Cone beam computed tomography and prosthodontic rehabilitation of cleidocranial...

The aim of this study is to present a clinical case of a male patient with cleiodocranial dysostosis, in which the cone beam tomography was crucial in the decision making regarding the type of prosthetic rehabilitation to establish.

Retrospective evaluation of therapeutic outcomes of functional appliances combi...

Functional appliances were developed to correct mainly Class II malocclusions in growing children but the influence of those appliances on craniofacial growth is still controversial, even when used in combinations with headgear. The aim of this retrospective study was to investigate skeletal, dental and tegumental cephalometric modifications induced by Teuscher activator. This study was accomplished in a mixed ...

Mouthguard for Orthodontic Patient Trumpet Player

Mouthguards reduce the occurrence and the severity of damages on intraoral tissues absorbing and diffusing the energy of the impact. The brass instruments, also known as 'lip-vibrated instruments, are played by propelling air through sealed lips. The pressure applied on the lips can cause damage and bruising. The use of mouthguards can prevent those injuries producing some relief on orthodontics patients playin...

A clinical study of condylar position of three biotypological facial groups.

Objectives: Orthodontic diagnosis and treatment related to the orthopaedic position of centric relation (CR) requires a comprehensive study of the condylar position (Roth, 1981; Cordray, 2006). According to the craniofacial architecture, the hyperdivergent facial type seems to be more prone to condyle displacement than other facial groups. Therefore, it was put into hypothesis that it is on the hyperdivergent ...

IL-1 polymorphisms may predict unsuccessful dental implants?

Aim The aim of this study was to analyse the possible association between no success of dental implants and two polymorphisms, IL1A (-889) and IL1B (+3953), in a Caucasian Portuguese population, and a possible relationship with other potential risk variables associated with a peri-implant disease. Material and Methods 155 unrelated Caucasian individuals, were divided into 2 groups: 100 with successful dental im...

Feasibility of reusing orthodontic bands after trial in the mouth. Control of c...

Given the scarcity of studies in the area of cross-infection in Portugal, we carried out a research study aimed at evaluating the effectiveness of two methods of sterilization and disinfection of orthodontic bands, after being tested in the mouth. Simultaneously, we tested the protocol of the Department of Orthodontics of the Dental Faculty of Oporto University (DO-DFOU). 35 orthodontic bands were placed in the...

Condylar displacement on three different biotypological facial groups

This work intended to investigate centric slide (CS) on different facial skeletal groups. With this aim in mind, three different groups hyperdivergent, hipodivergent and an intermediate one were studied and compared. The tests performed allowed to identify a statistically more significant vertical displacement in hyperdivergent group while the sagittal displacement was more pronounced in hypodivergent group wit...
