Dentistry

Objective: This study aimed to compare the accuracy of condylar positioning between 2 computer-guided orthognathic surgical protocols: a waferless screw hole plate locating (WSL CPD) technique versus an occlusal splint with distal extending arms (OWDA-CPD) approach. Materials and Methods: Twenty-four patients requiring mandibular orthognathic surgery (class II or III deformities) were randomly allocated into 2 groups (n=12 each). Group I underwent a waferless protocol utilizing 3D-printed osteotomy and screw hole locating guides, while group II received an occlusal splint with distal extensions for condylar positioning. Preoperative and postoperative cone-beam computed tomography (CBCT) scans were used to assess condylar displacement in …

Aim: The aim of the study is to evaluate the efficacy of three-dimensional bone augmentation in maxillary atrophied alveolar ridges by comparing the utilization of bone marrow aspirate concentrate along with a mix of autograft and xenograft versus autograft and xenograft alone. utilizing patient-specific titanium meshes. Subjects and methods: Ten patients experiencing severe vertical and horizontal deficiencies in the entire maxillary arch underwent guided bone regeneration. Utilizing specialized software, virtual bone augmentation were performed for the deficient ridge across the entire maxillary alveolus. This process involved generating virtually augmented models to guide the preoperative prebending of titanium meshes. In the …

Anatomical Analysis Of Inferior Alveolar Nerve Relation To Mandibular Posterior Teeth Using Cone Beam Computed Tomography: A Retrospective Radiographic Analysis Study, Shehabeldin Mohamed Saber Prof.Dr.

Dentistry

Introduction: Cone beam computed tomography (CBCT) is reliable in the assessment of structures related to teeth. The assessment of the inferior alveolar neurovascular (IAN) bundle location using CBCT is considered one of its prime uses in different mandibular surgeries. Methodology: Retrospective CBCT data of patients presented to the institute were assessed to measure relations of IAN. Measurements were taken to assess the bone thickness adjacent to IAN, the superior-inferior dimension between the canal and the teeth, and the dimension between the canal and the inferior border of the mandible. Results: Out of the 170 patients the root apices nearest to …

Aesthetic Management Of Peri-Implant Soft Tissue Dehiscence. A Case Report Of A Combined Perio Restorative Approach, Ahmed Hamdy, Dalia M. Ghalwash

Dentistry

This case report designates a combined perio restorative technique in the management of peri-implant 3-dimensional soft tissue defects in an esthetic zone. A staged approach was implemented to treat this case; the first stage was planned to treat the horizontal defect around the implant, in which crown was removed, and coronally advanced flap with connective tissue graft were used to treat the soft tissue defect. At the second stage, a modified coronally advanced flap with connective tissue graft was used to augment the vertical defect, and no vertical releasing incision was made in this stage to maximize the blood supply …
