Ridge splitting for horizontal bone augmentation with Guided Bone Regeneration (GBR) and simultaneous implant placement

Horizontal lack of residual ridge width can complicate the implant procedures. Therefore, ridge construction prior to implant placement is a biomechanical requirement. Guided bone regeneration, bone grafting, alveolar ridge splitting and combinations of these techniques are used for the lateral augmentation of the alveolar ridge. The ridge splitting technique with simultaneous implant placement seems to be a minimally invasive treatment option for horizontal augmentation of narrow alveolar ridges with adequate vertical height. This paper thoroughly describes a segmental ridge splitting technique with both vertical and horizontal osteotomy cuts followed by the use of chisel and mallet to lateralise the buccal bone which was accompanied by GBR and simultaneous implant placement.

Periodontal Plastic Surgery

Periodontal Plastic Surgery comprises a limited number of surgical procedures which focus on the establishment of normal morphology and architecture of periodontal tissues in order to achieve aesthetical, biological and functional outcomes. The main surgical techniques concern the correction of morphology, position and amount of gingiva and in some cases the reconstruction and augmentation of alveolar ridge. Those surgical procedures include the treatment of gingival recession, surgical crown lengthening, augmentation of the width of attached gingiva and,the vertical or horizontal augmentation of alveolar ridge. Each surgical technique is followed by determined indications, contra-indications, advantages, disadvantages and, predictability.

Sinus lift, antral pseudocyst removal and horizontal bone augmentation using a bony lid - Case report

Purposes: Complex cases often require various treatment modalities that increase patients morbidity, treatment time and costs. In the present case we combined several techniques in order to perform a sinus lift, remove an antral pseudocyst and augment the site horizontally. Case report : A 69 year old female patient presented herself at our office looking for an oral rehabilitation solution. A need for sinus grafting as well a horizontal augmentation was noticed. An antral pseudocyst occupied a large portion of the right sinus. We removed a bony lid to access the sinus, aspirated the antral pseudocyst´s content and removed it through the Schneiderian membrane. After suturing it, the membrane was elevated, the sinus lift performed and the access window closed with a collagen membrane. The bony lid was used to augment the adjacent area. Implants were placed 4 months later. Conclusions : With the present method of treatment we were able to successfully perform a sinus lift, antral pseudocyst removal and bone augmentation, with a low morbidity, combined approach.

Horizontal Ridge Augmentation and Contextual Implant Placement with a Resorbable Membrane and Particulated Anorganic Bovine Bone-Derived Mineral

Alveolar ridge deficiency is considered a major limitation for successful implant placement. Various approaches have been developed to horizontal augmentation of bone volume. This case report presents the medium-term results of one-stage guided bone augmentation using an anorganic bovine bone (70%) and autologous bone (30%), placed in layers, in association with resorbable collagen membrane for a subsequent implant placement. The patient presented with a localized horizontal ridge defect in the posterior zone of the jaw. The clinical and radiographic presentations, as well as relevant literature, are presented.
