Bone Augmentation With Occlusive Barriers and Cortical Particulate Allograft in Transverse Maxillary Defects: A Pilot Study International Journal of Morphology
Beltrán,Víctor; Engelke,Wilfried; Fuentes,Ramón; Decco,Oscar; Prieto,Ruth; Wilckens,Mario; Borie,Eduardo.
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...

Changes in Morphology of Alveolar Buccal Walls Following Atraumatic Internal Root Fragmentation International Journal of Morphology
Engelke,Wilfried; Beltrán,Víctor; Decco,Oscar; Valdivia-Gandur,Iván; Navarro,Pablo; Fuentes,Ramón.
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....
