Maxillofacial AbnormalitiesJaw Abnormalities6 more

Research studies continues to attempt testing modifications to refine the treatment protocols through computer assisted design or computer-generated surgical Wafer splints, have greatly revolutionized the incorporation of digital imaging and 3D design in Orthognathic surgery. Integrating computer guided technology in orthognathic surgery aims to to simplify workup and reduce surgical errors, eliminate occlusal discrepancy, increase the realignment accuracy of the distal segments according to the preoperative plan. Implementing a waferless technique raised the question of efficiency versus the use of occlusal wafers and whether it has a significant measurable effect on the surgical outcome and objectives. Rationale for conducting this study is to assess the difference between the effect of computer guided waferless technique and computer guided technique with occlusal wafer on accuracy of postoperative occlusion and condylar position. .

Mandibular Reconstruction With Axially Vascularised Bone Substitutes

Mandibular Deficiency

Mandibular reconstruction is necessary following trauma, tumour resections and extensive infections resulting in severe defects of the mandibular arch. For reconstructing large and recurrent defects, the vascularized free flaps are currently regarded as the gold standard. The use of these flaps, however, presents several major inconveniences. Although regenerative medicine in the field of cranio-maxillofacial reconstruction has now become a common practice, the main technical challenge is still related to vascularization of the regenerated tissue in large defects. Axial vascularization of constructs using a microvascular arteriovenous fistula/loop (AV loop) aims at providing the construct with blood supply through a defined and dedicated vascular axis. This technique was successfully demonstrated in some case reports, but was never applied in the craniofacial region. The current study aims to apply and assess the technique of axial vascularization using the AV loop of a bone substitute to reconstruct mandibular defects.

A Fatty Flap Taken From the Double Chin for Chin Enhancement: a New Surgical Technique

AdiposityMicrognathism

The double chin is a troublesome component of the lower third of the face. It gives an embarrassing and unpleasant facial appearance to both men and women leading them to ask for liposuction. Moreover, a "receding chin" causes blunting of the cervico-mental angle, a fleshy appearing neck, a disproportion in the profile line of the face with a prominent looking nose, and an irregular mandibular border. This study is about an innovative surgical procedure: Instead of doing liposuction of the double chin, the investigators used the fat of this area as a flap to improve a "receding chin". hence both the double chin and the receding chin are treated.

Applicability Clinic of Cement Portland Structural White in Endodontic Surgery

Mandibular Hypoplasia

Thirty teeth twelve patients, two female and a male, who had persistent periradicular lesions were selected to participate in this study. The lesions were diagnosed with cone-beam computed tomography (cone-beam CT; Model i-Cat 17-19, Imaging Sciences International LLC).In patients with two teeth to be treated, a tooth was retroobturado with PBEA cement, (experiment) and another tooth was retroobturado with MTA cement (control). There was significance for the two cements on the repair of wounds. Key words: Apicoectomy; Oral Surgery; Biocompatible Materials; Dental Cements; Translational Medical Research

Comparing Stability and Cost-Effectiveness of 3 Bicortical Screws Vs Adjustable Plate and 2 Bicortical...

Mandibular Hypoplasia

In this current study a comparison between 3 positional screws versus the adjustable plating system in conjunction with 2 positional screws. The patients will be selected to have retrognathic mandible requiring advancement. Hypothetically the advantage of the adjustable plating system will be compared with the three positional screws. In theory, the investigators will be using the inherent advantage of the intraoperative flexibility of the adjustable plating system in verifying the position of the proximal segment (condylar segment), hence eliminating the immediate postoperative relapse that is reported with using three positional screws. This will be evaluated both clinically and cephalometrically.
