| The centripetal resorption of maxilla is a continuous process after tooth loss. For treatment of deficient bone sites, autologous bone grafts may be used, as an alternative, biomaterials can be applied which do not require intra- or extraoral donor sites. The present report we describe the use of anorganic bovine bone (ABB) based on three case reports under different modes: Membrane, rigid barrier and connective tissue graft. Clinical results show that under all conditions, sufficient hard tissue was formed to allow implant born rehabilitation in the former insufficient bone sites. Histologic evaluation revealed trabecular bone in an almost mature matrix with resting particles of ABB. Depending on the original site situation, two step rigid occlusive... |

| The centripetal resorption of maxilla is a continuous process after tooth loss. For treatment of deficient bone sites, autologous bone grafts may be used, as an alternative, biomaterials can be applied which do not require intra or extraoral donor sites. The present report describes the use of occlusive barriers and cortical particulate allograft in transverse maxillary defects. This surgical approach was performed in five patients (4 females and 1 male, aged 20 to 37 years). Clinical results show that sufficient hard tissue was formed to allow implant born rehabilitation in the former insufficient bone sites. Histological evaluation revealed small amounts of newly formed bone with a predominance of collagen fibrous tissue and mature bone with very little... |

| La región anterior de la mandíbula generalmente se considera un área quirúrgica segura, con pocos riesgos de daño a estructuras anatómicas importantes. Sin embargo, esta región contiene un canal intraóseo, el canal incisivo de la mandíbula (CIM), que es la continuación del canal mandibular mesial al foramen mental, donde se encuentra el nervio incisivo de la mandíbula acompañado de estructuras vasculares. Su presencia y el curso de la inervación mandibular anterior siguen siendo un tema de debate y algunos autores incluso niegan su existencia. Este reporte define el curso anatómico del CIM bilateralmente mediante tomografía computarizada, confirmando la presencia del nervio incisivo de la mandíbula mediante técnica microquirúrgica asistida por endoscopía.... |

| The buccal alveolar wall represents the most important structure to provide shape and volume of the alveolous following tooth extraction. The aim of the study was the evaluation of buccal alveolar bone structures following minimally invasive surgery. In 15 patients (3 male, 12 female), aged 2067 years, 3 central incisors, 5 lateral incisors, and 7 bicuspids were removed using flapless enucleation. The enucleation comprised endoscopically assisted mesiodistal root sectioning with inward fragmentation of the oral and apical parts followed by internal reduction of the buccal root lamella. Buccal bone height before extraction was 10.61 mm, following extraction 10.50 mm. Crestal width of the buccal bone plate was 1.11 mm before and 1.40 mm after tooth removal.... |
