations.

Introduction: The aim of this paper was to study the effect of transmandibular distraction on the periodontal and dental structures, and the initial movements of the mandibular halves, when using an axial plane non-rigid bone-borne distractor (TMD).

Material And Methods: Fourteen patients undergoing bimaxillary transverse osteodistraction had their six lower anterior teeth assessed for mobility, sensitivity, and pocket depth. Recordings were made pre-operatively, post-distraction, post-consolidation and at 1-year follow-up.

A prospective study on infectious complications in orthognathic surgery.

Aim: According to an earlier study in 2000, 4.7% of patients undergoing corrective facial orthopaedic surgery in this unit suffered a postoperative wound infection. In 1998, the Belgian Government recommended stricter rules for infection prophylaxis and a new antibiotic protocol similar to that proposed by Peterson (1990) was implemented in this unit.

Problems, obstacles and complications with transpalatal distraction in non-congenital deformities.

Introduction: The transpalatal distractor is a bone-borne device that eliminates negative orthodontic effects during and after maxillary expansion. It produces virtually parallel expansion in the coronal plane. Orthodontic appliances can be installed at an earlier date than when tooth-borne expanders are used.
