Feasibility of iterative closest point algorithm for accuracy between virtual surgical planning and orthognathic surgery outcomes.

Purpose: To evaluate the feasibility of iterative closest point (ICP) algorithm for assessing the accuracy between virtual surgical planning (VSP) and outcomes in orthognathic surgery.

Materials And Methods: VSP and results of surface mesh (SM0 and SM1) from CBCT scans of 25 patients who had been undergone bi-maxillary orthognathic surgery were converted into STL-format files and then imported to Geomagic software for semi-automatic alignment. ICP algorithm was used to calculate mean deviations (MD) and root mean square (3D error) at different calibrations of ±2 mm (T1), ±5 mm (T2) and ±10 mm (T3), with workflow being performed by two evaluators.

Alteration of Occlusal Plane in Orthognathic Surgery: Clinical Features to Help Treatment Planning on Class III Patients.

Dentofacial deformities (DFD) presenting mainly as Class III malocclusions that require orthognathic surgery as a part of definitive treatment. Class III patients can have obvious signs such as increasing the chin projection and chin throat length, nasolabial folds, reverse overjet, and lack of upper lip support. However, Class III patients can present different facial patterns depending on the angulation of occlusal plane (OP), and only bite correction does not always lead to the improvement of the facial esthetic.

Accuracy of computer-guided surgery for dental implant placement in fully edentulous patients: A systematic review.

Assess clinical studies regarding accuracy between virtual planning of computer-guided surgery and actual outcomes of dental implant placements in total edentulous alveolar ridges. A PubMed search was performed to identify only clinical studies published between 2011 and 2016, searching the following combinations of keywords: "Accuracy AND Computer-Assisted Surgery AND Dental Implants." Study designs were identified using the terms: Case Reports, Clinical study, Randomized Controlled Trial, Systematic Reviews, Meta-Analysis, humans.

Survival in patients with oral and maxillofacial diffuse large B-cell lymphoma.

The purpose of this study was to determine the survival and prognostic factors of patients with diffuse large B-cell lymphoma (DLBCL) of the oral cavity and maxillofacial region. Retrospectively, the clinical records of patients with a primary diagnosis of DLBCL of the oral cavity and maxillofacial region treated at the A.C.

Malignant lymphoma of the oral cavity and the maxillofacial region: overall survival prognostic factors.

Objective: To identify the overall survival and prognostic factors of malignant lymphoma of the oral cavity and the maxillofacial region.

Study Design: Clinical records data were obtained in order to determine overall survival at 2 and 5 years, the individual survival percentage of each possible prognostic factor with the actuarial technique, and the survival regarding the possible prognostic factors with the actuarial technique and the Log-rank and Cox's regression tests.

Results: Of 151 subjects, an overall survival was 60% at 2 years, and 45% at 5 years.

Mineralized tissue formation associated with 2 different dental implant designs: histomorphometric analyses performed in dogs.

The clinical success of dental implants might be associated with such factors as installation technique, implant shape, size, material, and screw threads. Therefore, the aim of this study is to analyze mineralized tissue formation on the screw threads of conical and cylindrical dental implants. This study includes 7 beagle dogs that had the lower premolars extracted.
