RESUMO
Os implantes imediatos com estética imediata apresentam diversas
vantagens frente ao tratamento tradicional com carga precoce ou
tardia. Dentre as principais vantagens, pode-se citar o menor número
de intervenções cirúrgicas e a devolução mais rápida da estética
ao paciente. No entanto, um protocolo rígido deve ser seguido para
obtenção de sucesso em longo prazo. Este relato tem como objetivo
apresentar um caso de exodontias sem elevação de retalho com
implantação imediata e estética imediata. Ainda, a manutenção do
rebordo foi realizada com a utilização de enxerto xenógeno de lenta
taxa de substituição para compensar a remodelação fi siológica da
tábua óssea vestibular.

Minimally Invasive Aesthetic Area Tooth Removal Using Bioextractor® and Immediate  Implant Placement with Provisionalization: Case Report

Minimally Invasive Aesthetic Area Tooth Removal Using Bioextractor® and Immediate Implant Placement with Provisionalization: Case Report

Resumo

The tooth removal promotes itself a chain of reaction, leading to bone remodeling and compression of the alveolar ridge. The
technique used to extract can booth increase or decrease the amount of bone loss, even more when in the anterior area of the maxilla.
It is known that incisions and flap elevation associate with the use of traumatic devices, as elevators creates microfractures and loss
of blood supply in the buccal plate, in the other hand, minimal traumatic approaches, using vertical extractors device and flapless
technique can maintain the ridge architecture. If the minimally invasive technique is also associate with bone grafts, filling the gap
between implant and buccal plate with low rate bone substitute and sub epithelial connective tissue graft to improve the amount
of peri-implant soft tissue, the probability to achieve excellent aesthetic result is high.

This case report an atraumatic approach to
remove a fractured tooth in the aesthetic zone, using a new device to anchor and pull, vertically, the root, without compromising the
adjacent tissue. In order to decrease the morbidity of the treatment, immediate implant placement was done. The gap between the
implant and buccal plate was filled with hidroxiapatite, and the soft tissue amount increased with a connective tissue graft removed
from the palate. After 180 days, the prosthetic fase could be realized without complication or need of any surgical complement

Comparison of two anorganic bovine bone in maxillary sinus lift: a split-mouth study with clinical, radiographical, and histomorphometrical analysis

Comparison of two anorganic bovine bone in maxillary sinus lift: a split-mouth study with clinical, radiographical, and histomorphometrical analysis

Resumo

Background: Anorganic bovine bone (Bio-Oss®) has been extensively used for reconstruction of posterior area of
maxilla in sinus lift procedure; however, a new graft material (Lumina-Bone Porous®), that has a different
manufacturing process, has not been yet compared in clinical and histological terms. The manufacturing process of
bovine bone graft is related to size and porosity of the particles, and this can change osteoconductive property of
the material and bone formation. The use of Lumina-Porus® could improve bone formation, reduce the remaining
particles of the biomaterial using a low-cost material. The aim of this research was to compare the clinical,
radiological, and histomorphometrical results from maxillary sinus lift with two different anorganic bovine bone
substitutes Bio-Oss® (control) and Lumina-Bone Porous® (test).

Conclusion: Both materials Bio-Oss® and Lumina-Bone Porous® can be used in the maxillary sinus floor
augmentation with good predictability in clinical, radiographical, and histological point of view.
