AIM AND SCOPE: Result assessment in cleft surgery is a technical challenge and requires the development of dedicated morphometric tools. Two cohorts of patients managed according to two different protocols were assessed at similar ages and their palatal shape was compared using geometric morphometrics. Material and Methods Ten patients (protocol №1) benefited from early lip closure (1-3 months) and secondary combined soft and hard palate closure (6-9 months); 11 patients (protocol №2) benefited from later combined lip and soft palate closure (6 months) followed by hard palate closure (18 months)...

OBJECTIVE: Various biomaterials have been successfully applied in alveolar bone regeneration, however, the reconstruction of extensive osseous defects remains challenging and is often unfeasible with granular grafting materials. Several studies have outlined allogenic bone blocks as valid alternative to autologous block grafting. CLINICAL CONSIDERATIONS: In this report, we demonstrate the regeneration of two large osseous defects in the maxilla with allogenic bone blocks made from human donor bone...

BACKGROUND: After tooth loss, the posterior maxilla is usually characterized by limited bone height secondary to pneumatization of the maxillary sinus and/or collapse of the alveolar ridge that preclude in many instances the installation of dental implants. In order to compensate for the lack of bone height, several treatment options have been proposed. These treatment alternatives aimed at the installation of dental implants with or without the utilization of bone grafting materials avoiding the perforation of the Schneiderian membrane...

It is recognized that the mandibular reconstruction with free flap allows for both functional and aesthetic restoration. The flap must be used for reconstruction of a smooth lower mandibular contour and also the alveolar bone to allow dental rehabilitation. The double-barrel fibula free flap does respond well to these imperatives, but it increases risk of vascular complications. To overcome these risks, we propose a single-barrel fibula free flap, positioned at the alveolar level and a customized 3D implant, designed by computer-assisted surgery, at the basilar level...

PURPOSE: Achieving successful and predictable alveolar ridge augmentation in the vertical dimension is extremely challenging. Several materials have been investigated to achieve vertical ridge augmentation; however, the results are highly unpredictable. The collaborative team presenting this research has developed brushite- and monetite-based grafts that incorporate in their matrix a novel bone anabolic conjugate (C3) of a bisphosphonate and a potent bone-activating EP4 receptor agonist...

Over the years, there have been a series of innovative approaches to the alveolar bone augmentation techniques. These have led to the modifications of the existing methods and the establishment of more efficient ways to obtain sufficient bone mass that is necessary for the implant procedure. The aim of this paper is to propose a novel augmentation technique, and to investigate its efficacy, particularly during the healing process of the maxillary alveolar bone prior to the implant treatment. During the application of the proposed methodology, first, the ridge-split technique was applied to the posterior maxilla...

BACKGROUND: Tissue expansion of oral mucosa prior to ridge augmentation promises to reduce the soft tissue exposure and improve the final intraoral bone graft density and volume. This study explored a novel, shapeable hydrogel tissue expander (HTE) in intraoral sites that had undergone previous expansion and surgery. METHODS: Nine beagle dogs had all premolar teeth extracted with alveolar bone reduction. At least 3 months healing followed before placing the hydrogels at 4 sites for each dog: maxilla and mandible, right and left...
